1 Alarm Description
The alarm is raised when the Data Access Service (DAS) cannot establish or re-establish the database connection.
DAS continuously tries to re-establish the connection to the database server. If it succeeds, the alarm ceases automatically.
The alarm ceases if the DataService is set to LOCKED but that does not fix the problem indicated by the alarm.
Table 1 lists alarm causes.
