Well I know what journal scraping is, I just was't aware of how you might
be using it.

I also know how partitioning works, so that's not a mystery to me either.

I am still struggling to see how DB2 Multisystem partitioning would help
you with your journaling receiver issue unless you are scraping data from
journals and transforming it into some kind of home-brew table partition.

But I figure there are probably some details being lost in translation.

Perhaps you've never heard the term "journal scraping" before. Basically
this means you scrape data from the journal into database files. Sort of
like transaction history files.

When you do partitioning you can do things like
CREATE TABLE FOO
(A DATE)
PARTITION BY RANGE(A)
(STARTING('2001-01-01') ENDING('2010-01-01') EVERY(3 MONTHS))
This is straight from Knowledgecenter.

Each partition is in a separate 'member'.

Hey Rob,

Well technically, I guess you mean your receivers or receiver libraries
are
huge.. ;)
But wouldn't that primarily be a function of how many you retain ?

And what advantage or implication is there for journaling that DB2
Multisystem brings to the table?

Larry,

IBM is giving more and more examples of using partitioned tables. Even
for locally stored data. So, we may not yet "have" to do it; we "want"
to
do it. We may not yet be in the area of the partition (aka member) is
too
big and we "have" to have partitioning. However we do some serious
journal scraping. Our journals are jaw dropping huge compared to our
data
libraries.

PRTDSKINF *LIB
% of Size in
Library Owner Disk 1000 bytes
#MXJRN MIMIXOWN 41.24 2260022186.0
ERPLXF SSA 8.00 438505435.1
...

So if I want to partition pricing history (for example) by month and
year
that's my business.

One addition I'd asked for was DB2 Multisystem (5770-ss1 option 27).
Simply because I'd like to be able to have locally partitioned tables;
particularly for historical data.

$25,000

Are you kidding me IBM? One LICPGM cost more than the rest of the OS?

That's just nuts.

Mainly just venting, as I don't expect this post do solve anything.
