                                boolean pooled)

Description copied from interface: SLARuleInterface

Returns True is the rule's conditions have been met (SLA Violation).

This is used for non transactional rules. Implementors should access the database and perform whatever calculations are required in order to determine if the rule's conditions are met or not.

This function should never throw an exception.

The calling function is typically the NonTransactionalSLAProcessor which operates on a set schedule that can be adjusted by administrators. It operates using the Quarts schedulers

Since no data is provided, an implementor is expected to access data on their own. To access global settings

Open the fgsms databases

 Connection con =null;
 if (pooled)
  con= Utility.GetPerformanceDBConnection();
 else
  con = Utility.GetPerformanceDB_NONPOOLED_Connection();
 //or use Utility.ConfigurationDBConnection(); for the configuration database
 try {
 // do something
 } catch (Exception ex) {
 // log some message
 } finally {
 if (con != null) {
 try {
 con.close();
 } catch (Exception e) {
 }
 }
 }
 

Specified by:

CheckNonTransactionalRule in interface SLARuleInterface

Parameters:

pol - This is a reference the service policy that this rule is attached to. Do not modify, unexpected results may occur

params - per service policy, rule instance parameters this can be null

nullableFaultMsg - the human readable text explaining what happened or why the rule was triggered

pooled - Indicates the usage of pooled database connections or not

Returns:

true if the rule indicates that a problem has occurred
