Administrator Interface
BlueZone Java Web Manager has a feature that will automatically lock the database when an Administrator is making changes.
In order to ensure data integrity, updates are restricted to a single Administrator at a time using a 'lock'. When an Administrator is updating the database, the application will display the Login ID of the current 'lock holder' and the duration of the lock to the nearest second. The lock will automatically expire after a configurable number of minutes, or the lock holder may click the 'Unlock' link in the navigation column to instantly release the lock. To obtain the lock, the Administrator must press the 'Get Lock' link in the navigation column, or simply perform any operation which causes an update to the database. Once the lock is obtained, the lock timer will begin. Each update operation performed will reset the lock timer.
The duration of the lock timer is specified in 'configurable.properties' file with the 'admin.lock.duration.minutes' key. Valid lock values range from 1 to 60 minutes, with a default of 3 minutes.
