The following sections describe the mechanisms available to process the data and the procedures for taking advantage of the CA Datacom functionality and for handling handle errors.
The initializer program for the server is passed a number of parameters. One of these parameters instructs the program to attach a number of instances of the server, allowing multiple servers in a single server address space. Each instance of the server uses a CA Datacom thread to connect to CA Datacom. The thread is disconnected only when the server is disconnected.
When CA Datacom data is requested, the server starts a FORALL. Data is sent to the Data Object Broker in variable length buffers up to a maximum of 31 KB, as shown in the following illustration. If a single request requires more than 31 KB of data, multiple 31 KB buffers are sent until the request is complete.
