This Natural profile parameter specifies information concerning the physical database file to be associated with a logical system file for Software AG products.
It can be used for Software AG products which have their own system files
(for example, Con-nect and Natural Elite) to specify where such a system file
is to be located. Such products use Database ID 255 and a logical
file number (FNR) in their data definition modules (DDMs). With the
LFILE parameter, you specify which physical database ID
(DBID) and file number (and, if applicable, password and cipher key) are
associated with that logical file number.
Natural records the physical file information and uses it for any
database calls to Database ID=255 and File
number=logical-ID.
| Possible settings | logical-FNR |
1 - 251 |
Logical file number (LFL). This parameter is mandatory. |
|---|---|---|---|
physical-DBID |
0 - 65535, except
255 |
Physical database ID (DBID). Database ID
255 is reserved for logical system files for Software AG products.

physical-FNR |
1 -
5000 |
Physical file number (FNR). | |

Must be a setting of 1 to 8 characters. * | ||

Must be a setting of 1 - 8 numeric digits.

* Password and cipher key are only required if the database file has been
password-protected and/or ciphered using the Adabas security feature.
With FDDM, FNAT and
FUSER, the password and the cipher key are reserved for future
use; currently they are ignored.
To define different logical files, the LFILE
parameter
must be specified several times.
The following topics are covered below:
The LFILE parameter is specified as follows:
| LFILE=(logical-FNR,physical-DBID,physical-FNR,password,cipher-key,RO) |
LFILE=(180,73,10),LFILE=(251,40,9,TEST99)
