Error while duplicating Oracle database after failover, using 11.2.0.4

Question

I've recently updated oracle from 11.2.0.1 to 11.2.0.4 and my redundant system is no longer able to recover from failover.

I'm using scripts both on primary and standby node to get back to a state where it is possible to install them as a redundant system again.

It is possible to run the reset script over and over again in all states exept after a failover is performed. The only change is the upgrade to 11.2.0.4. it worked like a charm in 11.2.0.1

I am using Data Guard Broker to maintan the redundancy.

The setup procedure is complicated and is hard to explain here, so I am just asking if someone have faced the same error, and might have a solution how to recover from such situation.

At least, this is the output where it fails: (Backup step is performed prior to duplicate action)

Some LOG sequence hasn't been found. Given you request 159, it's that one, or lower.

How do you get that number ? The answer to that, may explain something already. Usuall, it's just a little too high.

Doesn't the ALERT tell you something more ? If you do restore, always have your alert tail-ed.
