hi,

I'm currently testing failover.
I'm working with oracle 9.2.0.6 on linux rh as3
The transmission mode is arch with 10 mn delay.

I have two questions to submit:

First:
In case the primary database stop brutally, last redo is not archive. So how apply it?

It must be copied (but which redo log, I have 8 group of redos?) and register to the standby.

How to do that?




second question:

what is the difference between



alter database commit to switchover to primary;

and

alter database activate physical standby database skip standby logfile;

U can use both commands to activate standby database.
how to choose between them?

thk in advance,
