Issue/Introduction:

The CA WA Agent 11.4 / 11.5 may spawn processes and show high CPU usage

Cause:

The new 11.4 and 11.5 agent has been changed to spawn additional processes (cybSpawn) to handle large workload. This may result in higher CPU usage.

Environment:

Release : 11.4 / 11.5

Component : CA Workload Automation System Agent

OS : i5 (AS/400)

Resolution:

Change the following parameters so agent doesn't poll for jobs status often and reduce the CPU usage.

os400.job.interval=1000 (default 10 ms)

os400.receiver.threads=10 (default 1)

Note: Job interval is in milliseconds (ms). Suggested value 1000 ms (1 second) or more.

Additional Information:

If there are lots of file monitoring jobs on the agent, then change the following parameters with suggested values.

filemonplugin.sleepperiod=30000
filemonplugin.dispatcher.processors=-1

Note: Sleep period is defined in milliseconds (ms). Suggested value 30 seconds / 30000 ms or more.
