Chapter 7: The DataServer Tutorial Managing server attributes In OpenEdge Release 11, the DataServer for Microsoft SQL Server is enhanced to enable you to define foreign RDBMS constraint definitions within the meta schema of your OpenEdge database for use in migrating your database to a foreign data source. Once migrated to the foreign data source, constraint definitions can be pulled back into your OpenEdge schema holder. To achieve this, OpenEdge provides a submenu for the MS SQL Server Utilities for creating constraint definitions. Figure 10 shows the Server Attributes submenu. Figure 10: Server Attributes submenu From the Server Attributes submenu, you can access dialog boxes that provide an interface to create, view, and maintain server attributes, and define constraint definitions applied to the data and indexes of the foreign database within your OpenEdge schema holder. The dialog boxes accessed from the Server Attributes submenu are as follows: • View/Maintain Foreign constraint definitions — Use the View/Maintain Foreign Constraint Definitions dialog box, shown in Figure 11, to define and delete constraint definitions as well as view constraint definition properties. Figure 11: View/Maintain Foreign Constraint Definitions dialog box 278 OpenEdge Data Management: DataServer for Microsoft SQL Server
Managing server attributes See the “Defining constraint definitions in Data Administration” section on page 281 for details on how to define constraint definitions. See the “Modifying an existing constraint definition” section on page 288 for details on how to maintain constraint definitions. • Activate/Deactivate constraint definitions — Use the Activate/Deactivate Constraint Definitions dialog box, shown in Figure 12, to activate or deactivate constraint definitions you defined. Figure 12: Activate/Deactivate Constraint Definitions dialog box See the “Activating or deactivating a class of existing constraint definitions” section on page 289 for details on how to activate and deactivate constraint definitions. • Delete constraint definitions — Use the Delete Constraint Definitions dialog box, shown in Figure 13, to delete defined constraint definitions. Figure 13: Delete Constraint Definitions dialog box See the “Deleting an existing constraint definition” section on page 290 for details on how to delete constraint definitions. • Generate constraint definitions from ROWID — Use the Generate Constraints from ROWID dialog box, shown in Figure 14, to generate constraint definitions in an OpenEdge database from the ROWID designations that exist in the schema image of a connected schema holder database.
