How To Perform the Diagnose This Computer Procedure

If you have not already installed
Station Administrator, install it from your Timeslips CD-ROM using the Custom installation option and selecting only Station Administrator. If you are using Timeslips v9.0, then you must reinstall SR11.

What Diagnose This Computer Does

When the command is first
selected, it performs an analysis of your system and attempts to fix any problems it
finds. Errors are reported in the Diagnose This Computer dialog box that follows the
analysis. Here are the tests & fixes it performs during the startup:

1. Tests if BDE can be initialized
   If not, BDE is improperly installed and a warning is added to the Database Engine section of the Diagnose This Computer dialog box. When you use the Fix button, you are given instructions to reinstall BDE32. The Fix function actually deletes elements of the registry associated with BDE to allow reinstallation a better chance to work.
   
   Note that this only applies to BDE 32, not BDE 16. Diagnose doesn't support BDE 16 issues.
   
2. Validates BDE version
   For v9, it must find BDE 4.5.1 or higher. For v9.1, it must find BDE 5.0.1 or higher. BDE
   v5.1.0 is valid and reports no error although the Data Verification system will offer less
   repair capabilities with this version installed. If not valid, a warning is added to the
   Database Engine section of the Diagnose This Computer dialog box. The Fix button takes the
   same actions as in #1.
   
3. Local Share option in the BDE
   configuration file is set to ‘No’. If it cannot set it, the BDE
   configuration data is corrupted and a warning is added to the Database Engine
   Configuration File section of the Diagnose This Computer dialog box. The Fix button
   deletes your BDE Configuration file and deletes elements of the registry associated with
   BDE to allow reinstallation a better chance to work. Then it tells you to reinstall BDE32.
   
4. Max File Handles option in the
   BDE configuration file is set to 80 if it is less then 80. If it cannot set it,
   the BDE configuration data is corrupted and a warning is added to the Database Engine
   Configuration File section of the Diagnose This Computer dialog box. The Fix button takes
   the same actions as in #3.
   
5. Removes Pdoxusrs.lck,
   Pdoxusrs.net, and Paradox.lck files from your Temp folder, the current Timeslips database folder (as determined by the main window of Station Administrator), and the folder where Timeslips is originally installed. If any are found but fail to delete, they are most likely open and in use by a program that uses the Timeslips database. If any are left over, a warning is added to the Paradox Issues section of the Diagnose This Computer dialog box. The Fix button tells you to reboot and try again or delete the files manually.
   
6. Checks the version of VREDIR.VXD
   in your WINDOWS\SYSTEM directory and makes sure that it is newer then version 4.00.1114.
   If an older one is found, a warning is added to the Operating System section of the
   Diagnose This Computer dialog box. The Fix button tells you how to get an updated
   VREDIR.VXD.
   
   Note: Learn more about this problem on the Microsoft web site:http://www.microsoft.com/
   
7. If the OS is Windows 95 or 98,
   it changes the registry key System\CurrentControlSet\Services\VxD\VREDIR DiscardCacheOnOpen to a value of 1. This is associated with getting VREDIR.VXD to
   work.
   
8. In v9.1, sets BDE configuration
   options to better utilize RAM available. This is done to improve performance.
   

The Diagnose This Computer dialog box
also contains the Change Operating System Settings button. Click this if
data corruption is happening in

Once selected, a dialog box appears
with operating system specific instructions and a checkbox. When the checkbox is marked,
the operating system has been setup with a caching feature enabled. Unmark to turn off
system caching. However, if this change doesn't result in stopping data corruption, return
here to turn system caching back on.

Once you close the Diagnose This
Computer dialog box, you may be prompted to reboot your computer if any registry settings
where changed by #7 or the Change OS Settings button.

Steps to perform the Diagnose This Computer procedure:

• Close Timeslips and any other program
  that uses the Borland Database Engine (BDE).

Note: If you are unsure what programs may use BDE, close all other
programs.

• Open Station Administrator on the
  computer you wish to diagnose.

Note: If you have not installed Station Administrator, install it from
your Timeslips CD-ROM using the Custom installation option and selecting only Station
Administrator.

Note: If Timeslips is operating in a network environment, and Station
Administrator is not installed on the workstation, then use Windows Explorer to locate and
run Statadmn.exe from the Timeslips installation folder on the server.
[From the Windows Toolbar select Start; Run; Browse
to locate and open Statadmn.exe from the Timeslips installation folder on
the server.]

• In Station Administrator select Options;
  Diagnose This Computer. Click OK
  to confirm that all programs using Borland Database Engine are closed. Station
  Administrator will attempt to analyze your system.

   
• When Analyze System completes, the Diagnose This Computer dialog box will open and alert you to problems with your Timeslips database and operating system. Each of the four areas has an associated Fix button. If any Fix button is enabled, click it to either solve the problem or receive instructions for doing so. Click Help for further information.

Note: Even if no problems are reported, Station Administrator may make other necessary changes (see above).

• If you have experiencing data corruption errors click Change Operating System Settings to open the Windows 95 and 98 Settings dialog box and unmark Enable file system caching. Click OK
  to return to the Diagnose This Computer dialog box.

   
• Click Done. If prompted to do so, restart your computer.
