Weblogic increase memory
How do I increase the memory used by my Weblogic (Java). 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 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?
Answer
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 WLS installation, one for 32-bit, and another for 64-bit. It won't hurt to change them both. But if you know which JVM architecture you are running, you can change the one that applies to your environment.
