Viewing Appdb Tables
The Web Supervisor (or any JACE-NP running the database service) includes an HTTP interface to its appdb. This allows you to use an ordinary browser to view the data in any table in its SQL database.
Two different indexes are provided into an appdb, they look and operate very similar. Both are described in the following sections.
•
Using the Appdb Index
•
Using the Archive Index
Note
No specific user rights are needed to access the main appdb index, apart from a valid station user account (username and password. Curiously enough, however, you must be assigned “Admin-read” privileges to access the archive index, which is a “subset.”
Alert tables store the complete history of alerts and currently unacknowledged alerts.
Event tables store the complete history of alarms and currently unacknowledged alarms.
