UNABLE TO RETRIEVE THE CLIENT IP ADDRESS AND HOST NAME OF A PORTAL USER

I'm trying to retrive the client IP address and host name of a portal user
trying to access a portal page using APIs:
PortletRenderRequest portletRequest =
(PortletRenderRequest)request.getAttribute(HttpCommonConstants.PORTLET_RENDER_REQUEST);
HttpServletRequest servletRequest =
(HttpServletRequest)portletRequest.getAttribute(HttpCommonConstants.SERVLET_REQUEST);
String l_szClientIPAddress = servletRequest.getRemoteAddr();
String l_szClientHost = servletRequest.getRemoteHost();
but i found that for all portal users on different machines IP addresses, the
returned IP is the same for all which is Portal middle tier IP address.
So how can retrive the IP addess of a portal user trying to access a portal
page ?

Brijesh,
Do you mean how to see hostname/ip address of client requests processed by the server? If yes, depending on what's your front ending component - Web Cache or OHS, you can configure the access log format to have this information recorded in either of these component's access log file.
For Web Cache access log file, refer this:
http://download.oracle.com/docs/cd/B14099_19/caching.1012/b14046/diagnostics.htm#sthref2090
For OHS access log file, refer this:
http://download.oracle.com/docs/cd/B14099_19/web.1012/b14007/servlog.htm#sthref439
By default, both Web Cache and OHS are configured to use Common Log Format (CLF) that does record hostname/ip address so if you haven't made any changes to log format, this info is already there for you. Look for $ORACLE_HOME/webcache/logs/access_log file for Web Cache and $ORACLE_HOME/Apache/Apache/logs/access_log file for OHS.
Thanks

How to retrieve the client IP address when Apache acts as a proxy for Tomca

Hello,
I am trying to retrieve the client IP address accessing the web
services. Because Apache is our proxy for all requests, when I try to
retrieve the client IP I always get the localhost IP: 127.0.0.1
The following code returns the localhost IP:
MessageContext msgContext = MessageContext.getCurrentContext();
if(msgContext != null) {
return msgContext.getProperty(Constants.MC_REMOTE_ADDR).toString();
return "Unknown";
From a servlet, obtaining the client IP address can be achieved using
this code.
String ipAddress = request.getHeader("x-forwarded-for");
if (ipAddress == null) {
ipAddress = request.getHeader("X_FORWARDED_FOR");
if (ipAddress == null){
ipAddress = request.getRemoteAddr();
return IPaddress ;
Any help is greatly appreciated.
Thank you very much

Migrate Active Directory 2008 to 2012 but need to keep the same ip address and server name

Hi,
Current setup is 2 DCs in one site running 2008 R2 AD.
We are planning to migrate from 2008 R2 to 2012 R2 but need to keep the same ip address and server name. I have came up two plans to do this and hope someone can tell me which one would be the best approach. What is the pros
and cons in Plan A and B or may be plan C if there is a better one?
First, I was planning to do plan A but just had a second thought of Plan B. My concern in Plan A is about changing the server name when the new 2012 R2 already running as DC. Plan B would be changing all the old server
name and ip before they become member sever and DC.
Any information and suggestion would be very appreciated.
Plan A
Run adprep /forestprep on 2008 R2 DC
Build a new 2012 R2 server and promote it as 3rd DCs in current Domain
Transfer FSMO from 2008 R2 to 2012 R2
Run Repadmin /syncall to force replication
Rename the demoted 2008 R2 DC to something else
Change the demoted 2008 R2 ip address to something else
Restart the demoted 2008 R2 server to take effect
Now, run Netdom computername command to change the new 2012 R2 server name to the old 2008 R2 DC server name
Change the new 2012 R2 DC's ip to old 2008 R2 DC's ip
Run ipconfig /flushdns
Run ipconfig /registerdns
DCDIAG to see any error
Plan B
Build 2 new 2012 R2 standalone servers
In 2008 R2 ServerA transfer FSMO to 2008 R2 ServerB
Demote 2008 R2 ServerA to become member server
Rename 2008 R2 ServerA to something else and change the ip address to something else and shut it down
Now, rename one of the new 2012 R2 standalone server to the old demoted 2008 R2 ServerA name
Change the new 2012 R2 standalone server ip to the old demoted 2008 R2 ServerA's ip address
Add the new 2012 R2 standalone server (now with the old 2008 R2 ServerA name and ip) to become member server
Run adprep /forestprep on the 2008 R2 ServerB
Promote the new 2012 R2 (now with the old 2008 R2 ServerA name and ip) as DC
Transfer 2008 R2 ServerB FSMO to the new 2012 R2 DC (now with the old 2008 R2 ServerA name and ip)
Demote 2008 R2 ServerB as member server
Rename 2008 R2 ServerB to something else and change the ip address to something else and shut it down
Now, rename the 2nd new 2012 R2 standalone server to the old demoted 2008 R2 ServerB name
Change the new 2012 R2 standalone server ip to the old demoted 2008 R2 SeverB 's ip address
Add the 2nd new 2012 R2 standalone server to become member server
Promote it as DC
Run DCDIAG to check error
Thanks.

Hi,
Renaming a Domain Controller is a risky operation which may lead to issues, therefore, I would suggest you go with the Plan B, rename the server before it becomes DC.
Here is a blog below which could be helpful to you:

Need to change IP address and host name on a ORACLE 10g RAC setup.

Hi Forum,
I have a task to change the IP address, host name and host related details for the ORACLE 10g RAC 2 node setup. So Can anyone tell me the procedure to do the same on both the nodes.
Regards
Prakash

change IP Address Public + VIP + Interconnect
http://surachartopun.com/2007/01/i-want-to-change-ip-address-on-oracle.html
change VIP name
http://surachartopun.com/2009/01/change-vip-hostname-on-oracle-rac.html
If you'd like to change HOSTNAME... Metalink (NOTE:220970.1)
Can I change the public hostname in my Oracle Database 10g Cluster using Oracle Clusterware?
Hostname changes are not supported in Oracle Clusterware (CRS), unless you want to perform a deletenode followed by a new addnode operation.
The hostname is used to store among other things the flag files and Oracle Clusterware stack will not start if hostname is changed.
Changing the Private Interconnect
o Change of the IP Address: change the IP address in the hosts file and/or DNS and make sure that ASM and the database also use the same interconnect
o Change of the private node name used by Oracle Clusterware: requires a reinstall of Oracle Clusterware
So, Public or Private hostnames can only be changed by removing/adding nodes, or reinstalling Oracle Clusterware. VIP Hostnames can be changed
But you can read this idea (reinstall CRS)

Register IP address and host name of SAP Router

Does anyone think there would be a problem if we register one IP address now and then register another one later, replacing the first?
Thanks.

I think that It isn't problem

Get the client IP address

Hello everybody, I'm a student new with java, I'm developing a little server application - running standalone, and I'm trying to get the client Ip address, have a look on my code snippet:
InetAddress fromcli;
while(true){
welcomeSKT.accept()
fromcli = welcomeSKT.getInetAddress();
System.out.println("The client Ip Address is: " + fromcli.getHostAddress() + '\n');
The sysout println returns the 0.0.0.0 that is the server address, mapped to more than one interface eg:(loopback and eth0) - But if with the getInetAddress() method I get the server address where is the difference with the getLocalHost()? - By the way, anyone has a suggestion to print out the client remote address.
Thank you in advance....

Oh, sorry of course welcomeSKT is a ServerSocket, actually the snippet that I put is a part of the code, here below I put the complete program, in order to clarify my question, however I would like to know if it's possible to understand from the server side the client IP address, and if yes how...
Thank you in advance...

ISSUE FINALLY RESOLVED!!!!!!
So, it turns out, I had to restore the iPhone...with a twist! Here are the steps:
FIRST BACK UP YOUR DEVICE
1. Go to the library (Hold option, click on "go" in the finder, then go to library)
2. Go to your iTunes folder in this Library (not application support, the main iTunes folder)
3. Go to the iX software folder (i.e., iPhone software, iPad software, etc.) and delete the file in this folder
4. Hook up the phone and then click on restore iPhone.
At this point, it will redownload the entire OS again. You must then restore the iPhone. As it is downloading the iOS, you can disconnect and use your phone for probably however long you want (I did the restore the same day as the download) and when you are ready you can hook up the phone and restore it.
THE MOST IMPORTANT STEP FOLLOWS:
And one many may dislike. Upon restoring the phone, you MUST select "Set-Up as new iPhone"
You need to make sure you've backed up EVERYTHING elsewhere. 3rd party, non-apple/icloud apps will lose data through this method, and you'll lose all texts, your call history, and super old voicemails. The upside is that, if you've backed up, then you can just restart the process if you forgot something. But seeing as how the popup was interfering with my ability to use iCloud (I couldn't sync anything, such as calendar events, reminders, etc., unless I had gone into mail to sign in to iCloud), it was totally worth it....no more popups.
My only wish is that this thread becomes popular. Many people have this issue and you should only use this method as a super last resort (after trying literally everything I had written previously).

I am automating the process of sending appointment reminders to my clients. I started with an alert with an email in calendar using the clients email address as a custom entry in my me card in my contacts. this was resulting in three emails being sent with slightly different versions of the same address (see my previous post). Heating someone else's suggestion I created a workflow file to send an email and calling that file from an alert on my calendar. This is working and sends only one email to the client.
My calendar is on I cloud and I access it from three different computers so I can keep my appointment calendar current. The files that send the email only exist on one computer. My other computers show error messages when those emails get sent. It seems that each computer wants to send the email. It's a small problem but is there a way that I could not get those alerts.
But appreciate any thoughts about this. It seems like both problems might be related to the iCloud system.
Thank you in advance,
Michael

Good work, catch so far Michael, does seem to be a "feature" of iCloud syncing, not sure what you could do to disable it.

CR for Enterprise 4.0: Unable to retrieve the datasource configuration

Hello Experts, I have the following issue with CR for Enterprise: I can successfully connect to our BI server, but when I select a universe I would like to build a report on, I receive the following error message about the validity of my data source: "Unable to retrieve the datasource configuration: com.crystaldecisions.thirdparty.org.omg.CORBA.UNKNOWN minor code: 0x0 completed: No". The universe I am trying to connect to is based on a relational connection and was built using the IDT 4.0 SP 1.
Thanks a lot for any guidance on how this could be resolved.
Sergey

Hi Surgey,
Well that is very strange! Is Crystal Reports for Enterprise installed on the server machine or on the local workstation?
If we are using Crystal Reports for Enterprise which is installed on a sperate workstation, try installing it on the server machine and then try to connect to universe.

I would say that it depends on the client OS (Windows 7 or Windows 8) if offline domain join could be used or not, not that much regarding the level of the domain, you can always use the
/downlevel switch to target a DC running Windows Server 2003 for example.
