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.


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-managing, 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 ECPUs and the storage capacity in either GB's or TB's for the database. At any time, you may scale up or down the ECPUs or the storage capacity.

Autonomous Database supports four main types of workload:

Transaction processing and mixed workloads
Analytics and data warehousing
Transactions and analytics on JSON data
APEX Application Development

What is the difference between Dedicated vs. Severless deployments?

Serverless: With this option, you provision and manage only the Autonomous Database, while Oracle deploys and manages all the underlying infrastructure. Oracle autonomously operates all aspects of the database life cycle from database placement to backup and updates.

Dedicated: this offers a private cloud in the public cloud. A completely dedicated compute, storage, network and database service for only a single tenant. This offers a multitenant database architecture, allowing you to create and manage multiple Autonomous Databases within a single database system. Autonomous Database Dedicated is also available in customer's data centers with Exadata Cloud at Customer.

Where is Oracle Autonomous Database available?

The full list of data centers is shown here: Oracle Cloud Data Regions for Platform and Infrastructure Services.

You can view the maintenance event history for details about past maintenance events, such as the title, state, start time, and stop time. For more information, click here.

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

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

Oracle operations will monitor patching and rollback a patch if it 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).

Can I access the database server's operating system?

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


Does Autonomous Database offer a pre-migration check tool?

Yes. Oracle Autonomous Database uses a free tool called Cloud Premigration Advisor Tool (CPAT). This is a light-weight utility that analyzes the existing Oracle Database schemas and makes recommendations to ensure a successful migration to the Autonomous Database. For more information click here.

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

Oracle recommends using a logical migration approach to migrate existing Oracle Databases to Autonomous Database. For more information click here.

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.


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.

FAQs for Autonomous Database Dedicated

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


What is Autonomous Database Dedicated ?

Autonomous Database Dedicated (ADB-D) is a deployment choice that enables customers to provision autonomous databases into their own dedicated Exadata cloud infrastructure.

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 Dedicated and Autonomous Database Serverless?

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

With serverless (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. Serverless runs on Oracle Cloud Infrastructure.

With dedicated (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, 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 Serverless (ADB-S)?

ADB-S delegates all operational decisions to Oracle for the highest level of autonomous experience - think of a fully autonomous vehicle with no need for a steering wheel or cruise control. ADB Serverless (ADB-S) enables customers to quickly provision their own autonomous databases and become productive.

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 separates 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.


What is Autonomous Database on Exadata Cloud@Customer?

Autonomous Database on Exadata Cloud@Customer (or ADB-ExaC@C for short) is Autonomous Database Dedicated 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.


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.


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.


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.
