Hi David,

For V5R4 the default classic VM initial heap size ( Xms ) is 16 megs. Default max ( Xmx ) is *NOMAX. For WebSphere, VM initial heap size ( Xms ) is 96 megs. Default max ( Xmx ) is *NOMAX.

I've had too much experience with these settings lately, due to an AS/400 illiterate crowd.

Subject: Default java heap settings?


OK, this may fall in the dumb question category ...

What are the default values for the -Xms (initial heap) and -Xmx (maximum heap) settings?

This is for the V5R4 classic JVM.

Also, does anyone know if it's possible to get the XML formatted output for -verbosegc with the classic JVM?
