According to the fine manual, if CA-Reclaim is enabled globally (in IGDSMS00), you can alter the cluster to enable CA-Reclaim;
>From AMS Commands( Rel 2.1) SC23-6846-01: <quote> RECLAIMCA|NORECLAIMCA Specifies the CA reclaim attribute of a key-sequence data set (KSDS). RECLAIMCA Specifies that the DASD space for empty control areas (CAs) will be reclaimed so that it can reused for that KSDS. CA reclaim cannot reclaim space for: v Partially empty CAs v Empty CAs that already existed when CA reclaim was enabled v CAs with RBA 0 v CAs with the highest key of the KSDS v Data sets processed with GSR. NORECLAIMCA Specifies that the DASD space for empty control areas (CAs) will not be reclaimed. You can disable CA reclaim at the system level with the IGDSMSxx member of PARMLIB or with the SETSMS command. This does not change CA reclaim attributes in the catalog. For more information, see the topic about reclaiming CA space in z/OS DFSMS Using Data Sets. </quote> HTH, ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
