Hi all:

I installed 8.17 and 9.02 on the same box under different O-H. However, when I tried to connect to the 9i DB using 8i SQL*Plus, I get the "TNS.... error". I got the same error when trying to connect to the 8i DB using 9i SQL*Plus. How do I get around this problem. Any help/advice will be much appreciated.

TIA

John
