ORA-16624: brokerprotocol version mismatch detected
Cause: A network protocol version number mismatch wasdetected. This could
happen if the databases in the broker configuration were not running the same
version of Oracle. The broker would disable standby databases that were not
running the same version of Oracle as the primary database if this situationwas
detected.
Action: Examinethe version of Oracle installed on all databases in the broker
configuration to ensure they are identical. Once all of the databases in thebroker
configuration are running the same version of Oracle, reenable the standby
databases that were disabled.
