The DB_RESTORE_FAIL alarm indicates that service restoration fails due to failed access to the database. When starting to work, the NE software attempts to gain access to the associated database for restoring services. This alarm is reported if service restoration fails because the NE software finds that some database files are lost or damaged.

Impact on the System

All service configurations are lost and no new service can be configured.

Possible Causes

The possible cause of the DB_RESTORE_FAIL alarm is as follows:

Database files are lost or damaged.


  1. Back up the database files in which are lost or damaged.


    This operation helps to analyze and find the database error cause.

  2. Delete the database and reset the NE software.
  3. Obtain correct database files that are backed up most recently and apply service configurations again to clear the alarm.


    The database is not backed up in real time. Therefore, the applied service configurations may be different from those before this problem occurs. Configure the services that have been impaired to completely restore the services.
