Maximize the disk space savings provided by Domino Attachment and Object Service (DAOS) and ensure that your environment is properly configured for best performance with this feature. This one-stop quick reference includes the best practices for upgrading your databases, configuring DAOS on the server, and performance tuning the DAOS repository, transaction logs, and mail.boxes. It also provides a troubleshooting checklist and instructions for sending a database that has objects stored in the DAOS repository to IBM Support.

Amidst all the documentation and blogging about the Domino Attachment and Object Service (DAOS) in IBM Lotus Domino 8.5, it’s easy to find descriptions of the disk space savings it provides and the performance improvements it brings to both Domino maintenance tasks and the backup/restore process. But you have to do quite a bit of searching and reading to find out how to implement it in your specific environment or tweak it for best results. To save you time and energy, I’ve assembled the essential information you need — including how to prepare your servers and databases for DAOS, best practices for performance, and troubleshooting techniques.
