Java Monitor in NWA - Sessions chart

[Former Member]

I'm having trouble understanding the Sessions chart in NWA for the Java Monitor. I would like to know what the InvalidSessionCount key figure is all about. I can understand ActiveSessionsCount and LogoffSessionsCound, but what does InvalidSessionsCount mean. Ours seem to grow rather quickly (much higher than our ActiveSessionsCount) and I need some help understanding what action I need to take (if any).

thanks

Eric,

Basically this monitor shows the number of sessions that have been invalidated and not yet garbage collected. Unfortunately the java applications have no control of the time when the garbage collector will be run - this is decided by the JVM itself, but if the memory occupied by these objects is needed they will be garbage collected. When the memory utilization reaches the MaxHeapSize or MaxPermSize limit, Full GC is triggered

by the JVM which reclaims the memory from the dead objects and the space is freed.

So, as long as you don't experience performance issues you can relax!

Cheers!

Hi Bidwan,

I am experiencing the issues in InvalidSessionsCount parameter in SAP MMC.

It gives message: 221 > 220 Last reported value above threshold.

And I am getting the error while accessing the WAD query through portal.

Please help.

I will open new thread if you wish.
