This statement describes the physical access path for distributed databases.
Function
The SESDCN control statement ADD-NETWORK-LINK-LIST describes the network for the databases entered in the distribution rule. It assigns the access paths in the network to the logical link names of the databases.
You use this statement to define the access path for all databases entered in the distribution rule that are not in the home configuration. You specify the computer on which the relevant databases are stored, which remote DCN is responsible for forwarding requests in the case of remote access, and which configuration the remote DCN belongs to.
A corresponding entry in the ADD-NETWORK-LINK-LIST statement is not necessary for databases in the home configuration.
You can enter the ADD-NETWORK-LINK-LIST statement once or several times. Together with the entries created implicitly by SESAM/SQL (see the note on "Entering SESDCN control statements") the distribution rule may contain a maximum of 340 entries. You can, however, explicitly enter at least 300 databases and their associated networks.

Operands
LINK-NAME-1 =
First entry of the network access path of a database in the distribution rule. A network access path must be entered for all databases that are not in the home configuration. The home configuration is the configuration in which this SESDCN is started.The network access path consists of the name of the computer on which the database is stored and the configuration name and DCN name of the associated remote DCN. The remote DCN belongs to the same configuration to which the database is assigned. It forwards remote accesses of the database, i.e. accesses from application programs belonging to a different configuration: the configuration of the SESDCN to be loaded, for example.
LINK-NAME-1 = *NONE
This is the default. No other network access path is entered.
LINK-NAME-1 = <name 1..8>(...)
Logical link name that provides the logical link to the associated entry or entries in the ADD-DISTRIBUTION-RULE-LIST statement (see "ADD-DISTRIBUTION-RULE-LIST").
The logical link name specifies for which database in the distribution rule the network access path is to be entered. This name provides the link to the associated remote DCN.
PROCESSOR-NAME = <name 1..8>
Symbolic device name of the computer on which the database is stored and on which the associated remote DCN must be loaded.
CONFIGURATION-NAME = *BLANK / <alphanum-name 1..1>
Configuration name of the configuration to which the remote DCN is assigned. The default is a blank.
DCN-NAME = *BLANK / <alphanum-name 1..1>
Name of the remote DCN.
The default is a blank.
.
LINK-NAME-n =
n = 2-200
nth entry of the network access path of a database in the distribution rule. Up to 200 entries are permitted.
The parameters of this operand are identical to those of the LINK-NAME-1 operand described above.
