If you're using the ATTACH, I don't really know why it isn't releasing the storage. But, if you want to try, you can do FREEMAIN the entire 236 and 237 subpools. But I don't know what impact this might have on other system programs which might use those subpools. Example would be: FREEMAIN RU,SP=236 FREEMAIN RU,SP=237
>From reading here: http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/IEA2V2A1/1.8.3 This may not be advisable because these contain the SWA for the job. In note 12, it says: <quote> 12. Virtual storage is located within the scheduler work area (SWA). The storage is freed at the end of the started task or at initiator termination for subpool 236 and at the end of the job for subpool 237. The NSHSPL and NSHSPV parameters on the ATTACH or ATTACHX macro invocation used to create the currently active task determine ownership of the subpool. If the currently active task was given ownership of the subpool, then the TCB of the currently active task owns the storage in this subpool. If the currently active task is sharing this subpool with the attaching task, then the TCB of the attaching task owns the storage in this subpool. For more information, see the description of the ATTACH and ATTACHX macros in z/OS MVS Programming: Authorized Assembler Services Reference ALE-DYN and the virtual storage management topic in z/OS MVS Programming: Assembler Services Guide. For additional information about the SWA, see z/OS MVS Initialization and Tuning Guide. </quote> Seems to me that if you ATTACH the interpreter for each use, the subpools should have been freed. You may have found a bug in z/OS. -- John McKown Systems Engineer IV IT Administrative Services Group HealthMarkets(r) 9151 Boulevard 26 * N.
