There are two options for configuration when we place the secondary database in standby mode:

• We can choose to have database users disconnected when transaction log backups are being restored. If we choose this option, users will be disconnected from the database each time the log shipping restore job attempts to restore a transaction log to the secondary database. Disconnection will happen on the schedule you set for the restore job.

• We can choose not to disconnect users. In this case, the restore job cannot restore transaction log backups to the secondary database if there are users connected to that database. Transaction log backups will accumulate until there are no user connections to the database.
