DAOS (the Domino Attachment and Object Service) is just so easy and such a no-brainer idea that they are enthused enough to do it.
The all-important additional disk configuration for the Logs and DAOS data, the server restart, the console reporting that everything is working .... and ....
An empty DAOS disk and folder!
While the customer is wondering when the additional petabytes of space are going to be released, don't forget, that once DAOS is enabled on the server, one must still run a copy-style compact to retrospectively gain DAOS savings from existing applications (AHEM! Databases!) and the attachments stored therein.
- Ensure Create_R85_Databases=1 has been set with the "set config Create_R85_Databases=1" command on the Domino Server console (either direct, or through the Admin client),
- Run a copy-style compact to apply the new ODS to the existing databases "Load compact -C",
- Assign additional disk drives to the system either on the SAN, virtually, whatever... (1 for OS, 1 for swap, 1 for Data, 1 for Logs, 1 for DAOS .... "1 disk to rule them all" IS NOT a good idea here, but RAID IS!),
- Enable Transaction Logging (restart Server),
- Enable DAOS (restart Server),
- Enable Activity Logging (not essential but HIGHLY recommended),
- Highlight every database deemed suitable (and even some that aren't) and "Right-Click" -> "Advanced Properties" -> "Enable DAOS",
- Do ANOTHER copy-style compact with DAOS enabled and configured to extract the attachments retrospectively and reduce storage space by consolidating the duplicates (YES, you WILL be surprised how much space you will recover!)
- NOW you can smile at the customer as the free-space on their server just keeps increasing!
I love DAOS. And so do customers who discover the oodles of disk space they never knew they had :-)
