Stand-by (Oracle9i Data Guard) vs. Replication Folks,
I have a mission critical system we are architectonic right now. There is some argument of the merits of replication vs. using Standby database going on. Current we have 4 sites that we will be replicating data back and forth between. There are 3 kinds of data: 1. Network Critical data (must be available for entire network) 2. Regional Critical data (only used for a given region. site = region). 3. Regional non-critical data (this is data that is easily recovered from other operational data stores). I can load you up with details, but for now this is the general requirement. We want a given site to be able to work independently of the other sites in the event of network failure (WAN). What I'm looking for is your experience with using replication for HA solutions vs. stand-by databases. I've also considered using standby databases as a possible solution to this problem, along with using transportable tablespaces to re-sync the databases once everything comes up. I'm concerned with replication in that there is allot to break, and I'm concerned about synchronization issues in general with either solution. Thoughts? RF Robert G.
