Configuring Session Pools
Before you define pools, you should have defined the CUs, Host Circuits, and the
sessions that belong to them.
Sessions may be pre-assigned to TN3270 clients or gathered together into a pool of
sessions where they are doled out one at a time to clients requesting a session from the
pool. The CNA-8000 supports multiple pools. Four methods can typically be used to
obtain sessions from a pool.
Method 1:
When clients connect to a specific TCP port number they are
automatically mapped to a session within the corresponding pool. Using specific TCP
port numbers allows for reconfiguration of resources on the CNA-8000 without having to
reconfigure individual user platforms.
Method 2:
Each client that is to use the pool is configured with the name of the pool
which is requested at connect time. This pool name is configured in the client’s
LUNAME field. Connection in this case can be through any configured listening port that
allows the user to specify the resource. You must configure the listening port as ‘User
Defined’ to use this method.
Method 3:
A nickname is configured into the client in their LUNAME field. On the
CNA-8000 the nickname is assigned to the pooled resource through configuration. Use of
the nickname allows reconfiguration of the resources on the CNA-8000 without having to
reconfigure the individual client platforms. You must configure the listening port as
‘User Defined’ to use this method.
Method 4:
Select the pool from a menu posted on the client’s screen at connection
time. You must configure the listening port to provide a menu to the client.
