Problem Description

When changing a MGW status using the change command, the system behavior can be inconsistent. It may result in database mismatches where the MGW status differs between the Element Management System (EMS) and the CA.

Background

The change command is intended and designed to be used to modify provisioned data. The control command is intended and designed to be used for administrative status changes.

The BTS CLI allows users to use the change command to modify the MGW state.

Example:

change mgw id=c5400_162; STATUS=INS

Using the change command to update MGW status can result in inconsistent data.

Problem Symptoms

When performing an audit such as:

CLI> audit database type=full

The following error (example) may be observed.

Auditing table TERMINATION on [CA146] 
..................... 
DATABASE MISMATCH FOUND IN TERMINATION WHERE ID='aaln/1' and MGW_ID= c5400_162' 
EMS DATABASE: STATUS=OOS 
CA146 SHARED MEMORY: STATUS=INS

Workaround/Solution

Users should update MGW status using the control command

Example:

control mgw id=c5400_162; mode=forced; target-state=INS

Starting in Release 4.5 the BTS will no longer allow the use of the change command to update MGW status.
