LDAP: error code 34 - Invalid root DN given : cn=oracledbconnections,null

This issue occurs when we try to connect OracleAQ via  Oracle JMS. To overcome above issue, check whether you have set following property,
    env.put(AQjmsConstants.SERVER_DN, "cn=ORCL,cn=OracleContext,ou=Services, o=sgi,c=us");

The second parameter provides the DN value of "ORCL", which is the third level, labeled cn=orcl, is the database.
