If you were asking in a security context, I would advise against it in nearly all cases. Auditors will not like that a system's data can be accessed without reference to the RACF (or ACF2, or TSS) system that is supposed to protect it.
Lennie Dymoke-Bradshaw -----Original Message----- From: IBM Mainframe Discussion List <IBM-MAIN@LISTSERV.UA.EDU> On Behalf Of Gord Neill Sent: 24 November 2022 20:55 To: IBM-MAIN@LISTSERV.UA.EDU Subject: To share or not to share DASD 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. I don't know of any other serialization products, and since this is not a Sysplex environment, they can't use GRS Star. I suggested the idea of no GRS, keeping most DASD volumes isolated to each LPAR, with a "shared string" available to all LPARs for copying datasets, but it was not well received. Just curious as to how other shops are handling this. TIA!
