Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    IBM i users who utilize the WRKMQMCONN command to filter
    connections
    
    
    Platforms affected:
    IBM iSeries
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    Using the WRKMQMCONN with a filter of *CONNAME may result in an
    FDC in xcsFreeMem. Additionally, using WRKMQMCONN with any
    filter may not return the correct output.
    

Problem conclusion

  • IBM MQ code has been modified to prevent an FDC from being
    generated when using filter *CONNAME and also to return
    appropriate results when filters are used.
