Cause
The OC4J lock files contains the IP adress, after the ip adress change the lock files includes the wrong Ip adress which caused the OJ4J to fail

Solution
1 - open a new shell and set your apps environment

2 - cd $ADMIN_SCRIPTS_HOME

3 - adopmnctl.sh stop

4 - check if it is really down: ps -ef grep grep opm

5 - delete the following:

rm -fr $INST_TOP/ora/10.1.3/j2ee/oacore/persistence/*
rm -fr $INST_TOP/ora/10.1.3/j2ee/oafm/persistence/*
rm -fr $INST_TOP/ora/10.1.3/j2ee/forms/persistence/*

6 - adopmnctl.sh start

7 - check if the issue has been resolved: adapcctl.sh status
