EvTrNoRespClose

Measurement Group: Transport Exception

Measurement Type: Simple

Measurement Dimension: Arrayed (per Transport)

Description: The number of times the transport was closed due to lack of response from the far end, including lack of response to any signaling sent on the transport.

Collection Interval: 30 min

Peg Condition Each time an established Transport is closed by the MP server due to lack of response at the SCTP level from the far-end of the association

Measurement Scope: NE, Server

Recovery:

  1. If all is well, this measurement should have a zero value. If non-zero, the association has been closed due to lack of response from the far-end. The MP server will begin periodic attempts to reconnect to the SG.
  2. Otherwise:
    1. Transport status can be viewed at Main Menu > Transport Manager > Maintenance > Transport.
    2. Look in the event history at Main Menu > Alarms & Events > View History Event 19405 - Transport closed due to a lack of response (refer to the DSR Alarms and KPIs Reference for details about this event.
    3. Verify IP connectivity between the MP server and the SG.
    4. Determine if the far-end of the association is congested, possibly causing slow response times on the association.
    5. Check the IP network between the MP server and the SG for excessive retransmissions.
    6. Contact My Oracle Support (MOS) for assistance if needed.
