The encountered problem was related to the following known problem registered and under investigation by SE :
ONE AUTOMATION INTEGRATION DOES NOT RESET COMMUNICATION
Component: CA Workload Automation AE (AutoSys)
When CA Workload Automation scheduler fails to send events to Automic server
due to some problem, the scheduler will make five reconnection attempts
before disabling the One Automation integration. Pause/Resume services
does not reset the communication between the scheduler and Automic service.
When the scheduler fails to communicate with Automic service, following messages are written to the log:
CAUAJM_E_40388 An error has occurred calling One Automation Event Management
- API Response Code rc=xxx
CAUAJM_E_40379 An unrecoverable error has occurred or the maximum number of allowable errors has been exceeded. One Automation Event Management messaging has been disabled.
Pause/Resume of scheduler does not re-establish the connection.
CA WAAE r11.3.6 SP8 and above
The scheduler does not check OneAutomationEvents to re-establish the One Automation integration.
Release : 11.3.6
Component : CA Workload Automation AE (AutoSys)
Sustaining Engineering works on this problem to get it addressed.
