Hi

I have purchased LIVE IP on my application server to access it anywhere on the internet.I am calling application on the internet as

http://192.168.1.56:7778/forms/frmservlet?form=abc.fmx

And its working perfectly.

I have configured Sigle Sign On and using this code on "When-Button-Pressed" to call report
WEB.show_document('/reports/rwservlet?server='||:PARAMETER.reps
			  ||'&ssoconn=default/oracledb/userid'
                       	  ||'&report='||repid
                          ||'&desformat=PDF'
                       	  ||'&destype=CACHE'
            	          ||'&pyear='||:PARAMETER.pyear
	                  ||'&branch='||:PARAMETER.branch_id
	                  ||'&bk='||:transactions.book
	                  ||'&sno='||:transactions.srno	
	        	  ||'&paramform=no'
		        ,'_blank');

From Client side When i press button "sigle sign on authentication page" of Internet Directory is not coming. Because URL is accessing the application server using the HOSTNAME of application server instead of IP ADDRESS
like this
http://jibran:7778


How can i configure it to use only IP address.

Thanks in advance.

Thanks.

I think this is releated to Oracle Forms and Reports.

ASAIK; Can you try to set static IP in your code.

i can't hard code the IP address in URL as there are two lan cards in my application server one for accessing it from lan and other for the internet.

i mean for accessing report server from lan the URL would be

http://localip:7778/rwservlet?server=repser



and to access it from internet the URL would be as


http://staticip:7778/rwservlet?server=repser

Locally its working fine, as i am able to access application server using HOSTNAME.

It is giving error when accessed from internet, because i can only access application server using IP ADDRESS and not the HOSTNAME.

Is your host name known to your internet client DNS?

No, They can only access using IP ADDRESS.

Well, no matter what else, they won't be able to access an IP address in the private 192.168.0.0/16 IP range from "the internet" anyway.

You are not getting my point. As i said i have purchase LIVE IP to access my application sever from anywhere on internet, they are using this LIVE IP to connect and its working fine.

i have configured sigle sign on. i have set "ssomode=false" in formsweb.cfg file and have set "SIGLESIGNON=YES" in rwservlet.properties file.

when we run report OID server retrieves the "SINGLE SIGN ON AUTHENTICATION PAGE" using the HOSTNAME of application server.

so its working fine in lan because we are able to access application server in the lan using HOSTNAME.

But for internet clients they can only access application server using LIVE IP and not HOSTNAME.

so how can i configure OID to display "SINGLE SIGN ON AUTHENTICATION PAGE" using IP ADDRESS.


kindly help me.

Well, you would to go through your application code and configuration, and replace every instance of the server name with the IP address.

Another option would be:

Add the IP Address / Servername pair to the C:\WINDOWS\system32\drivers\etc\hosts (or /etc/hosts ) file on the client machines, or to get a DNS entry for the IP added somewhere, possibly in a place like www.dyndns.com.

Isn't there an option to add a DNS entry wherever you did this "I have purchase LIVE IP" thing?

Then you could have the same DNS servername pointing to the external address from the internet, and to the local address from the LAN.

It will work because the name will get resolved to the IP address you choose.

Hi

recently we have added another network card in our application server machine and bought another LIVE IP from another ISP.

Now there are three network cards in our application server machine.
One for local network (intranet).

Two other for accessing our application server on the internet.
>>For these two we have bought two LIVE IP addresses from two different ISPs. Idea is that if anything happens to one of these our clients could access our application by second LIVE IP.

I have added these two enteries on our clients machine's host file
192.XXX.XXX.A           myhost
192.XXX.XXX.B           myhost       


URL to access application sever on client machine is
http://myhost:7778/forms/frmservlet?config=default


It works fine when our client can access it by first IP(192.XXX.XXX.A) in the host file.
But when it stops working they should be able to access it with second IP (192.XXX.XXX.B) but its not happening .
And after entering login information following error displyed in applet.

java.lang.ClassNotFoundException: oracle.forms.engine.Main


Kindly help what is the solution of this problem

I think you are describing a similar problem that I have had to deal with a couple of times with Collaboration Suite: Your SSO server is in a secure area of the network, where internet users cannot get to it. The answer was to configure the Web Cache on the Application Server middle tier instance to forward requests from the internet to the SSO server.
Can you use your middle tier web cache in the same way, to forward all requests from the internet to the appropriate internal service?

Oracle internet directory / application server midle tier are on the same machine.

There are two enteries in hosts file on the client side to connect client to application server.
192.XXX.XXX.A           myhost
192.XXX.XXX.B           myhost       


our client can connect to our application through first IP (192.XXX.XXX.A) when communication for this IP is there. There is no problem.

What i want is that when communication for first IP (192.XXX.XXX.A) stops, clients should be able to connect through (192.XXX.XXX.B)

This error is occurs only when communication for first IP stops working.

Also this has been taken from oracle application server installation guide.

Quote:


4.8.2 Installing on Multihomed (Multi-IP) Computers
You can install Oracle Database on a multihomed computer. A multihomed computer is associated with multiple IP addresses. This is typically achieved by having multiple network cards on the computer. Each IP address is associated with a hostname; additionally, you can set up aliases for the hostname. By default, Oracle Universal Installer uses the ORACLE_HOSTNAME environment variable setting to find the hostname. If ORACLE_HOSTNAME is not set and you are installing on a computer that has multiple network cards, Oracle Universal Installer determines the hostname by using the first name in the hosts file (typically located in DRIVE_LETTER:\WINDOWS\system32\drivers\etc).




Kindly help

As I said before, you can use your Web Cache. Configure it to listen on both addresses, and forward requests to the address your http server is listening on.
