    ****************************************************************
    Abend is due to a serialization issue on a pageset/partition
    read-lsn chain, when a read-lsn is being registered for a
    scrollable cursor.  Since the scrollable cursor logic is using
    a different latch to serialize the chain than the other code
    which manipulates the chain, it may run into an ABEND0C4 due
    to the chain changing underneath it.
    

Problem conclusion

  • DSNB1RLS has been modified to use the correct latch to serialize
    the read-lsn chain.
