Recovery for this exit depends on the environment that invokes the exit:

Main task

If general purpose subtasks are attached then the subtask ESTAE is in effect. If no general purpose subtasks are attached and you specified UNCOND=YES, then the $SUBIT $ESTAE is in effect.

FSS

ESTAE recovery is in effect.

USER

JES2 fails the request and SSI $ESTAE recovery is in effect.

However, as with every exit, your exit routine should not depend on JES2 for recovery. JES2 cannot anticipate the exact purpose of your exit routine and can therefore provide no more than minimal recovery. Your exit routine should provide its own recovery.
