JES2 Potential Loss of Spool data on z/OS 1.11 and 1.12
PE APAR OA39737 will address the timing window and ensure the initializing member has the most accurate status of the MAS during initialization. In addition, APAR OA38016 will address spool errors caused by the timing window that may result in potential loss of spool data. These types of spool errors are already corrected in z/OS 1.13.
Please see OA39737 and OA38016 for more details or updates.
- If PTF for OA36256 is applied, please avoid putting a spool volume into DRAINING or HALTING state. New volumes can be added or started without exposure.
- If a Spool Drain or Halt must be done, Level 2 can check dumps of JES2 to determine if the spool volume is exposed.
- If OA36256 is applied and a spool volume is already in DRAINING or HALTING state, please remove OA36256 and then (rolling) WARM start each JES2 member.
