Which is exactly the way Oracle Data Guard 3.x for 8.1.7 EE works,
almost completely ksh-script based. There even is an alert-file parser
active. It can add datafiles to the standby database automatically....
If you are on 9i or higher, you can use tha archive_lag_target parameter
to perform the logswitch automatically. Saves a dbms_job or cron script,
thus reducing the chance of a failure there.
