Recently, I encountered a problem about the setting of commitbatchsize and commitbatchthreshold in SQL Server transactional replication. The explanation in the BOL is vague: Commitbatchsize "is the number of transactions to be issued to the subscriber before a commit statement is issued. The default is 100 ." Commitbatchthreshold "is the number of

In SQL Server replication, when 1 large transactions are performed in the publishing database, such as a one-time operation of 100,000 or more million of data. When the operational data is completed at the publication database, the Log Reader Agent scans the transaction log and passes it to the distribution database at once. If the last transaction is not deliver

semi-synchronous replication. This mode can be used to ensure that the slave database receives the Binlog log sent by the master database and writes it to its own trunk log, and then feeds back to the master database informing that it has been copied.When this mode is turned on, the primary database automatically reverts to asynchronous replication mode when a t

During database migration, SSMs is used to perform view operations. However, after the view migration is complete, configure peer-to-peer replication. In the last step, an error is reported, and the subscribed part is not created successfully. For example: There is no way to delete the peering replication and recreate it, but an error is returned when deleting it:Cannot Execute as the Database Principal be

I. BACKGROUND In the context of replication, transactional publishing is the most widely used, and I have a scenario where there are basic and group two tables in the task database, and you need to provide some of the fields in the two tables to cache other programs, and the program needs to get the data in time. As a DBA you need to start with permissions and performance control, I use SQL Server's transa
