Can someone explain to me the apparent contradiction in the following two pieces of information ?
From the serialization section of SYS1.MACLIB(IHARB): If the task is not running and the local lock is held, the RB chain will not change. From APAR PQ81630: PQ76702 introduced code for MVSTCB TCB statistics. DFHDSMT calls DFHDSAUT for these statistics in routine CREATE_SNAPSHOT. DFHDSAUT will loop in routine TCB_SCAN due to not serializing the RB chain. A MVS local lock is not enough to serialize the RB chain. Thanks in advance, Mark. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
