I was using multimaster replication between 2 sites on the local network. But I’m busy upgrading one of them from 8.0.6.2 to 9.0.1.3.
So I just drop replication and setup a job trough dbms_job instead.
The question is what are the differences between them bcz it's working properly.
What are the possible errors that i could expect?
Any suggested Link?

Alexandre
