the class Agent method startAgent.

     *  or started, attempts to create/start the others will be made; If
     *  at least one adaptor is started, monitoring will be "active"
     *  (Agent.isRunning() will return true).
     *
     *  @param monConfig SSOServerMonConfig structure of OpenAM configuration
     *  @return 0 (zero) if at least one of HTML/SNMP/RMI adaptors started up;
