With the expanding use of graphics within the body of e-mail messages and the growth of high resolution graphics in signature files, a large volume of storage is being consumed. While DAOS is effective in removing the attachments from an e-mail, document body compression is designed to reduce the overall storage requirements by compressing elements within the body of the message. The process of compressing non-summary information within the body of a message has been shown to reduce the overall mail database requirements by up to 60%. This compression feature requires that databases be at a minimum of ODS 48. Later versions of the ODS such as 51, which is provided in version 8.5 can also be leveraged. Please refer to the Domino 8.5, Administration Help for more current information on how to update the ODS version on databases.

In addition to upgrading the servers to 8.0.1 (at a minimum) and the ODS (ODS 48 at a minimum), the databases will need to be enabled for future documents and older documents already present in the databases.

To enable compression on future documents, the Advanced Database Properties... | Compress document data needs to be checked. The process can be done on an individual database (or a group of databases) through the Administration Client by going to the Files view; select the files and click on Advanced Properties... on the sidebar.

There are a number of different options that are available on the Advanced Database Properties... tab; the selections on your databases may be different than what is presented in the following example. Locate Compress document data and select the option. Click OK to apply the settings for the selected databases.

The next step is to go back and compress the data that already exists within the databases. From the Administration clients' server console, execute the command load compact -c -v.

The databases will participate in document body compression until the administration team uncompresses the data. To uncompress the data within the databases that have been compressed, from the Administration clients' server console, execute the command load compact -c -V.
