Hi All, I have Oracle Standard Edition installed and have two schema in use (call it prodA, prodB) in this database. I wanted to create two additional schema(s) (copyA and copyB) and want to maintain both in sync with original schema(s). I know streams can not be used since it is only Enterprise version feature. I currently use datapump for schema duplication but this is little bit different - since downtime is not acceptable (hence both should be in sync, almost!). I thought of following: 1> Instead create new users and allow full access to prodA and prodB via synonyms and hope all is ok - since we now have four users and could later on face issues of objects and links all over the place. Didn't like this idea. 2> Use replication for all objects and copy them over to copyA and copyB. It still wont allow copying of stored procedure code, which is large in our case. 3> Could proxy user can help? But I think they are for external users like in the case of application servers etc. Any other ideas? -Thanks, DP.
