Any idea how to resolve a BDE error $251e?

Question

Here's the situation:

A user of our program suddenly started receiving an error from the Borland Database Engine (BDE) when attempting to start the application. The error message says that it was unable to initialize the BDE and gives error code $251e. User is on BDE 5.2.0.2.

I cannot find any official documentation on the error $251e. The only somewhat useful hit I can get on Google is not very instructive and the suggestion there does no good.

Here are some things that we have tried / discovered:

1. Other applications that access the BDE the exact same way have no complaints.
2. The error occurs on a line where we set Connected := True on the TDatabase component.
3. Reinstalling the BDE makes no difference.
4. Closing all BDE apps except the one in question makes no difference.
5. Changing from using an MSSQL database to a Paradox database makes no difference.
6. Making the logged in user a member of the Administrators group on the workstation makes no difference.
7. The typically logged in user is a domain user.
8. Logging in as a workstation administrator (non-domain) account that was originally setup on the machine as a last resort administration account, all works fine.
9. Creating a new workstation user with local admin rights, the problem returns.

The user has been temporarily allowed to use the one workstation admin account that actually works, but this is not an acceptable long-term solution. Any idea where we might go from here? Any clue as to what $251e really means?

I know that the BDE is way out of date and no longer supported, but changing the use of the BDE is not an option right now.

You might have better luck searching for the error here..

A common culprit seems to be a conflicting device driver.

Good luck

Answer 2

I am not sure, because I don't use BDE for lot's of years, but here are some hints and links:

• Error is probably related to BDE parameters (as article you linked claims)
• Here are some sites that have some suggestions for optimal BDE configuration
  • http://www.kennedysoftware.ie/oldapps.htm - check BDE section, have information about BDE configuration and some advices about using BDE with Vista
  • http://www.thedbcommunity.com/index.php - community site about Paradox and BDE
  • BDE issues from Codegear quality central
  • search newsgroup borland.public.bde - there is lots of questions about #251E

Error $251E means "Insufficient shared memory available"

Proposed solutions:

• Increase SharedMemSize to 4096 or 8192
• Change SharedMemLocation to 0x5BDE.
