Hello bong,
When you say that you use this URL:
... by the way... this "hostname1" is a regular URL? Or it is something like:
==> http://computer1:1158/em
What I mean is: The format is...
a) http://dbsvr.mydomain.com:1158/em
b) http://computer1:1158/em
If you are on "computer1" and you issue URL like [b]... you will reach and get connection with the OEM server.
If you are on **other** computer and you issue URL like [b]... you will probably not get connected with the OEM server because this other computer does not know who is "computer1"... unless you are in a Microsoft NetBIOS environment or there is "computer1" definition in hosts file of this other computer.
Why this?
Because this URL should have the name resolved and in this case (URL type [b])... regular DNS server will not translate. Does not look like regular/tradicional URL... (I mean... a valid domain).
If [b] is your case... try to use IP address instead of name "computer1"... like below:
http://172.16.254.90:1158/em
Regards,
mson77

sir mson77,
i had tried using IP several times but still the same..no connection..
by the way, the server is having another network card used for MS loopback adapter. enabling and disabling this did not create any good result..
thanks...

Hello bong,
The error message below...

tells you that:
1) Your computer can not reach "hostname1"; or
2) "port" (tcp port number) at hostname1 is firewalled (filtered/blocked);
3) Check your browser setting regarding connection and proxy setting;
What you can do:
1) At your computer... try to ping:If it is ok... then the route and name resolution is fine (you can use either name ou IP address from this computer to reach "hostname1");
2) Check firewall rules at hostname1 if the tcp port (1158 in my example) is opened;
What is the minimum expected:
1) As you said that you can browse OEM from hostname1... the OEM service is running;
2) Then at other computer you should receive at least an OEM web page independent of your oracle DB connection status connected or not;
Try to write here as much as complete and reliable information to get good help.
Regards,
mson77
