Based on info from John Eells, I would say. "it depends". Reading the info APAR II14640 (thanks for the reference John), I find:
<quote> Depending on the age of VSAM data sets, you may have some data sets that are not eligible for CA RECLAIM show a value on a listcat of CA-RECLAIM(YES). Data sets created prior to the installation of the PTF for OA26256 on z/OS 1.10, or data sets created on z/OS 1.9 or earlier releases may show a value of CA-RECLAIM(YES) for ESDS, RRDS, LINEAR VRRDS data sets. Installation of the PTFs for apar OA36052 will correct the listcat output. </quote> And: <quote> There is a tool available that will produce a one line listing of data sets that are currently eligible for CA RECLAIM. While you can run an IDCAMS LISTCAT LEVEL or LISTCAT CATALOG to get a list of data sets, either of these will also produce a large amount of output and also list data sets that are not eligible for CA RECLAIM. This tool can be downloaded from the following FTP site: ftp://public.dhe.ibm.com/servers/storage/support/software/dfsms/ It is on this site as CARECLAM.JCL.CNTL.TRSD. It will need to be downloaded in binary mode to a data set with the following DCB attributes: LRECL=1024,RECFM=FB,BLKSIZE=6144,DSORG=PS . After downloading it will need to be untersed using AMATERSE. Note that when untersing the output data set will be a PDS, so you need to supply directory blocks for the output data set when untersing. A space allocation of (TRK,(1,1,6)) should be fine. If you have questions or concerns about this tool open an ETR to component 5695DF106. </quote> Of course, to be absolutely sure, you could rebuild the dataset. <snip> I'm not sure if I got my original question answered. We've enabled CA-Reclaim on the dataset, but I what I wanted to know does a repro back into the original dataset using the replace and reuse options, enable CA-Reclaim on all CA's, or do I need to reallocate the dataset?
