Defining DLUR PUs

Normally, a dependent LU session requires a direct communications link to the host computer. If many nodes (including a host node) are connected together in an APPN network, some of them may not have a direct connection to the host, but only an indirect connection through another node. It is not possible to establish dependent LU sessions to the host from LUs in these indirectly connected nodes.

Dependent LU requester (DLUR) is an APPN feature designed to overcome this limitation.

This section explains how to configure a DLUR PU that provides connectivity to a host computer. Configuring a DLUR PU enables the local node to provide DLUR services.

DLUR on an APPN node (such as a node running SNAplus2) works in conjunction with dependent LU server (DLUS) at the host, to route sessions from dependent LUs on the DLUR node across the APPN network to the DLUS host. The route to the host can span multiple nodes and can take advantage of APPN's network management, dynamic resource location, and route calculation facilities. DLUR must be available on the node where the LUs are located, and DLUS must be available on the host node, but DLUR is not required on any intermediate nodes in the session route.

To configure a DLUR PU, use one of the following methods:

Motif administration program

Select Connectivity and New DLUR PU from the Services menu on the Node window.

Command-line administration program Issue the following command:

define_internal_pu

DLUR PU Configuration Parameters

The following parameters are required for DLUR PU configuration:
