Configuring SNA Resource Manager 45
Configuring SNA Resource Manager
Eicon SNA Gateway’s SNA Resource Manager controls the definition and
allocation of all SNA resources. These resources include Nodes and LUs.
Adding and Deleting SNA Resource Manager Items
The SNA Resource Manager’s Nodes and LUs are manipulated from within
the information window. After you select a component in the Navigator, click
one of the items listed in the information window before you insert, delete, or
modify them. Each time you make any changes to these resources, they must
be stopped and restarted, with the ECSNA command, for the changes to take
effect.
IBM Architecture
In IBM’s architecture, the access point into the SNA network and to a host
computer is the Logical Unit (LU). One or more LUs are always managed by
a Node (Physical Unit or PU), which is generally implemented by a dedicated
piece of equipment called the cluster controller. The gateway protocol software
can emulate multiple cluster controllers on the same Eiconcard, requiring
minimal overhead on the gateway PC. Each Eiconcard can emulate up to 32
Nodes (PUs), with up to 254 fully configurable LU definitions.
