I recently purchased a new laptop, installed oracle 10g express (because it was free) in it. But when I tried to connect using client utilities, I was getting this annoying, ORA-06413 "Connection not open" error. I found the reason! I am having a 64 bit OS and by default, all 32 bit apps are installed in the path, c:\Program Files (x86). Oracle 10g doesn't support special characters like "(", ")" in it. So I have to uninstall the software and reinstall it in a different directory.
If you have any questions regarding this, post me a comment! I will not promise that I will give you an answer immediately, but I will try to answer as quickly as possible.
See you in next post!
