Configuring Dependent LUs
Defining LU Pools
Defining LU Pools
For 3270, TN3270, RJE,and LUA, you can define LU pools to simplify
user configuration and provide greater flexibility in establishing host
sessions. For example, you can define several 3270 LUs in a single LU
pool, then configure multiple 3270 sessions using this LU pool. This
makes configuring the 3270 sessions easier and enables any 3270 session
to use any LU in the pool.
LU pools can even span multiple SNAplus2 servers—just define LU
pools with identical names on the different servers. If a server fails or is
taken out of service, clients that use the LU pool can then use a different
server. Using LU pools also simplifies client configuration and makes it
easy to increase capacity by adding another server or by adding LUs on
an existing server.
You can view all of the LU pools for the SNAplus2 domain using the LU
Pools window. This window lists the LU pools configured in the system,
and enables you to select LUs to add to an LU pool. The individual LUs
in an LU pool are listed below the LU pool.
An LU is identified as follows:
• 3270 display LU
• Unrestricted LU
• SCS Printer
• 3270 Printer
Do not mix LUs of different types in the same pool (for example, do not
put display and printer LUs into the same pool). It is unlikely that you
will need a pool of printer LUs unless you are supporting TN3270E
clients.
To configure an LU pool, use one of the following methods:
Motif administration program
Select LU Pools from the Windows menu on the Node
window, then choose New to add a pool.
Command-line administration program
Issue the following command:
define_lu_pool
