Remarks

Granting a proxy access to a subsystem doesn't change the permissions for the principal specified in the proxy.

Permissions

This stored procedure is owned by the db_owner role. You can grant EXECUTE permissions for any user, but these permissions may be overridden during a SQL Server upgrade.

Examples

A. Grant access to a subsystem by ID

The following example grants the proxy Catalog application proxy access to the ActiveX Scripting subsystem.

USE msdb;
GO

EXEC dbo.sp_grant_proxy_to_subsystem
    @proxy_name = 'Catalog application proxy',
    @subsystem_id = 2;
GO

B. Grant access to a subsystem by name

The following example grants the proxy Catalog application proxy access to the SSIS package execution subsystem.

USE msdb;
GO

EXEC dbo.sp_grant_proxy_to_subsystem
    @proxy_name = N'Catalog application proxy',
    @subsystem_name = N'Dts' ;
GO
