Oracle E-Business Suite uses three OC4J (oacore, oafm & forms) for Java Applications including Forms and HTTP Server for static HTML content.
All these four components are managed (including startup/shutdown) by OPMN (Oracle Process Manager & Notification) .
A. Script to start/stop OPMN in R12 – $ADMIN_SCRIPTS_HOME/ adopmnctl.sh
B. Script to start/stop HTTP Server in R12 – $ADMIN_SCRIPTS_HOME/ adapcctl.sh
C. Script to start/stop oacore OC4J in R12 – $ADMIN_SCRIPTS_HOME/ adoacorectl.sh
D. Script to start/stop oafm OC4J in R12 – $ADMIN_SCRIPTS_HOME/ adoafmctl.sh
E. Script to start/stop forms OC4J in R12 – $ADMIN_SCRIPTS_HOME/ adformsctl.sh

How to troubleshoot status code 204 Issue for OC4J ?
1. First check startup log at $LOG_HOME/appl/admin/log/ adoacorectl.txt, adoafmctl.txt, adoaformsctl.txt
2. Next check log at $LOG_HOME/ ora/ 10.1.3/ opmn/ opmn.log

09/07/22 18:28:10 [libopmnoc4j] Port information in the ONS notification is incorrect for proc: 1154637034. Some of the reasons for the failure are:
1. ajp, rmi and jms ports could not be bound by the process.
2. If a port value for a certain port ID is handed by OPMN to the OC4J process and this value is not returned back in the ONS notifications. For example, this can happen for certain bad JGroups related configurations.

Fix
Clear directory under persistence from below directory and restart all three OC4J
$ORA_CONFIG_HOME/ 10.1.3/ j2ee/ oacore/ persistence
$ORA_CONFIG_HOME/ 10.1.3/ j2ee/ oafm/ persistence
$ORA_CONFIG_HOME/ 10.1.3/ j2ee/ forms/ persistence
This could be because of .lock files and explained in Metalink Note 372412.1 OC4J Fails to startup with “ERROR Failed to set the internal configuration of the OC4J JMS Server”
.
3. If all services are up and running and you still get “Page not found” in Apps R12, then
Check logs in $LOG_HOME/ora/10.1.3/opmn/oacore_default_group_1/oacorestd.err

Fix : There are two potential solution (or more depneding on root cause of JOC issue)
1. Check if not other service is using JOC port (JOC port is defind by parameter s_java_object_cache_port in context file), run Autoconfig and test again
2. Disable JOC by changing s_long_running_jvm in context file from true to false and run Autoconfig
