Help,

I have a developer who is receiving the following error in the test database daily and sometimes in prod.
This error is followed by a disconnect.

DataWindow Error
Select error: ORA-01041: internal error.hostdef extension doesn't exist.

I have checked my alert log and trace files to find nothing. I am thinking this error is on the client side, since I show no errors.

Has anyone else experienced this problem?

Thanks in advance
Kathy
