aware of the following requirements and considerations: 1. The principal and mirror databases must share the Distributor. It is recommended that you use a remote distributor here, and the remote Distributor can provide greater fault tolerance if the publisher has an unexpected failover. 2. For merge replication, and for transactional replication using read-only Subscribers or queued updating subscribers, replication supports mirroring the publication database. Immediate updating of subscrib
Monitoring SQL Server Transactional replicationIn general, we can use the Replication Monitor in SSMs to monitor replication. But we can't stare at it for 24 hours, and we have to use an automated way to monitor it.

As mentioned in the previous series, SQL Server Agent jobs are composed of a series of job steps, each of which is executed by a separate type.
The SQL Server job is simply to execute the specified script at the prescribed time, which describes how to create a job backup database with SSMs (SQL Sever 2008).(0) Assume that the database you are backing up before you create the job already exists; second, you have started the SQL Sever agent (which is typically o

Recently, memory tables were used in a database in the online alwayson environment. After about a week, the monitoring program found a very serious problem.

Although SQL Server 2008 has so far been considered a new version of the database system. But it will continue to update. For this reason, database administrators still need to consider backward compatibility issues when deploying SQL Server 2008. In order to reduce the problem of later upgrades, it is necessary for th

The purpose of this automation is to use fixed partitions (partition numbers 01 ~ 05) to save the data. When the last partition is full, we will clear the data in the oldest partition and use the old partition space for the new data.
There are some restrictions on the environment where partitions are automatically managed by the application. One is that the partition data is displayed progressively, for example, the partition field is the auto-increment Id value, or the dat
