Hi all,

I have W2K03 Server with Oracle 10g installed and Oracle Client 9i installed on the same server.
I have 2 problems : 1) When I open "Start-->Run-->Cmd-->Sqlplus" it point to sqlplus of the 9i

2) I can connect from SQLPLUS of 10g, but cannot connect from SQLPLUS of 9i because I have these errors :

error a) ORA-12203 if I use "SQLPLUS system/pwd"
error b) ORA-12222 if I use "SQLPLUS system/pwd@O10G"


Someone can Help me ??

Thanks.


Hereby the listener.ora and tnsnames.ora of 10g and 9i
