Migrating from Sun jdk to JRockit jdk

Reddy-OracleSep 1 2008 — edited Nov 13 2008

Hi All,

We are currently running oracle communicator and Mobility server Scenarios. Previously we did the runs by using Sun jdk 1.5 and 1.6, and now we are doing same runs by using JRockit1.5_10
and JRockit1.6_05.And we are observing regression in our JRockit runs compared with Sun Jdk in both 1.5 and 1.6.

Sun Jdk JVM parameters:
Xloggc:/scratch/ocmsuser/gclogs/ocms_gc.log -XX:MaxPermSize=128m -XX:NewRatio=3 -XX:+UseConcMarkSweepGC -XX:+UseParNewGC -XX:PermSize=128m -Xss128k -Xms1280M -Xmx1280M.

equivalent JRockit Parameters used:
-Xverbose:gc -Xverboselog:/scratch/ocmsuser/gclogs/sip_gc.log -Xmx1280m -Xms1280m -Xgc:gencon -XXnosystemgc -XXnocompaction -Xns40m -XXtlasize:min=3k -XXkeeparearatio=0

Our question is are we using same exact JVM parameters in JRockit compared with Sun jdk?

Thanks&Regards
Srinivas Reddy
