Is the dataset VSAM or not? If there is no record type 14, 15, or 62 for the dataset, then your STC is not opening it. In that case, it could very well be deleted after 540 days of non-use.
In the 20+ hours between the last successful execution of the STC and the first time it was missing, there is plenty of time for the dataset to be deleted, renamed, or uncataloged. Also, the catalog search order could have been altered (e.g., someone added an alias or disconnected a user catalog). Or maybe the VTOCIX is damaged. Have you looked at the volume the dataset is supposed to be on to determine if it is really gone? What tool are you using to search the SMF records? Why did you skip record type 66? For that matter, unless you are using OS/390 V1, there are no record types 63, 67, or 68 anymore. What are record types 136 and 139? -----Original Message----- From: IBM Mainframe Discussion List [mailto:IBM-MAIN@bama.ua.edu] On Behalf Of willie bunter Sent: Wednesday, July 13, 2011 10:20 AM To: IBM-MAIN@bama.ua.edu Subject: Re: DFHSM QUESTION - PRIMARY SPACE MANAGEMENT I went back as far as July 01 SMF records and nothing showed despite searching for records 14 15 17 18 61 62 63 64 65 67 68 136 & 139 --- On Wed, 7/13/11, Staller, Allan <allan.stal...@kbmg.com> wrote: From: Staller, Allan <allan.stal...@kbmg.com> Subject: Re: DFHSM QUESTION - PRIMARY SPACE MANAGEMENT To: IBM-MAIN@bama.ua.edu Received: Wednesday, July 13, 2011, 10:08 AM <snip> Again, if the dsn was deleted by a TSO user wouldn't it show up in the SMF records? </snip> Absolutely. Since you indicated in another post the data set was "in use" as of July 10th by an STC, I would go back at least to the start date/time of that STC for you SMF hunt. Again, DAF is your friend. Just feed it the raw SMF data...
