Recovery

1. This measurement should have a zero value. You can view Link status from the GUI main menu under SS7/Sigtran > Maintenance > Links.
2. Check the event history log from the GUI main menu under Alarms & Events > View History. Look for Event ID 19229, which shows when the ASP-ACTIVE-ACK timeout occurs.
3. Verify that the far-end of the link on the SG is not undergoing maintenance.
4. Verify that the State Management ACK Timer period is not set too short.
5. Verify that the IP network between the MP server and the SG is performing up to expectations.
6. It is recommended to contact My Oracle Support for assistance if needed.
