You can use the command TNSPING to check if the DB itself
is up or not . You will get the details in TNSNAMES.ORA
file .

also , another common issue could be the box itself is down
where the db resides.

ping <box-name>

also , if the DB box is in another network , can check the
tracert command(for solaris/linux os)

whether the box is getting pinged from your network .

Hope this solves your query.
