Alarm clearing procedures

Procedure 1 Clearing the SLE701 (SLEE Health Monitor) alarm

at the alarm browser

1The SIP Application Module raises this warning alarm under one of two conditions:

•The number of application contexts (AC) available for use are inadequate for the level of traffic (in which case the administrator needs to back off the traffic or call the next level of support).

The SIP Application Module raises this alarm when AC pool use reaches or exceeds 80%. The alarm clears when use drops below 80%.

•There is an error condition that is causing ACs to be consumed at a higher than normal rate. This could be due to a myriad of things; for example, the system might be consuming RetrieveSubscriber ACs at a high rate because the database is overloaded.

Severity is MAJOR. The SLEE is a service processing environment. An AC is a unit of work within that processing
