PCMD and ActiveMQ, "Failed to subscribe to topic pcmd"

Troubleshooting


Problem

How do I resolve the error, "Failed to subscribe to topic pcmd"?

Symptom

Example error message:

Feb 01 16:09:50 2018 ERROR [main] pcmd - Failed to subscribe to topic pcmd due to: Durable consumer is in use for client: pcmd_hn1_1099 and subscriptionName: LogMgr
Feb 01 16:09:50 2018 ERROR [main] pcmd -
......

Cause

This issue happens when the pcmd service starts and connects to ActiveMQ. This is an ActiveMQ problem, not a PCMD problem.

Resolving The Problem

To resolve this issue, restarting ActiveMQ alone does not resolve the issue.

Resolution procedure:

1. If HA is enabled, change HA failover mode to manual

#pcmhatool failmode -m manual


2. Stop the ACTIVEMQ service and PCMD service
#pcmadmin service stop --service PCMD
#pcmadmin service stop --service ACTIVEMQ

3. Backup and then delete the below file
/opt/pcm/activemq/data/kahadb/db.data

4. Start the ACTIVEMQ service and PCMD service
#pcmadmin service start --service ACTIVEMQ
#pcmadmin service start --service PCMD

5. Check hpc service status
#pcmhatool check

6. Change HA failover mode back to auto (optional)

#pcmhatool failmode -m auto
