David, no bummer. You did well my young padawan. The "SWITCHOVER PENDING" is
the desired status. Now, you have to perform the switchover. Uncle Larry
wants you (with the pointer finger pointed in your direction) to perform
the following:
ALTER DATABASE COMMIT TO SWITCHOVER TO PRIMARY WITH SESSION SHUTDOWN WAIT;
Your database will then sprout a new set of online redo logs, if you don't
already have them created.
After that, you need to shutdown database (normal or immediate) and re-start it.
That's it. May the force be with you!
