Not able to access the Enterprise Manager WebClient

Postby tmack8080 » Wed Apr 03, 2013 8:20 pm

Hi,

I am setting up an Oracle Linux 6.4 + Oracle 11g R2 11.2.0.3 test server.

I am able to login to the EM WebClient on the local server but not from my Windows PC. I have a Windows server 2008 R2 box hosting the same Oracle version and am able to access the EM WebClient on that box from my PC.

I get the error:

"This page can't be displayed"

I am using the IP (http://192.168.1.xx:1158/em) - I can ping the IP and set >$emctl unsecure dbconsole

I tried IE, Chrome and Firefox.
I tried multiple PCs.
The firewall on the Linux box is turned off, test lab.

Any ideas?

BTW: I read your post about the most common problems with accessing the EM WebClient and none of your suggestions resoled this issue. Just wanted to let you know I tried that before posting this question.

Thanks,

Tim...

Hi.

If you hadn't said your firewall was switched off on the database server I would say it was a dead cert that the firewall was turned on. Can you just check once more that it is actually turned off. You can do this by issuing the following command as the root user on the database server.

Code: Select all

# service iptables status


Post the output here please.

The only other reason why I can think this might be happening is if there are some other firewall restrictions present in your network. For example, the server may be running in a trust network and you may be in an untrust or DMZ network. If this is the case it may not be the firewall on the server or your PC that is blocking the communication, but a firewall in yuor network that is doing it.

Cheers

Thanks for the reply. Here is the output:

[root@OracleLinux -J# service iptables status
Table: filter
Chain INPUT (policy ACCEPT)
num target prot opt source destination
1 ACCEPT all —— 0.0.0.0/0 0.0.0.0/0 state RELATED,ESTABLISHED
2 ACCEPT icmp —— 0.0.0.0/0 0.0.0.0/0
3 ACCEPT all — 0.0.0.0/0 0.0.0.0/0
4 ACCEPT tcp —— 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:22
5 REJECT all —— 0.0.0.0/0 0.0.0.0/0 reject—with icmp—host—prohibited

Chain OUTPUT (policy ACCEPT)
nurn target prot opt source destination
END
*********************************************************************************************
So I disabled everything, again, and now it works.

[root@OracleLinux ~]# service ipchains stop
ipchains: unrecognized service
Lroot@OracleLinux ~]# service iptables stop
iptables: Flushing firewall rules: [ 0K ]
iptables: Setting chains to policy ACCEPT: filter [ 0K ]
iptables Unloading modules: [ 0K ]
[root@OracleLinux ~]# chkconfig ipchains off
error reading information on service ipchains: No such file or directory
(root@OracleLinux ~] chkconfig iptables off

Guess I should have checked my work. Newbie mistake.

Thanks for your help.

Cheers

No problem. It happens to us all. I forgot to put an entry in the /etc/hosts file the other day and couldn't understand why my WebLogic configuration was failing. :)
