We have no choice. We must have at least on/two formal tests per year for our z/OS systems. All LPARs are brought up at DR site. Network settings are changed everywhere (our networks, our clients networks and MF network). All our clients are invited and they participate and report anything! From the moment we declare a DR (and shut down everything at Primary Site), we are up and running at DR site in a few hours and users can continue with their work from their own offices. Since those DR tests are just tests, when the exercise is completed, we started up our Prod systems and continue as if nothing happened. We obtain feedback from everyone about everything under the sun, moon and stars... Based on my recent posts ... Everything (IPL procs, Network changes, etc.) is documented (.boo and .pdf formats as well as URLs placed too) and placed everywhere on laptops, shared network resources, hardcopies, external drives, etc. This is to enable external people to continue our work if all of us are dead or kaput. (Or simply disappear a la Crysis (game) via a remote tool. ;-D ) Based on complaints about KC, I must mention that we even test connections to big blue websites from DR site. We (z/OS people) simply do not take any changes. Murphy and his laws are not welcome. ;-) Groete / Greetings Elardus Engelbrecht ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
