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.   B u t Ho s tn a m e , Do m a i n a n d P o r ts a r e n o t l i k e th a t, Or ac ac l e E - B u s i n e s s S u i te i s d e p e n d e n t to th e s e its e l f.   entries. So, we couldn’t change these values without co - o r d i n a ti o n o f E - B u s i n e s s S u i te its

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/apps SQL> SQL> 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=UPPER('oraapps');   NAME SERVER_TYPE  ---------------------------- -----------  oraapps DB  SQL> SQL> exit $ $ $ cd $ORACLE_HOME/appsutil   $ perl ./bin/adgentns.pl appspass=apps contextfile=./vis_oraapps.xml -removeserver   $ $ sqlplus apps/apps SQL> SQL> 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=UPPER('oraapps');   no rows selected  2. Create a new Context file  

$ cd $ORACLE_HOME/appsutil   $ perl ./bin/adclonectx.pl contextfile=./vis_oraapps.xml   <Enter the corresponding values for the prompts>   The new database context file has been created :    /u01/VIS/db/tech_st/11.1.0/appsutil  /u01/VIS/db/t ech_st/11.1.0/appsutil/vis /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 cur rent 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/apps SQL> SQL> 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=UPPER('oraapps');  NAME SERVER_TYPE  -------------------------------- -------------------  oraapps APPS  SQL> SQL> exit $ $ $ cd $APPL_TOP/admin  $ perl $AD_TOP/bin/adgentns.pl appspass=apps contextfile=./vis_oraapps.xml -removeserver   $ sqlplus apps/apps SQL> SQL> 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=UPPER('oraapps');  no rows selected  2. Create a new Context file   $ cd $APPL_TOP/admin 

$ perl $AD_TOP/bin/adclonectx.pl contextfile=./vis_oraapps.xml  Provide the values required for creation of the new APPL_TOP Context file.  

<Enter the corresponding values for the prompts>   The new context file has been created :    /u02/VIS/apps/apps_st/appl/vis  /u02/VIS/apps/apps_st /appl/vis _neworaapps.xml  

Note: The command above will create a new Context file of the format sid_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.com oraapps  # NEW Address 192.169.10.26 neworaapps.yemensoft.net neworaapps -- change the current host-name as follows on all corresponding hosts   # hostname <new_host_name>  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 Model  

The 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 On APPS 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.
