version problem in oracle10g

 

  

Hi all,

I have installed oracle10g database on windowsXP , and its working
fine.

But when I am typing "sqlplus /nolog" in command window it is giving
message as follows:

SQL*Plus: Release 9.0.1.4.0 - production on thu Oct 27


Also I am able to connect to databases in the same system and other
system but if I give tnsping it is giving error message:

What might be the problem.

ASAP

Thanks & Regards
J.Venugopal
