CA Ideal was designed as a pseudo-conversational system under CICS. From the database environment, the DBMS CICS interface issues a checkpoint at the end of a CICS transaction, dropping all locks, that is, when CA Ideal issues a TRANSMIT. CICS virtual storage resources must also be freed at task termination and saved on some storage medium.
The point of a pseudo-conversational system is to free resources at the termination of each task to allow other tasks to acquire those resources without contention. This allows more transactions to process without requiring exponentially more resources.
CA Ideal uses three basic types of CICS storage:
In general, with the exception of certain global control blocks, CA Ideal will release DSA at the end of a task. Storage acquired from EDSA and Temporary Storage make up the CA Ideal session, which is released at the end of a session.
