Replica Synchronization

Use this page to view the synchronization status of a replica. You can use the links on this page and in the navigation bar on the left to access other partitions and jump through your replica ring.

Partition Synchronization Status

Partition
Links to detailed object information for the partition.

Last Successful Sync
Lists the amount of time since all replicas of an individual partition were successfully able to synchronize from this server.

Maximum Ring Delta
Lists the amount of data which might not be successfully synchronized to all the replicas in the ring. For example, if a user has changed his or her login script within the past 30 minutes, and the maximum ring delta has a 45-minute allocation, the user's login might not be successfully synchronized, and he or she might get the previous login script when he or she attempts to log in. However, if the user changed the login script more than 45 minutes ago, he or she should get the new login script consistently from all replicas.

If Unknown is listed under the Maximum Ring Delta, then the transitive synchronized vector is inconsistent and the maximum ring delta cannot be calculated because of a problem, such as replica/partition operations in progress.

Replica's Perishable Data Delta
Lists the amount of data on the partition which has not been successfully replicated yet and which would be lost if the server went down immediately.

Replica Status
Lists the server, replica state and number, last successful synchronization, and the replica's send and receive deltas.

Server
Lists replica types and the servers they are stored on for the partition. Also allows you to link to detailed object information for each server.

Replica State
Lists the current state of a partitioning operation of the replica.

Replica Number
Lists the unique identifier of the replica. The number is assigned upon creation.

Last Successful Sync
Lists the date and time that the replica was successfully able to synchronize on this server.

Send Delta
List the amount of data that has yet to be replicated to other servers.

Receive Delta
Lists the amount of data waiting to be received from another server.
