How to increase heap size on ncm-as service & powerup.jnlp file?

Environment

NCM 10.1.x

Resolution

To increase the heap-size on ncm-as process on Application Server, execute the following changes:

• Execute: source /etc/voyence.conf
• Take backup of /etc/init.d/ncm-as file for NCM 10.1.6 and below or take backup of $VOYENCE_HOME/bin/service/ncm-as file for NCM 10.1.8 and above.
• Open ncm-as file:
  In CATALINA_OPTS change the -Xms2048m -Xmx4096m values to -Xms4096m -Xmx8192m
• Execute: service vcmaster restart
  Note: Above change will change the heap-size max from default 4GB to 8GB. Make sure the Application Server has 16 GB RAM or more to make above changes.

To increase the heap-size in $VOYENCE_HOME/ncmcore/webapps/voyence/powerup.jnlp file:

• Change below:
  From: initial-heap-size="128m" max-heap-size="512m" 
  To: initial-heap-size="256m" max-heap-size="1024m"
• Execute: service vcmaster restart

 

On NCM Client machine (where GUI is launched):

• Clear the Java cache (steps available at https://knowledge.broadcom.com/external/article?legacyId=382108).
• Download new jnlp from server by accessing https://<NCM_AS_IP>:8880/voyence/powerup.jnlp and launch GUI.
