PSB authorization checking by CICS

At PSB scheduling time, CICS® invokes security checking to determine whether the terminal user is authorized to access the PSB. The actual check is carried out by an external security manager, which can be RACF® or your own security program.

Although PSB scheduling requests are sent to DBCTL for processing, CICS does PSB authorization checking. For programming information about writing your own security program, see Invoking an external security manager.
