Lotus Domino Administrator 8.5 Help - Specifying server settings for attachment consolidation

DATABASE MANAGEMENT

Specifying server settings for attachment consolidation
Before setting up attachment consolidation on an IBM® Lotus® 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.

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.

To set up and enable the Domino Attachment and Object Service:

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 the following fields:

Field name Enter

Store file attachments in DAOS Choose one:

Enabled. The server consolidates attachments saved in any document in any database included in consolidation. A database is included when the database property "Use Domino Attachment and Object Service" is selected.
Disabled. The server stops using attachment consolidation and any new attachments in participating databases are stored in documents.

6. Complete the following fields and then click Save & Close:

Field name Enter

Minimum size of object before Domino will store in DAOS The minimum total size, in bytes, of any attachment to be consolidated (the default is 4096 bytes). Enter a number .
Consolidating attachments of very small size is not worth the processing effort because it does not yield much disk space saving.

DAOS base path The relative or full path to the attachment repository.
For example, if you enter

DAOS

The DAOS base path is placed in the Domino data directory as follows:
Example on Microsoft® Windows®:

C:\LOTUS\DOMINO\DATA\DAOS

Example on Linux® (SLES 10) or IBM® i:

/local/notesdata/DAOS

If you want the directory elsewhere on the server, enter a full path, for example, on Windows:

C:\DAOS

If the directory you specify does not exist, Domino creates it for you.
Note Make sure that the Domino administrative user has file-access permissions in the directory appropriate to the server's operating system.

Defer object deletion for n days Use this setting to keep objects in DAOS from being deleted for an additional number of days after the last reference to them from any document is deleted.
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.

7. 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.

8. To put the new configuration into effect, restart the server.
