After Replication, OC4J not coming up
Problem Description: We have two environment, Main production instance and Disaster Recovery instance. The environment has OAS and Oracle Access Manager Products installed in same serversOC4J service not coming up in DR nodes after DB replication from production to DR.
Cause: Actually we faced some issues in production nodes and we have replaced the old back, after we reset the IASpassowrd in production instance. The password will be stored in DB(encrypted format ) as well in ias.properties file. Whenever you try to bring the OC4J service, it will compare the IASpassword value in ias.properties file and in OID. If it not matches, OC4J service will not come up.
During Drill, we faced some issues in DR instance, our OC4J services unable to came up in node 2.
Problem: IASpassword is mismatch.
Workaround summary,
1. Stop all the osinfra services.
2. If osinfra services unable to bring down, please execute the following steps
ps –ef | grep opmn
Kill all the process
ps –ef | grep oid
Kill all the process
3. login into oid and truncate the ods_process table.
