You need separate CF's for DEV vs PROD as well. _________________________________________________________________ Dave Jousma Assistant Vice President, Mainframe Engineering david.jou...@53.com 1830 East Paris, Grand Rapids, MI 49546 MD RSCB2H p 616.653.8429 f 616.653.2717 -----Original Message----- From: IBM Mainframe Discussion List [mailto:IBM-MAIN@LISTSERV.UA.EDU] On Behalf Of Jaco Kruger Sent: Tuesday, February 17, 2015 3:58 AM To: IBM-MAIN@LISTSERV.UA.EDU Subject: Parallel Sysplex split Good morning, Currently, the Production Parallel Sysplex environment consist of all the Development and Production LPARs, which is distributed across 2 mainframes. Each mainframe contains a Production Coupling Facility(CF) LPAR. We will remove the Development LPARs from the Production Sysplex and add it to a new Development Sysplex. The following components are shared between Development and Production environments - DASD - All the z/OS volumes are accessible from all LPARs. Only volumes pertaining to an specific environment is ONLINE, e.g. only Production related volumes are ONLINE in the Production environment. - There is a number of volumes that is shared between the Development and Production environment - ECS - GRS - I/O gen - WLM - ZFS The following components are not shared between Development and Production environments - CATALOG - Each environment has its own Master Catalog - There is some User Catalogs that are being shared between the Development and Production environment - JES2 - DFSMS - DFSMShsm - DFSMSrmm - VSAM/RLS The Control data set are shared The CF lock structure is shared The CF cache structures are unique - RACF - TCP/IP - VTAM We have reviewed the different components, performed the required cleanups and setup documentation with proposed actions. We do however have some questions - What are the gotchas that we need to look out for ? - What will be the best approach to initialize the VSAM/RLS environment in the new Development Sysplex environment ? - Once the Development LPARs have been shut down, do we need to perform any task on the Production Sysplex environment to ensure that the IPL of the Development environment into the Development Sysplex will not cause any problems for the Production Sysplex ? - We found little information regarding the split of a Parallel Sysplex. We used the redbook Merging Systems into a Sysplex as a reference, although it does not contain information regarding the split of a Sysplex. Is there any documentation available that has more information ?
