When an event occurs, Windows System Resource Manager will evaluate the states associated with the event, and if no state is true, the default policy associated with the event will be applied.

To configure the default policy associated with an event

1. Open Windows System Resource Manager. To open Windows System Resource Manager, click Start, point to Administrative Tools, and then click Windows System Resource Manager.

2. In the Connect to Computer dialog box, select This computer, and then click Connect.

3. In the console tree, right-click Conditions, and then click Add/Edit Conditional Policies.

4. In the Add or Edit Conditional Policies dialog box, click the name of the event that you want to configure, and then click Edit. The Conditional Policy Properties dialog box opens.

5. In the Select default policy list, select a resource allocation policy name.

   	Note
   	The default policy is only applied if no state configured as part of the conditional policy is true.

6. Click OK.

For Windows System Resource Manager to take action when an event occurs, you must configure at least one state to be evaluated in the conditional policy for the event.

States are evaluated in the order in which they are listed from top to bottom. After a state is found to be true, Windows System Resource Manager will switch the managing policy to the policy associated with that state, and no other states will be evaluated.

• To change the order in which states are evaluated, in the Conditional Policy Properties dialog box, under States, click the state that you want to move, and then click the up or down arrows to move it.
  
  
• To exclude a state from evaluation, clear the check box next to the state.
  
  

  	Note
  	If no states are selected for evaluation, no action will be taken when the event occurs.

To configure additional states to be evaluated when an event occurs

1. In the Add or Edit Conditional Policies dialog box, click the name of the event that you want to configure, and then click Edit. The Conditional Policy Properties dialog box opens.

2. Under States, click in an empty row to access the details configuration and create one or more clauses.

   	Note
   	You cannot configure the name of a state that has no clauses. The name column will be populated with information from the clauses that you define.

3. Under State details, click in an empty cell in the Category column to select a category from the list.

   • If you selected Processor or Memory, click in the Operator column to select an operator, and then click in the Quantity column and type the number of processors or a memory quantity [in megabytes (MB)].
     
     
   • If you selected MSCS, in the Object Name list, click and type the name of the node or resource group, and then in the State column, click to select a state from the list.
     
     

4. When you are finished creating state clauses, under States, click the Policy Name column in the row for the state that you just created. In the list, select a policy to apply when the state is true, and then click OK.

You can group state clauses so that one or more clauses must be true for the group to be evaluated true.

• AND and OR operators have equal precedence.
  
  
• Expressions are evaluated from left to right.
  
  
• Grouped clauses are evaluated first. In the case of a nested group, the deepest nested group is evaluated first.
  
  

To combine state clauses to be evaluated as a group

1. In the Add or Edit Conditional Policies dialog box, click the name of the event that you want to configure, and then click Edit. The Conditional Policy Properties dialog box opens.

2. Under States, click an empty row to create a new state, or click an existing state row.

3. Under State details, add multiple states that you want to combine as a single clause to be evaluated true or false.

4. Under State details, click the first row that you want to combine with another row, and then press SHIFT+click at the same time to select rows to combine.

   	Note
   	You can only group rows that are consecutive. Nested groups are supported.

5. Right-click the selected rows, click Add Group, and then click OK.
