While starting the server from eclipse it shows a message that JAVA Memory arguments: -Xms256m -Xmx512m -XX:MaxPermSize=256m. I couldn't understand from where is it taking that value from. After sometime the Weblogic server fails because of out of memory low permgen space. I added startup arguments from console but that doesn't have any effect. Can you help me from where is it taking the memory values from? java weblogic permgen weblogic12c share|improve this question asked Nov 8 '13 at 10:50 Akhil K Nambiar 1,44283065 add a comment| 5 Answers 5 active oldest votes up vote 5 down vote accepted When you configure a "Server" in Eclipse for WebLogic, you select a domain directory (for local). That domain directory contains the startup scripts that Eclipse will use to start the WebLogic Server. These are the same scripts that you would use if you started the server if you did it without Eclipse. Inside the domain directory is a folder called "bin". In the "bin" directory, locate the setDomainEnv file (.sh for unix, or .cmd for Windows). In that file, alter the memory settings to suite your needs. Based on the error message you mentioned in your question, I would increase both the PermSize and MaxPermSize settings to 512m. For PermSize and MaxPermSize, there are two locations each by default in a simple This Site Careers Other all forums Forum: BEA/Weblogic How to troubleshoot a memory leak or an out-of-memory exception in the Weblogic Server Ravi Kiran Va Ranch Hand Posts: 2234 I like... posted 7 years ago Hi Ranchers , Please tell me how to ? How to troubleshoot a memory leak or an out-of-memory exception in the Weblogic Server I know my question is vague . A General idea on this is sufficient . Please help Save India From Corruption - Anna Hazare. Marco Ehrentreich best scout Bartender Posts: 1294 I like... posted 7 years ago Hi Ravi, a log message containing the corresponding OutOfMemoryException would be a good starting point ;-) Additionally you could use a profiler to analyze the memory usage of your application to spot a memory leak in the results. Perhaps you can track down the problem even with simple tools like jconsole or jvisualvm together with the server logs to narrow the part of your application causing the memory leak by watching which actions in the application are consuming so much memory. Marco Ravi Kiran Va Ranch Hand Posts: 2234 I like... posted 7 years ago Thanks Macro , The approach you mentioned(Using Proflers ) would be fine before check in into Repository . Now situation is out of my hand . While Googling i found that "You can also troubleshoot the outofmemory(OOM) or server hanging issues by taking a thread dump of the server. " Can you please tell me what is Thread Stuck mean ? Save India From Corruption - Anna Hazare. Marco Ehrentreich best scout Bartender Posts: 1294 I like... posted 7 years ago Most popular JVMs support startup parameters which enable some kind of heap dump even when the JVM shuts down with an OutOfMemoryException. Then you can try analyze this dump with a profiler later. Moreover at least Sun's JDK comes with additional tools (jmap, jstack, etc.) which allow you to create stack traces and memory dumps from a running JVM. Possibly Websphere gives some support here, too, but I unfortunately don't know very much about it. But to be honest, if you don't know what all these things are it's very unlikely that you will find the necessary information in such a dump. Anyway good luck ;-) Marco Chengwei Lee Ranch Hand Posts: 884 posted 7 years ago Ravi Pavan wrote:The approach you mentioned(Using Proflers ) would be fine before check in into Repository .
