Error description

  • Error Message: JVMJ9GC063E Unable to open file
    'c:\directory\gc.log' for writing
    JVMJ9VM015W Initialization error for library j9vrb24(3): Failed
    to initialize
    Could not create the Java virtual machine.
    .
    Stack Trace: N/A
    .
    When the filename given to -Xverbosegclog fails to be created,
    the VM fails to initialize and does not failover to STDERR as
    per the Diagnostics Guide
    

Local fix

  • Ensure that the full path given to -Xverbosegclog exists and can
    be written to by the JVM.
    

Problem summary

  • The problem is caused due to the verbose logging not attempting
    to create the directories for the GC log or failing over to
    STDERR
    

Problem conclusion

  • This defect will be fixed in:
    6.0.0 SR10
    5.0.0 SR12 FP5
    .
    The JVM has been updated to attempt creation of the missing
    directory structure and if this fails it will place the verbose
    GC output or logging to standard error (stderr)
    .
    To obtain the fix:
    Install build 20110418 or later
    

Temporary fix
