Open file ..../Oracle/Middleware/OVD_INST_1/config/OVD/ovd1/server.os_xml .
Look for section "OVD_INST_1_OVD" .
Setting OVD Log (Alternative to console) :-
You can set OVD log level directly using console UI. But, you may get an error "JAVAX.EL.ELEXCEPTION: JAVA.LANG.NULLPOINTEREXCEPTION AT JAVAX.EL.BEANELRESOLVER" because of an OVD 11.1.1.5 bug while doing it from em console.
Here is an alternative approach Doc
1. Stop OVD :
$ORACLE_INSTANCE/bin/opmnctl stopproc ias-component=ovd1
2. Open $ORACLE_INSTANCE/config/OVD/ovd1/ovd-logging.xml change such as to have
<loggers>
<logger name='com.octetstring.vde' level='TRACE:32' useParentHandlers='false' >
<handler name='OVDHandler'/ >
</logger >
<logger name='com.octetstring.accesslog' level='TRACE:32' useParentHandlers='false' >
<handler name='OVDAccessHandler'/ >
</logger >
</loggers>
3. Start OVD: $ORACLE_INSTANCE/bin/opmnctl startproc ias-component=ovd1
Setting Worker Tread :-
Does your OVD error log (.../ovd_inst/diagnostics/logs/OVD/ovd1/http-errors.log) shows occasional error message called “Low on Thread” or “Out of thread”. Check $OVD_HOME/config/OVD/listeners.os_xml for at least
50 worker threads in the LDAP listener.
look for entry
do it for "Admin Gateway", "LDAP
Endpoint" and "LDAP SSL Endpoint".
