Natural under IMS TM - Configuration

The main parameter required to configure the Natural IMS TM Interface are specified with the following profile parameter macros of the Natural parameter module:

  • NTIMSP for general parameter settings,

  • NTIMSPE for specification of environment-specific parameter sets, and

  • NTIMSPT for transaction code definitions.

Important
You must at least specify the NTIMSPT macro and define individual parameters for your Natural IMS TM transactions (there are no default values).

In addition to the Natural parameter macros, you can use the optional macros described in the following section. They are provided by the Natural IMS TM Interface.

NIMMSGT Macro Parameters

The macro NIMMSGT generates each entry in the message text module NIIMSGT which is part of the Natural IMS TM Interface module. Each generated entry provides a message text for each possible Natural IMS TM error number.

The NIMMSGT macro is specified in one of the following two ways: 

Nerror-number [*] NIMMSGT  message-text

In this case, Natural under IMS TM will display the message text as defined. The message text may be up to 72 characters long. 

Xerror-number [*] NIMMSGT message-text

In this case, Natural under IMS TM will append an error-specific reason code to the current message text. The message text may be up to 64 characters long.

If the error number is followed by an asterisk (*), a snap dump will be generated when an error occurs. You may adapt the message text to your own requirements. You may also add or delete the DUMP option of a specific error number. You must not modify the error number and the characters N or R that precede the error number.

NIMPIXT Macro Parameters

The NIMPIXT macro generates the Physical Input Edit Routine.

The parameters which can be specified with the macro NIMPIXT are listed in alphabetical order below:

PIXTE | SIPSE | SPATID | WTO | USER

Parameter Possible Value Description Default Comment
PIXTE 1 - 999 Specifies the start value for error numbers if errors are detected by the physical input edit routine. 400 This value is added to the return code set by the physical input edit routine. The result is the IMS TM error message number in the user message table DFSCMTU0.
SIPSE 1 - 999 Specifies the start value for error numbers if errors are detected by the Authorized Services Manager. 500 This value is added to the return code set by the Authorized Services Manager. The result is the IMS TM error message number in the user message table DFSCMTU0.
SPATID xxxx Specifies the Natural subsystem ID for the Authorized Services Manager which is used to save the SPA for the non-conversational driver. Any string up to 4 characters is possible. None The value of this parameter must be the same as the value specified for the SPATID keyword subparameter in the NTIMSPE macro (Natural parameter module).
WTO YES Specifies whether a WTO message is issued if the Authorized Services Manager fails. NO None.
NO
USER xxxxxxxx

Specifies whether a user-specific physical input edit routine is to be called if the NIMPIXT macro does not find the SPA.

If a user-specific input edit routine is to be called, specify the name of the routine.

NO None.
NO

NIMBOOT Macro Parameters

The macro NIMBOOT generates the bootstrap module used by the message-oriented environment or the server call interface used by the server environment.

NIMBOOT includes the following parameters:

TYPE | DRIVERN | ENVTNAM | TRNCODE | DYNPARM | SERVERN

Parameter Possible Values Default Comment
TYPE SERVER Empty TYPE specifies the type of the interface module to be generated.

With TYPE=SERVER, the server call interface NIIBOOTS is generated.

Empty If nothing is specified, the bootstrap module used by the message-oriented environment is generated.
DRIVERN Any valid z/OS module name None

This parameter specifies the name of the front-end module.

If TYPE=SERVER is specified, the front-end module must have been generated for the server environment. If no TYPE is specified the front-end module must have been generated for the message-oriented environment.

ENVTNAM Any valid z/OS module name None

This parameter is only used by the bootstrap module for the message-oriented environment (TYPE is empty).

This parameter specifies the name of the environment table. This parameter is optional. If it is not specified, the environment table is determined by the entry in the transaction code table which corresponds to the transaction code used.

TRNCODE    

This parameter is only used by the bootstrap module for the message-oriented environment (TYPE is empty).

This parameter specifies the name of the transaction code which is internally used by the Natural IMS TM Interface. This parameter is optional and is only honored if TRNCODE=ON is specified in the NTIMSP macro (Natural parameter module). If it is not specified or if TRNCODE=ON is specified in the NTIMSP macro, the transaction code returned by the IMS TM INQY call is used.

The transaction code is used to determine the entry in the transaction code table.

DYNPARM Any character string of up to 80 characters. None

This parameter is only used by the bootstrap module for the message-oriented environment (TYPE is empty).

This parameter is used to define a valid string of up to 80 characters of Natural dynamic parameters.

SERVERN Any valid z/OS module name NIIBOOTS This parameter is only used by the server call interface (TYPE=SERVER).

This parameter specifies the name of the server environment. It is only relevant if you want to use several Natural servers in the same region. In this case, you must generate multiple server call interfaces and specify a unique name with SERVERN for each of them. See Special Functions, Server Environment.
