Synchronizing replicas of a database
First Claim
Patent Images
1. A computer-implemented method for synchronizing replicas of a database, the method comprising:
- detecting a failure of update data from a first replica of the database at a first server site to be applied to a second replica of the database at a second server site;
determining a cause of the failure;
resolving the cause of the failure by deleting an object if the cause of the failure is due to the object not being deleted during a previous export; and
automatically, without manual intervention, sending the update data to the second replica of the database at the second server site after the cause of the failure is resolved.

Abstract
Replicas of a database are synchronized. A failure of update data is detected from a first replica to be applied to a second replica. A cause of the failure is determined. The cause of the failure is resolved. The replicas of the database are synchronized without requiring manual intervention.

12. A computer readable medium containing program instructions for synchronizing replicas of a database, the program instructions which when executed by a computer system cause the computer system to execute a method comprising:
-
detecting a failure of update data from a first replica of the database at a first server site to be applied to a second replica of the database at a second server site; determining a cause of the failure; resolving the cause of the failure by deleting an object if the cause of the failure is due to the object not being deleted during a previous export; and automatically, without manual intervention, sending the update data to the second replica of the database at the second server site after the cause of the failure is resolved. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A database system comprising:
-
a first server site comprising a first replica of a database; a second server site coupled to the first server site, the second server site comprising a second replica of the database; and a client coupled to the first replica wherein the client detects a failure of update data from the first replica to be applied to the second replica, wherein the client further determines a cause of the failure and resolves the cause of the failure by deleting an object if the cause of the failure is due to the object not being deleted during a previous export, wherein the client automatically, without manual intervention, sending the update data to the second replica of the database at the second server site after the cause of the failure is resolved. - View Dependent Claims (24, 25, 26, 27, 28)
