What are the stages of optimization in DDO?

One of the great features of DDO is how it works through its optimization stages automatically to ensure you get the best 'bang for buck' from your Domino server.

The first stage is ensuring database properties on databases inheriting design from the mail template (or other identified templates) are set correctly. Any databases out of line are quickly put back into line.

Stage two optimization ensures databases that need to have DAOS applied, have it. Any new databases created based on the identified template names, get DAOSified. That night a specially targeted DBMT session is run to make it happen.

Stage three optimization is NSF file defragmentation. This occurs when and if required.

Other stages of optimization are core to the product, they include:
  • only running DBMT on databases with active freespace, no more compacting for the sake of compacting.
  • only running DBMT on databases that haven't had maintenance run for a given period.
  • running DBMT index optimisation on all databases.
  • running maintenance on system databases periodically
DDO can also automatically schedule DAOS synchronization, shutdown the mail router before performing maintenance on the mail journal and will do a full NTFS freespace optimization when required.

All this happens in a single package. If you would like to give it a go, check out our website at
