1 Alarm Description

This alarm is raised when the number of Smp session establishment answered with result code too busy exceeds its corresponding configured threshold value.

The alarm is associated to the sxCcasInitTooBusy measure and Load Regulation function.

The main attributes of the alarm are the following:

2 Procedure

2.1 Handle Alarm Policy Control, Number of Sx CCAs Initial Sent Indicating Too Busy

Prerequisites

Before starting this procedure, ensure that you have read the following documents:
- For information about Handling Alarms, refer to Handling Alarms.
- For information about Load Regulation function, refer to Overload Control.
Before starting this procedure, ensure that the following tools are available:
- Ericsson Command Line Interface (ECLI).
- loadRegulationManager. For more information, refer to Overload Control User Guide.
No conditions are requires.

Steps

Check that the threshold (thresholdHigh and thresholdLow attributes of the object indicated by source alarm field before ":" character) is configured according to the needs. For more information, refer to Measurements.
Check values for CPULoad.Total and Mem.PercentUsed (refer to Measurements).
Check values for Load Regulation constraints. Modify constraint values if they are not correct. For details, refer to Overload Control User Guide.
Consider to redimension the SAPC if Load Regulation constraints values are properly configured.
If the alarm does not cease, consult the next level of maintenance support. Further actions are outside the scope of this procedure.
