Issue :

I installed the AdminUI (using embedded JBOss as the Application Server). After login into the Admin UI I get the following error:

Exception during page display:
java.lang.OutOfMemoryError: PermGen space

How can I fix it?

Environment :

AdminUI 12.52SP1

Cause :

The JBoss Server doesn't have enough memory to proceed.


Resolution :

Open the file under siteminder>/adminui/bin directory.
Locate the following line:

  # Java Runtime 
  JAVA_OPTS="$JAVA_OPTS -server"   
  JAVA_OPTS="$JAVA_OPTS -disableassertions"   
  JAVA_OPTS="$JAVA_OPTS -Xms128m -Xmx512m"

Modify the fourth line like this:

  JAVA_OPTS="$JAVA_OPTS -Xms1024m -Xmx1024m"

Then add the following line:

  JAVA_OPTS="$JAVA_OPTS -XX:PermSize=256m -XX:MaxPermSize=256m"

Save the file and restart Admin UI. This will fix the issue.
