Re: RMM CDS utilization vs 3.4 utilization
Wayne, I am not sure you understood what I said about REPRO use of dss to copy/move/backup the cds does nothing to consolidate the space within the CDS (KSDS) Mike Wood -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
Re: RMM CDS utilization vs 3.4 utilization
Mike, I really appreciate your response. I am someone that was asked to oversee RMM and am not completely familiar with the workings of RMM and with that said I would like to see an example supplied and discussed in the I C manual under the chapter titled Monitoring the Space Used by the Control Data Set to run jcl like the one supplied in the Moving the Control Data Set that uses the Backup(DSS) example to copy the cds to a new cds. Your example could include a Backup(DSS) step and a then a step to RENAMEU the old cds to a new cds name then discuss the HURBA/HARBA * 100 calculation to show the programmer the percentage of free space actually inside the working cds. We do not regularly reorganize our CDS but we are I the process of moving it and found out that we are only using 25% of 41000 tracks (in 5 extents) in our working CDS. That is a lot of wasted space that I did not find out about until I HAD to move our CDS. This will all be a moot point once we turn on CA RECLAIM. Sorry for the rant.

They were written based on lots of experience with many different installation. The CDS utilization is simply HURBA/HARBA * 100 It makes no account for empty space in CIs or CAs, nor for the potential to grow the CDS into multiple extents. To determine really what space is actually used, you could define a VSAM KSDS like the CDS and repro the records from the CDS to the new KSDS and see what the HURBA/HARBA is then.
