using Cloning..you can change the hostname...it's very cool method. You do it using cloning..then you can come to conclusion that, how we can play with cloning. Earlier i have used this method to change hostname instead of autoconfig.
(1) Run the preclone on the system where you want to change the hostname. If it is single node, run the preclone on both the Database tier and Application tier
(2) Change the Host Name of that system using Operating System Commands. Then add the entry in the /etc/hosts file
(3) Run the post clone in the Database tier and Application tier...While Answering the questions, give the new hostname for hostname question. Leave other as it is.
Or else
If you want to change the Hostname of Application tier and Database tier using Autoconfig
Follow these Documents
(1) How to change the hostname and/or port of the Database Tier using AutoConfig Doc ID: Note:338003.1
(2) How to change the hostname of an Applications Tier using AutoConfig Doc ID: Note:341322.1
Choose which method you want...
As per my suggesstion...use Cloning to change the hostname...it's Coooollllll

You sometime have to change hostname or domainname of your Apps Instance , today's post list various options & things you need to note while changing hostname on your existing Apps Instance.
Use cloning for changing hostname or domainname
I am sure you might be surprised to see how cloning can change hostname or domainname , yes you are right cloning will not change host or domain name but cloning can be used to change pointers to old hostname or domainname in Apps Instance after changing hostname/domainname by operating system commands. Steps you have to do is
Run adpreclone on Instance where you want to change hostname/domainname
Release Unix/Linux machine to sysadmin for changing hostname
Run postclone with new hostname/domain with same SID to change new name into effect
Above method is easy & best which I can think .
Use Autoconfig to change hostname or domainname of machine hosting apps Instance
If Machine on which you want to change hostname/domainname is on application tier then you just change entries in $CONTEXT_NAME.xml
Change hostname or domainname using operating system commands
execute autoconfig on that Instance so that application tier register new hostname/domainname
If machine on which you want to change host/domain name also host Database Tier then you also need to Deregister database tier from Net Service Topology Model & Reregister it with new hostname settings.
If you want to learn more about Net Service Topology Model follow Metalink Note # 218089.1 Autoconfig FAQ Under Section Net Services Question 28 to 41
For exact steps on how to change hostname using Autoconfig follow Metalink Note # 338003.1 How to change the hostname and/or port of the Database Tier using AutoConfig
I recently completed OCA for Application Server Exam 1Z0-311 and will be sharing my experience with Oracle Certification for Application Server with you all. Stay tuned on Oracle Application Server Certification 1Z0-311 & lot more things.
Your feedback/comment is quite important for improving this blog so feel free to leave your comments & suggestions

The Basic Steps for Cloning
After installing the Rapid Clone and AutoConfig patches, you are ready to clone an instance. There are ten basic steps involved. I have outlined them below:
1.Run system configuration on the Application tier:
<COMMON_TOP>/admin/scripts/<SID>/adautocfg.sh
Use the APPS password when prompted.
2.Run system configuration on the database tier:
<RDBMS ORACLE_HOME>/appsutil/<SID>/scripts/adautocfg.sh
Use the APPS password when prompted.
3.Copy AutoConfig to the RDBMS ORACLE_HOME:
Apply patch 2952369 to acquire adchkcfg utility.
Create appsutil.zip file by: perl <AD_TOP>/bin/admkappsutil.pl.
Copy appsutil.zip file to the <RDBMS ORACLE_HOME>
unzip -o appsutil.zip
4.Generate the database context file:
cd <RDBMS ORACLE_HOME>/appsutil/bin
adbldxml.sh tier=database appsuser=<APPSuser> appspasswd=<APPSpwd>
Output log is written to: $ORACLE_HOME/appsuti/out/<SID>/cfgcheck.txt
5.Generate and apply AutoConfig configuration file:
cd <RDBMS ORACLE_HOME>/appsutil/bin
adconfig.sh contextfile=<CONTEXT> appspass=<APPSpwd>
6.Prepare for source database clone:
cd <RDBMS ORACLE_HOME>/appsutil/scrips/<SID>
./perl adpreclone.pl dbTier
7.Prepare for source application clone:
cd <COMMON_TOP>/admin/scripts/<SID>
./perl adpreclone.pl appsTier
8.Copy the application tier file system:
Logon to the source system as APPLMGR and shut down the server processes.
Copy the following application directories from the source to the target node/file system:
<APPL_TOP>
<OA_HTML>
<OA_JAVA>
<COMMON_TOP/util>
<COMMON_TOP/clone>
<806 ORACLE_HOME>
<iAS ORACLE_HOME>
Shut down the source database and copy it to the target node/file system.
Restart the source database and source application server processes.
9.Configure the target system database sever:
cd <RDBMS ORACLE_HOME>/appsutil/clon/bin
./perl adcfgclone.pl dbTier
10.Configure the target system application tier:
cd <COMMON_TOP>/clone/bin
./perl adcfgclone.pl appsTier
Note: These steps are for a single node install. If you are using Oracle Workflow, you must update wf_notification_attributes and wf_item_attribute_values.
Version 2.1.0.17 of the Oracle Universal Installer and Perl 5.005 should be installed and included in your path. Be sure to review your install logs after cloning to make sure there are no errors. After you have verified connectivity in the cloned environment, have a user navigate through the system to verify the clone is functional and complete.

Run AutoConfig to change hostname for E-Business Suite
Oracle E-Business Suite is dependent on hostname. User can easily change the IP of the machine, but user cannot anyhow change the hostname of the machine. To change the hostname, we need to run AutoConfig on E-Business Suite.
First, startup dbTier. AppTier is not required at all in the whole process.
FOR DATABASE TIER:
Note:338003.1 How to change the hostname and/or port of the Database Tier using AutoConfig
1. Login as oracle user.
2. De-register the current database server.
perl $ORACLE_HOME/appsutil/bin/adgentns.pl appspass=apps contextfile=$CONTEXT_FILE -removeserver
3. Update AutoConfig Context file with new host information. Edit $CONTEXT_FILE directly.
* Copy $CONTEXT_FILE to a new context file.
cp /opt/oracle/product/10.1.0/db/appsutil/PROD_<oldhost>.xml /opt/oracle/product/10.1.0/db/appsutil/PROD_<newhost>.xml
* Edit /opt/oracle/product/10.1.0/db/appsutil/PROD_<newhost>.xml directly.
- Replace all <oldhost> to <newhost>
- Replace all <olddomain.com> to <newdomain.com>
4. Change hostname.
- Execute "system-config-network" to change the new hostname for the machine.
- Edit /etc/hosts with "newhost.newdomain.com ip newhost".
(After changing hostname, you'll not be able to startup any graphical application such as xclock due to "Xlib: connection to :0.0 refused by server". You can press "ctrl + alt + backspace" to kill x server.)
5. Execute AutoConfig for dbTier.
cd $ORACLE_HOME/appsutil/bin/
./adconfig.sh contextfile=$ORACLE_HOME/appsutil/PROD_<newhost>.xml
FOR APPS TIER:
Note:341322.1 How to change the hostname of an Applications Tier using AutoConfig
1. Login as applmgr user.
2. De-register the current apps server.
perl $AD_TOP/bin/adgentns.pl appspass=apps contextfile=$CONTEXT_FILE -removeserver
3. Update AutoConfig Context file with new host information. It is easier to edit $CONTEXT_FILE directly.
* Copy $CONTEXT_FILE to a new context file.
cp /opt/oracle/apps/prodappl/admin/PROD_<oldhost>.xml /opt/oracle/apps/prodappl/admin/PROD_<newhost>.xml
* Edit /opt/oracle/apps/prodappl/admin/PROD_<newhost>.xml directly.
- Replace all <oldhost> to <newhost>
- Replace all <olddomain.com> to <newdomain.com>
4. Execute AutoConfig for appTier.
cd $AD_TOP/bin
./adconfig.sh contextfile=/opt/oracle/apps/prodappl/admin/PROD_<newhost>.xml appspass=apps
FINISHING TASK:
AutoConfig doesn't convert E-Business Suite completely. Some settings may remain unchanged or reset to default. So, it is required to go check the configuration as described in Cloning Guide.
Identified steps are:
1. As applmgr, vi /opt/oracle/apps/prodappl/admin/adgetlnxver.sh to ensure ctxfile is pointing to correct PROD_<newhost>.xml file.
ctxfile="/opt/oracle/apps/prodappl/admin/PROD_htb.xml"
2. As applmgr user, vi $IAS_ORACLE_HOME/Apache/Jserv/etc/jserv.properties to ensure:
wrapper.bin.parameters=-Djava.awt.headless=true
wrapper.bin.parameters=-DAdaptorCatalog=/opt/oracle/apps/prodappl/au/11.5.0/java/catalog.xml
wrapper.bin.parameters=-DClientMode=local
3. As oracle user, do the following:
$ sqlplus apps/apps
sql> update icx_parameters set session_cookie_domain='newdomain.com';
sql> conn applsys/apps
sql> select profile_option_value from fnd_profile_option_values where profile_option_value like '%oldhost%';
sql> update fnd_profile_option_values set profile_option_value='/opt/oracle/db/proddb/9.2.0/appsutil/outbound/PROD_newhost' where profile_option_value like '%oldhost%';
3 rows will be updated.
sql> exit;
Done. You can startup AppTier now and access E-Business Suite login page at http://newhost.newdomain.com:8000.

How to Change IP, Hostname, Domain and Ports of a single node Oracle E-Business Suite
Oracle E-Business Suite is not dependent to IP address, so one can easily change the IP address of nodes without any effect on E-Business Suite.
What about Hostname, Domain and Ports? Oracle E-Business Suite is dependent to these. So, we couldn’t change theme without coordination of E-Business Suite itself.
There are two methods for changing Hostname, Domain and Ports of Oracle E-Business Suite. The first method, that will be discussed here, is using autoconfig and another method is by cloning. It is easier to use autoconfig method to change hostname, domain and ports and use cloning method for changing other configurations of Oracle E-Business Suite.
In this document we assume that our E-Business Suite has just one node so that all Tiers and Servers reside on this node. For changing hostname, domain and ports of a multinode Oracle E-Business Suite, refer to the documents listed in the refrences section of this post.
1. DB Tier: Deregister the current database server
As the database hostname and domain will be changed, the current database server node needs to be de-registered.
SQL> select NAME, SERVER_TYPE from FND_APP_SERVERS, FND_NODESwhere FND_APP_SERVERS.NODE_ID = FND_NODES.NODE_ID andSERVER_TYPE='DB' and FND_NODES.NODE_NAME=UPPER('oldhost');
NAME SERVER_TYPE
--------------- -----------
oldhost_PROD_DB DB
# cd $ORACLE_HOME/appsutil
# perl ./bin/adgentns.pl appspass=<APPSpwd> contextfile=./PROD_oldhost.xml -removeserver
SQL> select NAME, SERVER_TYPE from FND_APP_SERVERS, FND_NODESwhere FND_APP_SERVERS.NODE_ID = FND_NODES.NODE_ID andSERVER_TYPE='DB' and FND_NODES.NODE_NAME=UPPER('oldhost');
no rows selected
2. DB Tier: Create a new Context file
You can create the new context file using whichever of the following methods:
a. Manuall Method:
# cd $ORACLE_HOME/appsutil
# cp PROD_oldhost.xml PROD_newhost.xml
Edit PROD_newhost.xml manually:
Replace all oldhost with newhost
Replace all olddomain with newdomain
b. Script Method:
# cd $ORACLE_HOME/appsutil
# perl ./bin/adclonectx.pl contextfile=./PROD_oldhost.xml
Provide the values required for creation of the new Database Context file.
Do you want to use a virtual hostname for the target node (y/n) [n] ?:

/gldb/apps/d02/oracle/proddb/9.2.0/appsutil/PROD_newhost.xml
Note: The command above will create a new Context file of the format PROD_newhost.xml in the current working directory.
3. APPS Tier: Deregister the current Applications server
As the Applications hostname and domain will be changed, the current Applications server node needs to be de-registered.
SQL> select NAME, SERVER_TYPE from FND_APP_SERVERS, FND_NODESwhere FND_APP_SERVERS.NODE_ID = FND_NODES.NODE_ID andSERVER_TYPE='APPS' and FND_NODES.NODE_NAME=UPPER('oldhost');
