Standby database

I start my standby database as read only.
Now i want to restart the recovery process on my standby database.
How can i do it??
Should i manually copy the archivelog on the standby database??

Thank's in advance

The following steps should resolve the problem:

* copy any missing archive logs over manaually.
* Mount the database in standby mode.
* Issue the 'recover standby database' to allow the archive logs to be applied.
* Once the archive logs have been applied issue 'recover managed standby database'

Thank's Jim

Is it necessary to copy manually the archived redo log file to standby database from primary DB to continue the recover process?
Is SQL>recover managed standby database not enough to
make automatically the missing arch logfile on Stdby DB?

It's necessary to copy manually the archived log files from primary to standby DB after disabling READ ONLY STBY DB??

Thank's in advance!
