IMS abends
An IMS(TM) application might abend in one of the following circumstances:
- A normal abend.
- An IMS pseudo abend, with an abend code such as U3044 resulting from an
error in an ESAF exit program.
- Abend 3051 or 3047, when the REO (region error option) has been specified
as 'Q' or 'A', and an IMS application attempts to reference a non-operational
external subsystem, or when resources are unavailable at the time when a thread
is created.
An IMS message is sent to the user terminal or job output, and the IMS master terminal.
The abend might be accompanied by a region dump.
