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

  2. Hi,

    Yes I suppose this will work. In our case we made an master Virtual machine that we clone to a new virtual machine and we did the steps in the blog.

    The application server is working fine! So a tar should work also.

    Kind regards,

    Arjan

  5. This blog was for 10.1.3.x for the 10.1.2 infra this is not so easy because of the metadata repository. I do not have any experience with this version and changing ip addresses.

  7. Hello

    Nice blogs... lots of good information here...

    I had a comment on Portal 10.1.4. since there was no comments section there i am putting it here. Sorry abt this...

    We use portal 10.1.4 and we are having issues doing an export/import of the personalizations. the personalizations of the WSRP portlets gets lost during the import. If we customize it in say region A (default) and i move it to tab B. After we do an import the portlet goes bak to A tab.

    Is there anything that we are missing interms of setup etc?
