Oracle Applications Manager - Version 12.0.6 to 12.1.3 [Release 12 to 12.1]
Information in this document applies to any platform.

GOAL
Oracle E-Business Suite is dependent to hostname and domain. Assume that E-Business Suite has just one node so that all Tiers and Servers reside on this node. Please refer to following to modify the hostname on EBS R12.
For Windows EBS server users, that have to open a command window and source the mks Enviroenment to be able to execute below Unix commands.
SOLUTION
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.
select NAME, SERVER_TYPE
from FND_APP_SERVERS, FND_NODES
where FND_APP_SERVERS.NODE_ID = FND_NODES.NODE_ID
and SERVER_TYPE='DB'
and FND_NODES.NODE_NAME='old_hostname';
NAME SERVER_TYPE
--------------- -----------
oldhost_<SID>_DB DB
Executing following commands to deregister the current database server:
cd $ORACLE_HOME/appsutil
perl ./bin/adgentns.pl appspass=<APPSpwd> contextfile=./<SID>_oldhost.xml -removeserver
select NAME, SERVER_TYPE
from FND_APP_SERVERS, FND_NODES
where FND_APP_SERVERS.NODE_ID = FND_NODES.NODE_ID
and SERVER_TYPE='DB'
and FND_NODES.NODE_NAME='old_hostname';
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. Manual Method:
cd $ORACLE_HOME/appsutil
cp <SID>_oldhost.xml <SID>_newhost.xml
Edit <SID>_newhost.xml manually:
Replace all oldhost with newhost
b. Script Method:(The command below will create a new Context file of the format <SID>_newhost.xml in the current working directory.)
cd $ORACLE_HOME/appsutil
perl ./clone/bin/adclonectx.pl contextfile=./<SID>_oldhost.xml

It is recommended that your inputs are validated by the program.
However you might choose not to validate them under following circumstances:
-If cloning a context on source system for a remote system.
-If cloning a context on a machine where the ports are taken and
you do not want to shutdown the services at this point.
-If cloning a context but the database it needs to connect is not available.

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.
select NAME, SERVER_TYPE
from FND_APP_SERVERS, FND_NODES
where FND_APP_SERVERS.NODE_ID = FND_NODES.NODE_ID
and SERVER_TYPE='APPS'
and FND_NODES.NODE_NAME='old_hostname';
NAME SERVER_TYP
----------------- ----------
oldhost_<SID>_APPS APPS
Executing following commands to deregister the current Applications server:
cd $APPL_TOP/admin
perl $AD_TOP/bin/adgentns.pl appspass=<APPSpwd> contextfile=./<SID>_oldhost.xml -removeserver
select NAME, SERVER_TYPE
from FND_APP_SERVERS, FND_NODES
where FND_APP_SERVERS.NODE_ID = FND_NODES.NODE_ID
and SERVER_TYPE='APPS'
and FND_NODES.NODE_NAME='old_hostname';
no rows selected.
4. APPS Tier: Create a new Context file
You can create the new context file using whichever of the following methods:
a. Manual Method:
cd $APPL_TOP/admin
cp <SID>_oldhost.xml <SID>_newhost.xml
Edit <SID>_newhost.xml manually:
Replace all oldhost with newhost
b. Script Method:(The command below will create a new Context file of <SID>_newhost.xml in new <SID>_newhost directory.)
cd $INST_TOP/appl/admin
perl $COMMON_TOP/clone/bin/adclonectx.pl contextfile=./<SID>_oldhost.xml

5. APPS Tier: Shutdown the Application Tier Services
cd $INST_TOP/admin/scripts
./adstpall.sh apps/<appspasswd>
6. Change the server machine hostname.
Please contact your IT administrator to change the machine hostname.
7. DB Tier: Reseed the Net Services Topology Model
cd $ORACLE_HOME/appsutil
./bin/adconfig.sh contextfile=./<SID>_newhost.xml
8. APPS Tier: Reseed the Net Services Topology Model
The Net Services Topology Model is automatically updated by running AutoConfig.
$AD_TOP/bin/adconfig.sh contextfile= $INST_TOP/../<SID>_newhost//appl/admin/<SID>_newhost.xml appspass=<appspasswd>
