Beware implementing standby/dataguard databases over slow network

I was under the false impression that if you had your remote destination (log_archive_dest_2) configured with ARCH and OPTIONAL, then problems with transmitting the logs to your standby could not impact the primary database. This is very far from the truth - in fact, even this configuration can very easily bring your primary database to a complete standstill (at least in 9.2.0.6 and earlier) as I had the joy of learning today. If you're new to standby/dataguard databases as I am, I highly recommend reading Metalink note 260040.1. Hopefully this will help someone else avoid the pain I went through today.  

Regards,
Brandon
