This is not officially supported, but it worked for me. First go get the “rpl” rpm, then use;
# Script to change the node name of the appgold server to the cloned host name.
# First lets change all the directory names
server=`hostname`
find /opt/WebSphere/AppServer -type d -name *old_node_name* -print | while read directory
do
newname=`echo $directory | sed ‘s/old_node_name/’$server’/g’`
mv $directory $newname
done
# Now lets change all the file contents using rpl
cd /opt/WebSphere/AppServer
/usr/local/bin/rpl -R old_node_name $server *
**NOTE ** You might have to run this twice to catch all the subdirectories.
