As previous posts have asked - supplying additional information will assist in problem determination such as:
- what version is your DB2 client?
- do you have multiple DB2 clients installed, If so what is your default?
- what is the bitness of your default DB2 client (32 or 64)?
- does Toad see your cataloged connections?
- can you catalog any additional connections in Toad?
- can you export and post your windows registry at:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\IBM\DB2
and/or
HKEY_LOCAL_MACHINE\SOFTWARE\IBM\DB2
Thanks
