Flexibility of SB use

IMS provides several methods for requesting SB.

You can request the use of SB for specific programs and utilities during PSBGEN or by using SB control statements. You can also request the use of SB for all or some batch and BMP programs by using an SB Initialization Exit Routine.

IMS also allows a system programmer or master terminal operator (MTO) to override requests for the use of SB by disallowing its use. This is done by issuing an SB MTO command or using an SB Initialization Exit Routine. The use of SB can be disallowed during certain times of the day to avoid virtual or real storage constraint problems.
