Re: Oracle Stream or Golden Gate?

Good question. I have pulled away from Oracle Streams and gone more towards Golden Gate. Depending on what you want to do with Golden Gate, it is the better solution. Deploying Golden Gate for just a disaster recovery or migration purposes is fairly quick unless you need to replicate DDL statements (simple but takes a little longer). Golden Gate is flexible and can be used for many different use cases.

There is always maintenance with any technology you choose to go with. Golden Gate, I've found it mostly to be based on the needs of the end user. Trail files could take some filesystem space if not applied quickly or the extract/replicat processes abend. Overall, I would say that Golden Gate would provide less maintenance.

I'll answer any questions you might have if more details are needed. Just let me know.

The replica reporting db will be a RAC database and reside in the same cluster and same nodes as the prod database.
