Hi Dave, If all of the CA7 datasets you need copied are on the same DASD volume, then something like IBM Flashcopy volume , EMC Snapshot copy volume, HDS Shadowimage volume or STK Snapshot copy volume may work. You could also PPRC the volume within the same DASD subsystem without needing any 'wires' between multiple DASD subsystems. You would still need to 'post process' the target DASD volume because the dataset names will be same as the source DASD volume ( maybe thats good, maybe not, depends on what you want to do with those datasets ). If the CA7 datasets resides on two or more DASD volumes, that is where it gets a little tricky. XRC can give you that multiple volume consistency. It is possible ( and supported ) to XRC within the same datacenter and within the same DASD subsystem. Your DASD subsystem must have the XRC feature activated, each vendor has their own method for providing XRC support. The z/OS setup for XRC is not that difficult because the System Data Mover ( address space: ANTMAIN ) is always running. However, if you have z/OS R7, then you may want to take a look at section: "5.1.5 FlashCopy Consistency Groups" in the manual: z/OS V1R7.0 DFSMS Advanced Copy Services.
All of the above assumes that the reason you need the 'parallel' copy of these datasets is because you do not want to "quiesce the application" ( CA7 ) that owns these datasets.
