LINCS Features

DLUR Configuration and Management
Configuration - In order to use DLUR, you must enable APPN as described in the Configuration
and Management section. The panels which contain DLUR configuration items are:
• The SNA Options panel allows you to define the DLUS (Dependant LU Server).
• If APPN will be used to route data to dependent LUs associated with one or more PUs on
the LINCS node (i.e., internal PUs), a DLUR Host Circuit should be defined for each such
PU. DLUR host circuits are defined by setting both the Line Options and Link Profile
panels to DLUR. Refer to the section titled “3270 Host Connectivity” for more information
on defining Host Circuits.
• If APPN will be used to route data to dependent LUs associated with one or more PUs
which are downstream from the LINCS node (i.e., external PUs), a DLUR Gateway Circuit
should be defined for each such PU. DLUR gateway circuits are defined by setting both the
Line Options and Link Profile panels for the Upstream connection to DLUR. Refer to the
section titled “Gateway Circuits” for more information on defining Gateway Circuits.
Management - Central Control Mode contains the following utilities pertaining to DLUR
circuits:
• The Display/Update Circuit Status utility on the APPN Menu in Central Control Mode
includes information on your DLUR circuits, in addition to all other APPN dynamic and
predefined circuits.
• The Display/Update Gateway Circuits Status utility on the Communications Menu shows
the current status of your DLUR gateway circuits.
• The Display/Update 3270 LU Connections utility on the Device Menu shows the LUs
that are active on your DLUR host circuits.
APPN Configuration and Management
Configuration - The following list defines the Configuration utilities used to define APPN
Circuits. The “APPN Menu” in Configuration can also help guide you through these utilities:
• The Line Options utility defines the lines you will be using to access the APPN network,
and enables the appropriate protocols for that line.
• A Link Profile should be defined for each protocol you will be using to access the APPN
network. The profiles define link parameters, which may be shared by all of your APPN
Circuits. Among these parameters are the APPN Transmission Group characteristics.
• The SNA Options panel contains some APPN Options. Among these are the Network Id
and the APPN CP name, which are required when using APPN.
• The APPN Dynamic Connections utility defines parameters which are used to create APPN
circuits dynamically. It also allows you to define APPN lines as a part of a Connection
Network.
• The APPN Predefined Circuits utility predefines APPN circuits. This is required for some
protocols, such as SDLC and Channel/SNA.
• The APPN LEN LUs utility defines LUs residing in Adjacent LEN nodes. You must define
these LUs for LEN nodes, since a LEN’s LUs cannot be located dynamically.
