Allows you to dynamically allocate cross-domain resource (CDRSC) definitions for resources being treated as independent LUs by this VTAM®. (The cross-domain resources might actually represent application programs, dependent LUs or independent LUs in some other node's domain.)

You can override this value at the connection level by coding DYNLU on specific adjacent link stations (PU definition statements). The adjacent link station determines the boundary function link that the resource uses to access the network.

Likewise, for an adjacent control point major node, you can override the value of the DYNLU start option by specifying a different value on the DYNLU operand on the ADJCP definition statement.

DYNLU=NO

Specifies that VTAM will not use dynamically allocated CDRSC representations for sessions over adjacent link stations.

If you code DYNLU=NO, you are required to define all resources that can be accessed over adjacent link stations. If you do not define a given resource, sessions to or from that resource will fail.

DYNLU=YES

Specifies that VTAM can use dynamically allocated CDRSC representations for sessions over adjacent link stations.

If you code DYNLU=YES, you are not required to predefine all resources that can be accessed over adjacent link stations.

For subarea nodes and APPN-only nodes (HOSTSA is not specified), DYNLU=YES is meaningful only when CDRDYN=YES is coded, as the start option (either specified as YES or by the default) or as the operand.

Result: The DYNLU value is associated with an adjacent APPN node when the first link to that adjacent node is activated. When the DYNLU value is associated with the adjacent node, that value is propagated to all other links to that adjacent node as they are activated, regardless of the DYNLU value specified for each link. See Table 1 for more information about determining the source of the DYNLU value assigned to an adjacent CP and attached resources.
