Error description

  • IIB customers on z/OS migrating from WMB v7, with message flows

    usage in the nodes in which the MRM message tree is first
    parsed.
    

Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    All users of IBM Integration Bus on z/OS parsing MRM messages.
    
    
    Platforms affected:
    z/OS
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    IIB customers on z/OS migrating from WMB v7, with message flows
    that access MRM message trees, might see an increase in CPU
    usage in the nodes in which the MRM message tree is parsed.
    
    Users who parse multiple MRM messages inside a single flow
    invocation are more likely to observe the performance
    difference, especially if they utilise a different set of
    message
    sets on each parse or invocation.
    

Problem conclusion

  • The product has been modified so that the performance costs of
    parsing an MRM message on z/OS are reduced.
