Thanks Saurabh - that helped a lot but I still have another problem -

When I try to connect to the sample database I've created when installing,

ORACLE_SID is sample1 and the database files for these exist under /u02/oradata/sample1

SQLPLUS gives me an error after prompting for userid and password. Below is the actual message:

>sqlplus

SQL*Plus: Release 8.1.7.0.0 - Production on Fri Oct 5 12:46:41 2001
(c) Copyright 2000 Oracle Corporation. All rights reserved.

Enter user-name: scott
Enter password:
ERROR:
ORA-12545: Connect failed because target host or object does not exist.

Same error comes even with server manager, any advise/thoughts?

Thanx again,
Sri
