Thread: How remove stale DSN ?

Hi,

I upgraded to PG 8.1 and therfore uninstalled PG 8.0.4 and every older
psqlODBC version from my win2000 "development"  box.

I had several DSNs for playing around that were mostly just there
collecting dust.
Now I find that I can't open their configuration dialog nor can I delete
them because the associated driver isn't there anymore.

Is there a way to force the removal out of Windows 2000's DSN manager ?

Have your tried deleting the .dsn files directly (typically in "C:\Program
Files\Common Files\ODBC\Data Sources")?

No because I didn't know of them.
Now I checked but this directory is empty. There aren't any *.dsn files
on C: at all.
Probaply this stuff is stored somewhere in the registry.   =8-{

I had the same problem and found a quick and dirty workaround that seems to
work...
I just created a new DSN linked to the new driver and named it exactly as
the old one. I expected some sort of "Invalid name, try another" warning,
but the old DSN was simply overwritten by the new one.
I don't recommend this kind of tricks, but when one is really desperate...

It is. Check under HKEY_LOCAL_MACHINE\Software\ODBC\ODBC.ini. There's a
key for each DSN which contains the config values. Just delete the key.
Also, there will be a single value corresponding to each DSN under the
'ODBC Data Sources' key. Delete that as well. User DSNs are in the same
place, but under HKEY_CURRENT_USER.

Hack your registry at your own risk. Backup first. Etc. etc.

Let me clarify that - delete the single value, not the entire ODBC Data
Sources key.

Regards Dave

Regedit
\HKEY_LOCAL_MACHINE\SOFTWARE\ODBC
ODBC.INI contains data source names/DSNs - corresponding to the ODBC Administrator SYSTEM DSN tab
ODBCINST.INI contains driver versions registrations

\HKEY_CURRENT_USER\SOFTWARE\ODBC --or-- \HKEY_USER\%user_id_key%\SOFTWARE\ODBC
ODBC.INI contains data source names/DSNs  - USER

At the momemnt I cannot remember if other registry keys are involved so this information definitely comes
with no implied warranties.

Yes, go to registry

in HKLM there are 2 keys ODBC and ODBC.INI,
just check there.
