Tony, The tool I referred to is used to DB2 backups that can be online to MVS at the same time as the source system and volumes. You can also use it to clone a DB2 system. But you are right, I did not register the "NOT" in capitals.
If your DB2 environment can be isolated on dedicated volumes, along with a dedicated MVS catalog, then you could restore the original environment using reverse resynch, or use the vary offline/online procedure you refer to. VARY would leave the failed implementation on disk, but I'm not sure how you would use it with duplicate volume and datasets already online and allocated. If you needed it for problem isolation you would need to bring it online to another LPAR, or bring down the PROD system again. It you were using a tool like I suggested then you can use the same tool/procedure to copy the back-up environment over the top of the failed environment. This wipes out the failed implementation - you may not want that. If you really will not touch the backup environment then have you looked at backing up the whole DB2 kit and caboodle with DFDSS/FCV2, and using the same method to restore it should the need arise. No need to worry about the catalog as the restore would update it. The backups would need to have a different name though, and in this case the HLQ is usually the simplest thing to change. I'm not strong enough on DB2 to be sure, but with a Dataset level backup of "everything" using FCV2, I would think that the failed environment could be renamed to DB2FAIL.** and the standby copies renamed to your original PROD HLQ. I don't think there would be too much tailoring required after that to bring up the backup system. They would be running on new volumes, and the failed image would be available for problem determination. And no MVS catalog problems.
