Increasing the web server memory for medium and large clusters

Edit online

Make sure that the IBM Spectrum LSF Application Center server has enough memory assigned. Perform this step on the IBM Spectrum LSF Application Center server that is going to act as the IBM Spectrum LSF Application Center management host.

About this task

The default Platform Application Center configuration works for small clusters. If you have a medium or large cluster, you will need to tune Platform Application Center for optimal performance.

Procedure

  1. As root, log on to the Platform Application Center server.
  2. Set the Platform Application Center environment.
  3. Open $GUI_CONFDIR/jvm.options
  4. Change the jvm memory section to increase the -Xms and -Xmx numbers to a higher number. These numbers are in MB and set the minimum and maximum memory that the loader can use. If you reach the maximum number, Java™ throws an exception.

    For example:

    #define jvm memory
-Xms2048m
-Xmx8192m

    For large clusters, define the maximum memory to at least 8 GB.
