Side question: How can I switch On/Off CA reclaim?
Is it some DC parameter or IDCAMS DEF CL one?
At the data set level, you can use RECLAIMCA and NORECLAIMCA on ALTER
and DEFINE. At the system level, you can use CA_RECLAIM in IGGCATxx to
turn it
1) master enablement in IGDSMS00 (CA_RECLAIM(DATACLAS))
2) Application to individual dataclas via the dataclas definition
(CA-RECLAIM=YES)
And then recreate the dataset,,,

No need to recreate the data set. Just use:
ALTER entryname
Thanks for the update I was not aware of that.

No need to recreate the data set. Just use:
ALTER entryname RECLAIMCA|NORECLAIMCA
...to change it.

Hi, I agree that it just sounds like your CDSes have just grown and need more
space. Please note that the CA Reclaim function became available in V1R12.
When CA Reclaim is enabled for the CDSes, it minimizes the need to reorganize
the CDSes, especially after running EXPIREBV. When a VSAM
it on?

Yes. For the exact problem you are currently encountering!

CA Reclaim is a new feature I had not noticed. Since it is turned off by
default, I now need to ask:
Is there any reason not to turn it on?

There might be some slight performance impact, and also check for any

I am not a VSAM expert, and I didn't stay in a hotel of any
I can think of no reason not to turn it on.
I have had it turned it for *all* VSAM processing (including user catalogs)
since early 2012 w/no reported issues.
I would turn it on prior to rebuilding the CDS's/UCATS and then proceed with
whatever is necessary.
HTH,

I asked for reasons to
CA_RECLAIM() parm on IGDSMSxx
check this out:
How much data actually expires when you run EXPIREBV?
AFAIK, the is no change to dfHSM that would account for this behavior.
It sounds like the dataset is just getting full and needs to be expanded.
Remember the 4gb limit for non-SMS VSAM.

Since moving to z/OS 1.13, my DFHSM BCDS seems to
