Hi, I have three identical databases say A, B and C. I want to replicate from A and B to C. Meaning C will have its own data plus the data from A and B. I can not create a db link from A or B pointing to C for security reasons. Also handing over the stream_admin password of C to A and B to push their changes through streams is not very good idea. I can not have multimaster replication as C is not sending its change to A or B. Please suggest how this can be done? Is any one using streams to capture data from remote database to your data center? Seems like streams push technology is a security hole. Thanks Sandeep
