JESALLOC

Unlike the TSO ALLOCATE command, you can use this command to allocate a subsystem data set even when a JES connect was performed, which occurs when JES is started after the MainView AutoOPERATOR subsystem is started.

If the MVS Dynamic Allocate service detects errors, TSO/E generates IKJnnnn messages that are written to the BBI Journal.
