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
