To set up host access IDs so that you can use a single EXTRA! X-treme session configuration file for multiple clients to establish multiple sessions with a host. Applies to TN3270 and TN5250 connections.
Use MCS to create pools of host access IDs and then assign them to session configurations. When a session is started, it gets its ID from Management & Control Services (MCS) and uses the ID to connect to the host. For TN3270 sessions, IDs are dedicated LU (resource) names configured on a gateway, such as Attachmate SNA Gateway; for TN5250 sessions, the IDs are device names.
MCS keeps track of the IDs that are in use. If all the IDs assigned to a pool are in use, no other host sessions can be opened through that pool.
To use ID management with EXTRA! X-treme, you use the following components:
You need to decide which of several types of ID pools to use. The type of pool you select depends on how you want to control access to the host. For more information, see Configuring ID Pools.
You must set up your directory service in MCS before you can create ID pools based on user names. In addition, for TN3270 hosts, the IDs you create in MCS must map to existing LUs.
