I have two SQL servers 2014 Ent.edition (SERVER A, and SERVER B) designed for AlwaysOn Availability Group. There are 5 databases in the AG. I have been told that we need to replicate one of the databases ( Database A ) from the AOAG. I setup a transactional replication for database A, pointing to listeners which shouldn't cause any issue if a failover happened. Tested, worked just fine. I'm thinking to create two distribution database, each on a different server. The reason is; I'm trying to be redundant. If Distribution Server A is gone for any reason, I should be able to replicate database A from Distribution Server B. Is it possible, any alternative to this ?
Here is what my design is for Replication on AOAG.
Distribution Server A ( contains Distribution database ) - SQLSERVER 2014
two subscribers - Sv1 and sv2 - SQLSERVER 2008R2 STANDARD
Pbulishers ( SERVER A and B - from AOAG ) - SQLSERVER 2014
What I'm trying to do : Adding one more distribution server (B).
Distribution Server A ( contains Distribution database )
Distribution Server B ( contains Distribution database1 ) - SQLSERVER 2014
two subscribers - Sv1 and sv2 - SQLSERVER 2008R2 STANDARD
Publishers( SERVER A and B - from AOAG )
What i see as a challenge:
Can't configure remote Distribution server for possible publishers.
Help/ideas are welcome..!
