Installation Notes

Removing Host Access Server (HAS) 2.x Viewers from Cache

If you are upgrading from a previous version of HAS 2.x, you must make sure that your users clear out all cached Viewer files from their browser before downloading Terminal Viewers 3.0 and 3.1 presentations. The procedure for removing cached files varies, depending on which browser is being used:

To remove cached Viewers using Microsoft Internet Explorer
  1. From the Tools menu, click Internet Options.

  2. In the Temporary Internet Files group box, click Settings.

  3. On the Settings dialog box, click View Objects.

  4. On the Downloaded Program Files application window, right-click the item that you want to remove, and then click Remove.

  5. To close the Downloaded Program Files application window, click Close from the File menu.

  6. On the Settings dialog box, click OK.

  7. On the Internet Options dialog box, click OK.

  8. Close the browser (from the File menu, click Close).

    The next time you open the browser and access a presentation, the latest Viewers will be downloaded.

To remove cached Viewers using Netscape Communicator
  1. From the Edit menu, click Preferences.

  2. In the Category tree, double-click Advanced.

  3. Click SmartUpdate.

  4. In the list box, click the item that you want to remove, and then click Uninstall.

  5. Click OK.

    The next time you open the browser and access a presentation, the latest Viewers will be downloaded.

Minimizing Disk Space Usage on Windows

If you are installing Terminal Viewers under Windows 2000 or Windows NT 4.0, it is recommended that you use either the FAT32 or NTFS file system to minimize the amount of disk space consumed. FAT32 and NTFS support smaller cluster sizes than FAT16, which results in more efficient space allocation.

Known Issues

X Windows Required to Configure Java Terminal Viewers in UNIX Environments

To configure Java Terminal Viewers, Management & Control Services (MCS) uses Java technology which requires certain graphical interface resources to be accessible. Make sure X Windows is installed and running before configuring Java Terminal Viewers in a UNIX environment.

Problems with WebLogic 5.1 and Saving

If you're using WebLogic 5.1 and save display settings, your changes might not be saved, and an exception might occur. This problem occurs intermittently, most frequently with UTS Terminal Viewer.

To avoid this problem, make sure the file includes the following:

Unsupported Characters in Configuration Names

Do not use any of the following characters when naming configurations you create with Terminal Viewers: ampersand (&), colon (:), semicolon (;), less than symbol (<), and double quotation mark (").

Enabling Licensing and Metering for Java Viewers

In order to use the Licensing and Metering functions of Management and Control Services (MCS) with the Java Viewers, you must first install the Terminal Viewers license certificate. This certificate allows up to 100,000 concurrent users to connect using the following Terminal Viewers client types: 3270 Terminal, 3270 HotGUI, 3270 Printer, 5250 Terminal, 5250 File Transfer, 5250 HotGUI, 5250 Printer, and VT Terminal.

To install the Terminal Viewers license certificate:
  1. Access the MCS console.

  2. In the MCS sidebar pane, click Functions.

    The standard MCS function icons appear.

  3. Click Licensing.

    The Licensing navigation tree appears in the MCS content pane.

  4. In the Licensing navigation tree, click Configure Licensing.

    The Configure Licensing property pages appear in the MCS detail pane.

    For details on either of these property pages, click Help in the upper-right corner of the page.

  5. Click Certificates, and then click Add.

  6. On the Open dialog box, locate the Terminal Viewers license certificate (ViewerLicense.xml), and then click Open. By default, the license certificate is located in the following directory on the myEXTRA! Presentation Services CD:


  7. When prompted, enter a description for the certificate and click OK, and then click OK to close the Certificate Install message box.

    The Terminal Viewers certificate is added to the certificate list. In addition, a Metering node and Terminal Viewers sub-node are added to the MCS Licensing navigation tree; these nodes allow you to access Metering information for Terminal Viewer clients.
