TIBCO Business Events – Could not reserve enough space for object heap

Posted on

I just got my hands on TIBCO Business Events for the first time today and trying the Fraud Detection getting started project :P

When trying to start up the engine, I got the following error:

Error occurred during initialization of VM
Could not reserve enough space for object heap
Failed to create the Java VM

After googling for a while, it seems that during the startup, the engine will try to reserve/allocate memory space for the process. and if you have 1 Gb of RAM like I do, most likely you will get the same exception.

C:\Program Files\TIBCO\be\3.0\bin\be-engine.tra

#
# 32 bit JVM parameters for production. Increase heap size and tune other
# parameters as needed.
#
java.extended.properties=-server -Xms1024m -Xmx1024m ............................

So back up your be-engine.tra file and configure the value to a size that will work, for example below:

java.extended.properties=-server -Xms128m -Xmx256m ...........................

Hope this helps ;)
