W3DBSMGR ( Error 8520

W3DBSMGR ( Error 8520

Hello Mirtheil,

Each and everytime I logon to my Windows XP PRO workstation, I encounter this error message:

W3DBSMGR ( Error 8520 - A timeout occurred during the initialization of SRDE engine.

My observation is that the Pervasive Engine icon in the System Tray also does not launch.

Please explain the problem and its solution?


RE: W3DBSMGR ( Error 8520

Not enough information to help.  
How did you install the PSQL engine?  
WHat version of PSQL is installed?  

Usually that error means there's a missing component.

Pervasive.SQL 9.5 Workgroup Engine.
Pervasive was installed by an Administrator by running the "PSQL-Workgroup-" file from a Network Folder while sitting on the Terminal Server.

This error does not appear when logging to the Terminal Server as an Administrator but appears when other users logs on.

The Terminal Server is running Windows Server 2003 Standard Edition (+sp1).


RE: W3DBSMGR ( Error 8520

Have you done anything other than install the PSQL Workgroup Engine?  
The WGE runs as a standard process and can only load once.  In a TS/Citrix environment, the WGE tries to load multiple times when multiple users run it.  
Are you trying to access the data locally on the TS?  
Also, how many users are you going to have?  It it's more than 5, you'll probably want to switch to the Server Engine.   The Server Engine also runs natively as a service so it handles TS/Citrix environments better.

I did find the following in the Pervasive documentation:


Terminal Server as Network Server

You may use your terminal server as your main network server and database server. However, if you have high usage of the server as a file server as well as many terminal sessions running at the same time, you may find the performance less than satisfactory.

Another concern is having all of your mission critical services on the same machine. If it goes down, all of your services go down at once.

For these reasons, you may wish to consider distributing your mission critical services on two or more computers.
Workgroup Engine Running as a Service

You may configure your server to run the Workgroup engine as a service. This allows the engine to start automatically when the operating system starts. A user is not required to log in to start the engine. Refer to Running the Workgroup Engine as a Service .
