|
ADALNN |
The modules ADALNK and SSFB2C are
linked to the environment-dependent nucleus.
|
, (comma)
|
The module This is the default value. |
In any case a resolve to the Adabas module library has to be given in the linkage step for the environment-dependent nucleus.
See Adabas Priority Control for details. Possible values are:
Value: | Explanation: |
---|---|
YES |
Activates Adabas priority control for a Natural openUTM application. |
NO
|
The Adabas priority for all openUTM transactions is the same. This is the default value. |
This parameter enables you to realize synchronized processing and
coordinated restart of asynchronous transactions between openUTM and
Adabas. This requires that the module ADAUTM
is available; this
module must be linked to the Natural
environment-dependent
nucleus (see the Installation documentation).
Possible values are:
Value: | Explanation: | ||
---|---|---|---|
YES |
Synchronized processing and coordinated restart of asynchronous
transactions between openUTM and Adabas are enabled.
|
||
NO
|
This is the default value.
|
With this parameter, you specify the name of the Natural
openUTM application. The value of this parameter must be identical
with the value of parameter APPLINAME
in
KDCDEF
. This name is used to create a name for a task-specific
SYSLST
file (see also SYSLST
parameter below).
Possible values are:
Value: | Explanation: |
---|---|
name
|
Up to 8 characters long.
No default value is provided. |
The specified name is also used to construct a serialization marker for
the initialization routine in the Natural openUTM Interface; an
S
is inserted in the first free character position (for example,
if APPLNAM=NATUTM
, the name of the serialization marker is
NATUTMS
).
Furthermore, this name is used to create an Adabas user ID if
TID=N
is specified.
A defined character position of the operand of
APPLNAM
can be used for constructing the Adabas user ID;
see parameter TID
.
This parameter can be used to define the Adabas priority
nnn
for the standard openUTM
TAC (default NAT
). Possible values are:
Value: | Explanation: |
---|---|
nnn
|
Adabas priority nnn for
the standard openUTM TAC (default NAT ).
|
144
|
This is the default value. |
The APRISTD
parameter is only in effect if the
ADAPRI
parameter
is set to YES
. For individual TACs, individual priorities can be
defined with the parameters
TCLSn
and
TCLAn
; see also
Adabas Priority
Control.
This parameter specifies the name of the logical openUTM
communications partner (as defined in KDCDEF
) of the asynchronous
openUTM application. This name is only relevant in the case of
asynchronous transaction processing between two openUTM applications.
Possible values are:
Value: | Explanation: | ||

|
openUTM TAC for the openUTM task or application that runs asynchronously. |
NATAS
|
This is the default value. |
The specified openUTM TAC must be distinct from the "standard" Natural TAC and also from the TAC used for the synchronous openUTM application (if asynchronous transaction processing is used between two openUTM applications).
The first five characters determine the unique identifier for asynchronous openUTM TACs.
This parameter enables you to activate the openUTM function
BADTACS
, which means that in the assembled program of macro
NATUTM
, the startup program AUTOTAC
is generated for
undefined openUTM transaction codes. Possible values are:
Value: | Explanation: |
---|---|
YES |
Activates the openUTM function
BADTACS .
|
NO
|
This is the default value. |
Anmerkung:

definitions must be supplied when defining KDCDEF
and generating
KDCROOT
:
PROGRAM AUTOTAC,COMP=ASSEMB TAC KDCBADTC,CALL=FIRST,PROGRAM=AUTOTAC,EXIT=NUERROR,TYPE=D TAC AUTOCONN,TYPE=D,PROGRAM=NATUTM,EXIT=NUERROR,CALL=BOTH
This parameter specifies the maximum number of modules to be
dynamically loaded (for example, COBOL or Assembler subroutines) and/or the
number of modules which have been linked to the Natural
environment-dependent
nucleus (see the Installation documentation)
and declared with parameters LINK
to
LINK4
.
Possible values are:
Value: | Explanation: |
---|---|
nn
|
nn defines the number
of programs.
|
15
|
This is the default value. |
Anmerkung:
The programs to be dynamically loaded must be either in the load
library specified in the Natural parameter module or in the BLSLIB
library or libraries specified in the start job.
This parameter activates or deactivates the CLEAR key. Possible values are:
Value: | Explanation: |
---|---|
ON
|
Activates the CLEAR key (keys LSP and ENTER). This is the default value. |
OFF |
Deactivates the CLEAR key, which means that after pressing CLEAR, the entire last Natural screen is displayed again. |
This parameter controls whether the cursor can be positioned to a protected field. Possible values are:
Value: | Explanation: |
---|---|
ON
|
The cursor cannot be positioned to a protected field. This is the default value. |
OFF |
The cursor can also be placed in a protected field (for example, for field-specific help functions). |
This parameter allows you to generate an openUTM input exit
for messages in minus (-) format; that is, messages from a Natural screen. Such
an input exit controls the allowed (or not-allowed) user KDC
commands. Possible values are:
Value: | Explanation: |
---|---|
(YES,KDC xxxx (,KDC
xxxx ,...))
|
Any KDC command not allowed must be defined with
this parameter by specifying YES and the name of the
KDC command. See examples below.
|
(NO)
|
This is the default value. |
ICONTRL=(NO)
|
This example does not generate an input exit and allows all openUTM commands. |
ICONTRL=(YES)
|
This example generates an input exit with the name
ICONTRL and prohibits usage of all openUTM
commands.
|
ICONTRL=(YES,KDCOUT,KDCOFF)
|
This example generates an input exit with the name
ICONTRL and prohibits usage of the commands
KDCOUT and
KDCOFF .
|
If YES
is specified as first operand, the generated input
exit must be defined in KDCDEF
and KDCROOT
as
follows:
EXIT PROGRAM=ICONTRL,USAGE=(INPUT,USERFORM) PROGRAM ICONTRL,COMP=ASSEMB
This parameter defines the value for the Natural variable
*INIT-PROGRAM
.
Possible values are:
Value: | Explanation: |
---|---|
APPLNAM
|
The Natural variable
This is the default value. |
KCTACVG |
The Natural variable *INIT-PROGRAM
contains the value of the openUTM KB field KCTACVG
(openUTM start TAC).
|
This parameter specifies whether the address of the openUTM communication area KB (Kommunikationsbereich) is passed as the first parameter address each time Natural calls a non-Natural program. This has been taken account of in the subroutines and utility programs of the Natural openUTM Interface. Possible values are:
Value: | Explanation: |
---|---|
YES |
The address of the openUTM communication area (KB) is passed as the first parameter address each time Natural calls a non-Natural program. |
NO
|
This is the default value. |
This parameter specifies whether the openUTM KB will be saved
via SPUT
or not. Possible values are:
Value: | Explanation: |
YES |
The openUTM KB will be saved via SPUT ,
starting from the end of the KB header plus twelve bytes. This information will
be saved in the LSSB before a PEND PR is executed for a
user-specific partial openUTM program.
|
NO
|
The openUTM KB will not be saved. This is the default value. |
To be able to use this parameter, you must set the following
KDCDEF
definition:
MAX LSSBS=1
If the user-specific partial openUTM program resumes, the
original communication area will be refreshed via SGET
. This
allows the partial openUTM program to use the KB from the end of the
openUTM communication area header plus twelve bytes. Therefore, the
program must not destroy these twelve bytes. If a KB user extension is defined,
this area will not be saved.
This parameter specifies the length of a openUTM KB user extension. Possible values are:
Value: | Explanation: |
---|---|
nnnnn
|
nnnnn specifies the
length of a openUTM KB user extension.
The maximum length allowed is 30720 bytes. |
0
|
This is the default value. |
Length and address of a user extension are stored in the KB:
USEREXTL DS |
H |
length in bytes
|
USEREXTA DS |
F |
address
|
For more information, see the DSECT
macro
CMBS2TP
.
This parameter specifies that the Adabas large file handler (LFH) is to be used. Possible values are:
Value: | Explanation: |
---|---|
YES |
Specifies that you are using the Adabas LFH. |
NO
|
This is the default value. |
If you specify YES
, you also must define the buffer size
for the Adabas LFH in the Natural parameter module (parameter
VSIZE
).
This parameter enables you to specify the names of programs and modules that are called from Natural programs and linked with the non-reentrant part. Possible values are:
Value: | Explanation: |
---|---|
name
(name,
name,...) |
The Conversely, the programs and modules whose names are specified
must be linked with the non-reentrant part, otherwise the application is put
into status |
A TABLE
macro call is performed for the specified programs
and modules, which enters their load addresses into the dynamic loader's link
table. It is therefore not necessary to dynamically load these programs when
they are called by Natural programs.
Example:
LINK=PROG1 LINK=(PROG1,PROG2,MODUL111)
These parameters are an extension of the parameter
LINK
. Possible
values are:
Value: | Explanation: |
---|---|
name
(name ,
name,...) |
The syntax is in analogy to that of
LINK . See examples below.
|
No default value is provided.
Since an operand definition must not be longer than 127 characters
(including parentheses), the parameters LINK2
to
LINK4
are provided for cases where the operand of
parameter LINK
would be too long.
NATUTM LINK=(PROG1,PROG2,...), LINK2=(PROG54,...) NATUTM LINK=(PROG1,PROG2,PROG3,PROG4)
With this parameter, a format name for the logoff message can be specified. Possible values are:
Value: | Explanation: |
---|---|
'-END' |
The message defined in the format exit module
FREXIT is
output: NAT9994 - YOUR SESSION WAS SUCCESSFULLY FINISHED. PLEASE GIVE "KDCOFF" (LEAVE THE APPLICATION) OR "UTM-TAC". The message is output in the language specified by parameter
This is the default value. |
' ' |
The following message is output in line mode: NAT9994 - Natural TERMINATED NORMALLY |
'name'
|
The user-defined message is output.
The message is defined with in minus (-) format in
|
'KDCOFF' |
An automatic KDCOFF is performed for the user when
a FIN
system command or TERMINATE statement is
executed.
|
In any case, the operand specified with the
LOFFMAP
parameter is used as the format name for
openUTM. The operand is therefore restricted to a maximum of 8
characters.
This parameter specifies whether the Natural monitor is activated automatically during application startup or not. Possible values are:
Value: | Explanation: |
---|---|
ON |
The Natural monitor is activated automatically during application startup. |
OFF
|
The Natural monitor is not activated automatically during application startup. This is the default value. |
With this parameter, you specify a Natural user thread address. The following happens if you specify a particular value:
Value: | Explanation: |
---|---|
, (comma)
|
Comma means no value. The Natural user thread will be allocated in the next free address below the 16-MB line. This is the default value. |
XXXXX
|
The Natural user thread will be allocated on the hexadecimal
address in the class 6 memory below the 16-MB line. This address must be
aligned to the 4-KB segment limit. The result of address plus Natural user
thread's length in bytes (MAXSIZE )
must not be greater than address H'DF0000' . The highest possible
address is H'DEFFFF' .
|
ABOVE |
The Natural user thread will be allocated above the 16-MB line. |
(ABOVE,NNNNN) |
The Natural user thread will be allocated above the 16-MB line
where NNNNN denotes the decimal number
of megabytes above the 16-MB line.
|
NUAADDR=ABOVE |
The Natural user thread will be allocated in the next free address above the 16-MB line. |
NUAADDR=(ABOVE,258) |
The hexadecimal address of the Natural user thread is
H'10200000' (above the 16-MB line).
|
NUAADDR=6E000I |
The hexadecimal address of the Natural user thread is
H'6E000' (below the 16-MB line).
|
When the Natural user thread is allocated above the 16-MB line, the asynchronous write buffer and the thread for asynchronous transactions will also be allocated above the 16-MB line. In this case, the 31-bit address mode will not be switched back to 24-bit address mode before a 3GL program is called. This means the called 3GL program must be able to run in 31-bit address mode.
This parameter specifies the name of the bounded, reentrant Natural module. Possible values are:
Value: | Explanation: |
---|---|
name
|
The name of the bounded, reentrant Natural module. |
No default value is provided.
You must use the name of the bounded, reentrant Natural module for the
Natural pool and load information in macro
ADDON
(macro
ADDON
assembles BS2STUB
) and for program
CMPSTART
when a shared nucleus is to be used.
This parameter applies to the generation of both the non-reentrant part and the reentrant part. Possible values are:
Value: | Explanation: | ||
---|---|---|---|
nn,loc
|
nn
|
24/31 |
The first value of this parameter
(nn ) is used to define an addressing
mode (24-bit or 31-bit mode) for the Natural openUTM
application.
|
loc
|
BELOW/ABOVE |
The second value of this parameter
(loc ) is used to define the partial
program location of the Natural openUTM application.
|
|
(31,ABOVE) |
This is the default value. |
If you load the environment-dependent nucleus (see the Installation documentation) of the application above 16 MB, this must be defined in the link procedure of the environment-dependent nucleus as follows:
LOADPT=*XS
or
LOADPT=X'address'
/EXEC TSOLINK PROG NATvrs,FILENAM=NATvrs,LOADPT=*XS,... TRAITS RMODE=ANY,AMODE=31 INCLUDE.... /* PARMOD=(nn,loc) MUST ALSO BE DEFINED FOR ASSEMBLING MACRO NURENT, WHICH /* BELONGS TO THE REENTRANT PART OF NATURAL openUTM; OPERANDS MUST BE IDENTICAL FOR /* THE NON-REENTRANT AND REENTRANT PARTS.
where vrs
represents the
current product version.
This parameter defines a openUTM TAC for a PEND
PR
. Possible values are:
Value: | Explanation: |
---|---|
'zzzzzzzz' |
zzzzzzzz (maximum 8
characters) defines the openUTM TAC.
|
' ' |
This is the default value (no TAC for PEND
PR ).
|
When PENDPR='zzzzzzzz'
is
specified, a PEND PR(OGRAM)
is executed instead of a PEND
FI(NISH)
when the FIN
system
command is entered or a TERMINATE
statement is
executed or the PEND PR
function key is pressed. The
openUTM partial program that has been associated with the specified
openUTM TAC is started after the PEND
PR
.
This parameter is used to set one of the following function-key modes:
Value: | Explanation: |
---|---|
(KN, y) |
The literals %K1 to %K20 and send-key
code DÜ are loaded to the function keys.
|
(KO, y) |
The literals 01 to 20 and send-key
code F5 are loaded to the function keys.
|
(KS, y) |
The literals A to T and send-key code
F5 are loaded to the function keys; in addition, with every output
message a dummy field is generated at the last two positions of the screen,
which is used to receive and pass the key value.
|
OFF |
No function key mode is generated. |
KS,L
|
This is the default value. |
Where y
can be:
L |
function keys are loaded |
N |
function keys are not loaded |
This parameter is used to define an openUTM return code for a function key (F1 to F5 or K1 to K14). Possible values are:
Value: | Explanation: |
---|---|
nnZ |
Possible values are 20Z to
39Z .
|
35Z
|
Default value for K10 (keys ESC + >). |
Whenever a function key defined with this parameter is activated in the
Natural dialog, the Natural session is suspended and if an openUTM TAC
for another openUTM partial program is available, a PEND
PR(OGRAM)
is executed.
This openUTM TAC can be defined in several ways:
with the Natural profile parameter
PROGRAM
=tac
,
with the parameter PENDPR
=tac
,
with the utility program TACSWTCH
.
On return from the called openUTM partial program via the
PEND PR(OGRAM)
to the Natural openUTM
Interface, the Natural session is continued at the point where it has been
suspended.
The same return code as specified with the PRKEY
parameter must also be defined with an SFUNC
statement in
KDCDEF
.
This parameter can be used to define an openUTM function key. Possible values are:
REFRKEY=nnZ |
Possible values for nn
are in the range from 26 to 39 (K1 to
K14).
|
REFRKEY=NO |
No openUTM function key defined. |
REFRKEY=39Z |
Default value for K14 (keys ESC + :). |
If the defined function key is pressed, the last full Natural screen is
refreshed. Thus it is possible to continue the dialog with Natural after the
screen has been overwritten by messages from the operator or the operating
system. The send key code is not passed to the Natural application. The
interface sets the Natural key code to ENTER
.
This parameter defines the access method for the Natural roll file. Possible values are:
Value: | Explanation: |
---|---|
UPAM-SY |
The access method for the Natural roll file is
UPAM with synchronous roll file I/Os. This access method is not
allowed with global swap pools.
|
UPAM-AS
|
The access method for the Natural roll file is This is the default value. |
(UPAM-AS,PAMWAIT) |
The Natural openUTM Interface waits with a VPASS
SVC from the completed asynchronous write before a PEND RE
is executed. This option is needed because a openUTM task which is
inactive (P2 wait) cannot be posted via P1-eventing. Instead, the user session
must be terminated with the error message Timeout for asynchronous
write .
|
FASTPAM |
The access method for the Natural roll file is
FASTPAM with Forward Eventing for asynchronous writes (high
performance). See prerequisites described below.
|
To use the FASTPAM
option, the following prerequisites
apply:
BS2000/OSD Version 1.0 or above.
Parameter TERMTAB
must be defined as
SWP
.
The class II definition in the batch job for starting the resident FASTPAM environment and the FASTPAM I/O pool must be:
/EXEC NATUTM,CLASSII=(nnn, yy)
The FASTPAM authorization in the user catalog must be:
/SHOW-USER-ATTRIBUTES FIELD:DMS-TUNING-RESOURCES=*EXCLUSIVE /*OR ALTERNATIVELY: /MODIFY-USER FIELD: DMS-TUNING-RESOURCES=EXCLUSIVE-USE>
The BIAS for the BS2000/OSD operating system must be defined as follows:
/MODIFY-SYSTEM-BIAS MAX-RESIDENT-PAGES=nnn
To calculate the necessary number of resident core pages, use the following formula (ignore all rest values):
ROLLTSZ + 3 / 4 * 2 = N1 (FASTPAM I/O areas) ROLLTSZ + 31 / 32 * 36 + 4095 / 4096 * 2 = N2 (FASTPAM access lists)
N1
+ N2
= number of resident pages for one
Natural openUTM task
This parameter determines the maximum roll thread size nnn (in KB); that is, the maximum size of a compressed user thread on the Natural roll file. Possible values are:
Value: | Explanation: |
---|---|
nnn
|
nnn must be a multiple
of 4 (roll file block size).
|
160
|
This is the default value. |
If ROLLACC
=UPAM-AS
,
valid values for ROLLTSZ
are 4
to
1600
(KB).
If ROLLACC=UPAM-SY
or ROLLACC=FASTPAM
, valid
values for ROLLTSZ
are 4
to
3200
(KB).
To calculate the size of the Natural roll file, use the following formula:
ROLLTSZ
/ 2 * maximum number of users =
nnn
nnn
is the number of PAM pages
for the Natural roll file.
As user threads are generally written to the roll file in compressed form, an optimum roll thread size contributes considerably to saving disc storage.
The optimum value for nnn
can
be ascertained with the Natural Swap Pool Statistics; see the
SYSLST
parameter.
This parameter can be used to control restart situations in which the "lifetime" of a user results from an old Natural openUTM session. Possible values are:
Value: | Explanation: |
---|---|
YES |
In such a restart situation a message is displayed to the user
and the openUTM task is finished with PEND
FI(NISH) ; the user must restart his/her openUTM task by
entering the openUTM TAC.
|
NO
|
In such a restart situation the Natural session is newly initialized without a message being displayed. This is the default value. |
This parameter can be used to control restart situations. Possible values are:
Value: | Explanation: |
---|---|
YES
|
There will be a warm start of a Natural session if there is an openUTM restart situation. The last terminal screen will be displayed, prerequisite for this function is a global Natural swap pool. This is the default value. |
NO |
There will be a restart of a Natural session if there is an openUTM restart situation. |
This parameter can be used to define (one or two) terminal types for which Natural screen optimization is to be de-activated. Possible values are:
Value: | Explanation: |
---|---|
(yy=zz) |
yy must be a valid terminal name
TERMN as defined in KDCDEF .
For terminal types defined in |
(yy=zz
,yy=zz) |
Same as above, but two terminals defined. |
NO
|
Screen optimization is active for all terminal types. This is the default value. |
SCRNOPT=(FL=Z9)
where:
FL |
is a valid TERMN name for IBM 3270-type
terminals
|
Z9 |
is a synonym for 3270-type terminals |
This example would deactivate screen optimization for those 3270-type
terminals which are defined as TERMN=Z9
in
KDCDEF
.
With this parameter, you can specify the name of a user exit. Possible values are:
Value: | Explanation: |
---|---|
name
|
Specifies the name of a user exit. |
SHUTEX1
|
This is the default value. |
This user exit is invoked by the Natural openUTM Interface
whenever an openUTM task is terminated with
KDCSHUT
, provided that the openUTM
SHUTDOWN
function has been defined in KDCDEF
.
With this parameter, you can specify the name of a user exit. Possible values are:
Value: | Explanation: |
---|---|
name
|
Specifies the name of a user exit. |
SHUTEX2
|
This is the default value. |
This user exit is invoked by the Natural under openUTM when
the last openUTM task is terminated with
KDCSHUT
, provided that the openUTM
SHUTDOWN
function has been defined in KDCROOT
.
This parameter enables you to specify a spooling system. Possible values are:
Value: | Explanation: |
(NATSPOOL,'enter-parms ',
n) |
For use with NATSPOOL (Natural Advanced Facilities), see
Using
NATSPOOL.
|
REPRO-2000 |
For use with a remote spooling system, see Using REPRO-2000 Remote Spooling System. |
RMSPOOL |
For use with your own user exit program, see Using RMSPOOL User Exit. |
No default value is provided
The following topics are covered below:
When using NATSPOOL
(Natural Advanced Facilities), the
SPOOL
parameter can be used to indicate that the printer
task(s) required by NATSPOOL
are to be started up automatically by
means of ENTER
calls whenever the Natural openUTM
application is started, and terminated whenever the application is shut down.
In this case, the operands of the parameter must be:
SPOOL=(NATSPOOL,'enter-parm',n)
where:
'enter-parms' |
are the parameters for the ENTER call (in
apostrophes)
|
n |
is the number of printer tasks to be started (in the range 1 to 30) |
The following ENTER
job is to be automatically started
and terminated. The file name is AF.E.PRINT
:
/LOGON /OPTION MSG=FHL /SYSFILE FILE=SYSLST /EXEC NAFPTTSK /LOGOFF
Operand definition for the parameter SPOOL
:
SPOOL=(NATSPOOL,'AF.E.PRINT,TIME=999',2)
In this example, NATSPOOL
is the name of the Natural
spooling system; AF.E.PRINT
is the file name of the
ENTER
job to be started and terminated; TIME=999
is
an additional, optional parameter for the ENTER
call (see the
description of the BS2000/OSD ENTER
macro); and 2
means that two NATSPOOL
printer tasks are to be
started/terminated.
The second suboperand can contain any valid operands (enclosed in
apostrophes) for the ENTER
macro call.
The operand of parameter SPOOL
in macro
NURENT
must be NATSPOOL
.
The specified number of NATSPOOL
printer tasks according
to the operand definition in the parameter SPOOL
is
started when the application is started up. Interprocess communication is then
used to check that at least one printer task is running. If this condition is
not satisfied, the application is set to status SYSTEMERROR
, an
error message is output on the console and users who attempt to logon are
rejected with the message:
NUI0036 - SYSTEMERROR ... PLEASE GIVE KDCOFF
For more information on this system error, see error message NUI0036.
If a remote spooling system is used (for example, TD-SPOOL or
REPRO-2000), set SPOOL=REPRO-2000
in the macros
NATUTM
and
NURENT
. This function

The logic used by Natural offline reports must be considered when
implementing the interface module for a remote spooling system (see macro
NURENT
, label CMWHC
). When an offline report is
activated, Natural transfers output a record at a time. The logic for sending
and accepting print records, the layout of the print record, etc., are in macro
NURENT
, subroutine CMWHC
.
If you use your own user exit program named RMSPOOL
as
remote spooling interface, set SPOOL=RMSPOOL
in the macros
NATUTM
and NURENT
. See
User Exits for
details on the user exit RMSPOOL
.
With this parameter, you can specify the name of a user exit. This user exit is invoked by Natural under openUTM whenever a openUTM task is started. Possible values are:
Value: | Explanation: |
---|---|
name
|
Specifies the name of a user exit. |
STARTEX
|
This is the default value. |
With this parameter, you can specify the name of a user exit. This user
exit is invoked by Natural under openUTM when the first
openUTM task is started, provided that the openUTM
STARTUP
function has been defined in KDCDEF
. Possible
values are:
Value: | Explanation: |
---|---|
name
|
Specifies the name of a user exit. |
STAPPLX
|
This is the default value. |
This parameter determines the length in bytes of a save area for dynamic Natural parameters in the openUTM KB. These parameters are used when a Natural openUTM session is restarted. Possible values are:
Value: | Explanation: |
---|---|
nnnn
|
Specifies the length in bytes of a save area for dynamic
Natural parameters in the openUTM KB. Possible values are
0/8...2048 (bytes).
|
0
|
This is the default value. |
This parameter determines whether a 31-bit address mode is switched to
24-bit mode or not before a PEND PR
is executed.
What you must set depends on whether the partial openUTM program can
run in 31-bit address mode (NO
) or not (YES
).
Possible values are:
Value: | Explanation: |
---|---|
YES |
31-bit address mode is switched to 24-bit mode. |
NO
|
This is the default value. |
This parameter determines whether the swap pool main directory is pageable or not. Possible values are:
Value: | Explanation: |
---|---|
NO |
Specifies that the swap pool main directory is not pageable. |
YES
|
This is the default value. |
A swap pool directory that is not pageable improves performance
considerably. In that case, the BS2000/OSD macro CSTAT
will be
used to declare the swap pool directory as not pageable. To be able to specify
SWDPAGE=NO
, you must define the maximum and minimum of resident
core pages in the startup job.
/EXEC E.NATvrs,CLASSII=(4,2)
where vrs
represents the
current product version.
For more information, see the description of BS2000/OSD macro
CSTAT
or the description of BS2000/OSD command
EXECUTE
, operand CLASSII
or, when SDF
is used, the description of BS2000/OSD command
START-PROGRAM
, operand
RESIDENT-PAGES=PARAMETERS...
If the call to macro CSTAT
fails, the application is still
able to run.

with parameter MULTI-SIGNON=YES
is
set;
UPIC
or terminal server clients are defined in an LTERM
pool (TPOOL) with CONNECT-MODE=MULTI
set.
In both cases, KCBENID
might not be unique and thus not
suitable as swap pool user identification.
With this parameter, you can specify the name of the logical
openUTM communications partner (as defined in KDCDEF
) of
the synchronous openUTM application. Possible values are:
Value: | Explanation: |
---|---|

Specifies the openUTM transaction code. |
NATSY
|
This is the default value (synchronous TAC). |
The openUTM TAC specified in this parameter must be distinct from the "standard" Natural TAC and also from the TAC used for the asynchronous openUTM application.
This parameter defines whether a SYSLST

This parameter defines the action to be taken in conjunction with the
openUTM operation key PEND
. Possible values
are:
Value: | Explanation: |
---|---|
KP |
Each dialog step is terminated with a PEND KP
(KEEP ). The openUTM KB is written to the page pool of
KDCFILE only if no additional space in openUTM cache
storage is available. It is to be noted that no synchronized processing between
openUTM(s) and Adabas can be performed.
|

This parameter defines the terminal control table needed to manage the Natural roll file. Possible values are:
Value: | Explanation: |
---|---|
|
20 bytes long 12 bytes 10 bytes 2 bytes 10 bytes 2 bytes See Explanation of Operands below. |
(SWP,TERMNAME) |
This is the default value. |
The terminal control table is allocated either in the Natural swap pool
or in the Natural roll file. It contains a header (48 bytes) and an entry for
each active user or active session. Its size depends on the size of the Natural
roll file, on the value of the parameter ROLLTSZ
and on the length
of its own entries.
The Natural openUTM Interface computes the length of the terminal control table as follows:
Roll file pages / (ROLLTSZ / 2) = N
N * terminal control table entry length + 48 = length of the terminal control table
Operand | Meaning |
---|---|
SWP |
The terminal control table is allocated in the Natural swap pool. |
TERMNAME |
The logical terminal name will be used to identify an entry in the terminal control table. |
INTERNID |
The internal terminal ID (serial number) will be used to
identify an entry in the terminal control table. INTERNID is two
bytes long.
|
CHECKPNT |
Is only allowed when the terminal control table is allocated in
the Natural swap pool. It is necessary if terminals are defined with
|
N |
The number of PAM pages for the terminal control table in the
Natural roll file. Possible values of this operand are 1 to
16 (PAM pages). For each terminal, 10 bytes are needed in the
terminal control table. For each session, two bytes are needed.
|

TERMTAB=(1,INTERNID)
The maximum number of entries in the terminal control table: 1 * 2048 - 48 / 2 = 1000
This parameter specifies the method to be used to construct the "unique" Adabas user ID. Possible values are:
Value: | Explanation: | ||
---|---|---|---|
n
|
The Adabas user ID is constructed from the defined
(n ) character of the operand of the
parameter APPLNAM (default
value: N ) and the last two characters of the user's first
SWAPPAMKEY . n must be a number in the
range of 1 to 8.
|
||
(T, n) |
A unique 4-byte user ID is constructed by taking characters
n to (max.
n +3 ) of the logical openUTM
terminal name (KCLOGTER ).
n must be a number in the range 1
- 8 . The resulting character string must consist of valid characters
(0 - 9 and A - F ) and must be unique. See example
below.
|
||
(U, n) |
The characters are taken from the openUTM user ID
(KCBENID ), starting at the position specified by the second
subparameter. The resulting character string must consist of valid characters
and must be unique.
|
||
(TID=1) |
The Adabas user ID consists of the first digit from the operand of
parameter This is the default value. |
Example:
TID=(T,4)
KCLOGTER
|
Adabas User ID | |
---|---|---|
1st terminal | LTU9A110 |
X'00009A11' |
2nd terminal | LTU9F110 |
X'00009F11' |
3rd terminal | LTU9F120 |
X'00009F12' |
If "mixed" Adabas calls occur within one Natural
openUTM application (that is, calls from both Natural and non-Natural
programs), the Adabas user ID can be found using the ENTRY CMTRMID
in macro NATUTM
. The current Adabas user ID (4 bytes) can be found
at address CMTRMID
; see also the parameter
ADACALL
.
EXTRN CMTRMID . . L R1,CMTRMID MVC ADAID(4),0(R1)
For the Adabas user ID, the full terminal name (KCLOGTER
)
will be used when TID=(T, n)
or the
full user ID (KCBENID
) will be used when
TID=(U,n)
. Default is
TID=((T,1)
.

SYSLST nn trace file. Possible range:
01 -99 .
ll is the maximal length in characters
of a trace print record. Possible range: |
(99,71)
|
This is the default value. |
If any external Natural trace function is active, the trace records
will be written to SYSLST nn
. In this
case, the Natural openUTM driver creates the following trace file:
applname.Natural.TRACE,SPACE=(90,60) SYSFILE SYSLSTnn=applname.Natural.TRACE /* applname is the application name
This file will be used by all tasks of the Natural openUTM application. Before the Natural openUTM application is terminated, the trace file will be closed as follows:
SYSFILE SYSLSTnn=(PRIMARY)
To activate the Natural trace functions, see the parameters
ETRACE
and ITRACE
of the
Natural parameter module.

One fullword is available for user-defined purposes in the Natural swap
pool directory - see label USERWRD
in DSECT MEMPOOL
of macro NAMSWDIR
. This word can be used for synchronization, for
example, for switching accounting on and off, whilst the Natural
openUTM application is running.
The following example shows how this area can be addressed.
