How to Create a Class

Applies To: System Center Operations Manager 2007

The following procedures explain how to create classes in the Operations Manager 2007 Authoring console. Before you perform these procedures, you must first complete the prerequisite procedure, How to Create a New Management Pack, in which you first create a new management pack before adding the classes shown here.

The classes created in the following procedures have these characteristics:

• Abstract class based on Windows Computer Role named MyMP.MyComputerRoleBase. Class has a single non-key property named Version and no key property.

• Two classes based on the abstract class named MyComputerRole1 and MyComputerRole2.

• Single application component hosted by a computer role called MyApplicationComponent. Class has a single key property named ComponentName.

To create an abstract class

1. In the Authoring console, select Service Model, and then select Classes.

2. Right-click in the Classes pane, select New, and then select Windows Server role.

3. In the ID box, type the name MyMP.MyComputerRoleBase.

   1. Right-click in the navigation pane and select Add Property.

   2. In the Choose a unique identifier box, type Version, and then click OK.

   3. In the Display Name box, type Version. Because you are expecting only a single instance of this class on a computer, it does not require a key property.

   4. Click OK.

9. Select File, and then click Save.
