Troubleshooting MOD_OC4J_0080 MOD_OC4J_0058 MOD_OC4J_0035 MOD_OC4J_0121 MOD_OC4J_0013 Errors In the HTTP Server error_log file [ID 329456.1]
The MOD_OC4J* errors basically convey that the HTTP Server (through mod_oc4j) is unable to communicate with the OC4J instance in question. Some of the possible causes are :
- 1. Internet Explorer (KeepAlive) Bug
- 2. Firewalls
- 3. Connection timeouts between HTTP Server/mod_oc4j & OC4J
- 4. OC4J instance running short on memory
- 5. OC4J JVMs loaded
- 6. Application(s) blocking up OC4J
Connection timeouts between HTTP Server/mod_oc4j & OC4J
In $ORACLE_HOME/Apache/Apache/conf/httpd.conf, increase the Timeout directive value to, say, 600 seconds. (This should be smaller than the Firewall timeout setting, if any)
In $ORACLE_HOME/Apache/Apache/conf/mod_oc4j.conf below the tag add the following:
Oc4jCacheSize 0
Oc4jConnTimeout 600 (This is again in seconds &, again, should be smaller than the Firewall timeout setting, if any)
Update the configuration as follows:
$ORACLE_HOME/dcm/bin/dcmctl updateconfig -ct ohs
$ORACLE_HOME/opmn/bin/opmnctl restartproc process-type=HTTP_Server
