Re: JAVA USED 95% OF THE GC HEAP.

Rob, I believe it has to do with how your java programs were compiled and
how they are running using the runjva command. Take a look at the GO
CMDJVA commands.

I'm a real newbie on this stuff. We had a consultant come in and install
Infor's WebTop and related. It uses this.

I tried selecting "Web Performance Advisor". Ran for quite awhile but
nothing appears in pane.

Where do I check the stuff you mentioned?

The server can become overwhelmed by the garbage collection and all but
become unresponsive. Check and see how often garbage collection is
running. If it is more than several times an hour than you may need to
increase the size of the heap. 262144 seems really small to me for any
server with applications actually running.

I found this which states the message may occur but no clue as to

whether

to be concerned about it, or what actions to take.
