Log operations often have the following applications: 1. Loss of transaction log files LDF when we delete or LDF files are lost,

and the secondary database.

For example, SQL Server logins stored in the master database and SQL jobs stored in msdb, as well as other d

In today's article, I want to discuss in detail how the transaction logs in in-memory OLTP are written to the transaction log.

If the server has a firewall, port 135 is not blocked by the firewall. Run the "Telnet IP 135" command to test whether the peer port is open to the outside world.
