What is replication in SQL?

Replication is a set of technologies for copying and distributing data and database objects from one database to another and then synchronizing between databases to maintain consistency. Merge replication is primarily designed for mobile applications or distributed server applications that have possible data conflicts.

What is replication and its types?

Types of Replication: Snapshot replication sends the entire data set to the subscriber. Transactional replication only sends modifications to the data. Merge replication items are modified at both the publisher and subscribers. Heterogeneous replication allows access to other database products.

How does DB replication work?

Replication is the process of copying data from a central database to one or more databases. The central database is called the publication database because it provides the data for users at other sites. The data in the publication database is copied (replicated) to subscription databases at other locations.

How do I turn off replication?

Using SQL Server Management Studio

1. Connect to the Publisher or Distributor you want to disable in Microsoft SQL Server Management Studio, and then expand the server node.
2. Right-click the Replication folder, and then click Disable Publishing and Distribution.

How do you know if replication is configured in SQL Server?

To monitor the Snapshot Agent and Log Reader Agent

1. Connect to the Publisher in Management Studio, and then expand the server node.
2. Expand the Replication folder, and then expand the Local Publications folder.
3. Right-click a publication, and then click View Log Reader Agent Status or View Snapshot Agent Status.

How do I remove an article from transactional replication in SQL Server?

What is log reader agent on SQL Server?

The Replication Log Reader Agent is an executable that monitors the transaction log of each database configured for transactional replication and copies the transactions marked for replication from the transaction log into the distribution database.

What is replication latency?

Replication latency is the amount of time it takes for a transaction that occurs in the primary database to be applied to the replicate database. The time includes Replication Agent processing, Replication Server processing, and network usage.

How do I know if my Log Reader Agent is running?

This example uses the Log Reader Agent. Right-click the agent of interest > Properties. Select the Steps page, and then highlight the Run agent step.

How do you check for latency in replication?

1. Expand a Publisher group in the left pane, expand a Publisher, and then click a publication.
2. Click the Tracer Tokens tab.
3. Click Insert Tracer.
4. View elapsed time for the tracer token in the following columns: Publisher to Distributor, Distributor to Subscriber, Total Latency.

What is latency in SQL Server replication?

Monitoring SQL Server Transactional Replication It is necessary to implement a latency report to monitor and alert if latency is above a certain threshold that you define. It could be 5 minutes, 10 minutes or even a few seconds depending on your environment and service level agreement (SLA) with the users.

How can SQL Server improve replication performance?

Improving Performance

1. Use a dedicated log drive for the published and distribution databases.
2. Maintain VLFs on log files for published and distribution databases.
3. Use SSDs for log drives.
4. Replicate stored procedures.
5. Use non-default agent profile settings.

2. Right-click the Replication folder or any of its subfolders, and then click Launch Replication Monitor.

What is the difference between replication and mirroring in SQL Server?

Mirroring refers to keeping copies of database to a geographically different location. Replication referes to creating multiple copies of data objects of a database for distribution efficiency. Replication is done to create a copy of database objects and can be copied to a different database as well.

What are the types of replication in SQL Server?

There are four MS SQL Server replication types: snapshot replication, transactional replication, peer-to-peer replication and merge replication.

• Snapshot replication.
• Transactional replication.
• Peer-to-peer replication.
• Merge replication.
• Configuring users for MS SQL Server.
• Importing a database from a backup.

What is replication in server?

SQL Server replication is a technology for copying and distributing data and database objects from one database to another and then synchronizing between databases to maintain consistency and integrity of the data. In most cases, replication is a process of reproducing the data at the desired targets.
