2.2 Oracle Application Server 10g Upgrade-Related Considerations

When you are upgrading your Oracle Application Server 10g environment to Oracle Fusion Middleware 11g, you will likely update one area of your environment at a time.

For example, you might upgrade the middle tiers in one department to Oracle Fusion Middleware 11g in order to support new Oracle SOA Suite features. At the same time, you might leave your company-wide Oracle Identity Management components at Oracle Application Server 10g.

For information about the Interoperability between the Oracle Fusion Middleware 11g suites and the equivalent installation types available in Oracle Application Server 10g, see Table 2-1, "Oracle Fusion Middleware 11g Compatibility Matrix".

The following sections describe some common compatibility issues that can arise during the upgrade process:

Section 2.2.1, "Oracle HTTP Server Interoperability"
Section 2.2.3, "Oracle Identity Management Suite Interoperability"

2.2.1 Oracle HTTP Server Interoperability

Table 2-2 describes the upgrade-related interoperability of Oracle HTTP Server with other Oracle Fusion Middleware components at the same patch level. For example, the Standalone Oracle HTTP Server 10.1.3 would be interoperable with ADF, SOA and WebCenter 10.1.3 as shown below.

Table 2-2 Oracle HTTP Server Interoperability

	Standalone OHS 10.1.3	Standalone OHS 10.1.2	Integrated OHS 10.1.2	OHS 11gR1
Forms, Portal, Reports, Discoverer 10.1.2
Forms, Portal, Reports, Discoverer 11gR1
ADF, SOA, WebCenter 10.1.3
ADF, SOA, WebCenter 11gR1

The following sections describe the upgrade-related interoperability capabilities and limitations of Oracle HTTP Server 10g and Oracle HTTP Server 11g:

Limited Support for Oracle HTTP Server 10g with Oracle WebLogic Server
No Support for Oracle HTTP Server 11g with Oracle iAS 10g Components

2.2.1.1 Limited Support for Oracle HTTP Server 10g with Oracle WebLogic Server

Two different versions of Oracle HTTP Server were available with the Oracle Application Server 10g Release 2 (10.1.2) and 10g Release 3 (10.1.3):

The integrated Oracle HTTP Server, which was installed and configured automatically with the 10g Release 2 (10.1.2) and 10g Release 3 (10.1.3) components by Oracle Universal Installer. This integrated version of the Oracle HTTP Server was based on Apache 1.3.
The standalone, separately-installed Oracle HTTP Server, which was available on the 10g Release 2 (10.1.2) and 10g Release 3 (10.1.3) Companion CD-ROM. This standalone version of Oracle HTTP Server was based on Apache 2.0.

The interoperability capabilities and restrictions for the integrated Oracle HTTP Server and the standalone Oracle HTTP Server are different:

The integrated Oracle HTTP Server for 10g Release 2 (10.1.2) and 10g Release 3 (10.1.3) is based on Apache 1.3 and currently is not certified for use with Oracle WebLogic Server for Oracle Fusion Middleware 11g.

As a result, you cannot configure the integrated Oracle HTTP Server to route requests to Oracle WebLogic Server 11g.
The standalone Oracle HTTP Server is based on Apache 2.0, which is certified with Oracle WebLogic Server 11g.

As a result, you can configure the standalone Oracle HTTP Server to route requests to Oracle WebLogic Server by following the same instructions as you would for Apache 2.0.

Note:
For more information, see Oracle Fusion Middleware Using Web Server Plug-Ins with Oracle WebLogic Server.

2.2.1.2 No Support for Oracle HTTP Server 11g with Oracle iAS 10g Components

Oracle HTTP Server 11g is not compatible with Oracle iAS 10g components because the required mod_oc4j module is not compatible with Oracle HTTP Server 11g.

As a result, do not upgrade your Oracle HTTP Server instances to 11g until after you have upgraded your Oracle iAS 10g components to 11g.

2.2.2 Oracle Web Cache Interoperability

Table 2-3 describes the upgrade-related interoperability of Oracle Web Cache with other Oracle Fusion Middleware components.

Table 2-3 Oracle Web Cache Interoperability

	Standalone Web Cache 10.1.2	Integrated Web Cache 10.1.2	Web Cache 11gR1
Forms, Portal, Reports, Discoverer 10.1.2
Forms, Portal, Reports, Discoverer 11gR1
ADF, SOA, WebCenter 10.1.3
ADF, SOA, WebCenter 11gR1

2.2.3 Oracle Identity Management Suite Interoperability

Table 2-4 describes the upgrade-related interoperability of Oracle HTTP Server 10g with other Oracle Fusion Middleware components

Table 2-4 Oracle Identity Management Suite Interoperability

	Oracle Internet Directory 10.1.2.3	Oracle Internet Directory 10.1.4.3	Oracle Internet Directory 11gR1
OSSO 10.1.2.3 See Section 2.2.3.1, "Interoperability of Oracle Internet Directory 11g and Single Sign-On 10g"
OSSO 10.1.4.3 See Section 2.2.3.1, "Interoperability of Oracle Internet Directory 11g and Single Sign-On 10g"
Forms, Portal, Reports, Discoverer 10g See Section 2.2.3.3, "Oracle Application Server 10g Dependencies on Oracle Identity Management 10g"
Forms, Portal, Reports, Discoverer 11gR1 See Section 2.2.3.3, "Oracle Application Server 10g Dependencies on Oracle Identity Management 10g"

This section provide answers to specific Oracle Identity Management Interoperability issues:

Interoperability of Oracle Internet Directory 11g and Single Sign-On 10g
Oracle Application Server 10g Dependencies on Oracle Identity Management 10g
Oracle Identity Management 10g Components in a Collocated Home

2.2.3.1 Interoperability of Oracle Internet Directory 11g and Single Sign-On 10g

Oracle Fusion Middleware 11g (11.1.1.4.0) provides an upgrade path for Oracle Application Server Single Sign-On users. Specifically, you can upgrade your Oracle Application Server Single Sign-On environment to Oracle Access Manager 11g.

You can also continue to use your existing Oracle Application Server Single Sign-On 10g environment with your newer Oracle Fusion Middleware 11g components. However, after upgrading your Oracle Internet Directory (and Oracle Directory Integration Platform) instances to 11g, there are some post-upgrade tasks required in order for Oracle Application Server Single Sign-On 10g to work successfully with the upgraded Oracle Internet Directory instance.

For more information, follow the instructions for upgrading Oracle Internet Directory and Oracle Directory Integration Platform in the Oracle Fusion Middleware Upgrade Guide for Oracle Identity Management.

2.2.3.2 Oracle Identity Management 10g Components in a Collocated Home

A collocated Oracle Identity Management 10g Oracle home contains all four of the primary Oracle Identity Management 10g components (Oracle Internet Directory, Oracle Directory Integration Platform, Oracle Application Server Single Sign-On, and Oracle Delegated Administration Services). However, you can upgrade only Oracle Internet Directory and Oracle Directory Integration Platform to 11g.

As a result, after you upgrade Oracle Internet Directory and Oracle Directory Integration Platform to a new 11g Oracle instance, you must then decommission the Oracle Internet Directory and Oracle Directory Integration Platform instances in the 10g Oracle home.

For complete information about the required post-upgrade tasks for Oracle Internet Directory and Oracle Directory Integration Platform, see "Upgrading Your Oracle Internet Directory Environment" in the Oracle Fusion Middleware Upgrade Guide for Oracle Identity Management.

Note:

The Oracle Fusion Middleware Upgrade Guide for Oracle Identity Management provides additional information about the required upgrade tasks for Oracle Identity Management components. Refer to this guide before you begin your upgrade planning.

2.2.3.3 Oracle Application Server 10g Dependencies on Oracle Identity Management 10g

Some of the components in Oracle Application Server 10g Release 2 (10.1.2) depend upon specific Oracle Identity Management 10g components. As a result, you should consider the following when you upgrade Oracle Identity Management or Oracle Portal, Forms, Reports, and Discoverer to Oracle Fusion Middleware 11g:

If you upgrade the Oracle Portal, Forms, Reports, and Discoverer middle tier components to 11g before you upgrade the associated Oracle Identity Management components, then there are no known interoperability restrictions.
If you upgrade the Oracle Identity Management components to 11g before you upgrade the Oracle Portal, Forms, Reports, and Discoverer components, then the only restriction to consider is when the Oracle Identity Management 10g components are in a collocated Oracle home. See Section 2.2.3.2, "Oracle Identity Management 10g Components in a Collocated Home".
