A few thoughts This is NOT purely an academic excersize - if an lpar crashed with a DS member on it, and the LPAR COULD NOT be immediately restarted. You would NEED to bring up the downed member on the remaining LPAR in light mode - to free any locked threads - miake sure all the drda ports are defined an ALL potential LPARS

(You can indeed run different DS members on a single LPAR) - we've done it during a DR exercise ) The question is more about do you have shared parmlibs/proclibs/RACF etc. etc. Some other considerations might be the listening ports for DDF (do the DS Members share a port or have unique ports ?) or ZFS file systems ?

The point of DB2 Data Sharing is there is a GROUP (Umbrella) that connects multiple DB2 Regions. So if you have 2 or more DB2 Data Sharing regions. One on LPAR1 one on LPAR2 Then if LPAR1 is down, then LPAR2 will take on the DB2 data sharing work. Does that make Sense?

We are planning to upgrade our development environment and we need to have the development CICS regions down. Unfortunately operations says they have difficulty going thru all the regions and just stopping development cics. Our CICS regions are connected to only 1 LPAR. So only in order to ease their work they want to just bring down that LPAR with a scheduled IPL. Our primary DB2 member runs on that LPAR. So I wanted to start it on a "non-CICS" LPAR.
