I'm particularly interested as we test our failover every 3 months and last
time we did so there was a power outage on the standby which was running
temporarily as primary which we hadn't anticipated. The start up script
tried to bring what was currently a primary db as a standby. I'm trying to
automate this and yuk without dg broker which has its own set of problems
I'm a bit stymied!
I'm not suggesting Nat West hadn't tested thir failover , but imagine its
difficult due to volumes.
