SnTT: Notes Mail “Inbox Maintenance”

This feature,  introduced with Notes/Domino 8.0, will “clean-up” user mail Inbox folders. In other words, it removes ( not deletes ) documents from the Notes/Domino mail Inbox. The goal is to improve server performance by reducing user mail Inbox size. An Inbox folder with fewer documents performs better because it has fewer documents to index and replicate.

Frequently asked questions are answered in this FAQ. One of the questions is about how the feature works in a mixed environment with 7.x and 8.x mail templates.

The FAQ says that Inbox Maintenace only works with 8.x mail templates. But it is very easy to even enable a 7.x mail template.

The only thing you have to do is to copy the LotusInboxCleanup agent from mail8.ntf to your 7.x template.

The server looks for the existance of the agent and triggers it  if available. Otherwise it will skip databases that do not inherit the agent.

Although the agent is of type scheduled, you do not have to setup a schedule. The agent is invoked by the server.

Settings are on the “Server Tasks -> Administration process” tab of the server document.


Impressive DAOS results

I recently ran daosest 1.1 on one of our production server.  The test took almost 48 hours. Here are the results.

Total DB’s analyzed: 957
Total DB’s skipped due to errors: 0
Total Size of NSF’s Examined: 1023.8 GB
Total Attachments found: 3070488
Total Duplicate Attachments found: 2084628
Total DAOS Eligible Attachments: 3070488
Estimated Size of DAOSified NSF’s: 89.6 GB
Estimate Size of DAOS dir: 335.0 GB
Total Disk Savings: 636.8 GB

I am really impressed. Never expected the calculated total disk savings.

If you want to use DAOS in a clustered environmen, here is some information by Paul Mooney.
