    ****************************************************************
    APARs PI23083 for DB2 10 for Z/OS and APAR PI30005 for DB2
    11 for Z/OS are new function APARs which made changes to
    IFCID 316 and IFCID 401.  These changes regressed the IFI
    READS support for these IFCIDs.  A variable which affects
    the IFCID formatting was uninitialized.  Depending on the
    residual data in that variable, the IFCIDs can be improperly
    formatted, which can cause errors in tools which consume these
    trace records.
    

Problem conclusion

  • DB2 is changed to properly initialize the variable.
