We have active-passive database replication in our system cluster, so passive db belongs to DR class of nodes. We're trying to design zero-downtime deployment so I went out with few ideas.
Since we have 2 databases schemas, is it possible to replicate only one and second one (which is not replicated) to use in full read-write mode?
Data guard is used to replicate data. In previous company, we did such thing easily with MySQL (free edition), but not sure is it possible with Oracle. For me, if MySQL can do it, Oracle can as well, but internet is not providing me the exact answer on it.
I read somewhere that it's possible to do some EXCLUDE commands and to limit what is going to be replicated, but need to use that excluded schema in full read-write mode.
Thanks
