We are evaluating Dbvisit standby for maintaining a reporting database in a less secure network area. Is it possible to enable SSH only in one direction, from Primary to Standby, with no traffic allowed from standby server to the primary? Would such a restriction rule out the use of Dbvisit Standby?
With Dbvisit Standby there is actually a setting called
BLIND which enables this kind of scenario.
BLIND=Y in the DDC enforces this, and allows one-way communication of Dbvisit Standby from primary to standby for ultra secure configurations which only allow one-way traffic.
However, with this there is reduced Dbvisit Standby functionality. So it is important to be aware of this:
- No checkums.
- No log gap reporting.
- No Resync.
- No creation of standby database options available.
There are also restrictions around using Dbvisit Standby (rather than a logical replication tool such as Dbvisit Replicate) for reporting purposes. But you are most likely aware of these already.
