Expiration date
Hello, Does anybody know as to what takes precedence under SMS, either an expiration date(on a disk dataset) or expire non-usage on a management class? We have some files that have an expiration date but the management class has a much longer expire non-usage date and just wondering which date is honored by the system.

Re: Management classes and expiration dates revisited
Hello, I just ran into this on my jcl manual, it's a few years old but I imagine still holds true: With SMS, both the expiration date specified on EXPDT and defined in the data class for an SMS-managed data set can be limited by a maximum expiration date defined in the management class for the data set. I interpret this as, the 'expire non-usage' on a management class is the maximum period that a file will be kept, but if an EXPDT or RETPD is specified without exceeding the retention on a mgmt class, it will honor the EXPDT or RETPD. -Original Message- From: IBM Mainframe Discussion List [mailto:IBM-MAIN@bama.ua.edu] On Behalf Of Starr, Alan Sent: Tuesday, December 06, 2011 2:24 PM To: IBM-MAIN@bama.ua.edu Subject: Management classes and expiration dates revisited Back in October, a question was asked about the DF/SMS management class expiration attributes fields. To me, both the ISMF help screen and the manual (DFSMShsm Storage Administration - Specifying expiration attributes in chapter 2) indicate that BOTH expire after days non-usage AND expire after date/days, when specified, must be satisfied. John Gilmore did some testing and determined that, when both fields specify something other than NOLIMIT, the EARLIEST date appears to takes precedence. Here is his text: Five pairs of data sets--different DSORGs, which proved to be irrelevant--were used EXPIRE NON-USAGE 5 EXPIRE DAYS/DATE 5 was specified for both datasets in each pair. The first, call it A, was opened at 1700 on four successive days. The second, B, went unopened. Both A and B expired after five days. Last week, someone asked if these management class fields takes precedence over the EXPDT saved in a dataset's DSCB. A responder specified Management Class overrides expdt in the vtoc, which differs from my experience and this text I found in the aforementioned DFSMShsm manual: The expiration attributes, EXPIRE AFTER DAYS NON-USAGE and EXPIRE AFTER DATE/DAYS, govern how long a data set associated with the management class is kept if no expiration date is listed in the data set VTOC entry or if the VTOC entry contains an INVALID EXPIRATION DATE. I was wondering if any of you have discovered situations in which the MC fields override the DSCB EXPDT? Which elements, features or products operate this way?

Re: DFHSM QUESTION : Allocation/migration Threshold
Well, if there is no migration then adjusting the thresholds will not get you much. The only space that will be released will be from those files that are over-allocated or expired. In this case, then you have to look at the files to make sure that you have no un-cataloged files, these will take up space but will never go away. Also, if you have GDGs with an expiration date, these may stay around even though they are not in the base and this is governed by the rolled off gds action attribute in the management class; In other words, you have to get to know the data much better to determine if there is space that should be released. Another way to release space on a file is by the use of partial release attribute on the management class. Also, files that are Fixed instead of fixed-blocked will waste quite a bit of space.

Re: 3390s on SAN?
Well, you have to move out enough data to cover the number of TB that you're reconfiguring. For the most part, the Rank/array has to have enough contiguous data to carve out the volumes. In other words, if you want to carve out 1 TB of mod-9 volumes, then you have to have 1 tb of contiguous free space on the rank. As for ease to get this done, that depends on the level of microcode that's on your box. I know that currently, some very large volumes can be created but I don't know how this relates to the amount of space on a rank.

Re: MCDS Dataset Help
If you're going to use the RECONNECT parm, which is part of FSM(Fast Subsequent Migration) then you need to make sure that you have these set accordingly: MIGRATIONCLEANUPDAYS(#1 #2 #3) we have ours set at (5 14 5) These are the parms that determine how long, in # of days, the MCDS records are kept. Thus, when a person recalls from a file from ML2, the migration record will be kept for x number of days; when this same dataset is migrated and WAS not updated then said file will not be re-copied; the only thing that gets updated is the pointers going back to the same tape where it was before(provided the tape has not been recycled).

Re: System Dumps and SMS allocation fails
When allocating files via SMS, the SMS attributes then either have to be explicitly assigned or allowed to be assigned. You mention that the DC is one that is not listed in the parmlib and the volume is a non-sms volume; thus, check your ACS routines for the SMS allocation of these files.

We are trying to convert to using SMS managed volumes for our system dumps since we need the LARGE attribute for our large DB2 dumps. But something is preventing the dumps from allocation when MVS tries to make the allocation. What? HELP! I can make the allocation find from 3.2 or even IEFBR14 in batch. Correct volumes correct size - all is well, but MVS still fails when it tries. (using just the dataclas, storclas and mgmtclas in the allocation) SMS volumes are 2 empty mod-9 (other than VTOC, VTOCIX and VVDS).with largest free space as 9,993 cylinders on each one. Here are the messages we receive when a dump occurs. All standard messages, other than I cannot explain the DO NOT HAVE SUFFICIENT SPACE message. Plus the messages after that are odd! The IEF196I IGD100I message. The address D913 is for volume SYX5D1 (one of the non SMS volumes). The dataclass is also not the one in parmlib.

Re: User datasets wrongly catalogued under Master Catalogue
Yes, it is possible to move files cataloged to the master onto an alias under a user catalog. It's been a while since I've done this but you probably have to define an alias different from the first level of your files. For example, if you have files, aaa.bbb that are defined to the master; then, the new alias can't be aaa; it has to be something different like aa1. Once the new alias has been defined, then the catalog pointers need to be merged onto the new user cat. If you have a utility such as TREX or Catalog Solutions, these utilities make this work much easier but IDCAMS can also do the merge of these records. Being user files, you may be able to just rename the files to your new alias provided these are not in use and there are no VSAM files involved; you can't rename a VSAM to an alias that's in a different catalog than the original vsam.

Of course this can impact other users who are looking to just get one or two datasets back. Other than writing an exit, is there any simple approach to prevent user's from submitting more than X recalls at one time?
