Recommended Tomcat's Java Heap Size to Server HPSM9.41 webtier

Question

Our company uses HP Service Manager 9.41 to manage ticketing, The web application(called webtier) is hosted in Apache Tomcat, the issue we are facing is running into performance issues with a high CPU load, I wonder if this could be related into Java Heap Size as the initial and the maximum memory pool is set into 1024MB currently in a server with 12GB of RAM.

So my question is, is there in recommendations about the Value of the Java Heap Size?

Answer 1

I went back to answer my question, may be others will face the same issue.

Thanks to @Eugène Abdell for his comments, that helped me to reach the solution.

I set up Tomcat heap size(memory pool size) into 512MB for Initial memory pool and 2048MB for the maximum memory pool(Micro Focus support adviced me to use a miximum heap size that is between 1.5GB and 2GB), and HP Service Manager Web server seems to work fine.

I hope this will help others that gets into the same issue.
