Issue/Introduction

Users experience that WebUI / WCC is slow and potentially see errors like this in Quick View / Monitoring tab:

Error: E131013 Job not collected in WCC. It could mean some problem with monitoring collector.

Environment

AutoSys Workload Automation

Cause

WebUI Collector is crashing in a loop because it is running out of memory.  $WCC_INSTALL_LOCATION/collectors/WCC_COLLECTOR/log  folder has some files like this too

javacore.20211007.144700.23238.0003.txt

heapdump.20211007.144700.23238.0002.phd

Snap.20211007.144700.23238.0004.trc

 

javacore file above has info like this:

Resolution

• WebUI collector's Java ran out of memory. Increase the memory allocation to WebUI and the Collector Java
  
  
• Our collector memory default settings are below, in /opt/CA/WorkloadAutomationAE/wcc/collectors/WCC_COLLECTOR/conf/wrapper.conf

wrapper.java.initmemory=256
wrapper.java.maxmemory=1024

• Ensure the hosting server has enough memory available and increae the maxmemory settings to higher values.  Example:

wrapper.java.initmemory=1024
wrapper.java.maxmemory=2048

• The same can be done to increase main WebUI's tomcat memory too, via /opt/CA/WorkloadAutomationAE/wcc/tomcat/conf/wrapper.conf

wrapper.java.initmemory=256
wrapper.java.maxmemory=2048

• Bump the above up to a higher value like:

wrapper.java.initmemory=1024
wrapper.java.maxmemory=4096
