'External Exception C0000008' or 'Access Violation'
Question:
"External Exception C0000008" or "Access Violation" error with
2.3.3 SQL NET client: I get an Access Violation with Delphi 3
and an External Exception error with Delphi 2 when connecting
to an Oracle server when in Delphi's IDE or Turbo Debugger with
NT4. If I run the application alone, it executes correctly. How
do I get around the problem?
Answer:
Borland has determined that this is a problem with SQL NET
2.3.3. Oracle also recognizes this as a SQL NET problem. There
are a couple of workarounds:
- Rename or remove the registry entry
HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\OTRACE73
NOTE: This is the solution that Oracle support recommends!
- Start Oracle's Installer and remove the "Oracle Trace
collection Serveces 7.3.3.x.x"
- Turn off Integrated Debugging in Delphi's IDE
- Use an Oracle SQL NET that is older than 2.3.3
