Checking Replication Status
For performance monitoring purposes, you should check replication status periodically. This task enables you to view actively updated information such as a list of the servers that hold content replicas of the specific public folder, the replication status of each server, the last time a replication message was received, and the average transmission time.
For detailed steps about how to check replication status, see How to Check Public Folder Replication Status.
The following table lists a number of additional time-outs and settings that control public folder replication. Values that you can modify are noted in the table. Other values are for reference only. This information can help you to troubleshoot replication issues, especially if replication seems to take an unusual length of time.
Default time-outs and intervals that Exchange Server 2003 uses during replication
| Replication event | Default time-out | Description |
|---|---|---|
Replication Expiry |
24 hours |
The frequency with which the public folder store checks folders for expired information. |
Replication Send Always |
15 minutes |
The default Replicate Always value, indicating how often the store checks to see whether it needs to replicate content. Can be adjusted using Exchange System Manager. |
Replication Send Folder Tree |
5 minutes |
The frequency with which the store checks to determine whether it should send a hierarchy replication message. |
Replication Send Status Timeout |
24 hours |
The frequency with which the store checks to determine whether it should send a status message for a folder. |
Replication Timeout |
5 minutes |
The frequency with which the store checks to determine whether any backfill time-outs have expired. |
Replication New Replica Backfill Request Delay |
15 minutes |
The length of time that the store delays before it sends a backfill request for a new folder replica when the data is available in the same Exchange routing group. |
Replication Short Backfill Request Delay |
6 hours |
The length of time that a store delays before sending a backfill request for data that is available in the same Exchange routing group. |
Replication Long Backfill Request Delay |
12 hours |
The length of time that a store delays before sending a backfill request for data that is not available in the same Exchange routing group. |
Replication Short Backfill Request Timeout |
12 hours |
The time-out value that a store uses when trying to send a backfill request for data that is available in the same Exchange routing group. |
Replication Long Backfill Request Timeout |
24 hours |
The time-out value that a store uses when trying to send a backfill request for data that is not available in the same Exchange routing group. |
Replication Short Backfill Request Timeout Retry |
24 hours |
The time-out value that a store uses when sending a backfill request for data that is available in the same Exchange routing group, and when this request is a retry of a previous backfill request. |
Replication Long Backfill Request Timeout Retry |
48 hours |
The time-out value a store uses when sending a backfill request for data that is not available in the same Exchange routing group, and when this request is a retry of a previous backfill request. |
