This section describes how to customize the default behavior of Natural Business Services. The following topics are covered:
This section describes how the Natural Business Services wizards create names for the Natural objects they generate and how to include your own naming conventions.
Since one Natural Business Services wizard may generate several different Natural objects, each type of object must be uniquely identified. For example, the Business Service wizard creates at least one subprogram that handles logic and one subprogram proxy.
The different styles and their unique identifiers are stored in an LDA called WTRNAMEL. Natural Business Services names the modules as follows:
One character for the object style and one character for the category
To change these characters, modify WTRNAMCL and then recompile CTENAMEL and WTRNAME.
Five characters supplied by you
Optionally, a number to help retain uniqueness within a library
How the unique identifier is used, where it is used, and how unique Natural object names are derived is handled in WTRNAME. To change the location of the category, style, and/or five characters, modify WTRNAME and then test the generation of the Natural module names.
To test the generation of Natural module names:
Enter the "menu D A GU" direct command.
The General Utility Subprograms menu is displayed. For example:
CTEMENGU ***** Natural Construct ***** CTEMNM0

The following screen is displayed. For example:
Up to 5 characters TEST_
(blank searches *LIBRARY, 1 searches provided library,2 searches both)
Provided library: ________ _ Library search requirement:
When a subprogram proxy client is generated,
the name is derived from the server subprogram proxy name.
Since this name is larger than 5 characters, the Name field
is used for input and output. To obtain the client proxy name,
enter the server proxy name in the Name field.
Name: ________
|
By default, TEST is used for the example. Change the default characters and specify the name of the library (if not the current library).
To search the current library, leave the Provided library and Library search requirement fields blank.
To search the Provided library, type the library name in Provided library and type "1" in the Library search requirement field.
To search both libraries, type the library name in Provided library and type "2" in the Library search requirement field.
Enter the name of the server proxy in Name.
Natural Business Services displays the default name of the client proxy. For example, if you entered "MYPROXY" in Name, the following is displayed:
13-10-21 - Driver for subprogram WTRNAME - 17:45:40
You can customize WTRNAMCL, along with WTRNAME, for site-specific
naming conventions.
Names within a category must be UNIQUE
as well as names ACROSS all object maint and object browse modules
Given a server proxy name of: MYPROXY
The client proxy name will be: MYPROXC

You can define default parameter values for the model specification panels in Natural Construct. The supplied models retrieve many of the default values by issuing a CALLNAT to the CSUDEFLT subprogram. Prior to returning the defaults, CSUDEFLT determines whether the values have been overridden by the user-defined CSXDEFLT sample exit subprogram. If so, the overridden values are returned to the model. When the Business Service wizard generates the models to create business services, your default values will be used.
The CSXDEFLT sample exit subprogram provides user-defined default values for model parameters that can be overridden on the specification panels, as well as internal model parameters that are not displayed on the panels.
Note:
For more information, see
Define
Default Specifications.
The CSXSECX sample exit subprogram allows you to take advantage of Natural Security LOGON user exit. If the security routines in CSXSECX are defined and the object code is in the SYSLIBS library, they are processed before the standard Natural Business Services security routines are processed.
The parameters for CSXSECX are:
1 STEPLIB-DATA (A144) 1 REDEFINE STEPLIB-DATA 2 STEPLIB-DATA-STRUCT (1:8) 3 LIB-NAME (A8) 3 LIB-DBID (N5) 3 LIB-FNR (N5) 1 PROXY-SUBPROGRAM (A8) 1 USER-ID (A32) 1 REDEFINE USER-ID 2 USER-ID-A8 (A8) 1 DOMAIN (A8) /* Domain name 1 BUSINESS-SERVICE (A32) /* business service name 1 BUSINESS-SERVICE-VERSION (N6) /* business service version 1 BUSINESS-METHOD (A32) /* business service version
Note:
Although the parameters above are accessible within this exit, you
cannot change the parameter values here; you can only add additional security
verifications.
To customize CSXSECX:
Copy the subprogram from the SYSCSTX library to the SYSCST library.
Add your own security settings.
Stow the subprogram.
Move the object code to the SYSLIBS library to make the routine active.
When the dispatcher is started, it determines whether the object code for CSXSECX is in the SYSLIBS library. If the object code is not in the SYSLIBS library, the dispatcher assumes there is no customized security verification and will process the standard Natural Business Service security routines. If the object code is in the SYSLIBS library, the dispatcher will execute this code first and then process the standard security routines.
For information on the sample exit subprograms, see Access and Use the Sample Exit Subprograms.
Note:
You can also enhance the standard Natural Business
Services security routines. For information, see
Setting Business
Service Security Options.
The CSXTRANS sample exit subprogram allows you to issue BACKOUT or END TRANSACTION statements. If the object code for CSXTRANS is in the SYSLIBS library, it is executed after the call to a business service has been made.
Note:
An Object Maint-generated subprogram issues an END TRANSACTION
statement when CDAOBJ2. #ET-IF-SUCCESSFUL is True. Therefore, a BACKOUT
TRANSACTION statement may not be issued when expected.
The parameters for CSXTRANS are:
1 STEPLIB-DATA (A144) 1 REDEFINE STEPLIB-DATA 2 STEPLIB-DATA-STRUCT (1:8) 3 LIB-NAME (A8) 3 LIB-DBID (N5) 3 LIB-FNR (N5) 1 PROXY-SUBPROGRAM (A8) 1 USER-ID (A32) 1 REDEFINE USER-ID 2 USER-ID-A8 (A8) 1 DOMAIN (A8) /* Domain name 1 BUSINESS-SERVICE (A32) /* business service name 1 BUSINESS-SERVICE-VERSION (N6) /* business service version 1 BUSINESS-METHOD (A32) /* business service version 1 START-OF-PROXY-TIMESTAMP (B8) /* time CALLNAT to business service was issued **SAG END-EXIT PARAMETER USING CDPDA-M
Note:
Changing any value except the values in CDPDA-M will have no effect;
the values are reset to the values they were before entering this exit.
To customize CSXTRANS:
Copy the subprogram from the SYSCSTX library to the SYSCST library.
Add your own BACKOUT or END TRANSACTION logic.
Stow the subprogram.
Move the object code to the SYSLIBS library to make the routine active.
When the dispatcher is started, it determines whether the object code for CSXTRANS is in the SYSLIBS library. If the object code is not in the SYSLIBS library, the dispatcher assumes there is no customized END or BACKOUT TRANSACTION processing and will process the standard Natural Business Service security routines. If the object code is in the SYSLIBS library, the dispatcher will execute this code first and then process the standard security routines.
For information on the sample exit subprograms, see Access and Use the Sample Exit Subprograms.
Note:
You can also enhance the standard Natural Business
Services security routines. For information, see
Setting Business
Service Security Options.
You can customize the business services generated by the Business Service wizard by modifying the Natural Construct generation models. You can modify the code frames, subprograms, and copycode used by the supplied models, as well as the external data areas and subprograms.

Modifying the
Supplied Models.
