• In addition to the alarm log file(s), the Alarm Manager maintains an "Alarms.db" data file for each application you create. An "Alarms.db" data file is an encrypted binary database file that maintains the current status of all alarms in the system. This file is automatically created by VTS when your application is initially run, and will therefore exist even if you do not configure any alarms for your application.
The alarm database has the following 5 fields:
• Message (either the alarm tag's Description property, or Name property),
• Priority,
• Type,
• Operator, and
• Area.
These default fields are specified in the master Config.ini configuration file as follows:
[Alarm_Manager]
KEYCOUNT = 5
KeyName = Message, 0, 80
KeyName = Priority, 1, -1
KeyName = Type, 2, -1
KeyName = Operator, 3, 32
KeyName = Area, 4, 32
The variables in the [ALARM_MANAGER] section are described in Config.ini [ALARM_MANAGER] Section Variables.
The Config.ini AlarmFileName variable enables you to change the root file name for the alarms .db file according to your needs. If it is your intent to change the root file name for the alarm database file ("Alarms.db") and the alarm log file ("Alarms.log"), you must first stop the application and delete the existing alarm log file and alarm database file from your application directory. For more information on doing so, and further customizing the behaviour of the Alarm Manager, see Config.ini [SYSTEM] Section Variables for Alarms.
You can extend the database to record additional data (for example, the application page related to the alarm); however, you must then provide the facility to enter this supplementary data for each alarm. Further information on recording additional data can be found in Config.ini [ALARM_MANAGER] Section Variables.
