After Fail Over to the Second Node of OracleAS Cold Failover Cluster OPMN Fails to Start (Doc ID 420389.1)

Last updated on JUNE 01, 2023

Applies to:

Oracle Fusion Middleware - Version to [Release 9iAS to AS10gR2]
Information in this document applies to any platform.


This note addresses the following High Availability (HA) setup:

When the AS Infrastructure is failed over to Node 1, everything works fine.

When the AS Infrastructure is failed over to Node 2 it is not possible to start the opmn daemon, and therefore any of the opmn-managed processes in one of the oracle homes on Node 2.

The following error is reported to the command line:

Communication error with the OPMN server local port.
Check the OPMN log files

The requirement is to be able to fail over the AS Infrastructure to either node of the CFC and start all of the opmn-managed components in both the Infrastructure and Middle Tier homes.
