Here is what I do (when copying prod to QA files) - there might be easier or better ways - but this is the best I came up with, with my limited mental resources .....
Get the name and size (# of tracks) of each of the 1500+ files (we use CA-RSVP) Sort by size (descending) Then write a process to read in each dataset name/size - assign to the volume with the most remaining space (you would need to keep track of how much is allocated for each volume) - sort the output by volume/#tracks Then you could backup the datasets for each output volume in the sorted order (one backup per TARGET volume) - then restore each backup with any rename you need to the target volume Why go to all this trouble? Even if you have enough volume space, if you don't restore the biggest files first, you might end up with enough free space for a large file, but not have enough spce on any ONE volume (perhaps not even a primary extent) Chris hoelscher Technology Architect Database Infrastructure Services Technology Solution Services 123 East Main Street Louisville, KY 40202 [email protected] Humana.com (502) 714-8615 (502) 476-2538 -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of Gibney, David Allen,Jr Sent: Thursday, October 08, 2015 9:54 PM To: [email protected] Subject: Re: [IBM-MAIN] File Placement Utility > -----Original Message----- > From: IBM Mainframe Discussion List [mailto:[email protected]] > On Behalf Of Hardee, Chuck H. > Sent: Thursday, October 08, 2015 6:25 PM > To: [email protected] > Subject: File Placement Utility > > I have a need to juggle the locations of 1500+ files on 70 volumes. > These packs are not SMS managed and will never be. > There will be 4 sets of these files across 4 sets of 70 DASD volumes. Sorry, I missed the number of output volumes, and you will need to use the FILTERDD to spcify more than 255 datasets. Still, it should work. If you want copies, then don't use DELETE or CATALOG. I suspect that in general is will just start writing and when each volume fills up, it will move on to the next one. Any more desire at a specific placement would probably be unique to your shop. > > Does anyone know of a utility, REXX, EXCEL, executable program, etc, > that would let me feed in the file names and sizes, dasd > characteristics, etc, and produce a list of what files should be allocated on > what packs? > > The file sizes vary file to file, but they do not expand or contract > once allocated and won't change until the next time the files need to > be adjusted, which won't hopefully, change for a while. > > Thanks, > Chuck > > Charles (Chuck) Hardee<mailto:[email protected]> > Senior Systems Engineer/Database Administration EAS Information > Technology > > Thermo Fisher Scientific > 300 Industry Drive | Pittsburgh, PA 15275 Phone +1 (724) 517-2633 | > Mobile > +1 (412) 877-2809 | FAX: +1 (412) 490-9230 > [email protected]<mailto:[email protected] > > | www.thermofisher.com > > WORLDWIDE CONFIDENTIALITY NOTE: Dissemination, distribution or copying > of this e-mail or the information herein by anyone other than the > intended recipient, or an employee or agent of a system responsible > for delivering the message to the intended recipient, is prohibited. > If you are not the intended recipient, please inform the sender and delete > all copies. > > > ---------------------------------------------------------------------- > For IBM-MAIN subscribe / signoff / archive access instructions, send > email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN The information transmitted is intended only for the person or entity to which it is addressed and may contain CONFIDENTIAL material.
