Re: 32bit JVM on V5R4?

If you mean WebSphere Application Server, the next release of WAS (due out
this summer) will allow you to enable the installed product or a specific
profile in the product to use the 32-bit JVM. Out of the box, the product
will use the "classic" iSeries JDK 5.
Currently available WAS releases cannot use the new 32-bit JVM because they
require JDK levels prior to JDK 5.

I had completely forgotten about this.

A colleague of mine had mentioned it, and said that it should give better
performance as it will use less memory for each object, by virtue of being
32 bit.

Must remember to give it a try. Does anyone know if this is enabled for
websphere?
