Symptoms

Strange characters appear in both the dm_oracle log and pinlog in a RAC DB setup with FAN configuration. The FAN  failovers themselves seem to work fine but the strange characters appear in the logs which is not expected.

Scenario:

1. BRM 7.4 on Linux with MPS1 + patch 14519085 configured using multi-schema
2. DB using RAC and DB service with FAN enabled
3. DB service configured in dm_oracle pin.conf (sm_svcname)
4. Perform shutdown/abort on one instance
5. Check DM log and pinlog for strange characters

(also notice that service should failover to backup instance and FAN notification should logged in dm_oracle log)
