To return expected results, you can:

  • Reduce the number of search terms. Each term you use focuses the search further.
  • Check your spelling. A single misspelled or incorrectly typed term can change your result.
  • Try substituting synonyms for your original terms. For example, instead of searching for "java classes", try "java training"
  • Did you search for an IBM acquired or sold product ? If so, follow the appropriate link below to find the content you need.

  • Resolving The Problem

    To avoid this error, follow these steps to set the JVM max perm size limit:

  • From the WebSphere Application Server Administration Console, select Servers > Server Types > WebSphere Application Servers > <Server running WBE> > Server Infrastructure > Java and Process Management > Process Definition > Java Virtual Machine > Generic JVM arguments.
  • Add -XX:MaxPermSize=1024M to the generic JVM argument to set the max perm size.
  • Restart the application server.
  • After tuning the heap sizes, monitor the system to make sure that paging does not occur.
