    ****************************************************************
    An ABEND04E RC00C90101 at DSNIBMCL5001 can occur when accessing
    LOB with READ ONLY (ACCESS=RO) and SPRMSHP is set to 1.
    The reason for the abend is that Db2 has failed to use the
    correct scheme to calculate the data set (piece) where LOB
    object of interest resides. As a result, the incorrect data set
    (piece) is used for an open request, which then renders the
    reported abend.
    

Problem conclusion

  • Db2 is modified to use the correct scheme to calculate the
    right data set (piece) for open request.
