Oracle Identity Manager (OIM) 11g and Oracle Identity Governance (OIG) 12c OIM Managed Server Fails to Start after OS Patching in a Clustered Environment (Doc ID 2793714.1)

Last updated on JULY 17, 2023

Applies to:

Identity Manager - Version 11.1.2.3.0 to 12.2.1.3.220911 [Release 11g to 12c]
Information in this document applies to any platform.

Symptoms

For a Zero Downtime Operating System (OS) patching in a clustered environment with 5 OIM Managed Servers in a cluster, OIM_HOST1 and OIM_HOST4 have been updated with the Oracle Linux (OL) 7patches.  The other 3 nodes have not been patched yet.  During the startup of the OIM_HOST1, the startup fails with the below error:

It looks like JChannel is stuck and waiting for a reply from the coordinator (the other patched node) for a JOIN, and is never receiving it.  The same issue can be seen during the startup of the OIM_HOST4 as well.

The other 3 nodes which were not patched have not been affected.

Changes

Applied patches of Oracle Linux 7 Operating System to 2 of the nodes in the cluster of 5 nodes of OIM.
