Couldn't agree more with the general consensus of the replies so far.
Whenever I encounter a standby database environment that doesn't have the
broker setup, first thing I question is why they're not using it.
I'm usually not a fan of one-command-do-it-all-automatic type of things,
but in the broker's case it's somewhat different since it's highly
transparent. I always do a switchover / failover like this:
You can neatly follow the progress and see everything it's doing. If
anything goes wrong, you'll see exactly why and what fails. On top of that,
the DRC logs are also highly detailed.
All in all, it's a great tool and should be part of every standby
environment.
