This is similar to a "no

Sometimes, you may first initialize a transaction subscription from the backup, and then you need to add a project (Article ). If the subscriber is initialized by a snapshot, you can re-run the snapshot agent to generate a new snapshot. Only the newly added project is output by BCP and then imported to the subscriber BCP. However, if you use backup to restore the created subscription Sometimes, you may firs

This article is the sixth of the SQL Server replication series, please refer to the original text for more information.

This article is the first of a series of TimesTen database replication.What is replicationReplication is the existence of multiple copies of data in multiple databases, with minimal performance impact while ensuring high data availability, balancing workloads in addition to data recovery to maximize performance and enable rolling upgrades and maintenanceTT replication is implemented in both the master and Subscriber databases with replication agents,
