Listener metric in Enterprise Manager
Dear gurus,
Need your advice, in Enterprise Manager there is tnsping response time which shows the response time of listener in target db.
My question is, this response time comes from tnsping to target db but from where ? is it tnsping from OEM Server to target DB or from agent which installed on Target DB machine to listener which reside on target db also ?
I need this because in OEM, the response time shows good status, below threshold (I give 30ms for warning threshold). but from application servers they got intermittent connection to listener target DB while apps guy tried to tnsping.
