Correcting a failed hub server connection

Edit online

Use Hub Connectivity Administration to assist you in locating all of the available Tivoli Enterprise Monitoring Server data sources. Hub Connectivity Administration helps you to correct any failed connection situations that prevent you from accessing the OMEGAMON enhanced 3270 user interface and your subsequent product workspaces.

About this task

When you log on to the user interface, if the hub monitoring server connection attempt fails, the Hub Connectivity Administration workspace is displayed and notifies you that a failure occurred and the possible reason for the connection failure. The workspace helps you to correct the connection failure and to save a corrected profile to prevent future failures.

Tip: If this is your first time logging on to the user interface and a hub monitoring server is not specified in your profile, you see the Hub Connectivity Administration workspace but with a different message that states the reason for the failure. If the message indicates that your current profile does not have a hub specified, see Logon administration and customization.

Procedure

  1. On the Hub Connectivity Administration workspace that shows the connectivity failure, select the NEXT icon by moving your cursor to the icon and pressing Enter or moving your mouse to the icon and selecting it.
    The All Known Hubs (KOBHUBS) workspace is displayed showing all of the available hubs that are known to the user interface.

  2. On the All Known Hubs (KOBHUBS) workspace, place your cursor next to a hub monitoring server name and press Enter.
    The Action Confirmation panel is displayed. The panel lists information about the hub monitoring server to be used for your workspace queries. On the Action Confirmation panel, you can enter Y to confirm the action or N to cancel the action.
  3. Enter Y to confirm the action. The Hub Verification Complete (KOBHUB04) workspace is displayed and shows two green information boxes that indicate a successful TCP/IP connection.
