This Natural profile parameter is used to specify five subparameters for the Natural system file for DDMs.
If this system file is defined, all DDMs are stored on the specified
path. DDMs stored in libraries will no longer be accessible from Natural. This
is similar to Natural on mainframes, where all DDMs are stored in the system
file FDIC.
If the FDDM system file is undefined (database-ID and file-number = 0), the DDMs are stored in the libraries as supplied before. The system file FDDM is displayed as an inactive environment.
For information on system files, refer to: System Files in the Natural Operations documentation.
| Possible settings | database-ID |
1 - 254 |
Database ID 255 is reserved for
logical system files for Software AG products, see Natural profile parameter
LFILE.
|
|---|---|---|---|
file-number |
1 - 255 |
File number. | |
| password | 1 - 8 characters |
The password is only required if the Natural user-program system file has been password-protected using the Adabas security feature. The password is reserved for future use; currently, it is ignored. |
|
| cipher key | 1 - 8 numeric digits |
The cipher key is only required if the Natural user-program system file has been ciphered using the Adabas security feature. The cipher key is reserved for future use; currently, it is ignored. |
|
| RO | Indicates that the Natural user-program system file is "read-only" and is only specified if modifications on the file are to be disabled. | ||
| Default setting | none | ||
| Dynamic specification | yes | ||
| Specification within session | no | ||
The syntax of this parameter is:
| FDDM=(database-ID,file-number,password,cipher-key,RO) |
FDDM=(22,5) FDDM=(22,5,,12345) FDDM=(22,5,,,RO)
