  • Artikel

Applies to: SQL Server

Creates a database mirroring monitor job that periodically updates the mirroring status for every mirrored database on the server instance.

Transact-SQL syntax conventions

Syntax

syntaxsql 
sp_dbmmonitoraddmonitoring [ [ @update_period = ] update_period ]
[ ; ]

Arguments

[ @update_period = ] update_period

Specifies the interval between updates in minutes. @update_period is int, with a default of 1. This value can be from 1 to 120 minutes.

If update period is set too low, the response time might increase for clients.

Return code values

None.

Result set

None.

Remarks

This procedure requires that SQL Server Agent is allowed to run on the server instance. For the database mirroring monitor job to run, Agent must be running.

If database mirroring is started from SQL Server Management Studio, the sp_dbmmonitoraddmonitoring procedure is run automatically. If you start mirroring up manually using ALTER DATABASE statements, to monitor mirrored database on the server instance, you must run sp_dbmmonitoraddmonitoring manually.

Nota

If you run sp_dbmmonitoraddmonitoring before you set up database mirroring, the monitoring job will run but will not update the status table in which database mirroring monitor history is stored.

Permissions

Requires membership in the sysadmin fixed server role, or execute permission directly on this stored procedure.

Examples

The following example starts monitoring with an update period of 3 minutes.

SQL 
EXEC sp_dbmmonitoraddmonitoring 3;
