You can view the object classes in the schema using either the Web administration tool, the preferred method or using the command line.
Web administration
Expand Schema management in the navigation area and click Manage object classes. A read-only panel is displayed that enables you to view the object classes in the schema and their characteristics. The object classes are displayed in alphabetical order. You can move one page backwards or forward by clicking Previous or Next. The field next to these buttons identifies the page that you are on. You can also use the drop down menu of this field to skip to a specific page. The first object class listed on the page is displayed with the page number to help you locate the object class you want to view. For example, if you were looking for the object class person, you expand the drop down menu and scroll down until you see Page 14 of 16 nsLiServer and Page 15 of 16 printerLPR. Because person is alphabetically between nsLiServer and printerLPR, you select Page 14 and click Go.
You can also display the object classes sorted by type. Select Type and click Sort. The object classes are sorted alphabetically within their type, Abstract, Auxiliary, or Structural. Similarly you can reverse the list order by selecting Descending and clicking Sort.
After you have located the object class that you want, you can view its type, inheritance, required attributes, and optional attributes. Expand the drop down menus for inheritance, required attributes, and optional attributes to see the full listings for each characteristic.
You can choose the object class operations you want to perform from the right-hand tool bar, such as:
When you are finished click Close to return to the IBM Directory Server Welcome panel.
