How to change IP address, host-name and port

Oracle E-Business Suite is not dependent on IP address, so one can easily change the IP address of nodes without any effect on E-Business Suite.But Hostname, Domain and Ports are not like that, Oracle E-Business Suite is dependent to these entries. So, we couldnt change these values without co-ordination of E-Business Suite itself.

Primary idea was to just change the IP Address but I will also describe how to change host-name and port as well.

There are two methods from which one can choose

1. Use Auto-Config 2.Cloning

On DB Tier:

1. De-register the current database server (Required)

As the database IP address, hostname and domain will be changed, the current database server node needs to be de-registered. To deregister the current database server node, run the following command as the owner of the Oracle RDBMS file system and current database instance:

# su - oracle$ sqlplus apps/appsSQL>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('oraapps');

NAME SERVER_TYPE--------------- -----------oraapps DBSQL> SQL> exit$$$ cd $ORACLE_HOME/appsutil$ perl ./bin/adgentns.pl appspass=appscontextfile=./vis_oraapps.xml -removeserver$$ sqlplus apps/appsSQL>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('oraapps');

2. Create a new Context file

$ cd $ORACLE_HOME/appsutil$ perl ./bin/adclonectx.plcontextfile=./vis_oraapps.xml

The new database context file has been created :/u01/VIS/db/tech_st/11.1.0/appsutil/vis_neworaapps.xml

Note: The command above will create a new Context file of the format sid_hostname.xml in the current working directory.

On APPS Tier:

1. De-register the current Applications server

As the Applications IP address, hostname and domain will be changed, the current Applications server node needs to be de-registered.To deregister the current Applications server node, run the following command as the owner of the Oracle Applications file system and current database instance:

# su - applmgr$ sqlplus apps/appsSQL> SQL> select NAME, SERVER_TYPE from FND_APP_SERVERS, FND_NODES where FND_APP_SERVERS.NODE_ID = FND_NODES.NODE_ID andSERVER_TYPE='APPS' and FND_NODES.NODE_NAME=UPPER('oraapps');

NAME SERVER_TYPE----------------- ----------oraapps APPSSQL> SQL> exit$$$ cd $APPL_TOP/admin$ perl $AD_TOP/bin/adgentns.pl appspass=apps contextfile=./vis_oraapps.xml -removeserver

$ sqlplus apps/appsSQL>SQL> select NAME, SERVER_TYPE from FND_APP_SERVERS, FND_NODES where FND_APP_SERVERS.NODE_ID = FND_NODES.NODE_ID andSERVER_TYPE='APPS' and FND_NODES.NODE_NAME=UPPER('oraapps');

no rows selected

2. Create a new Context file$ cd $APPL_TOP/admin$ perl $AD_TOP/bin/adclonectx.pl contextfile=./vis_oraapps.xmlProvide the values required for creation of the new APPL_TOP Context file.

The new context file has been created :/u02/VIS/apps/apps_st/appl/vis_neworaapps.xml

Note: The command above will create a new Context file of the formatsid_hostname.xml in the current working directory.

3. Shutdown the Application Tier Services

# su - applmgr$ cd $ADMIN_SCRIPTS_HOME$ ./adstpall.sh apps/apps

4. Change the hostname and domain

Change the hostname and domain at OS level.

# edit /etc/hosts as follow:# OLE 192.168.1.111 oraapps.yemensoft.comoraapps# NEW Address192.169.10.26neworaapps.yemensoft.netneworaapps

-- change the current host-name as follows on all corresponding hosts

# hostname

Check the following files for correct values on all nodes-/etc/sysconfig/network (for host-name change)-/etc/sysconfig/network-scripts/ifcfg-eth0 (for IP-Address change)If the ip address is changed then restart the network services (as root user) on all nodes#service network restart

On DB Tier: Reseed the Net Services Topology Model# cd $ORACLE_HOME/appsutil# ./bin/adconfig.sh contextfile=./visr12_appsdbnode.xml

On APPS Tier: Reseed the Net Services Topology ModelThe Net Services Topology Model is automatically updated by running AutoConfig.# $AD_TOP/bin/adconfig.sh contextfile=$APPL_TOP/admin/visr12_appsnode.xml appspass=apps

On DB Tier: Shutdown the database and listener# $ORACLE_HOME/appsutil/scripts/visr12_ie_dbnode/addbctl.sh stop# $ORACLE_HOME/appsutil/scripts/visr12_ie_dbnode/addlnctl.sh stop visr12

-- Start the listener and database# $ORACLE_HOME/appsutil/scripts/visr12_appsdbnode/addlnctl.sh start visr12# $ORACLE_HOME/appsutil/scripts/visr12_appsdbnode/addbctl.sh start

OnAPPS Tier: Start the Application Tier Services# $COMMON_TOP/admin/scripts/visr12_appsnode/adstrtal.sh apps/apps

Check the apps url to see if you can access the applications using new host:port combination.
