ORA-02072: discordancia de protocolo de red de bases de datos distribuidas02072. 00000 - "distributed database network protocol mismatch"*Cause: This should never happen between different PRODUCTION releases of ORACLE, but may happen between alpha and beta releases, for example.*Action: Upgrade the older release.
In summary, I can indicate you that this problem occurs when using a dblink do a query and that query in the target database by another dblink makes the query to a third BD.
However, this error had occurred in different versions 11.2.0.3 and 11.2.0.4, but applied the patch (17,890,099) in one of the databases and the problem was solved.
But now the situation is now given in versions 11.2.0.4 (in the 3 DB).
I need know if this same patch serves me or there is another for that purpose.

Excuse for my english
