-- snip -- Having said that, I heartily endorse the technology. We started mirroring DASD in the late 90's when we still had to use conventional channel extenders. However you do it, nothing improves performance more than money does. ;-) -- snip --
I agree Skip. Knowing that one has a copy of their data (be it Asynch or Synch) at another site is certainly a good feeling. Distance (and cost) often dictates which method of duplication is used. -- snip -- We are building a disaster recovery datacenter about 4 hrs. from our primary site. Does anyone have any information on XRC Global mirroring for z/OS and are there any good redbooks/manuals? -- snip -- Sharon, there are a lot of good publications on the IBM site (you didn't say what kind of hardware you're using). For example. DS8000 Copy services - SG24-6787 Implementing ESS copy services - SG24-5680 (a little old - but still good) DFSS Advanced copy services - SC35-0428 Also take a look at the XRC monitor. Take a look at some of the presentations that have been offered by Share in the past (you can thank Skip for one of those). (www.share.org) Attent Share. There are often very good presentations that give you a much deeper look into the hardware than you can get from a manual. You can also hear some real user experiences.
