On TWS one nit: You can't have the hot standby be in another plex as it communicates with the active controller using XCF.
Probably not a show stopper.

Some resources are 'sharable', some not. A. Can we use a unique TWS controller to Schedule jobs on two? I don't know whether you can, but you don't need to. We have one 'TWS controller' for the whole enterprise; it controls everything. From the LPAR where we run the controller, most jobs get submitted to run on other systems/nodes. We also submit jobs to midrange (Unix). B. Can we use RACF RRSF to propagate our pwd over IP between them? We have used RRSF between sysplexes for decades. We happen to use APPC for the purpose, but I don't see why IP would not work. Just be aware the AFAIK *all* RACF values will be propagated, not just passwords. I would seriously question whether you want all userids from production to be replicated on dev. That's a business decision, not a technical one. C. Can we share dasd (write one side at a time, not pdse) with GRS (not MIM)? Absolutely not. Don't even consider it. You will go down in flames. . .

We are in the process to separate our current SYSPLEX in two : 1. for the production 2. for the dev/qualifications. A. Can we use an unique TWS controller to Schedule jobs on two ? B. Can we use RACF RRSF to propagate our pwd over IP between them ? C. Can we share dasd (write one side at a time, not pdse) with GRS (not MIM) ? Many Thank's ----- Answers: A. Yes, but there are recovery considerations. Have a look at https://urldefense.proofpoint.com/v2/url?u=http-3A__ibmsystemsmag.com_mainframe_administrator_tivoli_all-2Dschedules-2C-2Dall-2Dthe-2Dtime_&d=DwIGaQ&c=jf_iaSHvJObTbx-siA1ZOg&r=BsPGKdq7-Vl8MW2-WOWZjlZ0NwmcFSpQCLphNznBSDQ&m=SACkHo1IhhsLKFBRHQpeYGu7NlAm6NPhl86H1_9b7wo&s=y2iyJMpqwmErtFWlbl8FjYjOo-QM6oWsSz0JTm49K8s&e= B. Yes, but there are operational differences. Have a look at http://www.redbooks.ibm.com/abstracts/sg248041.html?Open C. That's a nuanced question. Can you share DASD between sysplexes? Sure. Can you count on the data on the DASD being maintained with integrity with only GRS, probably not. Without something like MIM, you will need to use some other form of serialization that spans the sysplexes. The only thing I'm aware of is to use hardware RESERVE/RELEASE, which is fraught with its own set of management issues. You can search this group for probably dozens of discussions on the advantages/disadvantages of a hardware vs. software solution. Do you have a need to share tapes and tape drives?
