jlaunch memory leak


I m using Netweaver AS with Oracle Database 10g Enterprise Edition. Recently i have observed that the jlaunch.exe is consuming lots of system memory and keeps on growing until we force a restart of the AS. The gc parameters are as reccommended in SAP notes. Can any body help please??

JLaunch process is a wrap of the java process within SAP J2EE cluster. it could be one of your server node in your case. you can find more information about jlaunch at:


it's depending on your JVM configuration, the process could use memory up to the total of maximum heap size + Maximum perm space + native/java stack size.

if you follow SAP recommendation for the initial setup, normally one server node process could use up to around 2.3GB memory.

So it might be a configuration rather than memory leak.

If you still think it's suspected memory leaking issue,you should start with GC analysis, find a good GC graphic viewer or using Wily introscope will help you a lot.
