Chris,

I remember either talking with an IBMer or reading that with putting journal
receivers into a separate ASP for 'performance' reasons is not really needed
today. Today's disks and controllers are much faster and handle the extra
I/O much better than thier grandkids...

Now there are other reasons for doing it around data recovery. I always have
to add that if yo are using additional ASPs for data recovery, make sure
they are in different raid sets from the System ASP and as well as ASPs they
are protecting.

I like to keep the journal in the same library as the objects, but now
with Mimix, we have multiple libraries being journaled with one journal
so that practice broke. The journal receivers are in a different
library. We only have one ASP but if I ever get enough disk arms to
create a second ASP, I will move the journal receiver library to the new
ASP.

Nightly we detach the current journal receivers and then backup the
receiver library. This allows us to delete the detached and saved
journal receivers. (Running at 87% storage utilization. But alas we
have a new system in house with almost 3x the storage space.)

Would be nice if IBM put some "best practices" at
http://publib.boulder.ibm.com/infocenter/iseries/v7r1m0/topic/rzaki/rzak
ijrnrcvlib.htm

If you have multiple disk pools (I don't) then this may apply "the
journal
and the journaled objects must be in the same disk pool".

The one sample they gave at Infocenter had their journals and receivers
in
a library beginning with a dollar sign.
