Local fix
n/a
Problem summary
**************************************************************** * USERS AFFECTED: All DB2 11 for z/OS users of MODIFY RECOVERY * * utility. * **************************************************************** * PROBLEM DESCRIPTION: An endless loop occurred in DSNUBCOP * * while MODIFY RECOVERY utility was * * running. * **************************************************************** * RECOMMENDATION: Apply corrective PTF when available. * **************************************************************** When MODIFY RECOVERY is running, an endless loop might occur. This problem occurred due to incorrect COMMIT handling logic. As MODIFY RECOVERY was running, position on SYSLGRNX was not maintained correctly after a COMMIT, causing the same rows to be read repeatedly.
Problem conclusion
MODIFY RECOVERY utility code was changed to correctly maintain position on SYSLGRNX during COMMIT processing, thereby preventing the loop.
