IMSP - General Parameters for Natural IMS TM Interface

This Natural profile parameter can only be specified with the NTIMSP macro, dynamic parameter specification is not possible yet.

The NTIMSP macro is used to set general parameters for the Natural IMS TM Interface.

The NTIMSP macro can be specified only once in the Natural parameter module.

Possible settings	See below.
Default setting	See below.
Dynamic specification	no
Specification within session	no

NTIMSP Macro Syntax

The NTIMSP macro is specified as follows:

         NTIMSP NIINAME=value,                                         *
               SUBPOOL=value,                                          *
               THRELO=value,                                           *
               TRNCODE=value

See Keyword Subparameters.

Keyword Subparameters

NIINAME | SUBPOOL | THRELO | TRNCODE

NIINAME - Natural IMS TM Interface Module Name

NIINAME=value specifies the name of the Natural IMS TM Interface module to be used by the current driver.

Value	Explanation
1- 8 characters	A valid module name.
`NIIINTFM`	This is the default value.

SUBPOOL - Storage Subpool

SUBPOOL=value specifies the z/OS subpool to be used for storage requests.

Value	Explanation
`0 - 127`	The number of a z/OS task-related subpool used by a problem state program.
`125`	This is the default value.

THRELO - Thread Relocation

THRELO=value determines whether the Natural storage thread can be allocated at a different virtual address after a terminal I/O.

Value Explanation

Value	Explanation
`ON`	Thread relocation is enabled: the Natural thread can be allocated at a different virtual address after a terminal I/O. This is the default value.
`OFF`	Thread relocation is disabled and the Natural thread remains at the same virtual address. The size of the Natural thread is determined by the first Natural session that allocates the thread. As a consequence: the `THSIZE` keyword subparameter (`NTIMSPE` macro) is ignored except for the first Natural session in an MPP environment, the `RELO` profile parameter is ignored, and the storage for the Natural thread remains allocated until the MPP environment is stopped. Note: We recommend that you only set `THRELO=OFF` if you use Con-form.

ON

Thread relocation is enabled: the Natural thread can be allocated at a different virtual address after a terminal I/O.

This is the default value.

OFF

Thread relocation is disabled and the Natural thread remains at the same virtual address.

The size of the Natural thread is determined by the first Natural session that allocates the thread. As a consequence:

the THSIZE keyword subparameter (NTIMSPE macro) is ignored except for the first Natural session in an MPP environment,
the RELO profile parameter is ignored, and
the storage for the Natural thread remains allocated until the MPP environment is stopped.

Note:
We recommend that you only set THRELO=OFF if you use Con-form.

TRNCODE - Identify Transaction Code

TRNCODE=value can be used to identify the transaction code.

Value	Explanation
`ON`	The `TRNCODE` keyword subparameter is activated to evaluate the `TRNCODE` parameter: on the first card of the BPM `CONTROL` file, in the `NIMBOOT` macro, used as the startup parameter of the server environment.
`OFF`	The `TRNCODE` keyword subparameter is deactivated. This is the default value.

Example of NTIMSP Macro

         NTIMSP NIINAME=NATIMS1,SUBPOOL=0
