I believe referenced usually means OPENED. I had a similar problem a few years back when we IPL'ed a system that had not been down in about 6 months. HSM came up first, and deleted some files related to Netview.

But the question is what does SMS consider to be 'unreferenced' - clearly the file is getting allocated but I am not sure if it is actually opened (this is a vendor product and the file usage may be optional). SMS claimed that the last time the file was 'referenced' was about the time I think that it was created. -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of Ted MacNEIL Sent: Monday, April 20, 2009 2:16 PM To: [email protected] Subject: Re: can SMS managed VSAM file be deleted while allocated >that is what i thought - the job would have had to be down at the time the file was deleted. >Unless there is some weird bug in the system. > thanks Ted You're welcome. Get DAF from the CBT, and run it against the SMF data for the time period in question. That should tell who/when. If it does match up with the job running at the same time, then not only do you have a weird bug, but you have a data integrity problem. But, I strongly doubt it! You should find the culprit, then you can use your favourite form of persuasion to stop them from doing again. - Too busy driving to stop for gas! ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
