Do you run at all before you run out of memory? Have you tried just starting one of the apps at a time and seeing what each seems to do to memory usage? Could it be that one of them has a leak?
I think all the tweaks are really app dependent. You'll have to measure with both a good VM performance monitor and a good java monitor. Our largest app finds gencon garbage collection much more efficient (uses more than 10% less CPU for them). Another found that using Async i/o in WAS exhibited native memory leak symptoms... But other than that, we don't have specific tweeks that we do for every app. Marcy "This message may contain confidential and/or privileged information.

We set swappiness to 0 and started all servers. we will see if that helps and I will look into the sp level upgrade. Does anyone have any good tweeks for z websphere by chance?

Even after that, NTS supports the product line throughout its life. We just can't get Level 3 to look at a problem after 6 months, which means bug fixes won't be created for a customer unless it's against SP1. > > > Mark Post > > ---------------------------------------------------------------------- > For LINUX-390 subscribe / signoff / archive access instructions, > send email to [email protected] with the message: INFO LINUX-390 or visit > http://www.marist.edu/htbin/wlvindex?LINUX-390 > ---------------------------------------------------------------------- > For more information on Linux on System z, visit > http://wiki.linuxvm.org/ > > ---------------------------------------------------------------------- > For LINUX-390 subscribe / signoff / archive access instructions, > send email to [email protected] with the message: INFO LINUX-390 or visit > http://www.marist.edu/htbin/wlvindex?LINUX-390 > ---------------------------------------------------------------------- > For more information on Linux on System z, visit > http://wiki.linuxvm.org/ ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For more information on Linux on System z, visit http://wiki.linuxvm.org/ ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For more information on Linux on System z, visit http://wiki.linuxvm.org/
