FAQs for Autonomous Database

This section includes a list of frequently asked questions that relate to Oracle Autonomous Database, i.e. the questions and answers cover both Autonomous Data Warehouse and Autonomous Transaction Processing. Below are sections covering each of these specific services.

GENERAL

What is the Oracle Autonomous Database?

Oracle Autonomous Database is the world’s first autonomous data management in the cloud to deliver automated patching, upgrades, and tuning—including performing all routine database maintenance tasks while the system is running—without human intervention. This new autonomous database cloud is self-driving, self-securing, and self-repairing, which helps to eliminate manual database management and human errors.

The Oracle Autonomous Database is fully elastic: You simply specify the number of OCPUs and the storage capacity in TB's for the database. At any time, you may scale up or down the OCPUs or the storage capacity.

What is the difference between a Dedicated Infrastructure vs. Shared Infrastructure deployment?

Dedicated deployment is a deployment choice that enables you to provision autonomous databases into their own dedicated Exadata cloud infrastructure, instead of a shared infrastructure with other tenants. Autonomous Database on Dedicated Infrastructure is also available in customer's data centers with Exadata Cloud at Customer.

With Shared Infrastructure deployment, which is the simplest configuration, you share the resources of an Exadata cloud infrastructure. You can quickly get started with no minimum commitment, enjoying quick database provisioning and independent scalability of compute and storage.

All deployment options (Shared, Dedicated in Oracle Cloud and Dedicated Cloud@Customer) are available with Autonomous Transaction Processing and Autonomous Data Warehouse.

How do I connect to the Oracle Autonomous Database?

ADB is built upon the Oracle Database, therefore, applications and tools that support Oracle Database also support ADB. These tools and applications connect to the service using standard database connectivity such as SQL*Net or JDBC. Click here for more information.

Are there any limitations on databases features or function in Oracle Autonomous Database?

Not all features present in Oracle Database Enterprise Edition are available in ADB; for example, database features designed for administration are not available. Please see Appendix B in both the Autonomous Data Warehouse documentationand Autonomous Transaction Processing documentation for the complete list.

If a customer wants to decommission their Oracle Autonomous Database instance will all data on disks, archive, backup etc. be safely removed?

The database instance will be dropped the moment the service is terminated. However, the database is restorable for up to 60 days, as legally required and documented in the Cloud Hosting and Delivery Policies. After that, the data is gone and cannot be recovered. Click here for more information.

Is it possible to setup access control lists (ACLs) in Oracle Autonomous Database?

Yes. it is now possible to specify an access control list that blocks all IP addresses that are not in the list from accessing the database. Once an access control list is set then that specific Autonomous Database only accepts connections from addresses in the access control list and rejects all other client connections. By default, when there is no network access control list specified the database is accessible from any IP address. Click here more information

Is it possible to control the list of database instances within a wallet?

Yes. On the Database Connection form, it is now possible to select type of wallet that will be generated:

  • Instance Wallet - provides a database-specific wallet with access to a single database only.
     
  • Regional Wallet - contains connection details for all ADBs within a given tenant-region.

Note that the instance (database-specific) wallet is the recommended option for applications where the connection is to only one system. Click here more information.

(Shared Infrastructure only)

Is it possible to invalidate a wallet?

Yes. This new wallet rotation feature makes it easy for customers to invalidate existing client certification keys for a specific ADW/ATP instance or for all Autonomous Database instances within a region. Click here more information.

AVAILABILITY

What is the current availability SLA for Oracle Autonomous Database?

The current SLA for ADB is 99.95% availability during any calendar month. There is an Extreme Availability option on the roadmap, which will offer 99.995% availability.

The pillar document provides more information about the specific definitions of key terms relating to the "Service Commitment", see here.

Does the backup process continue to run even if you shut down the database, for example to reduce costs?

A full back up will still happen. However, once the service has been stopped there is no need to do incremental backups because the database is not active.

What is the process to restore an Oracle Autonomous Database instance?

The restore process is very simple - select a specific point in time to restore via the management console.

Can a customer restore an Oracle Autonomous Database backup into another Database Cloud deployment?

No, you cannot restore an ADB backup into another cloud service. You can export an ADB database to an object store and then import into another service.

Can a customer use an Oracle Autonomous Database backup to restore a database to another/new Oracle Autonomous Database instance?

No, ADB backups can only be used to restore and recover to the same database. However, customers have the ability to clone a database and can choose to clone either the full database or only the database metadata.

Oracle Autonomous Database provides a manual backup option on the cloud console that takes a backup to the object store. What can I use this back up for? Can I restore it to my own database server?

No, the manual backup, which you must move to your object store bucket, can only be used by ADB. You can use the manual backup functionality for cases like backing up before a large data load.

Note, if you initiate a restore operation ADB may decide to use your object store backup rather than one of its automatic backups – if it will be faster to restore.

What happens if you cannot access Oracle Autonomous Database, i.e. the whole service is down?

Oracle is responsible for the service availability. Therefore, if the whole service goes down it’s Oracles responsibility to get the service back online ASAP.

What are the RTO/RPO SLAs for Oracle Autonomous Database?

Oracle does not provide RTO/RPO SLAs. ADB uses the fastest restore method (flashback database, automatic and manual backups) depending on the point-in-time specified for the recovery operation.

Does Oracle Autonomous Database provide DR/highly-available configuration?

No ADB does not currently provide a DR/HA configuration. However, it is on the roadmap.

Is it possible to clone production databases for development/test/QA environments?

Yes, ADB provides the ability to clone a database and you can choose to clone either the full database or only the database metadata.

Can the dev/test/QA cloned instances be masked?

Yes it is possible to use Oracle Data Safe data masking capabilities with cloned instances of ADB. For more information click here.

You can connect your on-premises network to ADB using FastConnect Public Peering and private endpoints

Using Private connectivity to Autonomous Database Dedicated Infrastructure deployment is supported.

Will clients need to upgrade their drivers?

Third party drivers must support Oracle Wallets and certificates. With ADBon Dedicated Infrastructure, both regular TCP and TCPS (Oracle Wallets and Certificate) connections are supported.

Details on connecting to ATP with via OCI, ODBC and JDBC can be found in the documentation.

Details on connecting to ADW with via OCI, ODBC and JDBC can be found in the documentation.

Are private Endpoints supported?

Yes, Private Endpoints are supported with ADB.

LOADING DATA

Is Oracle Data Integration via Oracle Cloud Marketplace supported with Oracle Autonomous Database?

Yes, Oracle data integration tools are configured to work with ADB.

What are the options for loading data into Oracle Autonomous Database?

There are multiple ways to load data into ADB:

ADB is integrated with multiple object storage services for data loading. You can upload your source files to one of these object-stores and use the PL/SQL API DBMS_CLOUD to load data into your database. ADB supports Oracle Cloud Infrastructure Object Storage, Oracle Cloud Infrastructure Object Storage Classic, AWS S3, and Azure Blob Storage for loading data. This is the recommended method for loading large data sets. SQL Developer also provides a data loading wizard that can load data from these object stores.

You can use Data Pump Import to load data from dump files. Data Pump Import is integrated with Oracle Cloud Infrastructure Object Storage, Oracle Cloud Infrastructure Object Storage Classic, AWS S3, Microsoft Azure Blob Storage. You can upload your dump files to one of these object-stores and import from those dump files.

You can also use client-side tools like SQL*Loader, or your in-house scripts to load data from files residing on your client machines.

Another option is to use Oracle tools and cloud services like GoldenGate, ODI, GoldenGate Cloud Service, and Oracle BI Data Sync.

Any 3rd party ETL tool that can connect to ADB using the security credentials wallet can also be used to load data.

Do customers need to upload data files to the Oracle Object Store for data loading?

For large data sets, uploading the source files to Oracle Object Storage and loading from the Object Store will most likely be faster than other options.

But you can use the other data loading options too depending on your use-case and requirements. Click here for more information.

Is GoldenGate on-premises and GoldenGate Cloud Service supported with ADB?

Yes, both GoldenGate on-premises and GoldenGate Cloud Service support ADB as a target system only.

ADB cannot be used as a source system for GoldenGate. Please see the GoldenGate documentation for configuring GoldenGate for replication to ADB.

Do I need to gather optimizer statistics after data loading?

ADB gathers optimizer statistics automatically if you are using the PL/SQL API DBMS_CLOUD, or if the tools and scripts you use to load data are using direct path loads. If you are using conventional DML operations to load data, then you will need to gather optimizer statistics yourself or let the nightly statistics gathering job gather statistics for objects that have stale statistics.

See the FAQ for both Autonomous Data Warehouse and Autonomous Transaction Processing for more details.

Does the data loading process support Avro files?

Yes. Autonomous Database can now read Avro files and parse the schema within the file to create the columns with the appropriate Oracle Database data types. Avro files may include complex types – like arrays, structs, maps and more; ADW supports avro files that containOracle data types. Click here for more information.

Does the data loading process support Parquet files?

Yes. Autonomous Database can now read Parquet files and parse the schema within the file to create the columns with the appropriate Oracle Database data types. Click here for more information.

Does the data loading process support pre-authenticated URLs?

Yes. If source files reside on the Oracle Cloud Infrastructure Object Storage it is possible to use Oracle Cloud Infrastructure pre-authenticated URIs. When a pre-authenticated request is created, a unique URL is generated. This unique URL can then be provided to users, partners, or third parties to access the Object Storage resource target identified in the pre-authenticated request.

SCHEMA DESIGN AND QUERYING

Does ADB come with any predefined data models?

There are no predefined data models in the ADB. You create your own schema, tables and other database objects as needed.

You can use SQL Data Modeler to design a new logical model and physical model, then generate the required DDL script(s) to implement your model in ADB. Click here for more information.

What's the algorithm for the automatic tuning?

The precise details of how autonomous capabilities are implemented inside ADB are considered proprietary and internal.

Can a customer create primary and foreign key constraints on tables in Oracle Autonomous Database?

Yes, you can create any constraint just like you do in a regular Oracle Database.

Can a customer create secondary indexes, partitioned tables, or materialized views?

Yes, you can create secondary indexes, partitioned tables, or materialized views in ADB.

For specific guidance on when this should be done, please see the specific FAQ sections for Autonomous Data Warehousing and Autonomous Transaction Processing.

MANAGING AND MONITORING

Is there an option to delay or reschedule patches?

For Shared Infrastructure deployments - No. Oracle patches ADB in maintenance windows. Currently, users cannot change the patching schedule. The date-time for the next scheduled maintenace is shown on the OCI console page for each instance.

With Dedicated Infrastructure deployments, you have the option to change the maintenance windows to control when the Exadata environments and the databases are updated.

If a quarterly patch has an adverse effect, who will notice (does Oracle monitor)? Will rollback be offered?

You cannot rollback patches yourself. Only Oracle operations can rollback a patch. Oracle operations will monitor patching and rollback if a patch cannot be applied successfully according to basic sanity tests. However, there is always a chance that the adverse effect is only observable from the application. In that case, you will have to notify Oracle via a Service Request(SR).

Does Oracle Autonomous Database have auto-scaling?

Yes, ADB on Shared Infrastructure does have auto-scaling and this enabled by default when you create a new instance. You can select auto scaling during provisioning or later using the Scale Up/Down button on the Oracle Cloud Infrastructure console. Click here for more information

Can I access the database server's operating system?

No. ADB does not allow access to the operating system.

How can I monitor database performance in Oracle Autonomous Database?

ADB provides the following monitoring consoles:

Oracle Management Cloud - supports monitoring Autonomous Databases via its Oracle Database Management console. This provides both monitoring and alerting for your Autonomous Database instances. The Performance Hub page provides both high-level and detailed performance metrics for your Autonomous Database instances. Use of Oracle Management Cloud is included as part of your Autonomous Data Warehouse and Autonomous Transaction Processing services. Click here for more information.

Performance Hub - provides real-time view of performance data directly on the OCI ADB console.

Performance Hub contains the following:

  • - Time Range field and time slider
  • - Active Session History (ASH) Analytics tab
  • - SQL Monitor tab
 

These features provides a simple one-click way to access the same information as found in EM Express, Oracle Management Cloud (OMC), and SQL Developer Web. The most likely target audience for this new feature will be cloud DBAs who manage a range of ADB instances within a single tenant and need a simple and fast way to monitor the performance of individual ADB instances directly from within the OCI Console. Click here for more information.

ADB Service Console - is a web-based service console for each database. Using this console, you can look at performance metrics like CPU storage utilization and monitor database activity. This console also provides real-time SQL monitoring for current and past SQL statements. Click here for more information.

Can I turn off Oracle Autonomous Database CPUs to save money?

Yes. You can do this by stopping the service from the cloud console or from the command line using the OCI APIs. This operation closes your ADB database, keeps your data in place, and stops charging for CPUs.

How long does it take to restart an instance after it has been stopped?

Starting an ADB instance is basically opening up your database. It is completed in seconds.

Can I create and set my own resource manager plan for workload management?

No. ADB provides a simple resource manager plan out of the box.

Can I modify the resource profiles for existing consumer groups (HIGH, MEDIUM, LOW, etc.)?

Yes. Autonomous Database allows customers to change the CPU/IO shares for the consumer groups within their ADB instance (high, medium, low, tp, tpurgent).

This allows for use cases where, for example, a workload running in the LOW resource group requires a greater share of CPU/IO resources.

Can I assign specific database users to specific database services (HIGH, MEDIUM, LOW, etc.) and prevent them from using other database services?

No. Any user can connect to any database service of their choice - providing they have a valid database username with the assoicated password.

Can I use Oracle Management Cloud to monitor my autonomous database instances?

Yes. Licenses to use the Database Monitoring features of Oracle Management Cloud are in included in your subscription to Autonomous Data Warehouse and Autonomous Transaction Processing.

MIGRATION

How can I migrate my existing Oracle Database to Oracle Autonomous Database?

Since an ADB database has some restrictions on the object types and Oracle Database Options you need to use a logical migration method rather than a physical one.

The main migration tool for migrating to ADB is Data Pump. You can export your schemas and import them into ADB using Data Pump. To sync up the additional/incremental changes on the source database during the export/import process you can use GoldenGate or GoldenGate Cloud Service to replicate those changes to ADB.

In the current release you cannot use physical migration methods like backup/restore, Data Guard, database clones, and transportable tablespaces to move your existing database to ADB.

Can I import an existing Oracle Database schema into Oracle Autonomous Database?

Yes. You can use Data Pump to export the source schema, move the dump files to the object store, and use Data Pump Import to load them into your ADB database.

Can I move my on-premises Oracle Database to Oracle Autonomous Database using RMAN backup and restore?

No, RMAN restore into ADB is not supported. You need to use one of the supported migration methods outlined above.

Can I use original export import methods (exp/imp) to migrate to Oracle Autonomous Database?

No,the original export/import methods are not supported in ADB. You need to use one of the supported migration methods outlined above or in the documentation.

How can I export my data from Oracle Autonomous Database?

You can use Data Pump export utility to unload data from ADB. For smaller data sets you can also use any SQL client tool to spool your data to a text file.

Does Autonomous Database support XML?

Yes. Oracle XML DB features are now supported in Autonomous Database. To ensure the security and the performance of Autonomous Data Warehouse and Autonomous Transaction Processing, some Oracle XML DB features are restricted so refer to the documentation for a complete list of supported features.

Does Autonomous Database offer a pre-migration schema check tool?

Yes. Oracle Autonomous Database Schema Advisor is a light-weight utility that analyzes the on-premise or cloud Oracle Database schemas for the suitability of migration to the Autonomous Database. The Advisor discovers the schema objects and performs deep analysis to highlight is any differences exist when the object gets created on Oracle Autonomous Data Warehouse or Oracle Autonomous Transaction Processing database.

The Advisor will run on pre-existing Schema and generates a report that highlights:

  • - The counts of discovered objects and a summary of migration status.
  • - Objects that cannot be migrated to the Autonomous Database due to the restrictions and lockdowns imposed by the Autonomous Database on certain data types, Database options and SQL statements/clauses.
  • - The Objects that will migrate with modifications that are automatically done during the import process or upon the execution of object creation DDL.
  • - Informational section containing certain best practice recommendations and guidance

PERFORMANCE

Does Oracle Autonomous Database automatically create indexes when needed?

If your ADB instance is using Database 19c then Automatic Indexing is available, however, it is not turned on by default.

Does Oracle Autonomous Database automatically create materialized views when needed?

No, in the current release ADB does not create materialized views automatically.

Can I specify the amount of memory I want for my database?

No, ADB configures the database memory (SGA and PGA) based on the number of CPUs you provision. Memory scales linearly with the number of CPUs.

What is the IO throughput in Oracle Autonomous Database?

IO throughput depends on the number of CPUs you provision and scales linearly with the number of CPUs. Scaling the service is quick and easy in ADB, if you need more IO throughput you can add more CPUs online in a few seconds.

How does Oracle Autonomous Database isolate different customers for performance and how does it make sure a customer's workload does not impact others?

ADB uses Database Resource Manager and IO Resource Manager to isolate resources for all databases. CPUs, memory, and IO resources are not over-provisioned in ADB, this makes sure every customer gets their assigned amount of resources at all times.

Does Oracle Autonomous Database open a database on multiple nodes or a single node? Does it depend on the number of CPUs?

ADB may decide to open a database on a single node or multiple nodes. ADB does not expose these details because it is not necessary to know about this level of detail.

Where are the parallel processes running for a parallel query, on a single node or multiple nodes?

ADB decides where to run a query and where to spawn the parallel processes, it may be on a single node or multiple nodes. Customers do not need to know about these implementation details since ADB controls this automatically.

It is possible to change the CPU/IO shares for the consumer groups?

Yes it is possible to change the CPU/IO shares for the consumer groups within their ADB instance (high, medium, low, tp, tpurgent). This allows for use cases where, for example, a workload running in the LOW resource group requires a greater share of CPU/IO resources than HIGH and MEDIUM.

The 'Set Resource Management Rules' pop-up form on the administration section of the service console has been extended to allow the modification of CPU/IO shares across the different resource groups. It is also possible to change the resource shares within a script, application call and/or via a SQL prompt using the cs_resource_manager package.

FAQs for Autonomous Data Warehouse on Shared Infrastructure

This section includes a list of frequently asked questions that relate specifically to Oracle Autonomous Data Warehouse on Shared Infrastructure.

GENERAL

What is Autonomous Data Warehouse?

Oracle Autonomous Data Warehouse provides a fully-managed database that is tuned and optimized for data warehouse workloads.

As a fully-managed service, all database lifecycle operations are managed by the service: the creation of the data warehouse database, the backups of the database, the patching and the upgrading of the database, and the growing or the shrinking of the database.

Oracle Autonomous Data Warehouse is fully elastic: You simply specify the number of OCPUs and the storage capacity in TB's for the data warehouse. You may scale up or down the number of OCPUs or the storage capacity at any time with no downtime.

ADW offers two deployment options:

Shared - With Shared Infrastructure multiple customers share the resources of a single Exadata Cloud Infrastructure.

Dedicated - With Dedicated Infrastructure, a customer's ADW databases are provisioned on a dedicated Exadata Cloud Infrastructure, with no shared resources, isolated from other tenants.

Is it possible to connect existing tools and application to Autonomous Data Warehouse?

Yes, Oracle Autonomous Data Warehouse is built upon the Oracle Database, so business intelligence applications and tools that support Oracle Database also support Oracle Autonomous Data Warehouse. These tools and applications connect to the service using standard database connectivity such as SQL*Net or JDBC. Click here for more information

Where can I get more information about ADW?

More information about Autonomous Data Warehouse is available on oracle.com and via the ADW documentation

Are there any hands-on lab available for ADW?

Yes. There is a comprehensive set of hands-on labs for ADW which covers everything you need to get started. For the getting started workshop click here for more information.

For the advanced workshop click here for more information.

Is there a technical forum where customers can post questions relating to ADW?

Is Database In-Memory option available in ADW?

Customers cannot use the features of the database In-Memory option. Internally, ADW uses some of the key features of Database In-Memory to optimize performance.

LICENSING

Can a customer use the machine learning features ADW if they choose the BYOL option but have not previously licensed Oracle Advanced Analytics?

Licenses for Oracle Advanced Analytics are not required for BYOL. However, note that, currently, R Enterprise is not included or supported with ADW.

SCHEMA DESIGN AND QUERYING

Which data models does ADW support? Is there a recommended data modelling technique for ADW?

ADW supports all the usual schema models such star schema, snowflake and 3NF. The same basic design concepts still apply when designing the data warehouse/data mart schema. The main difference between the ADW and a non-autonomous Oracle Database is that you do not need to specify the physical properties of tables (e.g., partitioning, indexes, compression, storage details etc.).

Can a customer create indexes on tables?

The CREATE INDEX statement is supported in ADW. Howver, ADW uses other techniques such as Exadata smart scan and storage indexes to quickly locate data. ADW will automatically create, maintain and delete indexes in certain cases such as with enforced and enabled primary key constraints.

Can users create primary and foreign key constraints on their tables?

Yes, users can create any constraint just like they do in a regular Oracle Database.

Does ADW include all the usual analytic SQL features?

Yes. The usual in-database analytic SQL features are included with ADW.

Can a table be partitioned? Does the ADW automatically partition tables?

Yes, customers can manually create any type of partitioned table in ADW. Note that ADB does not provide automatic partitioning. Instead, ADW creates tables using the column store format which is automatically managed by the database and provides very fast access to data.

Can the parallelism settings be changed for queries on ADW?

ADW configures parallelism out of the box based on the number of CPUs you provision. This means there is no need to explicitly configure parallelism.

But, if required you can include parallelism hints in your queries and enable those hints by setting a database parameter.

Oracle recommends using the default settings for optimum performance.

Is it possible to track user load operations and view the BAD and LOG files?

You have complete control over the reject reject limits from within the SQL Developer data loading wizard and using the command-line approach. This provides control for whether a load fails with the very first row being rejected or whether a specific number of errors can be tolerated and possibly reviewed later. The default reject limit is set to zero to ensure highest level of data completeness. Click here for more information.

Is support for R and Python on the roadmap?

Yes. Support for both R and Python is on the roadmap.

Where can I find more information on the SQL notebook tool Oracle Machine Learning (OML)?

There are links to tutorials and videos for OML within the Getting Started section on the OML documentation. Click here for more information

Oracle ML SQL Notebook contains a range of example notebooks covering the most commonly used data mining features. These are all prepared and managed by the Machine Learning product management team. Additional examples are also available via Github, click here for more information.

MIGRATION

Can an AWS Redshift database be migrated to ADW?

Yes, SQL Developer provides a migration wizard for AWS Redshift as it does for other databases. This wizard connects to the source Redshift database, exports the metadata and the data to AWS S3, and imports them into ADW. It also allows you to save the migration scripts and run them outside of SQL Developer anywhere you want. Click here for more information

TOOLS AND APPLICATION SUPPORT

Which 3rd party business intelligence tools are supported on the ADW?

As a general rule, any business intelligence tool that connects to the Oracle Database using an OCI 'thick' connection or a JDBC thin connection with support for wallets should work with ADW. Oracle has partnered with many 3rd party developer to test and certify tools and connectivity solutions with ADW. Click here for more information.

FAQs for Autonomous Transaction Processing on Shared Infrastructure

This section includes a list of frequently asked questions that relate specifically to Oracle Autonomous Transaction Processing on Shared Infrastructure.

GENERAL

What is Autonomous Transaction Processing?

Oracle Autonomous Transaction Processing is one of a family of cloud services built on the self-driving, self-securing, and self-repairing Oracle Autonomous Database. Autonomous Transaction Processing (ATP) enables businesses to safely run a complex mix of high-performance transactions, reporting, batch, and machine learning along with simpler and faster application development on the Oracle Database on Exadata in the cloud.

ATP automates patching, upgrades, and tuning without human intervention or downtime. Users can instantly create new ATP databases and easily convert existing databases, dramatically reducing costs and time to market.

ATP is also fully elastic: you can instantly and independently, scale the compute or storage, so only the required resources are provisioned at any given time, decreasing runtime costs.

ATP offers two deployment options:

Shared - With Shared Infrastructure multiple customers share the resources of a single Exadata Cloud Infrastructure.

Dedicated - With Dedicated Infrastructure, a customer's ATP databases are provisioned on a dedicated Exadata Cloud Infrastructure, with no shared resources, isolated from other tenants.

Where can I get more information about ATP?

More information about Autonomous Transaction Processing is available on oracle.com and via the ATP documentation

Are there any hands-on lab available for ATP?

Yes. There is a comprehensive set of hands-on labs for Autonomous Database on github which covers everything you need to get started. For the getting started workshop click here for more information - note that this lab refers to ADW but the same concepts apply to ATP.

For the advanced workshop click here for more information - note that this lab refers to ADW but the same concepts apply to ATP.

There is a more developer-centric workshop click here for more information - note that this lab refers to ATP on Dedicated Exadata Infrastructure but the same concepts apply to ATP on Shared Exadata Infrastructure.

Are there any limitations on databases features or function in ATP?

Not all features present in Oracle Database Enterprise Edition are available in ATP; for example, database features designed for administration are not available. You can find a complete list of the features that are not supported in the ATP documentation.

Is there a technical forum where customers can post questions relating to ATP?

Yes, ATP has a technical forum on Oracle Cloud Customer Connect. Customer Connect is a community-gathering place for our cloud customers to interact and collaborate on common goals andobjectives. Cloud Ops will use the forum to update customers about patching schedules and details of patch contents.

Where can I get more information about ATP?

More information about ATP is available on cloud.oracle.com and in the ATP documentation.

CONNECTING

How do I connect to the service?

ATP is built upon the Oracle Database; applications and tools that support Oracle Database also support ATP. These tools and applications connect to the service using standard database connectivity such as SQL*Net or JDBC.

Note, all communications with the database are encrypted and users are required to download a wallet file after creating the ATP Shared Infrastructure instance, which contains the necessary credentials, to establish a connection.

Click here for more information.

Where should application servers be provisioned in order to avoid network latency?

Application servers should be provisioned in the same Oracle Cloud Infrastructure Region.

What pre-defined database services are available with ATP?

ATP comes with 5 preconfigured database services, HIGH, MEDIUM, LOW, TP and TPURGENT. The services control the priority of the sessions when the system is under resource pressure and some control the parallel degree used. By default, queries will execute serially when connected to the TP, TPURGENT and LOW services.

Users can specify a parallel degree on an object or uses optimizer hints to trigger parallel execution to be used when connected to the TP and TPURGENT services. Queries will be automatically executed in parallel when sessions are connected to the HIGH and MEDIUM services. There is also a limit on the number of concurrent sessions that can execute on the HIGH and MEDIUM services.

SCHEMA DESIGN AND QUERYING

Can a customer create primary and foreign key constraints on tables in ATP?

Yes, customers can create any constraint just like they do in a regular Oracle Database.

Can a customer create secondary indexes on tables in ATP?

Yes, customers can create both B-Tree or Bitmap indexes on any table.

Does ATP automatically create indexes?

Yes, where the database version is 19c which is required for Auto-Indexing. Note that auto-indexing is not on by default.

Can a table be partitioned in ATP?

Yes, customers can create any type of partitioned table.

Does ATP automatically partition tables?

No, not in the initial release of the services.

Can a customer create a materialized view in ATP?

Yes, customers can create any materialized view.

Does ATP automatically create materialized views?

No, not in the initial release of the services.

Does ATP have full PL/SQL support?

Yes,customer can utilize nearly all the PL/SQL capabilities. The small set of limitations is listed in the documentation,

FAQs for Autonomous Database on Dedicated Infrastructure

This section includes a list of frequently asked questions that relate specifically to Oracle Autonomous Database on Dedicated Infrastructure.

GENERAL

What is Autonomous Database on Dedicated Infrastructure?

Autonomous Database on dedicated infrastructure (ADB-D) is a deployment choice that enables customers to provision autonomous databases into their own dedicated Exadata cloud infrastructure, instead of a shared Exadata infrastructure with other tenants.

ADB-D provides the customer customization over operational polices, including software and hardware isolation for the highest levels of performance and security governance; it is well suited for customers wanting to deploy Oracle Autonomous Database in cloud with common enterprise lifecycle controls and especially ideal for customers who want a self-service capability via their own database cloud. ADB-D is available in the Oracle Cloud and in the customer’s data center with Exadata Cloud@Customer.

What is the difference between Autonomous Database on Dedicated Infrastructure and Autonomous Database on Shared Infrastructure?

Autonomous Database cloud services offer two infrastructure choices, shared and dedicated:

With shared infrastructure (ADB-S), the simplest configuration, multiple customers share the resources of an Exadata cloud infrastructure. These customers can quickly get started with no minimum commitment, enjoying quick database provisioning and independent scalability of compute and storage. Shared infrastructure runs on Oracle Cloud Infrastructure.

With dedicated infrastructure (ADB-D), the customer must first subscribe to a dedicated Exadata cloud infrastructure that is isolated from other tenants, with no shared processor, memory, network or storage resources. This infrastructure choice offers greater control of the software and infrastructure lifecycle, customizable policies for separation of database workload, software update schedules and versioning, workload consolidation and availability policies. Dedicated infrastructure is available on Oracle Cloud Infrastructure and Exadata Cloud@Customer.

Both Autonomous Database infrastructure options ensure high availability, exceptional performance, and multi-level security.

When should I use ADB Dedicated (ADB-D) versus ADB Shared (ADB-S)?

ADB shared (ADB-S) offers an ultra-simple and elastic database deployment in the cloud, it enables customers to quickly provision their own autonomous databases and become productive with new application development. ADB-S delegates all operational decisions to Oracle for the highest level of Autonomous experience, think of an autonomous vehicle with no need for a steering wheel or cruise control.

ADB dedicated (ADB-D), on the other hand is more like an autonomous vehicle that still includes a steering wheel and cruise control. ADB-D offers greater control and isolation starting at the Exadata cloud infrastructure level, with customizable maintenance schedules, software update versions, backup retention periods, etc. ADB-D allows customers to group and separate out databases based on organizational structure and criticality of application workload. ADB-D is ideal for customers looking to deliver a self-service database capability within their own database cloud environment running either on the public cloud or in the customer’s data center. Using this model, customer fleet administrators can use the steering wheel and cruise control (customized operational policies) to tailor an operational plan for different parts of their organization, then the organization consumes via a self-service experience similar to the vehicle with no need for a steering wheel or cruise control.

What types of database workload are best to run on ADB Dedicated?

You can run all your data warehousing (ADW-D), transaction processing or mixed workload (ATP-D) databases of any size, scale or criticality on ADB dedicated. As well as supporting databases that may require highest governance, consistent performance and operational controls.

With Exadata Cloud@Customer deployment, ADB dedicated is ideal for on-prem customers desiring Autonomous Database but cannot move to the public cloud due to data sovereignty, corporate policies, network latency and security requirements etc.

Can I run both Autonomous Transaction Processing and Autonomous Data Warehouse databases on ADB Dedicated?

Yes, you can have a mix of ATP-D and ADW-D databases on the same ADB dedicated Exadata rack.

Are there any limitations on database features or functions with ADB Dedicated?

Not all features present in Oracle Database Enterprise Edition are available in ADB-D; for example, database administration features are not available. Please see Autonomous Database dedicated documentation for the complete list.

CLOUD@CUSTOMER

What is Autonomous Database on Exadata Cloud@Customer?

Autonomous Database on Exadata Cloud@Customer (or ADB-ExaC@C for short) is Autonomous Database on dedicated Infrastructure running on Gen 2 Exadata Cloud@ Customer for on-premises deployment. It is the same ADB dedicated cloud service as on Oracle Cloud Infrastructure except it runs in the customer’s data centers. This is for customers desiring Autonomous Database but cannot leverage the public cloud due to sovereignty laws, industry regulations, corporate policies, network latency and security requirements, or customers that have on-premises applications that are tightly coupled with databases running locally.

What are the key differences between Autonomous Database Dedicated on Oracle Cloud Infrastructure and Autonomous Database on Exadata Cloud@Customer?

It is the same Autonomous Database dedicated cloud service running on 2 different platforms. Both services are managed via the same interface, OCI Console, CLI and REST APIs. They have the same feature set; however new features on these platforms will have different release dates.

The key differences are:

  • Network configuration: On OCI, networking is configured via VCN by the customer. On ExaC@C, this requires setting up connectivity to the cloud control plane and defining the Exadata system primary and client networks which the Oracle field engineer will validate on-site.
  • Backup locations: On OCI, only object storage is supported. On ExaC@C, customers have the option to backup to object storage, local Exadata storage, customer’s network attached storage (NFS) and customer’s ZDLRA.

Who is responsible for the backup and restore for Autonomous Database on Exadata Cloud@Customer?

Oracle Autonomous Database is responsible for backup and restore operations, and the management of object storage and local Exadata storage. Backup and restore using customer managed storage (NFS and ZDLRA) are the customer’s responsibility.

Who is responsible for the patching the Autonomous databases on Exadata Cloud@Customer?

Oracle Autonomous Database is responsible for patching both the Exadata and user databases (Dom0 and DomU); customers has the option to override the default patching schedule with their preferred schedule.

Can I deploy a mix of Exadata Database and Autonomous Database on Exadata Cloud@Customer?

In the first release, customer must designate whether an ExaC@C rack is for Autonomous Database or Exadata Database. Supporting a mix of Autonomous Database and Exadata Database is a roadmap item for CY 2021.

ARCHITECTURE

What are the shapes of the Exadata Cloud Infrastructure racks that are available for ADB Dedicated on OCI?

X8 and X7 Exadata Infrastructure Quarter, Half and Full Racks are supported. See here for details about the capacities and characteristics of these systems.

What are the shapes of the Exadata Infrastructure racks that are supported on ADB on Exadata Cloud@Customer?

Gen 2 Exadata Cloud at Customer Infrastructure Quarter, Half and Full Racks are supported.

Note: ADB are not available on Base System and Gen 1 Exadata Cloud at Customer Infrastructure. See here for details about the capacities and characteristics of these systems.

If I have an Exadata X8 Quarter Rack, how many total OCPUs are available for ADB-D databases?

Exadata Infrastructure on an X8 Quarter Rack has 100 enabled CPU cores; therefore, it can support as many databases as it has CPU cores, i.e. 100 databases.

When ADB-D supports fractional OCPUs/overprovisioning, you will be able to have up to 10 databases running on a single CPU core, however you can only have a maximum of 200 databases within each Autonomous Container Database provisioned for High Availability deployment.

How many Autonomous Container Databases and Autonomous Databases are supported on ADB Dedicated?

You can have up to 12 autonomous container databases with a maximum of 200 autonomous databases on Half and Full rack, and 100 autonomous databases for Quarter rack per container database for the high availability configuration.
See here for more info.

MANAGING and MONITORING

What is the role of a Fleet Administrator in ADB Dedicated?

Fleet administrator is a logical service role (managed by IAM privileges) responsible for the creation and the management of Autonomous Exadata Infrastructure (AEI) and Autonomous Container Database (ACD) resources for dedicated deployments. On Exadata Cloud@Customer, the fleet administrator is also responsible for provisioning and managing Backup Destinations and Autonomous Exadata VM Cluster. These resources must be created before dedicated Autonomous databases can be created.

The logical role is materialized by granting IAM privileges to a group of users (a Fleet Administrator Group) to manage the AEI and ACD resources. Please see Fleet Administrator’s Guide to Autonomous Database Dedicated Deployments for more information.

What is the role of a Database Administrator in ADB Dedicated?

Database Administrator is both a logical service user role (managed by IAM privileges) and a Database User role responsible for the creation, monitoring and management of Autonomous databases. In order to manage the Autonomous Database resource, the service role must also be able to at a minimum USE Autonomous Container Database resources, which must be visible to assign as the target for the ADB during provisioning.

Database Users are in essence application developers, users who can connect to and use an Autonomous Database to store and access the data generated by applications. Database Users are not managed by IAM like service users, rather they are managed by capabilities built natively into the Autonomous Database. A Database Administrator is an IAM service user who is also a special case Database User, a user with the highest level of ADB privileges.

The Database Administrator can create, connect and manages schema and user access to autonomous databases.The Database Administrator has the exact same responsibilities in ADB-D as in ADB-S.

Can I use Enterprise Manager to monitor ADB Dedicated instances?

Yes, you can use on-prem EM 13.3+ or the OCI Marketplace EM 13c Image to monitor both ADB Dedicated on OCI and Autonomous Database on Exadata Cloud@Customer
For more information, refer to the EM Cloud Control Administrator’s Guide for Oracle Autonomous Databases.

PRICING and LICENSING

How is ADB Dedicated priced?

There are two components:

1. Infrastructure: subscribe to Exadata Cloud Infrastructure for Oracle Cloud Infrastructure deployment or Exadata Cloud at Customer Infrastructure for Cloud at Customer deployment

2.Database OCPUs: subscribe to hourly per active OCPU consumed, using either license included or BYOL license type. Billing happens monthly at an aggregate level, total of all active OCPUs, for each Exadata Cloud Infrastructure resource.

ADB-D on OCI pricing details can be found on the Autonomous Database pricing pages ( ATP / ADW). ADB on ExaC@C pricing details can be found on the Exadata Cloud@Customer pricing page

Where is the database license type defined on ADB Dedicated?

On OCI, this is defined at the Exadata Infrastructure level. On ExaC@C, this is defined at the Autonomous VM Cluster level. Hence today, you can only use one license type (License included or BYOL) on an Exadata rack until Multiple VM Clusters per rack is supported on ADB-D and ADB-ExaC@C resp.
