Note: A SYSMDUMP ABEND dump is always a
synchronous SVC dump. To analyze a SYSMDUMP, see
Analyzing an SVC dump.
ABEND dumps written to SYSABEND and SYSUDUMP data sets are useful
for analyzing problems in a program running under the operating system.
This program can be called any of the following:
- Installation-provided program
- An application program
- A non-authorized program
- A problem program
- A program in the private area
ABEND dumps are written for problems detected in two ways:
- Software-detected problem, such as:
- A nonzero return code from a called module
- A program check, abend code X'0Cx', that a recovery routine
changes to another abend code
- An erroneous control block queue
- Not valid input to a system service
- Hardware-detected problem, which is a program
check, abend code X'0Cx', that a recovery routine does not
change to another abend code
