As bee oh double beee double eeee says: It is a multi-platform muti-people environment. I have found that a service level agreement ( SLA ) to be an option so that upon failure to recover you can produce your SLA and show that it has been satisfied. Now that you have seen the BS side of DR lets go on. You need to recover all platforms and here in lays the problem. I have recovered all platforms in testing but have yet to get all platform in sync. This is a major goal but I feel it is the holly grail I seek. I am "lucky" to be "in charge" of all MQ platforms and am the DRC too. I still have trouble getting the admin of NT/AIX/WIN2000 machines to agree on a single backup strategy. I still believe that MQSeries can be taken up a notch in this area. As for having a plan? I suggest test and test and fail and fail until someone takes note. I find that non-Mainframe people do not understand what true recovery is. You have to show them and hold their hands and cuddle and whisper ( getting uneasy yet? ) until they see the light. The bottom line is this. How do you define a point in time that can be recovered and is acceptable to your business and or business units. DR Its not just a job its an adventure ;-)

My favourite topic ...ha! ha! Everytime you mention DR and MQ to IBM you get pointed to the manual/redbook about restart/recovery. But as Bobbee points out DR is potentially much more than this. Which of Bobbee's three options are people adopting ? Or are you doing something else ? Like just hoping you never have a disaster ? mqm --- "Anderson, Lizette T.
