ADMU3011E: Server launched but failed initialization when set generic VM args

I was facing a Java.lang.OutOfMemoryError: Java heap space in the Websphere console.

To resolve that I have put the following generic VM args

-Xms512m –Xmx1024m -XX:PermSize=512m -XX:MaxPermSize=512m

But after that I cannot start the server, it is showing

ADMU3011E: Server launched but failed initialization.

I cannot open the WAS Admin Console to revert the chnages back. What can I do in this case?

Solution

  • Referring to the valuable comments, I came to the following solution:

    Go to ${PROFILE_HOME}/config/cells/${CELL}/nodes/${NODE}/servers/${SERVER} and modify server.xml

    Removed generic JVM arguments
    -Xms512m –Xmx1024m -XX:PermSize=512m -XX:MaxPermSize=512m

    Then started the server again.
