Issue:
Applications Manager's master (Automation Engine) intermittently goes into a TROUBLE status. Other behaviors include:
  • Restarting Applications Manager will randomly resolve TROUBLE status
  • Updates to client do not take effect such as activating or deactivating the QUEUES
  • Random performance issues
  • Missing Session ID in RMI Servers Connections window
Cause:
Applications Manager connection to database process 'sleep' and 'wake up' on DMBS Pipes. Pipes are instance-specific, so if CA Automic Applications Manager processes are balanced across multiple instances, then wake-ups issued by one process might not activate the target process.

For example, the master might sleep on one of the RAC nodes, but the wake-up happens on another node and so the master continues to sleep. Processes will wake up eventually, but this is not ideal because of performance.
Resolution:
Refer to DBA to disable any multi-node database configuration such as SCAN RAC or disable active/active or load balancing. Multi-node database configuration should be set in an active/passive for failover only.
