Connection Problem


When trying to connect to an 8i database using which I just installed, I am getting an error message of “Unhandled Exception at startup - ORA-24316: illegal handle type”. I would appreciate it if anyone can shed some light on this. Connection type is TNSNAMES, using TCP/IP. I would guess that it is a configuration issue, but I have no idea where to begin looking.



I had the same problem. Your Oracle Client needs to be updated. See thread “Error with beta 3”. This thread is probably pushed to the second page by now.



Thanks for the quick response. My client version is What is the minimum required client version for 6.0?


I’m not sure what the minimum is, but I went from to and it worked.



OK, I’ll upgrade to 9. something and try again.
