Recommended max heap size on WebSphere (64-bit)?
Hi All,
I know that the minimum recommended max heap size for RTC 2.0 is 1536MB. I also believe that the general consensus is that anything bigger than 4GB isn't good either. If we have enough available memory is there any reason we shouldn't be at 4GB? For reference - what does jazz.net run on?

In answer to what jazz.net runs on - take a look at one of the dashboards:
http://jazz.net/jazz/web/projects/Rational%20Team%20Concert#action=com.ibm.team.dashboard.viewDashboard
It looks like we are running on 1499 Mb, of 2048 Mb max.

Ahh - there are so many things to know - I've been seeing our customized dashboards for so long I forgot this widget existed and was available on jazz.net.
Thanks!
"So many thing things to know" (and one place to go - the forums on jazz.net). Start of a song perhaps, hmm - maybe not :-)

Yes - RTC on 64 bit WAS should use
100 for initial and
4096 for max heap. (Assuming you have more than 4 GB for you OS)
This is because Java(currently) on 64 bit can handle up to 4 GB of memory.
