Dave, Each LPAR has its own RACF and Catalogs, and they are using SMS. This shop is currently running z/OS 1.9 on very old hardware, in the process of upgrading to current H/W and S/W.

You can "get away" with only and rarely updating from one LPAR, and reading in the others. Multiple RACF databases? Are the Catalogs the same and shared between all 3 LPARS? Is the site using SMS? > -----Original Message----- > From: IBM Mainframe Discussion List <IBM-MAIN@LISTSERV.UA.EDU> On > Behalf Of Gord Neill > Sent: Thursday, November 24, 2022 12:55 PM > To: IBM-MAIN@LISTSERV.UA.EDU > Subject: To share or not to share DASD > > [EXTERNAL EMAIL] > > G'day all, > I've been having discussions with a small shop (single mainframe, 3 > separate LPARs, no Sysplex) regarding best practices for DASD sharing. > Their view is to share all DASD volumes across their 3 LPARs > (Prod/Dev/Test) so their developers/sysprogs can get access to current > datasets, but in order to do that, they'll need to use GRS Ring or MIM > with the associated overhead.
