OVD 11g Quick Tips

Finding OVD version :-
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

10 and change it to 50 

do it for "Admin Gateway", "LDAP Endpoint" and "LDAP SSL Endpoint".
