-Xms5M was the correct format. It was not happy with -xms5M

Hi Mike,

Try using

-xmsXXXXM and -xmxXXXXM load these into the environment variable IBM_JAVA_OPTIONS.
where XXXX is the number of meg required. If you using IT4J the evironment variable changed to this.

I use this to change XXXX to the required JVM size. Good for batch processing.

Regards,
Mark

This environment variable does not appear to work
JVM Arguments
-Djava.class.path=:/JarFiles/ka
-Dos400.gc.heap.size.init=5M

I can't find much documentation on how to enter the value for heap size. When I look at the system if always shows the current size as 4M or 20M or 256M. So I used 5M for the environment variable setting but it still use 4M as the initial size. Does anyone have an example of how this should be formatted?

Thanks

Mike Cunningham
