How do you resolve replication issues in SQL Server?

Verify that records are being replicated to the destination and that connections to the Subscriber, Publisher, and Distributor are still active. To fix the Snapshot Agent credential issue, right-click on the Publication, under the Replication node -> Local Publication, and choose the Properties option.

What is merge replication in SQL Server 2008?

Merge replication is a method for copying and distributing data and database objects from one SQL Server database to another followed by synchronizing the databases for consistency. According to the Microsoft SQL Server TechNet, merge replication is implemented by the SQL Server Snapshot Agent and Merge Agent.

On which basis merge replication works on?

Merge replication is implemented by the SQL Server Snapshot Agent and Merge Agent. If the publication is unfiltered or uses static filters, the Snapshot Agent creates a single snapshot. If the publication uses parameterized filters, the Snapshot Agent creates a snapshot for each partition of data.

How do you check SQL Server replication is working or not?

Connect to the Publisher in Management Studio, and then expand the server node. Expand the Replication folder, and then expand the Local Publications folder. Expand the publication for the subscription you want to monitor. Right-click the subscription, and then click View Synchronization Status.

How can SQL Server improve replication performance?

Server and Network

Set the minimum and maximum amount of memory allocated to Microsoft SQL Server Database Engine.
Ensure proper allocation of database data files and log files.
Consider adding memory to servers used in replication, particularly the Distributor.
Use multiprocessor computers.
Use a fast network.

What is the difference between transactional replication and merge replication?

Merge Replication is the same as SQL Server Transactional replication; however, Merge replication replicates data from the Publisher to Subscriber and vice-a-versa. Merge replication uses the Snapshot Agent and the Merge Agent.

What is the difference between merge replication and peer-to-peer replication?

Merge replication involves one publisher and multiple subscribers. In peer-to-peer, all nodes are both publishers and subscribers. In merge replication, the subscribers can have different partitions of the data. In peer-to-peer, all nodes are identical.

How do you check SQL replication is working or not?

How do you merge replication?

Step 1: First you need to initiate the SQL Server and select “replication” under the Configure Distribute options. Step 3: Select a New Publication and specify the database you want. Select “Merge Replication” and set the snapshot to start the process. Step 4: Specify a synchronization schedule.

What are the required constraints in merge replication?

Merge replication does not require a primary key, but if one is present, it must be replicated. Snapshot replication does not require a primary key. By default, primary key constraints, indexes, and check constraints are replicated to Subscribers.
