Osservazioni

When you use the SQL Server Agent objects, you can reference them by using the JobServer object property of the Server object. It is not necessary to call the constructor for the JobServer object because it is automatically created when the constructor is called for the Server object.

[!NOTA]

If the CompatibilityLevel property for the MSDB database is set to Version70 SMO might throw an exception with a COLLATE error.

To get JobServer object properties, users must be a member of the SQLAgentUserRole database role on the MSDB database, or be a member of the sysadmin fixed server role.

To set JobServer object properties, users must be a member of the sysadmin fixed server role.

To run methods on the JobServer object, users must be a member of the sysadmin fixed server role.
