EP6 SP4(NW04) and maximum heap size

[Former Member]

Is there a limit to maximum heap size. I know for EP6 SP2 the limit was 1536 mb.

Hi Prakash,

Depends on what you are running on the WAS 6.40 and your total memory on platform(s). You can check notes 723909, 807899. The latter note is for Java settings for XI 3.0 on J2EE 6.30/ 6.40.

First, the tuning guide suggests to start with 1024 and increase when you feel performance is suffering - and also do some validation that the larger heap is usefull.

Second, the paradigm has shifted from SP2 - as long as you have CPU capacity it is better to add more server processes with samller heaps. The old 1.5 CPUs / server still holds.

Third, the limit depends on your OS, ~ 2GB+ for 64 bit architectures.
