ADMINISTERING
Before setting up attachment consolidation on a Domino® server by enabling the Domino Attachment and Object Service, decide where to place files and how large files should be before consolidation. On each server that uses attachment consolidation, you specify the directory where you want to create the resulting repository of shared file attachments. If the number of DAOS (.NLO) files in the directory becomes too large for your operating system limit, Domino creates additional subdirectories as needed.
About this task
The attachment repository, by default, is created relative to the logical directory structure that is controlled by the server. You can create the directory anywhere on the server or a connected file drive by specifying a full path.
For information on use an S3-compatible storage service to store older attachment objects that haven't been accessed within a specified number of days, see DAOS tier 2 storageStarting in Domino 11, the Domino Attachment Object Service (DAOS) tier 2 storage feature enables you to use an S3-compatible storage service to store older attachment objects that haven't been accessed within a specified number of days. This feature allows you to reduce the amount of data stored on Domino servers that use DAOS. It can also improve the performance of any incremental file backups that you do for DAOS. .
To set up and enable the Domino Attachment and Object Service
Procedure
1. Make sure that transaction logging is enabled on the Domino server.
2. From the Domino Administrator, click the Configuration tab and then expand the Server section.
3. Select the Server document to be edited and then click Edit Server.
4. Click the DAOS tab.
5. Enable or disable the use of attachment consolidation by completing first field in the following table. If enabling, complete all the remaining fields.
Consolidating attachments of very small size is not worth the processing effort because it does not yield much disk space saving.
Important: Despite the default, it is highly recommended that you specify a full path outside of the Domino data directory.
Example on Microsoft™ Windows™:
Note: Make sure that the Domino administrative user has file-access permissions in the directory appropriate to the server's operating system.
Enter a number from 0 to 9999.
This setting is useful if an unreferenced DAOS object is mistakenly deleted and needs to be restored.
You can delete all unreferenced objects explicitly at any time by using the Tell DAOSMgr Prune command.
What to do next
If the server runs virus detection software, use the same virus scan policy for the DAOS directory as is set for .NSF files in the server data directory.
To put the new configuration into effect, restart the server.
