Are these jvm args of jvm 1.4 suitable for jvm 5?
1.We used following mem_args with jvm 1.4 and weblogic 8.x. Recently we upgraded to wls 9.2 and jvm 5.x. Please suggest me whether following mem args still suitable with jvm 5 for better performance. If not, advise me required changes for better performance.
USER_MEM_ARGS=" -Xmx512m -Xms512m -XX:+PrintGCTimeStamps -XX:+PrintGCDetails -XX:+PrintHeapAtGC -XX:MaxNewSize=24m -XX:NewSize=24m -XX:SurvivorRatio=128 -XX:-UseParNewGC -XX:+UseConcMarkSweepGC -XX:+CMSPermGenSweepingEnabled -XX:+CMSClassUnloadingEnabled -XX:MaxTenuringThreshold=0 -XX:CMSInitiatingOccupancyFraction=60 -XX:PermSize=128m -XX:MaxPermSize=128m -Xloggc:${WL_DOMAIN}/logs/memory_${SERVER_NAME}.log"
2. I'm new to java tuning concept and I would like to tune the jvm/GC settings in my application running in wls 9.2 and jvm 5. Please let me know how to start with tuning analysis/implementation. What is the best tool for tuning?
Thanks a lot!
