Were the same features in both z/OS 1.11 and 1.13? If 1.13 had more features, mode would be dumped. I do know that the z/OS USS ROOT hfs/zfs grew significantly, irrespective of additional features. z/OSMF had several significant enhancements and was significantly larger as well, again, irrespective of additional features.
The above would account for the jump from +/- 22.6 tb to 23.25 tb. It does not account for the +/- .7 tb per week increase subsequent to the 1.13 cutover. HTH, <snip> We have a set of weekly full volume dasd dumps just for our non-sms mvs volumes (sysres, pre-ipl vols etc), housing many of our system datasets that are almost purely static...ie do not grow or do not get written to. On July 21st, the lpar that run our weekly full volume dumps was upgraded to zOS 1.13 (from 1.11). Prior to zOS 1.13, the accumulated size of these dataset dumps, as per rmm, averaged about 0.3 to 0.5 tb per week. Since zOS 1.13 these same jobs, with the exact same static datasets being dumped averages almost double the size in tb per week. It's almost as if compression is not working right anymore. Here is an example of the jcl used, it has not changed between zOS 1.11 and 1.13: ....snippage July 1: 22.58 tb << zOS 1.11 July 8: 22.57 tb July 15: 22.62 tb July 22: 23.25 tb <<< zOS 1.13 July 29: 24.02 tb Aug 5: 24.81 tb Aug 12: 25.42 tb Etc </snip> ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
