APAR status

  • Closed as program error.

Error description

  • The system volume of the IBM MQ Appliance fills.  As a result of
    this,
    services which rely on this volume may fail.  For example, when
    starting
    the Web UI console, you may encounter this error message:
    
    "The IBM MQ Appliance Web UI server is starting
    JVMSHRC561E Failed to initialize the shared classes cache, there
    is not
    enough space in the file system. Available free disk
    space bytes = 0, requested bytes = 62914560.
    
    JVMSHRC686I Failed to startup shared class cache. Continue
    without using
    it as -Xshareclasses:nonfatal is specified
    
    Starting server defaultServer.
    
    Server defaultServer start failed. Check server logs for
    details.
    Failed to start the IBM MQ Appliance Web UI server"
    
    The mqcli 'status' command shows that the "System" volume is
    100% in use,
    for example:
    
    System volume:                           14983MB used, 14.7GB
    allocated [100%]
    

Local fix

  • The only local workaround is to manually delete the file that
    has filled the system volume or move to a firmware that contains
    the APAR fix.
    
    It is not possible to delete the file from the Appliance command
    line and so you must contact IBM Support who will be able to
    assist you further.
    

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users of the High Availability functionality of the IBM MQ
    Appliance may be affected by this issue
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    A log file used by the High Availability functionality of the
    IBM MQ Appliance was allowed to grow indefinitely until it
    filled the system volume.
    

Problem conclusion

  • Log rotation has been enabled for the file so that it can no
    longer grow large enough to fill the volume.
