List,
As part of minimizing the downtime associated with some critical
applications, we are exploring the available options. We are planning a
hardware patch that will require us to shutdown the DBs.
We have a DR site where we can set up dataguard for non clustered
applications. I was looking into switch over, but it looks like switchover
needs shutdown and startup and hence there is an associated downtime (twice
- once switching over to standby and then again switching back). I also
found some tidbits online where people have complained about delay in
switching over.
If there is a smoother way (any such thing as transparent switchover?) with
dataguard I definitely want to explore the option before checking out other
options. We have a mix of 10g and 11g. Can the listers share their
experiences with DG.
