Feature Changes
SaMOG Session Recovery Support
With this release, SaMOG has the ability to recover fully created sessions in the event of process level or card level
failures. This feature supports the following types of session recovery:
failures. This feature supports the following types of session recovery:
Task level recovery: SaMOG sessions are recovered when a Session Manager task serving the session is
terminated due to a software error.
Card level recovery: SaMOG sessions are recovered when the entire PSC/DPC card hosting the Session
Manager fails, and all the tasks running on that card have to be recovered.
When the Session Recovery feature is enabled using the CLI, the Session Manager maintains a backup of the session
critical information with the AAA Manager that has the same instance number. A paired AAA Manager with the same
instance number as the Session Manager is started on a different PSC/DPC card. When a failure is detected, the Call
Recovery Record (CRR) that contains the backed up information is fetched from the AAA Manager, and the sessions
are re-created on the recovered Session Manager.
