Re: Extending a VTOC
Thank you all for your input. Unfortunately I do not have FDR on this system. That would be a very good option (my problem is with files that have enqueues from active STCs, such as a few CICS address spaces. And the next programmed IPL is still a long way away... And this is a model 27 that on which was placed a VTOC that would be small on a model 3. So, there is free space on the DASD but not on the VTOC.

Re: Extending a VTOC
If you have FDR they have a very safe way of extending the VTOC.

Re: Extending a VTOC
The Extend VTOC is nice, but has one problem ... you could end up with your VTOC in multiple extents. I would back it up, empty the volume, and reinit.

I hope I'm only stating the obvious, but back the volume up before you do anything. -Original Message- From: IBM Mainframe Discussion List On Behalf Of Jack Zukt Sent: Monday, August 1, 2022 10:01 AM To: IBM-MAIN@LISTSERV.UA.EDU Subject: Re: Extending a VTOC Thank you all for your input.

Hi Jack, have a look at ICKDSF parameter "EXTVTOC(n): Expands the VTOC at its current location." This may do what you want.

Re: Extending a VTOC
In theory you can. The VTOC has to be contiguous, so the area on the disk just passed to current VTOC must be free. If that is not the case, you will have to move the files that occupy that space, or do it the old way, by emptying the dasd and reinitializing it with a larger VTOC.
