    ****************************************************************
    During LPL / GRECP recovery if csect DSNIBMOC is invoked, it may
    not always free the Program Recovery routine Entry (PRE). This
    results in an orphan chained PRE and any subsequent 04E abend
    seen during log apply (or later) may result in a program
    exception ( ABEND0C4 ) in DSNTFRCV because of the orphaned PRE
    Also, a loop condition is possible in DSNTFRCV, but since the
    secondary DSNTFRCV ABENDS0C4 occurred in the Functional Recovery
    Routine (FRR), then DB2 will abnormally terminate.
    

Problem conclusion

  • DB2 LPL/GRECP log apply logic is modified so that each csect
    makes sure that it removes the Program Recovery Entry from the
    stack.
