TN5250 Administration
The local LU, remote LU, and mode must match the configuration information in Host Integration Server.
To enable an APPC session with the IBM i, you must provide the user ID and password for conversation security. For the correct information, Contact your IBM i administrator.
The TN5250 requires that TN5250/IBM i definition terminal names allow the TN5250 service to accept client requests from client computers that emulate those types of terminals.
To set up Host Integration Server for TN5250 access
Open SNA Manager console tree.
Install and configure a link service, if this has not been done.
Insert a connection to an IBM i that the TN5250 clients will access. Configure the connection with Remote End as Peer System.
Configure a local LU and a remote LU for access to an IBM i, making sure the mode for the remote LU is QPCSUPP.
On the File menu, click Save Configuration to put the changes into effect.
To add and configure LUs for TN5250 service
Before LUs can be added to the TN5250 service, you must first install a link service, add a connection to an IBM i on this link service, and create local and remote LUs for accessing this IBM i.
Right-click TN5250, point to New, and then click TN5250 IBM i Definition.
Configure the properties of this TN5250 IBM i definition.
If you do not specify an IP address for an LU, the default value will allow any TN5250 client computer access to this LU.
Click Help for information on the property options.
Click OK to close the IBM i Definition Properties dialog box.
On the Action menu, click Save Configuration to put the changes into effect.
Configuration changes are apparent only to users who establish a connection after the configuration changes are saved. Users who were connected at the time that the configuration changes were made will not be affected.
You can modify, delete, or add IP addresses and subnet masks to IBM i definitions. If you want to change the configuration of multiple IBM i definitions, you can only change properties such as display types, the IP address, and subnet mask that the IBM i definitions have in common. You cannot change properties such as the local or remote LUs, because these values are unique for each IBM i definition.
You can add new IP addresses and subnet masks to a range of IBM i definitions. If the new IP address or subnet mask already exists on some of the IBM i definitions, but not on others, the addition will occur without duplication in the ones that already have the IP address or subnet mask. You can also modify or delete the IP addresses that the IBM i definitions have in common and that appear on the IP address list.
To edit an IBM i definition for TN5250 service
- In the SNA Manager console tree, select the TN5250 service IBM i definition that you want to view or modify, right-click, and then click Properties.
To delete IBM i definitions from TN5250 service
In the SNA Manager console tree, select the icon for the IBM i definition that you want to delete.
Click Delete.
Click Save to save your configuration changes.
Note
Configuration changes are apparent only to users who establish a connection after the configuration changes are saved. Users who were connected at the time that the configuration changes were made will not be affected.
To start, pause, continue, and stop TN5250 service
Right-click TN5250, and then click Start or Stop.

In the Services utility of the Windows Administrative Tools, select TN5250 Service and click Start, Pause, Continue, or Stop.
The TN5250 service is set to start manually by default. You can change this to automatic if you are not running either the TN5250 service on this server, or if you have configured the TCP ports for more than one of these services.
After TN5250 service has stopped, it can no longer be accessed. You may need to start the TN5250 service after you have paused or stopped it. TN5250 service can be restarted only on the local system.
Pausing allows you to prevent new users from establishing a connection with TN5250 service without disconnecting current users. You can then view session status in the Active TN5250 Sessions folder and notify connected users to disconnect from TN5250 service.
Before stopping TN5250 service, notify all connected users that they will be disconnected within a specified time period. Stop the service after expiration of your warning period.
