RE: 9i physical standby startup

My apologies, I was thinking only in the context of the question (which seemed to be concerned about accidentally messing up the standby through issuing a startup command).  

I'd guess SE would support a graceful failover using the pre-Dataguard method of copying the logfiles and recreating the controlfile from a backup to trace. But I don't have an installation to test that either.      

Thanks,

9.2 will issue an error.

10g will automagically mount it in read only mode

There is more than activate. You can also use the 'alter database commit to switchover to standby' on the primary, restart (nomount), 'alter database mount standby database', followed by 'alter database commit to switchover to primary' on the standby, with again a restart. This is a graceful switchover (switch roles between primary and standby) but I'm not sure whether SE supports this. No SE standby at hand to test. EE does.

Best regards,

Carel-Jan Engel

		Hi List, 
		To start up a physical standby database, you use
"startup nomount" and "alter database mount standby database;" .... 
		What if someone just types in "startup" and hits Enter? 
		Does the standby need to be recreate from zero? 
		Thanks, 
		Roger
