Local Mode Programming with the Management APIs

Commerce Server 2007
For the latest version of Commerce Server 2007 Help, see the Microsoft Web site.

Commerce Server provides a way to access the management functionality of the following Commerce Server systems through more traditional, in-process APIs. These local APIs provide the best performance but do not provide the ability to run remotely across a network.

The difference between accessing one of these Commerce Server systems using the local APIs versus using the agent APIs is in how objects of the corresponding context class (shown parenthetically above) are created. After you create the context class for a particular Commerce Server system, you can use it to access the full object model for that system. For more information about developing with the individual systems, see the following topics:

The remainder of this topic summarizes how to create the various context objects so that subsequent operations are performed in local mode.

In order to use the local APIs that access both the run-time and management functionality of the Commerce Server Catalog and Inventory Systems, use one of the correct versions of the Create factory method of the CatalogContext class. The two correct versions both take an instance of the CatalogSiteAgent class as a parameter: CatalogContext.Create(CatalogSiteAgent) and CatalogContext.Create(CatalogSiteAgent, CacheConfiguration).

An obsolete version of the local API Create factory method takes instances of the CatalogSiteAgent class and the DebugContext class as parameters: CatalogContext.Create(CatalogSiteAgent, DebugContext). You should avoid using this version.

After you have created a local-mode instance of the CatalogContext class, and assuming that you have an Inventory System enabled for your implementation of Commerce Server (the InventorySystemExists property is set to True), you can retrieve a local-mode instance of the InventoryContext class using the InventoryContext property.

In order to use the local API that accesses the management functionality of the Commerce Server Marketing System, use one of the three correct versions of the Create factory method of the MarketingContext class. The correct versions take multiple parameters, including the name of the Commerce Server site, two authorization parameters, and optionally, several SQL Server time-out parameters: MarketingContext.Create(String, String, AuthorizationMode) or MarketingContext.Create(String, String, AuthorizationMode, Int32, Int32) and MarketingContext.Create(String, String, AuthorizationMode, Int32, Int32, Int32, Int32).

Which method you choose depends on whether you need to set the relevant SQL Server time-out values.

For an example of using the management functionality of the Marketing System in local mode, see Local Mode Programming Sample.

In order to use the local API for the Commerce Server Orders System, use the correct version of the Create factory method of the OrderManagementContext class. The correct version takes an instance of the OrderSiteAgent class as its only parameter: OrderManagementContext.Create(OrderSiteAgent).

There is no local mode access to the ProfileManagementContext class, and therefore, no local mode access to the designated management functionality of the Commerce Server Profiles System. However, you can use the classes in the Microsoft.CommerceServer.Runtime.Profiles namespace to get local mode access to much of the functionality of the Profiles System. To do so, create an instance of the ProfileContext class using one of its three constructors. All three constructors take various combinations of connection strings and profile definition catalog names, as well as an instance of the DebugContext class: ProfileContext(String, DebugContext), ProfileContext(String, String, DebugContext), or ProfileContext(String, String, String, DebugContext).

Which constructor you choose depends on which connection strings you choose to pass as parameters and whether or not you need to pass in a profile definition catalog name.
