This Natural profile and session parameter determines whether a memory dump is to be generated in the case of an abnormal termination during the Natural session.
Within a Natural session, the profile parameter DU
can be overridden by the session parameter DU
.
Possible settings | ON |
A memory dump is produced in the
case of an abnormal termination (TP-monitor dump dataset or
SYSUDUMP in z/OS batch mode or under TSO). Then the Natural
session terminates with the error message NAT9967 or NAT9974.
|
|
---|---|---|---|
OFF |
No memory dump is produced. In batch
mode, subsequent action taken by Natural is determined by the setting of the
CC profile parameter.
In online mode, Natural responds with the error message NAT0950, NAT0953,
NAT0954, NAT0955 or NAT0956. For further information on the abnormal
termination, you can use the system command
DUMP .
|
||
SNAP |
This setting forces an immediate
dump in the case of an abnormal termination during a Natural session. The
Natural session continues as with DU=OFF after the dump has been
taken.
|
||
FORCE |
This setting forces an immediate
dump in the case of an abnormal termination during a Natural session and
terminates the Natural session immediately. This is useful for testing purposes
in some environments.
Note: |
||
ABEND |
This works as with
|
||
Default setting | OFF |
||
Dynamic specification | yes | ||
Specification within session | yes | Applicable Statements: | SET
GLOBALS |
Applicable Command: | GLOBALS |
Notes:
DU
profile parameter may impair
the system performance considerably, due to I/O processing on the dump
dataset.
DU=ON
, DU=SNAP
or DU=FORCE
may cause buffer fragmentation which may result in a significant degradation in
system performance.
DUE
can be used to get a
storage dump for specific errors.
Under Natural Security: The setting of this parameter can be overridden by the Session Parameters option of the Library Profile.
