EvTrNoRespClose

Measurement Group: Association Exception

Measurement Type: Simple

Description: The number of times the association was closed due to lack of response from the far end. This includes lack of response to any signaling sent on the association or to SCTP heartbeating if enabled.

Collection Interval: 30 min

Peg Condition: This measurement is incremented by one each time an established SCTP association 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. This measurement should have a zero value. If it has a non-zero value, the association has been closed due to the lack of response from the far-end. The MP server will begin periodic attempts to reconnect to the signaling gateway. You can view the Association status from the GUI main menu under SS7/Sigtran>Maintenance>Associations.
  2. Look in the event history from the GUI main menu under Alarms & Events>View History for Event ID 19225.
  3. Verify IP connectivity between the MP server and the signaling gateway.
  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 signaling gateway for excessive retransmissions.
  6. Contact My Oracle Support (MOS) for assistance if needed.
