JBE Heap Space Issues

0
Harvey Harrison (6●1) | asked Feb 12 '10, 10:32 a.m.
I am having problems with heap space in the JBE when i attempt to run a build for a component where a rather large number of files need to be fetched from the repository. I see the following (abbreviated) sequence when the build begins..

2010-02-12 08:53:15 Yes: Always build a user initiated request.

at com.ibm.team.build.internal.engine.BuildLoop$2.run(BuildLoop.java:466)
at java.lang.Thread.run(Thread.java:619)

The problem occurs a few tens of seconds after the build starts, and no files seem to have been transferred to the build host.

The same JBE will quite happily run a build of a different component with a smaller number of files, so i am guessing here the problem relates to the number of files.

I could not find any obvious configuration parameter that would possibly resolve this. Any suggestions ?

Just wondering here... but, can you try to increase the maximum Heap
Memory used by JBE JVM? Try adding -Xmx1024m (or the number you choose
than can be managed by your architecture - 32 or 64 bits) to:

D:\%JBE_HOME%\buildsystem\buildengine\eclipse\jbe.ini

Hope it helps,

Chemi.
