Apache error_log: mod_oc4j: request to OC4J [hostname]:[port] failed: Connect failed

I found out that the error below was caused by wrong configuration of the security provider of the application opm-public. When we changed jazn.xml in $ORACLE_HOME/j2ee/[oc4j_container]/config directory with the correct settings and that solved this problem.

  3. When we changed jazn.xml in $ORACLE_HOME/j2ee/[oc4j_container]/config directory with the correct settings...
    What were the correct settings?

  4. That depends on your LDAP/OID. Normally in the $ORACLE_HOME/j2ee/home/config/jazn.xml the correct settings are set when you configure the Security Provider in Enterprise manager.

  5. Thanks for the quick response.
    I have one more question.
    Before you updated the jazn.xml configuration file, was the problem an intermittent thing?
    We are getting the same error, but it is not a consistent thing, it only happens sometimes. When it happens the oc4j instance has to be recycled to get the application responsive again. Is this the behavior you were seeing before you made the configuration changes for the security provider?

  6. Hi Arjan,

    can you help me out on this, I get the same error on a default Soa Suite installation (10.1.3.5.0.)
    No OID/LDAP is in use. Can you explain what settings cause these errors and exactly how did you fix it?

    Thanks in advance, Rob
