Re: Detecting Controlfile Type

in 10g this work with dg_brker =true since the broker configuration  knows what the standby state should be.

Was that 11g ? 

They changed the default behaviour. An 11g database may open read only automatically, and turn on log-apply thereafter if you issue "STARTUP". Kinda naughty by Oracle me thinks, as this functionality requries additional licensing (active data guard option).

Well who knows if it's a bug, but yesterday due a mistake I executed
'startup' in a standby database ( synchronized via logwriter async ) and
the startup process mounted it and opened it (?)

Without executing nothing more, I did shutdown immediate and

startup nomount;
alter database mount standby database;
recover managed standby database disconnect from session;


And was applying archives and redo log syncing happily...
