i was unable to log in to the server using putty. when i tried to ping, the server is up. when go physically to the server, was unable to get the #prompt. what could be the possibly reason for this? we need to shutdown the database before we can force shutdown the server. afraid force shutdown before shutdown the database properly. hope to hear from you

Solutionputty is telnet/ssh client.
1) identify whether telnet/ssh is enable in that server.
# netstat -a | grep -e telnet -e ssh
If its running, you shld see the process and it should be listening (LISTEN).
2) check whether the ports are open. (23-telnet and 22-ssh)
From your pc command prompt, type :
C:> telnet
or
C:> telnet
If you receive a blank, that means the port is open and you could connect to the server.
And lastly, Identify whether you choose correct mode of connection of you putty.
Assign some points if this answer your question,...
Thanks

Re: unable to log in to the server using putty
No, if you can't login, the server is by definition "down". It doesn't matter if you can ping it. Typically ping is so low level it works where the machine could still be hung.
But as Khairy said, there may be different reasons putty, rlogin, telnet, console may fail.

Re: unable to log in to the server using putty
But you could have shutdown the database when you were at the console.

Re: unable to log in to the server using putty
Is the server up ? don't know
Is sshd running ? don't know
Is the server hung ? don't know.
....
.....
Please connect to the system console and attempt to log in. This will initially prove or disprove if the server is responding at all.
You mention very little in your post ( unable to login using putty ), but leave open a lot of speculation ( need to shutdown database before we force server shutdown ).

Re: unable to log in to the server using putty
May be you can try restarting the inetd services.
