Increasing application server memory

When you installed IBM® Rational® Focal Point™, you specified the memory usage limit for the server. You can increase the memory usage for the application server by specifying it with an application server utility or by manually modifying the required files.

Specifying memory by using the Tomcat server utility

To increase the memory in Apache Tomcat server when the services are running, use the server configuration utility:
  1. Open the Apache Tomcat Properties window, and click Java.
  2. On the Java tab, you can increase the values of the Max Perm Size for the Java virtual machine (JVM). You can also increase the memory pool.

Manually modifying the server configuration file

  1. Open the Rational Focal Point application server configuration file.
    • On Windows®: <application server home>/bin/fpenv.bat
    • On Linux®: <application server home>/bin/fpenv.sh
  2. Modify the required values in the configuration file:
    • Allocate more server HEAP memory.
    • Allocate more server PERM memory.
    • Add more flags for optimizing JVM/Server for performance.
  3. Save the configuration file and restart the application server.
