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.
