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 displays the login ID of the current lock holder and the duration of the lock to the nearest second. The lock automatically expires after a configurable number of minutes or the lock holder can click the Unlock' link in the navigation column to instantly release the lock. To obtain the lock, the administrator must click the Get Lock link in the navigation column or perform any operation which causes an update to the database. Once the lock is obtained, the lock timer begins. Each update operation performed resets 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.
