What is the conflict of the merge and P2P replication?
In merge replication, the subscribers can have different partitions of the data. In peer-to-peer, all nodes are identical. Merge replication has conflict resolution. Peer-to-peer does not.
How do you set up peer-to-peer replication?
Steps To Setup Peer-to-Peer Replication:
- Create distribution on all instances that are participating in Peer-to-Peer.
- Backup the databases to replicate then restore it in the subscriber node (data needs to be synchronized first before we configure peer-to-peer)
- Create publication.
- Configure Peer-to-Peer topology.
What causes conflict in peer to peer replication?
The application does an update of the data, which caused this conflict to occur. This requires knowledge of the data to determine if the conflicts can be accepted. NOTE: If using Peer-to-peer replication, make sure that alerts have been enabled.See How to: Configure Predefined Replication Alerts (SQL Server Management Studio) for details.
What happens when changes are replicated to more than one node?
If a row is modified at more than one node, it can cause a conflict or even a lost update when the row is propagated to other nodes. There is always some latency involved when changes are replicated.
When does peer to peer replication need to be rebuilt?
Yesterday we hit the dreaded conflict in our production/DR SQL peer-to-peer replication setup. My first reaction is usually “oh , we’re going to need to rebuild replication”, but we happened to have the best possible scenario where we had an update-update conflict.
Do you hate SQL server peer to peer replication?
I’d like to note that I personally hate working with SQL Server peer-to-peer replication (we’re running SQL 2008 R2 version), and it looks like some of the limitations of the solution are still an issue in SQL 2012. We have to quiesce (i.e. stop the application) in order to add new articles (tables, views etc), to the replication topology.
