Types of Partitioning Requests (Magic xpa 3.x)

Partitioning requests can be asynchronous or synchronous.

• Asynchronous requests are submitted to the remote server, and the calling programs continue immediately. Asynchronous requests are typically used for batch tasks, such as reports and updates. The calling program can continue processing regardless of whether the task being executed is online or batch.

• Synchronous requests block the calling program until a response arrives or a time-out value expires. Use synchronous calls when the calling program depends on the completion of the remote processing.

For example, if the program expects data in the form of parameters or a result file, or if confirmation that the remote request has completed successfully is required.

Another interesting scenario is when batch programs invoke online programs on workstations. For example, the process of approving a large transaction might involve displaying a dialog at a manager’s workstation, allowing the manager to feed in some information into the process.
