HOST004

Alarm level

Major.

Description

The application cannot access the host to get data for the call. One of these problems exists:

• The keyboard is locked.
• The session is owned by someone else.
• The configuration of the host on the IR system is incorrect, or the configuration of the IR system on the host is incorrect.
• The host connection is down, or the host itself is down.

Repair procedure

To resolve the problem:

1. If the keyboard is locked or you cannot access the host, take these actions:
   1. Free a session of the card by entering hfree session_number.

      The system displays a message saying whether the hfree command succeeded or failed.

   2. Enter sb_te session_numbers.

      You are asked to press Enter to display the screen currently in use by the sessions.

   3. Press the key configured as the 3270 reset key to unlock the keyboard.

      It is likely that the application assigned to that session at one point sent a screen at an inappropriate time, causing the host to lock the keyboard.

2. If you still cannot access the host, take the following actions:
   • Check that configuration settings in both systems are correct and make any required changes.
   • Check with your LAN administrator to ensure that the connection between the host and the IR system is operating, and that the host is not down.
3. If the session is owned by someone else, enter ps ef.

   The system checks if another program, like the terminal emulator or file transfer program, is using the session.

4. If another program or programs are using the session, terminate those programs and reassign the application to the session by entering hassign session_number.
5. Make sure that the session has been configured for a host LU.
