Pseudoconversational programming is an online programming technique that frees certain resources while the system waits for a response from the online user. This permits an online environment to support more concurrent processing by conserving limited resources such as storage pool and program pool space.
To facilitate pseudoconversational programming in an SQL application, CA IDMS supports the SUSPEND SESSION and RESUME SESSION statements.
Updating After a Pseudoconverse
The online user's response may call for modification of data that was retrieved by the program. This section discusses techniques for updating after a pseudoconverse, including consideration of whether the program needs to verify that the data has not changed since it was retrieved.
