In this article we look at a bunch of ways to optimize replication operations in Ms SQL Server
SQL Replication Operations, as the name suggests are the technologies used for copying and spreading the data along with the various database objects. Learn some easy and relevant tips to optimize Replication Operations in an SQL Server.
- Mention the Minimum Server Memory Option: One of the easiest ways to optimize the Replication Operations in an SQL Server is to set the least value possible in the Minimum Server Memory Option in order to avoid the error of low memory availability anywhere during the replication operations. The minimum memory you can set is 16MB.
- Don’t Publish Unwanted Data: Secondly, try not to publish unwanted and undesired data and once you succeed in doing so, you will notice a significant change in the overall performance on the server along with reduced traffic on the net and enhanced replication performance.
- Put Replication Distribution Component on a Dedicated Server: You may not know but when the replication activity increases on the server, the resources are constraint and as a result the Publisher loading reduces but surprisingly, it increases the network traffic. So, try to put the replication distribution component separately and one matching the publisher differently from one matching the distributor.
- Put Distribution Database Log & Published Database Log on Different Disk Drives: Another fact to know about replication operations is that logging depends on writing, so it is essential that the disk is in array with the SQL Server log files catering adequate I/O performance; moreover, if you maintain two drives, then you can ensure higher disk I/O performance as well.
- Enhance the Distribution Agent CommitBatchSize Property: In case you need to work with the transactional replication, try to enhance the distribution agent CommitBatchSize that actually specifies the exact number of transactions that are to be issued to the subscriber. Here the default value is 100.
- Decrease the Use of Snapshot Agent: Another important to bear in mind is that the Snapshot Agent copies data from the respective publisher to the distributor in a bulk that ultimately slow downs the performance, so try to decrease the usage of the Snapshot Agent or try it during the idle time of the CPU to that the performance is not affected.
- Enhance the MaxBcpThreads Property of Snapshot Agent: MaxBcpThreads Property helps specifying the bulk copy operations number that can run in parallel and by increasing this property value you can make the bulk copy operations run faster on an SQL Server.
- Enhance the Log Reader Agent ReadBatchSize Property: ReadBatchSize Property helps specifying the maximum number of transactions that are processed in the transaction log in a publishing database. You must know that the default value here is 500 and this property should be increased while dealing with a larger number of transactions in a publishing database.
- Try Static in place of Dynamic Filters for Merge Replication Operations: Since, an SQL Server needs more overhead in order to process dynamic filters instead of the static ones, you should try the static ones in place of the dynamic filters especially when you use Merge Replication Operations.
While Using MS SQL Server – always plan ahead for contingencies
A SQL Crash can occur in just about any SQL Server instance. Hence it is always prudent to remain prepared for contingencies and keep a sql server recovery application like DataNumen SQL Recovery handy. In case you encounter a crash, this exceptional piece of software can help you recover your records in the quickest possible time. The application is extremely easy to use and it can handle a wide range of storage media types.
