Bi-directional Database availability

edited Nov 8, 2012 5:07AM in High Availability Data Guard, Sharding and Global Data Services (MOSC) 2 commentsAnswered
 Request expert inputs on below requirement for bi-directional database replication.There are 2 sites, SITE A (Primary) and SITE B (Secondary) with Active Passive DB setup (can possibly be implemented with data guard). 
Peculiarity of requirement arises from specific requirement  that in case anything goes wrong between link connectivity SITE A and SITE B,
- Users at SITE B should connect to SITE B DB  (Secondary, because it will be made active at that point)
- Users at SITE A continue to work on Primary DB
- Once the link issue is resolved, Primary and Secondary DBs need to be brought in sync with each other (Bi-Directional replication)

Howdy, Stranger!
