Comentarios
A policy represents the relationship between an individual object or a target set of objects and a condition.
A target is an entity on an instance of SQL Server. It could be the instance of SQL Server, or a component of it, such as a database or a table.
A condition is a relationship between a facet and a Boolean expression that determine the state of the facet. A facet is a dimension of a target. For example, the target could be an instance of SQL Server, the facet is Database Mail, the expression specifies that it is installed on the instance and the condition is that Database Mail is installed. Thus, the policy is that Database Mail is installed on the specified instance of SQL Server.
The evaluation mode of the policy determines how and when the policy is checked and enforced.
Using the Policy object, you can manage the following characteristics of a policy:
Condition
Evaluation mode
Schedule
Target set filter using XPath expression
A job on evaluation success
A job on evaluation failure
A policy group
Ejemplos
C#
Policy p = new Policy(ps, policyName);
p.AutomatedPolicyEvaluationMode = execMode;
p.Condition = condition.Name;
p.ScheduleUid = schedule.ScheduleUid;
if (execMode != AutomatedPolicyEvaluationMode.None) p.Enabled = true;
p.Create();
