Data replication versus CORBA or messaging

Hello This message was also posted 3 weeks ago, but I have never seen the answers (except the answers that were mailed to me directly), because the message and answers were removed from the server in about 1 week. I am looking for (good and bad) experiences with datareplication, using the tools from Sybase (Replication Server), Oracle, Informix (just released), etc. Besides the possibilities of the distributed RDBMS, including data replication, one can also consider the possibilities of a messaging system or an object request broker (CORBA). IBM customers report very good results of the IBM product MQ on the IBM internet site (http://www.software.ibm.com/is/enterprice). Has anyone made a study comparing the possibilities, advantages and disadvantages of CORBA or a messaging system with the advantages and disadvantages of a distributed RDBMS (with or without data replication)? If so I would like to here from this, especially how the results of this decision was keeping up in production. ============================ groeten, regards Toon Loonen Toon.Loonen@inter.nl.net ============================
