Re: Transaction logging. -- DOMINO400

Clients and non-daosified servers function as they would currently. If it's
pulling down an email to a local replica (or non-daosified server replica),
the attachments are all stored in the NSF. This is how it works... :)

If I make a local replica of a DAOS enabled database are the attachments
back in the replica database, or in a bunch of little files on the local
replica? Probably back in the database. Otherwise that would definitely
not be a server issue then, eh?

So instead of the client accessing the document and finding a funny link
that it has to interpret as a link to the DAOS file the server passes back
the actual attachment?

Can we find some sort of official document that gives us good news? Would
that forum qualify as "official"?

They are wrong about that. In a quick search of the Domino 8.5 forum at
devWorks, I found 2 IBMers who also said that DAOS is just server-only and
that clients don't need to be upgraded.

Now that's not what they told us. "Domino 6 and 7 clients will not

8.x
Last bullet on slide: "Domino 6 and 7 clients will not recognize DAOS."

I could pick some poor dumb SOB and convert their archive to use DAOS

and

see if they can still get to their attachments.
Back up plan would be they'd better quickly take the mandatory on line
training so they can get permission to upgrade their client to 8.5.

Clients don't have to be upgraded. It's transparent to them.

Really looking forward to DAOS. Have to get all those clients

upgraded

first.

You don't need to do anything different as long as your disk drives

aren't

already experiencing usage/utilization problems. IIRC, Walter said

you'll

see about a 3% hit by starting transaction logging, but you'll

probably

recoup that once you setup DAOS and see the reduced I/O overhead that

it

will likely bring.

Went to an IBM & Partner intro to 8.5 last week. One of the new

options

we may look at requires transaction logging be fired up. Most of

the

time

when I hear about transaction logging it makes me think of something
primarily run in a lab or on a test machine. Because, they mention
keeping your data on one drive and your transaction logs on another

drive.

Well, my machine has ninety disk drives. All Raid 5 protected.

Does

it

really make sense to put the transaction log on dedicated disk? On

the

i

that would involve Auxiliary Storage Pools or ASPs. In theory I

could

have two ASPs: Main data in one and transaction logging in the

other.

I

can't imagine it would take more than a few 70gb disks to do

transaction

logging.
Raid sets smaller than 4 drives are known to have serious

performance

implications. Technically you can do a 3 drive raid set, but unless

the

customer is just migrating from a S/36 they will notice the

performance

hit versus a 4 drive (or more) set.

Is this separate disk stuff recommended on a "real" os?
Do I need a full RAID set in an ASP?
