Hi All,

Can someone please help in analysis of the GC logs of WAS 7 (64 Bit) on Solaris (System Configuration: Sun Microsystems sun4v SPARC Enterprise T5120 & Memory size: 65408 Megabytes).

The application seems to be having a unusual large GC.

Can someone provide any hits at where i can start looking at tuning the GC.

The application is a JSF (WAS 7 - JSF 1.2) application. The application was working really well in WAS 6.1 (JSF 1.1)

mx - Min Heap Size 2300
ms - Max Heap Size 2300
PermSize 512
MaxPermSize 512
MaxNewSize - -XX:MaxNewSize 1000
NewSize --XX:NewSize 1000

We have observed the following in the GC. can this impact the performance ? what are the time specified in like user , sys and real ?

CMS: abort preclean due to time 77664.614: CMS-concurrent-abortable-preclean: 8.588/8.588 secs Times: user=8.65 sys=0.15, real=8.59 secs
