You could build the archive on ADAM, and enable the indexes to allow for efficient medial substring indexes. :)

Basically, yes. Though I would point out, this is hardly reusing DNTs...this is more starting over. :) For the sake of clarity I would point out that such a re-promotion would need to be over the wire and not IFM. IFM just picks up where the last left off, as you are using the old database again, and so the same AD level rules apply. ~Eric -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Ulf B.

Technically not needed by the database layer, and not needed by the application, but needed to keep the data together for the application. So if you look at AD from the outside it won't be referenced, if you look at ESE it's just a DB and doesn't care about the data stored within, but you still need it in between to store the AD in the ESE. Right? >* DNTs are not reusable Unique per Server and don't provide any reference across servers. If AD looks for a parent object by looking up it's known DNT (stored with the child), ESE would fail in that moment, AD would not able to go to another server and look up the same DNT in it's database. The AD is distributed, the ESE is local, and DNTs are part of the local table. If I understand correctly: DNTs are reusable in ESE, however ADs implementation does not allow DNTs to be released / reused on a single server, and the database will only "reuse" them if you recreate the DB by repromoting (cause the data is replicated from other servers into a virgin ESE, and DNTs are assigned from the beginning at this point).
