APAR status

  • Closed as program error.

Error description

  • When replacing the SYSTEM.DEFAULT.SUB subscription, for example
    using the "DEFINE SUB(SYSTEM.DEFAULT.SUB) [...] REPLACE" MQSC
    command, without specifying a wildcard schema (WSCEMA) value,
    the WSCHEMA value is set to CHAR. The expected default value for
    the WSCHEMA attribute  is TOPIC.
    

Local fix

  • LOCAL FIX:
    Explicitly specify the WSCHEMA option with the desired value of
    CHAR or TOPIC when replacing the SYSTEM.DEFAULT.SUB.
    

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users who wish to redefine the SYSTEM.DEFAULT.SUB subscription
    object using the REPLACE option.
    
    This includes users restoring queue manager configuration that
    has been dumped by the dmpmqcfg utility.
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    A logic error meant that WSCHEMA(CHAR) was incorrectly used as
    the default when redefining the SYSTEM.DEFAULT.SUB subscription,
    if no explicit value for WSCHEMA was provided.
    

Problem conclusion

  • The MQ queue manager logic has been updated to correctly use
    WSCHEMA(TOPIC) as the default value if no WSCHEMA value is
    providing when redefining the SYSTEM.DEFAULT.SUB subscription.
