This Natural profile parameter can be used to define database types
and options for all and for specific database IDs. It corresponds to the
NTDB
macro in
the Natural
parameter module.
Possible settings | See DB Parameter Syntax. | |
---|---|---|
Default setting | ADABAS,* |
The default database type is Adabas. |
Dynamic specification | yes | This parameter can only be specified dynamically. In the
Natural
parameter module, the macro
NTDB is used
instead.
|
Specification within session | no |
Notes:
The following topics are covered below:
The DB parameter is specified as follows:
The default database type and its default options is specified as
follows. It applies to all database IDs not explicitly specified by the
DB
parameter or
NTDB
macro.
If there are no options, the commas and the asterisk can be omitted.
DB=(database-type,*,options) |
A single database ID is specified as follows:
DB=(database-type,database-ID,options) |
Multiple database IDs of the same database type with the same options can be specified together, enclosed in parentheses:
DB=(database-type,(database-ID1,database-ID2,...),options) |
Where:

Database identification.
Database ID You can specify a single database ID, a list of database IDs enclosed in parentheses, or an asterisk (*) to indicate the default for all databases not specified explicitly. |

The NTDB
macro is specified as follows:
The default database type and its default options is specified as
follows. It applies to all database IDs not explicitly specified by the DB
parameter or NTDB
macro. If there are no options, the commas and
the asterisk can be omitted.
NTDB database-type,*,options
A single database ID is specified as follows:
NTDB database-type,database-ID,options
Multiple database IDs of the same database type with the same options can be specified together, enclosed in parentheses:
NTDB database-type,(database-ID1,database-ID2,...),options
The database types that can be specified with the
DB
parameter or the NTDB
macro
are listed in the following table.
A database type and version for Adabas indicates the functional level of database features that are to be used by Natural.
All database types except Adabas require that the appropriate database handler module is installed. For more information, see the appropriate documentation about the database handler required in your environment.
Database Type | Adabas Features or Database Handler to be Used |
---|---|
ADABAS
or
|
Adabas Version 8.2 features
|
ADAV7
|
Adabas Version 7 features |
ADAV8 |
Adabas Version 8 features |
VSAM |
Natural for VSAM |
DLI |
Natural for DL/I |
DB2

The following options can be specified with the
DB
parameter or the NTDB
macro:
Option | Explanation |
---|---|
ACODE |
The Natural application must
communicate to Adabas whether code page or Unicode support is desired if the
Adabas DBID used is enabled for character encoding and data conversion.
Therefore, the ACODE setting specifying the application-specific
code page for all A fields and/or the WCODE=4095 (UTF-16) setting
for all W fields must be sent with the OP call. See also
Unicode and
Code Page Support.
|
WCODE |
|
ENTIRE |
The database is to be handled by Entire DB. |
OPEN |
This option applies to Adabas databases
only, for which Adabas requires an open request to be issued. If
OPEN is specified for such a database, an open request is always
issued (even if the ETID is blank).
|
READ |
The database is to be read-only. |
The following options can be specified with the dynamic parameter
DB
only.
Option | Explanation |
---|---|
NOENTIRE |
Resets the ENTIRE
option.
|
NOOPEN |
Resets the OPEN
option.
|
NOREAD |
Resets the READ
option.
|
OFF |
Removes any DB or
NTDB definition for the specified databases, see
Examples of DB
Parameter below.
|
DB=(VSAM,(22,26,33)) |
This defines Databases 22, 26 and 33 as VSAM databases. |
DB=(,*,READ) |
This sets all databases for which the default database definition applies to read-only. |
DB=(,(8,9),NOREAD) |
This removes the read-only option for Databases 8 and 9. |
DB=(,17,OFF) |
This resets the database definition of Database 17 to defaults. |
NTDB DLI,7 |
This defines Database 7 as DL/I database. |
