USERCAT Error (Out of Space)
I've got this out of space problem in one of our user catalogs. Since this particular catalog is used by a bunch of STC, I was thinking of expanding the catalog this Sunday in a window. Here's my question...Is it possible to REORG the catalog to reclaim "dead space"? I've deleted about 600 entries but that only bought me about 4 hours until it got full again.

I would look at: a) clean up unneeded entries b) reorg c) expand the space d) split the catalog e) all of the above Dennis Roach GHG Corporation Lockheed Martin Mission Services Flight Design and Operations Contract NASA/JSC Address: 2100 Space Park Drive LM-15-4BH Houston, Texas 77058 Mail: P.O.

Re: USERCAT Error (Out of Space)
Catalog Recovery Plus from Mainstar.com will allow you to increase the size of your catalog, re-organize it with optimum CI sizes and move it if necessary to another volume, non-disruptively. In theory this can be done with multiple LPARs accessing the catalog. In practice I've done this type of catalog work during quiet times on Sunday. I suspect there are other products, CRP is just the one with which I'm most familiar.

Re: USERCAT Error (Out of Space)
You have to keep in mind that a usercatalog is basically a KSDS. When you delete records, there are keys associated with them. If new keys you add do not collate properly, then VSAM will add them to freespace at the end. A REORG would reclaim this space. There are a few products on the market that would allow you to do this without any downtime, T-REX from Dino-Software being one of them. However, if you have a maintenance window, you could use IDCAMS EXPORT and IMPORT. If you have more questions, feel free to contact me directly.

Re: USERCAT Error (Out of Space)
Sure, if you like living dangerously. You might consider allocating a new larger catalog then use Idcams Mergecat to move the entries. I would move them selectively ensuring that my most important HLQs were moved first. Also you will want to run Diagnose and Examine commands to make sure the catalog is clean. Good Luck, Dave O'Brien NIH Contractor PS. I have had Mergecat fail in the far distant past which is partially why I prefer CRP. That was years ago and I'm sure IBM has improved the code.

Re: USERCAT Error (Out of Space)
T-Rex is a nice product that might be able to help you in this situation. If you do have a window of downtime, the suggestion would be to perform an IDCAMS MERGECAT. If you're at the limit of alias entries, than you should split the catalog into multiple usercats. You should look at the size of the current usercat and the number of entries in the catalog.

Re: USERCAT Error (Out of Space)
George, As an FYI, I've completed hundreds of MERGECATS through many different releases of MVS without any problems. There was a problem many years ago with SMS managed data and a usercat move. I don't remember the specifics, but it was back in the ESA days. With a usercat of only 230 tracks, a MERGECAT into a larger catalog would not take much time and would be easy to verify the results. Be sure to back up the original usercat before doing any work. :-) Michael Spencer BMC Software -Original Message- From: IBM Mainframe Discussion List [mailto:ibm-m...@bama.ua.edu] On Behalf Of George Rodriguez Sent: Friday, May 15, 2009 10:22 AM To: IBM-MAIN@bama.ua.edu Subject: Re: USERCAT Error (Out of Space) >From all the responses that I've gotten, it seems a product is "highly" recommended.

Re: USERCAT Error (Out of Space)
George, Let me second Mike Spencer's recommendation to backup the catalog before starting. Depending on your level of experience, confidence both an Export and a Volume backup might be in order. Also make sure the HLQ of your backup is not an alias in the catalog being worked on. I saw a co-worker do that. He deleted the catalog and then could not access the now uncataloged SMS managed backup dataset.

Do the files created by Power Exchange have a timestamp in the DSN. If so, you have the old "creeping key" problem and a REORG for this catalog will need to be scheduled periodically.

Re: USERCAT Error (Out of Space)
> BTW, one list member, Larry Crilley, mention "creeping key" and I was wondering if anyone else has heard about this. George, The "Creeping key" - phenomenon comes up in a catalog when you have an application that constantly creates new dataset names containing either a sequence number or a date/timestamp (such as your application seems to do). As a new dataset gets cataloged, using a key higher than the previous ones, the record is written at the end of the chain of existing dataset names. Old datasets eventually expire and get deleted, leaving a deleted record somewhere in the catalog. What that means is that the catalog constantly grows, because each new dataset entry occupies new space within the catalog. "Holes" left within the catalog from previously deleted records hardly ever get reused. So, even if you have only a limited number of these datasets, the catalog grows and grows, using ever more space. A brief history lesson: This creepy phenomenon was first detected many years ago, when IBM introduced VSAM Usercatalogs. The VSAM usercatalog structure for GDGs (generation datasets) consisted of a GDG-base record and one physical GDG-entry record for each generation dataset (e.g.: ABC.DEF.G0001V00, ABC.DEF.G0002V00, etc.). As a '+1'-generation dataset was created, it was added after the '0'-generation record. The oldest generation record was deleted, if the GDG-limit was exceeded. Physically, within the catalog, the records looked like this (assuming a 2-generation limit): GDG-base-record, G0001V00, G0002V00 Adding a +1-generation: GDG-base-record, -deleted, G0002V00, G0003V00 Adding another +1-generation: GDG-base-record, -deleted, -deleted, G0003V00, G0004V00 And that's where the creepy part begins. Eventually, the CI used by these catalog records fills up, a CI-split is required and perhaps even a CA-split (and you know, what that means ...). These old VSAM Usercatalogs containing GDGs required constant care and frequent reorgs. (Well, IBM eventually solved this problem by inventing ICF Usercatalogs. Here GDG record structures are formatted differently and occupy a fixed amount of space that does not usually creep as each successive generation is added). Back to your application ... if it creates discreet dataset names containing timestamps or other constantly incremented sequence numbers, then you will encounter this problem and you will need to monitor and regularly reorg your catalog. The rate at which new datasets get created per day will determine the growth rate of your catalog and how frequent you will need to reorg. As far as I can see, the only way to minimize the impact of this application's behavior on other applications or users or even the entire system is to keep this application's datasets in a separate catalog. This allows a catalog reorg to be scheduled when it's convenient for the application, with little to no impact on others.

Re: USERCAT Error (Out of Space)
Hi Ulrich, Thanks for the information... The brief history lesson was perfect in explaining how this all got started. Before I take any additional steps to migrating these datasets to their own catalog, I'm going to pursue this with the vendor... Thanks again!
