ORA-16624 broker protocol version mismatch detected

Cause: This status is returned when the Broker detects a network protocol version number mismatch. This can happen if the sites in question are not running the same release of Oracle. The broker will permanently disable the sites that do not have the same network protocol version number as the primary.

Solution: Examine the release of Oracle installed on all sites to make sure they are identical. Once the Oracle releases are the same on all sites, delete and re-add the sites that were permanently disabled.
