The parameters for z/OS batch can be specified as subparameters of profile parameter
OSP
or macro
NTOSP
.
Possible settings | See OSP Parameter Syntax. | |
---|---|---|
Default setting | See Keyword Subparameters. | |
Dynamic specification | yes | The parameter OSP can only be specified dynamically. In
the Natural
parameter module, use the macro NTOSP .
|
Specification within session | no |
The following topics are covered:
The OSP
parameter is specified as follows:
OSP=(keyword-subparameter=value,keyword-subparameter=value,...) |
For information on subparameter names and values, see Keyword Subparameters.
The NTOSP
macro is specified as follows:
NTOSP ABEXIT=value, * DUMPDSN=value, * LBPNAME=value, * LEHDLR=value, * SUBPOOL=value, * TIOBSZ=(value1,value2), * USERID=value
ABEXIT
| DUMPDSN
| LBPNAME
| LEHDLR
| SUBPOOL
| TIOBSZ
| USERID
ABEXIT=value
specifies the mode of abend
processing within Natural.
Value | Explanation |
---|---|
ESTAE |
Natural intercepts all abends and issues the appropriate
error messages.
This is the default value. |
SPIE |
Only program checks
(S0Cx abends) are intercepted.
|
OFF |
Natural does not intercept any abends or program checks at
all. This value corresponds to profile parameter DU =FORCE .
|
Note:
The setting ABEXIT=OFF
is not recommended because some functions, which
require the abend interception, will not work any longer. The usage of profile parameter
MT
will cause an abend
U0322
instead of error NAT0953 when the CPU time limit is reached.
DUMPDSN=value
can be used to define the prefix
for a dynamically allocated dump data set. Then each dump will be written by the z/OS
service IEATDUMP
to a separate data set instead of the standard data set
(SYSUDUMP
or SYSMDUMP
). This can be very helpful in batch
server environments when multiple dumps from different Natural sessions must be written.
The complete dump data set name will be as follows:
value.D&YYMMDD.T&HHMMSS.&SYSNAME.&JOBNAME
Value | Explanation |
---|---|
1 - 8 characters | High level qualifier for the dump data set name. |
' ' (blank) |
No dumps are written by means of This is the default value. |
LBPNAME=value
controls the sharing of the
local buffer pools when running multiple Natural sessions within the same region.
Value | Explanation |
---|---|
1 - 8 characters | Name of shared local buffer pool environment. |
' ' (blank) | The local buffer pools are not shared.
This is the default value. |
Notes:
LBPNAME
defines the name of the shared local buffer pool
environment, and is used to locate the shared local buffer pool.
LEHDLR=value
specifies whether Natural uses an
LE error handler for the call of LE subprograms.
Value | Explanation |
---|---|
ON |
An LE error handler is set up by Natural during the call of
LE subprograms. This means, if an unhandled LE error occurs during the execution
of an LE subprogram, Natural will get control and can handle it (by issuing
error NAT0954).
This is the default value. |
OFF |
No set-up of an LE error handler is done by Natural during the call of LE subprograms. This means, if an unhandled error occurs during the execution of a LE subprogram, the LE enclave is terminated and so the Natural session is lost. |
Notes:
NATLEOPT
in the Installation for z/OS
documentation.
SUBPOOL=value
specifies the storage subpool for
GETMAIN
requests.
Value | Explanation |
---|---|
1 - 127 |
Subpool number. |
0 |
This is the default value. |
Notes:
SUBPOOL
is honored only in the Natural parameter
module which is linked to the batch driver, but not in an alternative
parameter module which is activated using a PARM=
specification.
SUBPOOL
is evaluated during session
initialization only, it cannot be specified as a dynamic subparameter.
TIOBSZ=(value1,value2)
specifies the size of the primary I/O buffer for batch and/or server processing.
Value | Explanation |
---|---|
|
Size of the primary I/O buffer in KB. |
(8,64) |
This is the default setting. |
TIOBSZ=10
or TIOBSZ=(10)
defines only the batch size.
TIOBSZ=(,33)
defines only the server size. The value which is not
specified will remain unchanged.
USERID=value
specifies the content of the
system variable *INIT-USER
.
Value | Explanation |
---|---|
ON |
The variable is set to either the user ID from the security
access control block (ACEE) if a security package (as RACF or ACF2) is involved
or the USER parameter from the job card.
|
OFF |
The user ID is the job name.
This is the default value. |
Notes:
*INIT-USER
can be changed by the user
ID exit NATUEX1
during session initialization.
OSP=(LBPNAME=NATTEST1,USERID=ON)
NTOSP LBPNAME=NATTEST1,USERID=ON
