Start java engine failure: how to increase space for object heap


I am trying to install SAP Netweaver 7.0 SP14 SR3 java trail edition but its failing at Phase 30(Starting Java Engine).

I get this message in the log file:

Java process server0 of instance J2E/JC00 [Java: (dispatcher: RUNNING, server0: UNKNOWN)] did not start after 6:00 minutes. Giving up.

In dev_server0 trace file, I could see the following error:

Error occurred during initialization of VM

Could not reserve enough space for object heap

[Thr 1136] JLaunchIAbortJava: abort hook is called

[Thr 1136] **********************************************************************

  • ERROR => The Java VM aborted unexpectedly.

  • Please see SAP Note 943602 , section 'Java VM crashes'

  • for additional information and trouble shooting.


[Thr 1136] JLaunchCloseProgram: good bye (exitcode = -2)

I believe I have to go to the config tool, change the vm settings to increase the initial and maximum heap sizes(Xss, Xmx and Xms) but I don't know how to do it. Can anyone help out?
