Caution:
This parameter applies to user files only. It does not apply to
system files.
This Natural profile parameter can be used to translate a database
ID/file number to another database ID/file number during the execution of an
application. It corresponds to the macro NTTF in the
parameter module NATPARM.
| Possible settings | production-DBID |
Must be in the range of 0-254, or
256-65535, or can be an asterisk (*) which stands for all DBIDs.
Database ID 255 is reserved for logical system files for Software
AG products, see profile parameter LFILE.
|
|---|---|---|
| production-FNR | Must be in the range of 1-65535, or an asterisk (*)
which stands for all FNRs.
|
|
| test-DBID | Must be in the range of 0-254, or
256-65535, or can be an asterisk (*) which leaves the DBID
unchanged.
|
|
| test-FNR | Must be in the range of 1- 65535, or an asterisk
(*) which leaves the FNR unchanged.
|
|
| Default setting | none | |
| Dynamic specification | yes | This parameter can only be specified dynamically. In the Natural
parameter module NATPARM, the macro
NTTF must be used instead.

This feature is relevant when developing an application in a production
environment. It enables you to develop an application in a test database and
then transfer the finished application to the production database without
having to change or re-compile the application.The Natural objects are
cataloged with the production DBID/FNR, but whenever a database access is
executed, the production DBID/FNR is translated into the test DBID/FNR
according to the TF parameter specifications; that is,
the test database is used. This means that testing can take place in the actual
production environment, but not with production data.
The TF parameter or the
NTTF macro can be specified several times so as to
specify different combinations of file numbers.
The following topics are covered below:
The TF profile parameter is specified as follows:
| TF=(production-DBID,production-FNR,test-DBID,test-FNR) |
The NTTF macro is specified as follows:
| NTTF production-DBID,production-FNR,test-DBID,test-FNR |
TF=(777,39,17,88),TF=(251,*,9,*)
Equivalent specification in the Natural parameter module:
NTTF 777,39,17,88 NTTF 251,*,9,*
