Weblogic Server Out Of Memory Error
8 to BEA 10 . However , we are facing an out of memory issue . Admin websphere out of memory error server is running out of memory after 4-5 days , Though managed server keeps running , eventually application never goes down. Currently we are using following as memory parameters jboss out of memory error WL_JMEM=256 WL_JMEM_MIN=256 WL_ADM_JAVA_XMX=512 WL_ADM_JAVA_MAX_PERM=300 WL_SRV_JAVA_XMX=384 WL_SRV_JAVA_MAX_PERM=192 Can any one throw some light on what is the minimum memory specification required by BEA 10 to support any application. Though I completely agree that the memory specification will differ based on the complexity of application but to support a medium level complex application what should be the memory specification. We

have already tried twice to increase Admin server heap size by changing WL_ADM_JAVA_XMX parameters but sooner or later , Admin server goes down. Any help will be deeply appreciated . Thanks in advance ! Deepak Bala Bartender Posts: 6663 5 I like... posted 5 years ago Can you post the out of memory error that you get ? Also, how did you confirm that changing the parameters actually changed the heap size ?

I would like to thank you for the great work in community We configured memory parameters in WLserver10.var file by defining the variables WL_JMEM Default -Xmx: parameter for Admin and Managed servers WL_JMEM_MIN Default -Xms: parameter for Admin and Managed servers WL_ADM_JAVA_XMX Specific -Xmx: parameter for Admin server WL_ADM_JAVA_MAX_PERM -XX:MaxPermSize for the Admin server WL_SRV_JAVA_XMX Specific -Xmx: parameter for the Managed server(s) WL

Solution: Although it appears that an OutOfMemoryError is thrown this apparent exception is reported by the HotSpot VM code when an allocation from the native heap failed and the native heap may be close to exhaustion. The message indicates the size (in bytes) http://weblogic-wonders.com/weblogic/2010/12/30/different-out-of-memory-issues/ of the request that failed and also indicates what the memory is required for. In some cases the reason will be shown but in most cases the reason will be the name of a source module reporting the allocation failure. If an OutOfMemoryError with this error is thrown it may require using utilities on the operating system to diagnose the issue further. Examples of issues that may not be related to the application are when the operating system is configured with insufficient swap space, or when there is another process on the system that is consuming all memory resources. If neither of these issues is the cause then it is possible that the application is failed due to native leak; for example, application or library code is continuously allocating memory but is not releasing it to the operating system. For more information: http://java.sun.com/j2se/1.5/pdf/jdk50_ts_guide.pdf The recommendation for swap space size in the Solaris is that swap should be configured about 30% of physical RAM.

However it can also be encountered in a recently spawned JVM under the "right" set of conditions. The message is a symptom of an incomplete garbage collection sweep where resources are not properly released upon unload/restart. There is no shortage of debate (Hibernate forum, Sun forum, Spring Framework forum ) regarding which codebase is responsible for this symptom, but the finger of blame has been pointed at CGLIB, Hibernate, Tomcat, and even Sun's JVM. Generally speaking, this is an interoperability issue and can be resolved by changing one of the components in your software stack. Some users have reported relief by upgrading to the latest Tomcat 5.5 release, others have simply opted for another webcontainer implementation (like Jetty or Resin) with varying degrees of success. In my experience, the most pain-free method of resolving this issue is to switch from Sun's JDK implementation to BEA's freely available JRockit implementation. On a recent project utilizing Tomcat 5.5.12 with Hibernate, I was plagued with this PermGen error, at times even experiencing it during web-based unit testing. Since making the switch to JRockit, I have not encountered this issue even once. I attribute the "fix" to the differences between JRockit's and Sun's garbage collection implementations, but have no proof that this is indeed the reason that JRockit resolves the issue. In any case, WFM. Posted by ets ( Jun 23 2006, 11:23:09 AM EDT ) Permalink Comments [41] Comments: I also had these annoying Perm Gen Space OOMs when redeploying webapps.
