MQSeries.net :: View topic - Does anyone run their ZOS MQ in CDR Maintenance mode?

My client decided to cut costs and get MQ ZOS software in CDR mode. I've never supported ZOS MQ in CDR mode.

I was curious on how you do a backoff should there be a really bad defect when implementing a new release?

1) Do you bring down MQ and force a HSM backup or DFS backup of Queue Manager specific datasets before you upgrade so you could do a restore of those datasets on a backoff scenario?

2) In a DR, probably test one, have you come up where MQ couldnt recover and you had to cold start?

3) Any other factors to consider in CDR mode?

4) Should I update resume and branch?
