  • Closed as program error.

Error description

  • Adding JVM specific arguments to either PREFIX or SUFFIX in the
    Performance Tuning Wizard results in truncated or corrupted
    entry in Windows registry. The setup files must not truncate the
    "Equals" sign when entering the parameter in the UI.
    For example:
    #JVM Arguments suffix
    JVM_ARGS_SUFFIX=
    
    #JVM Arguments PREFIX
    JVM_ARGS_PREFIX=
    
    #JVM Arguments suffix Container
    JVM_ARGS_SUFFIX_CONTAINER=
    
    #JVM Arguments suffix Container
    JVM_ARGS_SUFFIX_CONTAINER=
    
    #JVM Arguments PREFIX Container
    JVM_ARGS_PREFIX_CONTAINER=
    
    There are many flags according to the IBM
    JVM Diagnostic guide that require an "="
    http://www.ibm.com/developerworks/java/jdk/docs.html
    

Local fix

  • Workaround:
    1. Add the entire argument with the "EQUALS" sign
    into the UI.
    2. Save the Performance Wizard.
    3. Stop the system.
    4. Run the setup files.
    5. Use 'grep' or search the properties directory for the
    argument leading up the "EQUALS" sign.
    6. Add the remaining arguments including the "EQUALS"
    sign into the various files.
