Domino 10 - Synchronize Database Replicas - New Option Replicate Command

This last blog post concerning the new IBM Domino 10 Administrator features  is meant purely for my own documentation in case I need the new replicate command in the near future. In IBM Domino 10 there is a new option for the Replicate command for Domino Administrators, -F, to force a full database replication when replicas of a database get out of sync. The replication takes place on the side and allows users to continue to see replication updates during the full replication. Administrators can use  the -L argument to log information about the documents (notes) that would replicate if the new option -F is used but without actually performing the replication. Until now the only option for Administrators to perform a full replication of content was by clearing the replication history. Be aware that for large databases a full replication can take time and delay the replication of new updates until it is complete. For example if the replication history of a mail file is cleared the mail user might not see new mail until the full replication completes.

To force a full replication Administrators can now use the following server command: replicate <server> <database> -F.
Example: replicate MS-DOMINO10/ALM mail\jdomino.nsf -F

Administrators can use the -L option to log details about the documents (notes) that would replicate if the -F option is used but without actually performing the replication. For example: replicate MS-DOMINO10/ALM mail\jdomino.nsf -L

Since I currently not have any replica's out of sync I don't get all the output as mentioned in the IBM documentation as shown below. Based on the new replicate command -F and the -L option to log details the output will look something like this on the Domino console.

Another great new IBM Domino 10.0 Administrator feature. In my next blog post more about advanced search capabilities and query definitions in Notes databases using LotusScript.
