Change hostname, ip address of an Oracle Application Server SOA suite (chgiphost.sh)

It is possible to change the hostname ip address from a linux server where Oracle Application Server SOA suite (10.1.3.3.x) is installed.
The following steps need to be executed:
1. Stop the Oracle Application Server

opmnctl shutdown

2. Change the network linux server settings
Change hostname/ip address in /etc/hosts
Change hostname/ip address in /etc/sysconfig/network
Change ip address in /etc/sysconfig/network-scripts/ifcfg-eth0

Execute command hostname:

hostname {HOST_NAME_NEW}

3. Execute script chgiphost.sh

$ORACLE_HOME/chgip/scripts/chgiphost.sh

4. Find and replace the hostname in all the files of the ORACLE_HOME. These files can be found with the following command:

find ./ -type f -name '*' -print0  xargs -0 grep -li -e "{HOST_NAME_ORG}"

I created a script to do this for me: searchreplace

#!/bin/sh

if [ $# != 2 ];
then
  echo "Start op: $0  "
  exit 1
fi

REPLACE_WORD=${1}
WORD=${2}


for FILE in `find ./ -type f -name '*' -print0 | xargs -0 grep -li -e "${REPLACE_WORD}"`
do
  echo "In the ${FILE} the word ${REPLACE_WORD} is replaced by ${WORD}."
  cat ${FILE} | sed 's/'${REPLACE_WORD}'/'${WORD}'/g' > ${FILE}_TMP
  mv ${FILE}_TMP ${FILE}
done

exit 0

5. Start Oracle Database which is used for the SOA metadata repository and Update table ORAESB.ESB_PARAMETER en DT_OC4J_HOST:

sqlplus oraesb
update oraesb.esb_parameter 
set param_value='$HOST_NAME_NEW.$HOST_DOMAIN_NEW' 
 where param_name ='DT_OC4J_HOST';

6. Start Oracle Application Server:

opmnctl startall
