CPU overload protection on the Oracle Communications Core Session Manager is system-oriented in terms of defining the percent utilization that triggers an action. Actions are application-specific.

For the Oracle Communications Core Session Manager application, if the CPU usage exceeds the configured setting, the system sends a 5xx error in response to any initial dialog request or standalone transactions. The Oracle Communications Core Session Manager continues to accept registration refreshes and new transactions within a dialog.

By default the CPU utilization rate is 80%. This value can be changed by the following ACLI command sequence.

ORACLE# configure terminal
ORACLE(configure)# session-router
ORACLE(session-router)# sip-config
ORACLE(sip-config)# +options load-limit=”70”
ORACLE(sip-config)# done
