This Natural profile parameter specifies information concerning the physical database file to be associated with a logical system file for Software AG products.

LFILE
and
NTLFILE
can be used for Software AG products
which have their own system files (for example, Con-nect, Natural Review) to
specify where such a system file is to be located. Such products use the
database ID 255 and a logical file
number in their data definition modules (DDMs). With the
LFILE
parameter or the macro
NTLFILE
, you specify which
physical file number and
database ID (and, if
applicable, password and cipher key) are associated with that logical file
number. Natural maps the logical file number to the physical file number and
database ID and uses it for any database calls.
LFILE
is especially useful for defining a
scratch-pad file with the logical file number 212; see also the profile
parameter ROSY
,
Natural Scratch-Pad File in the
Operations documentation, and Defining a
Scratch-Pad File in the
Installation for z/OS,
Installation for BS2000 and Installation for
z/VSE documentation.
The following topics are covered below:
The LFILE
parameter is specified as follows:
LFILE=(logical-fnr,physical-dbid,physical-fnr,password,cipher-key,[RO]) |
Where:
Note:
To define different logical files, the LFILE
parameter must be specified multiple times (separated by a comma or a blank);
see Example of LFILE
Parameter.
The NTLFILE
macro is specified as follows:
NTLFILE logical-fnr,physical-dbid,physical-fnr,password,cipher-key,RO
Notes:
LFILE
parameter or the NTLFILE
macro must be specified several
times; see Examples
of NTLFILE Macro.
