Local fix
Problem summary
**************************************************************** * USERS AFFECTED: All users of DB2. * **************************************************************** * PROBLEM DESCRIPTION: ABEND0C4 00000038 DSNTFRCV OFFSET09E4 * * DURING LPL RECOVERY * **************************************************************** * RECOMMENDATION: * **************************************************************** 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.
Temporary fix
