5.  Will Oracle Corporation, support complete custom install of Oracle9iAS components in Release 2 or in future releases?
Oracle9i Application Server Release 2 (9.0.2) provides the ability to choose the install type which fits best for a particular business usage.  Oracle believes that these install types addresses the most frequently deployed topologies needed by developers and enterprises.  There are no plans to provide any more granular custom install options at this time.

6.  Will Oracle Corporation, support custom deinstall of Oracle9iAS components in Release 2 or in future releases?
There are no plans to support custom or partial deinstall of Oracle9i Application Server instance.  All components that are part of a particular instance will be deinstalled as part of the Oracle9iAS deinstall process.

7.  Will Oracle Corporation, support specific Oracle9iAS component configurations in Release 2 or in future releases?
Oracle9iAS Release 2 (9.0.2) supports select Oracle9iAS component configurations, and will continue to do so in future releases.  For example, a user can select to configure just Oracle9iAS Portal without configuring Oracle9iAS Wireless.

8.  Will Oracle Corporation, support deconfiguration of any configured component, either from Oracle Enterprise Manager or by any other means?
There are no plans to support custom or select deconfigurations of components that form a Oracle9iAS instance.  For example, once the user configures Oracle9iAS Portal, it is not possible to deconfigure Portal later on.

9.  What does Oracle9i Application Server Install Type provide?
Oracle9i Application Server Install Type comprises of:

• J2EE and Web Cache: This install option, consists of HTTP Server with many mod extensions from Oracle, runtime environment to deploy Web Services, Java, J2EE, PL/SQl, C, C++, CGI applications along with caching capabilities.  It also includes complete management and JAAS security framework. 
• Portal and Wireless:  In addition to what J2EE and Web Cache provides, this install option consists of runtime environment to deploy Portal and Wireless applications along with DAV capabilities.
• Business Intelligence and Forms:  In addition to what Portal and Wireless provides, this install option consists of runtime environment to deploy full range of  Business Intelligence solutions and Forms applications.
• Unified Messaging:  In addition to what Business Intelligence and Forms provides, this install option consists of design time and runtime environment to deploy Unified Messaging solution.

• Oracle9iAS Metadata Repository:  An Enterprise Edition of Oracle9i Database Server consisting of a seed database that includes product, management and security metadata. 
• Oracle Internet Directory:  An LDAP based directory service that is central store of Oracle9iAS configuration information.
• Oracle9iAS Single Sign-On Server:  Enables single sign on capabilities for all types of applications.
• Oracle Management Server (OMS):  OMS is required to manage Oracle9iAS Metadata Repository, Oracle9iAS Forms Services and Oracle9iAS InterConnect.  All other components are managed by Oracle Enterprise Manager Website.

11.  What is the recommended memory and swap requirements for Oracle9iAS?

The following memory and swap space recommendations augment the minimums identified in the Installation Manual (Chapter 2).  These recommendations are characterized by install type.  They are based upon starting all components within each specific install type and running typical sample and demo applications. 

In considering your hardware requirements, please note, optimal sizing for an Oracle9iAS installation is unique based upon: 

• the profile of your Oracle9iAS installation (which components are configured 
• and utilized) 
• the size of your applications (such as the number of EJBs, Servlets, JSPs, 
• Forms, Reports, Portlets and how big they are) 
• the nature of your applications (largely transactional in nature vs 
• primarily read-only) 
• user load (number of concurrent users) 
• pattern of usage (peak usage vs low usage) 
• performance goals 

Memory and Swap Space recommendations for running the Mid-tier and Infrastructure on a single box

J2EE and Web Cache with Infrastructure:  Memory:  512MB RAM, Swap: 1GB 
Portal and Wireless with Infrastructure:     Memory:  1GB RAM, Swap: 1GB 
BI and Forms with Infrastructure:              Memory:  1GB RAM, Swap: 1GB 

Memory and Swap Space recommendations for running the Mid-tier and Infrastructure on separate boxes

J2EE and Web Cache:  Memory: 256MB RAM, Swap:  512MB 
Portal and Wireless:     Memory: 512MB RAM,  Swap:  1GB 
BI and Forms:              Memory: 1GB RAM, Swap: 1GB 
Infrastructure:               Memory:  512MB RAM, Swap: 1GB 

12.  What is a customer database? 
Oracle9iAS Release 2, refers to any database that contains operational data (also referred as raw data or regular data) as customer database.  In the earlier versions of Oracle9iAS,  it was also referred as origin database or backend database.  Out of the box, Oracle9iAS Metadata Repository contains all the metadata required by Oracle9iAS runtime components.  It is also possible to use the same Metadata Repository to contain operational data as well.

13.  Can I use an existing Oracle9i Database Server to contain, Oracle9iAS Metadata Repository seed database ?
No.  In Oracle9i Application Server Release 2 (9.0.2), it is not possible to populate Oracle9iAS Metadata Repository seed database into an existing Oracle9i Database Server.  This will be supported in the future releases of Oracle9iAS.

14.  Which Oracle9iAS Install Types can coexist on the same machine?
The following list outlines various Oracle9iAS Install Types that can coexist on a single host:

• One or more J2EE and Web Cache Install Types
• One or more Portal and Wireless Install Types
• One or more Business Intelligence and Forms Install Types
• One or more Unified Messaging Install Types
• Two or more installs of any combinations of J2EE and Web Cache, Portal and Wireless, Business Intelligence and Forms, Unified Messaging
• Any Oracle9i Application Server Install Type and Oracle9iAS Infrastructure
• One or more Oracle9iAS Infrastructure

• Every install has to reside in its own Oracle_Home.
• All installs on the same machine should be done by the same O/S user.
• Before the second or subsequent installs begins, Oracle Enterprise Manager should be shutdown.
• Each install should start a fresh instance of Oracle Universal Installer (OUI).  Multiple installs by clicking on Next Install button from End of Installation screen of OUI is currently not supported.

17.  Can Oracle9iAS instance and Oracle9iAS Infrastructure share the same HTTP Server?
HTTP Servers that are part of Oracle9iAS instances as well as Oracle9iAS Infrastructure, by default, are considered active.  If they are to work from the same web server, then manual configuration is needed.  Please refer to Oracle HTTP Server Administrator Guide, and Oracle9i Application Server Release Notes Addendum for more details.

18.  Can Oracle9iAS instances and Oracle9iAS Infrastructure exist on heterogeneous systems?
Yes, it is possible to run Oracle9iAS instances and Oracle9iAS Infrastructure on systems running different O/S.  For example it is possible to run Oracle9iAS instances on NT platform; whereas Oracle9iAS Infrastructure runs on Solaris box.

19.  Which other Oracle products can be installed along with Oracle9iAS on the same system?
Oracle9iAS coexists with Oracle8i Database Server, Oracle9i Database Server, Oracle E-business Suite as well as Oracle9iDS.  Furthermore, any Oracle9iAS mid-tier instances such as J2EE and Web Cache, Portal and Wireless, Business Intelligence and Forms, as well as Unified Messaging Install Types can coexist with Oracle9iDS - in the same Oracle_Home.  All other Oracle products reside in their own Oracle_Home.

20.  Which types of port conflicts does an Oracle9iAS install process detect?
Oracle9iAS Install process detects and resolves the following type of conflicts:

• Conflicts due to multiple Oracle9iAS Installs.
• Conflicts due to previous versions of Oracle9iAS.
• Conflicts due to any Oracle products either running or not running.
• Conflicts due to non-Oracle products that are running.

22.  How do I deal with Port 1521 conflicts that might arise during Oracle9iAS Infrastructure Installation process?
Port 1521 conflicts can happen under three circumstances:

• A non Oracle software uses this port:  If the conflict is due to a non Oracle application, please make sure that application is configured to use any port other than 1521.

• There is already an Oracle8i Database Server on the system:  If the conflict is due to an Oracle8i Database Server on the same system, please upgrade the Net8 listener to Oracle Net Listener which is a 9i based listerner software.  Please refer to "Oracle9i Application Server Installation Guide, Release 9.0.2" for more details on the upgrade process.  Once the upgrade is complete, the listener can be used both by Oracle8i and Oracle9i Database Servers.

• There is already an Oracle9i Database Server on the system: If the conflict is due to an Oracle9i Database Server on the same system, Infrastructure install can proceed with no additional work.  The Oracle9iAS Metadata Repository component of Oracle9iAS Infrastructure will use the same listener.

24.  What is a Primary Oracle9iAS Instance?
When multiple Oracle9iAS or Oracle9iAS Infrastructure installs are performed on a host, there is only one Oracle_Home which will contain the active Enterprise Manager Daemon to enable the Oracle Enterprise Manager Website.  All installations on a single host are administered by this Enterprise Manager.  The Instance which contains the active Enterprise Manager Daemon is referred to as the Primary Oracle9iAS Instance.

25.  How can I identify the Primary Oracle9iAS Instance?
On Solaris, check for ACTIVE_EMD_HOME entry in /tmp/emtab.  The Oracle_Home that contains this entry is the one from where Enterprise Manager is running.

26.  What happens when the Primary Oracle9iAS Instance is deinstalled?
Oracle recommends deinstallation of the Primary Oracle9iAS Instance be carried out after all other instances on the machine are deinstalled.  If for some reason, the Primary instance needs to be deinstalled, then the deinstall process will the prompt user to designate an alternate Primary instance from the remaining Oracle9iAS instances on the host.

27.  Do all Oracle9iAS Instances on the host have to share the same Oracle9iAS Infrastructure?
Yes, all Oracle9iAS Instances such as J2EE and Web Cache (only if clustering or single sign on features are used), Portal and Wireless, Business Intelligence and Forms, as well as Unified Messaging on the same host have to share the same Oracle9iAS Infrastructure.  The Infrastructure instance can either be on the same host or on a separate host.  When the instances share the same Oracle9iAS Infrastructure, they all join the same "Farm".

28.  Why am I prompted to enter the password for ias_admin user account during install?
The ias_admin user account gets created during the first installation on the host.  This is the management account used by Oracle Enterprise Manager.  This user account is also shared by all subsequent installations on the host.

29.  Why am I prompted for Oracle Internet Directory Credentials during install and how is it used?
Oracle Internet Directory is the central source of information for all Oracle9iAS instances.  Except for the J2EE and Web Cache Install type and Oracle9iAS Developer Kits install option, where Oracle9iAS Infrastructure use is optional, every Oracle9iAS install creates an instance object in Oracle Internet Directory, which needs credentials. 

30.  What type of Oracle Internet Directory credential is required to perform the above actions?
The user needs to belong to iASAdmins Group.  By default, the orcladmin user is a member of this group.  Note that the default password for the orcladmin user is the same as the ias_admin user password where the Internet Directory was installed.

31.  What is the restriction on hostname entry during Oracle9iAS installation process?
Oracle9iAS Install process expects to find the fully qualified host name as a second entry in some of Solaris system files such as:

• /etc/nodename
• /etc/hostname.hme0
• /etc/net/ticlts/hosts
• /etc/net/ticots/hosts
• /etc/net/ticotsord/hosts
• /etc/inet/ipnodes

32.  Why is there a restriction on the hostname entry?
During install time, many Oracle9iAS Component Config Tools run and retrieve the hostname from these system files.  These tools expects the entry to contain the fully qualified host name.

33.  Which components are installed with various Install Options?

Step 2:  Install and configure Oracle9iAS Infrastructure.
Step 3;  Install and configure Oracle9iAS middle tier installation.
Step 4:  Perform appropriate post install steps to configure middle tier components with the customer database.

47.  On Windows Platform, why am I prompted to run wsf.exe before Oracle9iAS installation can begin?
Oracle9iAS requires several files to be present in the Windows System folder. During the Oracle9iAS installation, these required files already present on the target
system are examined to ensure that they meet the requirements for Oracle9iAS. If any file has an outdated version, it will be replaced with a compatible version. 

Normally, replacement can be done during the Oracle9iAS installation, but if the file to be replaced is in use by another process at the time of installation, then the
installation will halt and an error dialog will appear. This is because Windows needs to restart for the updated file to take effect and the Oracle9iAS installation
routine cannot be interrupted by a system reboot during installation. 

Oracle9iAS includes a supplementary installation for the required Windows System Files. This Windows System Files installation will automatically reboot the
system if necessary at the conclusion of the system files installation. 

If you encounter a Windows System Files error during the Oracle9iAS installation, click OK to close the error dialog, then use the following instructions to run the
Windows System Files installation. You cannot proceed with the Oracle9iAS installation if you do not run the Windows System Files installation. 

To run the Windows System Files installation: 

   Step 1:  Click Exit to quit the Oracle9iAS installation. 

   Step 2:  Change to the root directory on the Oracle9iAS CD-ROM. 

   Step 3:  Run wsf.exe. 
Note:  The Windows System Files installation runs with a response file that utilizes an existing Oracle home or creates the home OUIHome if none is available. Windows restarts automatically, if it is required; otherwise the Windows System Files installation will end without displaying any Installation Finished dialog. 

   Step 4:  After Windows restarts or at the end of the Windows System Files installation, restart the Oracle9iAS installation.
