Enabling DAOS on a database – new recommendation

Almost one year ago, I wrote about “How To Wast Space” when enabling DAOS on an application. And I assumed that it might not be sure that the compact task will always do the recompress BEFORE the attachments are moved to the DAOS repository.

The recommended way to enable DAOS on an application and recompress attachments was:

  1. load compact  mail\example.nsf  -c -ZU -DAOS ON

According to IBM technote #1411563, the new recommendation is to perform 2 compacts.

First, enable compression and then enable DAOS.  This is critical for customers which have upgraded from 6.5x to 8.5

  1. load compact  mail\example.nsf -c -ZU
  2. load compact  mail\example.nsf -c -DAOS ON

If you want to get the most out of DAOS, this is the way to do it.

btw. the IBM technote obviously has a typo. See the mistake?
