OPMN and WebLogic AdminServer Port Conflicts When Configuring PFRD and IDM (OID) 11g on Same Host Machine (Doc ID 1133653.1)

Last updated on JUNE 29, 2023

Applies to:

Oracle Fusion Middleware - Version to [Release Oracle11g]
Information in this document applies to any platform.


Example Scenario:

Portal/Forms/Reports/Discoverer (PFRD) 11g and Oracle Identity Management (OID/DIP) 11g have been configured on the same machine.

Important to Note:

Installing PFRD and IDM in the same MIDDLEWARE_HOME (MW_HOME) is not recommended. This is stated in the Release Notes located in the Documentation Library e.g.

Oracle Fusion Middleware Release Notes 11g Release 1 (11.1.1) for Linux x86
2.2.1 Installing Oracle SOA Suite and Oracle Portal, Forms, Reports and Discoverer in the Same Middleware Home

Co-location is not recommended for the following reasons:
  • patchset version and WebLogic Server version compatibility
  • the patching story for PFRD being out of sync with other Fusion Middleware products.
For example, PFRD does not work against WebLogic Server 10.3.5, and therefore patchset cannot be applied to PFRD. For PFRD to work, the WebLogic Server must remain at a version (e.g 10.3.4) which is compatible with a patchset level (e.g. supported by PFRD. Application of a later patchset (e.g. would require WebLogic Server to be patched too.

This means that other products, such as IDM, cannot consume a later patchset (e.g. if they reside in the same MW_HOME as PFRD. Why? Because the patchset level is restricted by the WebLogic Server version required by PFRD.

PFRD and IDM 11g solutions can reside on the same machine, but they must be built in separate Middleware Homes. If two Middleware Homes on the same machine are used, the issue discussed in this support document may be seen as port conflicts arise at an operating system level.

At configuration time, the 'Auto Port' option was chosen in the Configuration Assistant.

Post configuration an attempt is made to start up the two configurations - (Portal/Forms/Reports/Discoverer and Identity Management (OID/DIP) concurrently. All components in the first configuration (e.g PFRD) start up fine. The components in the second configuration do not start successfully e.g
