    * PROBLEM DESCRIPTION: ABEND0C4 in DSNB1RLS or DSNB1DCM.       *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    Abends are due to a residual PBA0 control block being left on
    the read-lsn chain for a scrollable cursor.  If the read-lsn is
    registered with no read claim held - or if it is registered for
    a partition when the agent holds a tablespace-level drain - the
    block will not be found at commit time and removed from the
    chain.  Once the block has been freed and reused, its presense
    on the read-lsn chain can result in an ABEND0C4 in DSNB1DCM or
    DSNB1RLS.
    

Problem conclusion

  • The read-lsn registration code has been modified to ensure
    that the PBA0 block is correctly chained.
