Running Business Objects in Component Services

See Also

Business objects can be executable files (.exe) or dynamic-link libraries (.dll). The configuration you use to run the business object depends on whether the object is a .dll or .exe file:

Note   When business objects on the middle tier are implemented as Component Services components (using GetObjectContext, SetComplete, and SetAbort), they can use Component Services (or MTS, if you are using Windows NT) context objects to maintain their state across multiple client calls. This scenario is possible with DCOM, which is typically implemented between trusted clients and servers (an intranet). In this case, the RDS.DataSpace object and CreateObject method on the client side are replaced by the transaction context object and CreateInstance method (provided by the ITransactionContext interface), implemented by Component Services.
