Error description

  • Abstract:
    
    After upgrading to Rational Application Developer v7.5.5.4 the
    eclipse.ini references the IBM JVM by loading the jvm.dll
    in-process.  Any attempts to increase the maximum heap size to
    1792m will result in a message 'Failed to create the Java
    Virtual Machine'.
    
    Problem:
    
    This problem only occurs on a 32-bit Windows platform with the
    /3GB switch enabled as described here:
    
    http://msdn.microsoft.com/en-us/windows/hardware/gg487508
    
    Before upgrading the product to v7.5.5.4 the eclipse.ini file
    contained the following:
    -vm ?product install?\jdk\jre\bin\javaw.exe
    and you could set the maximum heap size by modifying the
    following line in this file:
    -Xmx1024m
    to
    -Xmx1792m
    and the product would launch under these conditions.
    
    However, after upgrading to Rational Application Developer to
    v7.5.5.4 the eclipse.ini contains:
    -vm
    C:\Program Files\IBM\SDP\jdk\jre\bin\j9vm\jvm.dll
    
    and any attempts to start the product with a large maximum heap
    size produces the error:
    
    'Failed to create the Java Virtual Machine'.
    
    Local fix:
    
    Open the eclipse.ini file located in the product installation
    directory and change the line:
    -vm
    ?install directory?\jdk\jre\bin\j9vm\jvm.dll
    to:
    -vm
    ?install directory?\jdk\jre\bin\javaw.exe
    

Local fix

Problem summary

  • The product will fail to launch when a large heap size is used
    as a result of launching the JVM using jvm.dll rather than
    javaw.exe.
    

Problem conclusion

  • The product will now launch using the javaw executable.  The fix
    for this APAR is included in Rational Application Developer
    v7.5.5.5 iFix1.
    

Temporary fix
