I'm afraid I must respectfully disagree with the collective wisdom of the group :-)
The most technically correct answer to your questions is: it depends. We used to do the controller to controller method (IBM's PPRC), but have recently implemented IBM's XRC. XRC requires a live operating system running at the remote site to manage the replication. -----Original Message----- From: IBM Mainframe Discussion List [mailto:[EMAIL PROTECTED] On Behalf Of Mautalen Juan Guillermo Sent: Tuesday, January 02, 2007 7:59 AM To: [email protected] Subject: Data replication at a remote site - elementary doubt Hi, Sorry for this very basic question, but i am not a system programmer (just a RACF administrator). When you implement synchronuous (or asynchronuous) copy of your DASD data to a remote site, is it necessary for the remote site to have a z/OS system active? Or is the copy performed at a hardware level between both DASD controllers?
