Troubleshooting Installation

Determine the cause of problems and apply the recommended solution.

Windows problems

Installer fails to start If the installer does not start, perform a silent mode installation using a template file. See Installing in Unattended (Silent) Mode.
Sybase Control Center fails to start after installation Execute uafstartup.bat—see Starting and Stopping Sybase Control Center in Windows.
Cannot connect to Sybase Control Center or install Adobe Flash Player

Browsers with strong security settings, including Internet Explorer (IE) Enhanced Security Configuration, fail to connect to Sybase Control Center if they are unable to load Flash Player. When you try to connect, you might see a message similar to this: 

This content requires the Adobe Flash Player. Get Flash.

In some cases, there is no indication of the need for Flash Player; you might see only a gray box in the browser window.

To install Flash Player so that you can use Sybase Control Center, relax the security settings on your browser, including ActiveX controls in IE.
  1. To download Flash Player, click the Get Flash link or go to http://get.adobe.com/flashplayer/.
  2. Review the license agreement and click Agree and install now. If your browser’s security options are too strict, they prevent Flash Player from installing.
  3. Change the level of security so you can install Flash Player:
    • In Internet Explorer, go to Tools > Internet Options > Security tab > Internet > Custom level .

      Most options in the Security Settings dialog have Disable and Enable settings. Many also have a Prompt setting, which means that IE prompts you for approval before using the feature or performing the action described. Set all disabled options in the dialog to Enable or Prompt. Prompt is safer.

    • In Firefox, go to Tools > Options > Content and Tools > Options > Security and choose less restrictive settings.
  4. Return to the main window and reload the Flash Player installation page. Flash Player installs automatically and plays a small animation when it finishes.
  5. Connect to Sybase Control Center and log in.
Running scripts is not enabled If you see Running scripts is not enabled or a similar message while you are connected to Sybase Control Center, relax the security settings on your browser as described in the previous item.

UNIX problems

UNIX operating systems include Linux, Solaris, and HPUX.

$DISPLAY environment variable is not set correctly This error message means that the $DISPLAY environment variable on the remote machine is not set correctly to display the installer to your local machine.

To correct the problem, enter the following command at the UNIX prompt of the remote machine, where host_name is the name of the machine on which you want the installer to appear (that is, on your local machine):

For C shell: 

setenv DISPLAY host_name:0.0

For Bourne shell:

DISPLAY=host_name:0.0; export DISPLAY
Client not authorized to connect to server If you see this error message when you launch the installer, the remote machine does not have permission to display the user interface on the local machine where you are working: 
Xlib: connection to "host_name" refused by server
Xlib: Client is not authorized to connect to Server
xhost: unable to open display "host_name"
To correct the problem:
  1. Enter the following command at the UNIX prompt of your local machine, where remote_machine is the machine on which you are running the installer:
    xhost +remote_machine
  2. Restart the installer.
Installer fails to start If the installer does not start (which happens, for example, when no X Window system is available), add this option to the installer command: 
-is:javaconsole
For example,
./setup -is:javaconsole

This option runs the installer and displays any error messages on the console so you can correct them.

You can also run the installer in silent mode; see Installing in Unattended (Silent) Mode.
Sybase Control Center fails to start after installation Execute uafstartup.sh—see Starting and Stopping Sybase Control Center in UNIX.
