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

I have two questions to submit:

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;


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,
