Analyzing the dump
The dump title includes the abend completion and reason codes, the failing
load module and CSECT names, and the release identifier.
The formats of SVC dump titles vary slightly, depending on the type of
error.
Figure 8 shows an example of an SVC dump title. Each field
in the title is described after the figure.
- ssnm,ABN=compltn-reason
-
- ssnm is the name of the subsystem that issued the dump.
- compltn is the 3-character hexadecimal abend completion code
(in this example, X'5C6'), prefixed by U for user abend codes.
- reason is the 4-byte hexadecimal reason code (in this example, X'00D303F2').
Note:
The abend and reason codes might provide sufficient
information to resolve the problem. See the WebSphere MQ for z/OS Messages and Codes manual for
an explanation of the reason code.
- U=userid
-
- userid is the user identifier of the user (in this example,
AUSER). This field is not present for channel initiators.
- C=compid.release.comp-function
-
- compid is the last 5 characters of the component identifier
(explained in Component-identifier keyword). The value L8200 uniquely identifies WebSphere MQ for z/OS.
- release is a 3-digit code indicating the version, release, and modification
level of WebSphere MQ for z/OS (in this example, 600).
- comp is
an acronym for the component in control at the time of the abend (in this
example, LOCK).
- function is the name of a function, macro, or routine in control
at the time of abend (in this example, CSQL1GET). This field is not always
present.
- M=module
-
- LOC=loadmod.csect+csect_offset
-
- loadmod is the name of the load module in control at the time
of the abend (in this example, CSQLLPLM). This might be represented by an
asterisk if it is unknown.
- csect is the name of the CSECT in control at the time of abend
(in this example, CSQL1GET).
- csect_offset is the offset within the failing CSECT
at the time of abend (in this example, 0246).
Note:
The value of csect_offset might vary if
service has been applied to this CSECT, so do not use this value when building
a keyword string to search the IBM(R) software support database.
