APAR status

  • Closed as program error.

Error description

  • If certain configuration file stanzas - such as the Channels
    stanza
    within the qm.ini file - are present more than once in a
    configuration file, the
    contents of the subsequent instances of the stanza are not
    processed by MQ
    

Local fix

  • Ensure each stanza only appears once in the configuration file -
    the
    attributes defined in subsequent occurrences of the stanza
    should be moved to the first occurrence, so that the additional
    occurrence(s) can be removed.
    

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users of MQ using either qm.ini or mqclient.ini files to
    configure MQ behaviour, where any of the following stanzas
    appears more than once in the file:
    
    Channels
    ClientExitPath
    MessageBuffer
    LU62
    NETBIOS
    Security
    SPX
    SSL
    TCP
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    A logic error meant that subsequent occurrences of the stanzas
    listed above were not evaluated when processing configuration
    files.
    

Problem conclusion

  • The configuration file parsing logic has been updated to
    continue to process the configuration file for subsequent
    occurrences of a stanza.
    
    Please note that the use of multiple occurrences of the same
    stanza is not recommended, and any given tuning attribute should
    only appear once within a configuration file, regardless of the
    number of applicable stanzas.
