Not GRS-plex, not CA-MIM (or MII), but SYSPLEX. Reason: PDSE use sysplex communication, not GRS facilities. Regarding to the topic: in order to share datasets you need ...nothing. No parallel sysplex No base sysplex Not even GRSplex No SMSplex Simply nothing except DASD available from several systems. Of course, the more mentioned facilities you have the better sharing is. And yes, in order to share PDSEs (properly) you still have sysplex. However you can share ICF BCSes (catalogs), VSAM, PS, PDS, etc. Note: there are various flavours of sharing. Shared DASD as a data transport method, shared PDSes with jobs, REXX tools, etc. - it can be shared easily, because it is not heavily used. Batch datasets - assuming proper batch windows it is also can be shared easily. For frequent sharing it is good to think about ICF ECS or RLS, etc. -- Radoslaw Skorupka Lodz, Poland W dniu 19.06.2023 o 17:03, Michael Babcock pisze: > Beware of PDSEs.
