RE: Parallel Replication of Single Table

I remember too being able to achieve parallelism (8.1.7) with CTAS or inserts across DB's too but I'm not able to achieve this now. I tried it from the source side and the target side without success. It's always serial.

Curious how you are able to test this.

Thanks

We are able to achieve parallelism (8.1.7) with CTAS or inserts across DB's as long as we initiate the SQL from the *target* side. In this case you will see the parallelism on both the source and target side. Use it fairly often to move massive amounts of data.
