RPT: Java heap error at schedule run

Technote (troubleshooting)


Attempts to run an IBM Rational Performance Tester (RPT) schedule result in error Test run stopped due to error.


The 12 hour run stopped after 3 hour.
At the time that the schedule stopped, the RPT heap uses 242Mb out of 248 Mb.


The JVM heap size is too small.

Resolving the problem

Change the JVM heap size to 1500 Mb.

  1. Open eclips.ini in the SDP folder.

  2. Change the value of -Xmx to 1500. Add if the entry is not there. Now the configuration file reads -Xmx1500.

  3. Save and close eclipse.ini

Alternatively, you can start RPT from the command line with -Xmx1500. For example,

"C:\Program Files (x86)\IBM\SDP\eclipse.exe" -product -Xmx1500
