T5B0169 testing. Rollforward results.

[ca.portal.admin]

I found the results quite interesting. Page requests were down about
52.5K, reads down, writes down, calc on target just a tad better, via on
target 2.5K better, less fragments stored, index activity just a wee bit
behind the only down side.

Day 2 saw similar results in most categories but did store 10 more
fragments in the fix loaded image, still staying ahead in fragmentation.
Again about 50K less page requests. Day 3 page requests were down 80K,
fragments down again. Day 4 I saw writes up 2K for the first time in
the fix-loaded image, but again page requests were down, the time about
76K. Day 5 was a light weekend day with little differences, 26K less
page requests in the fix-loaded image. Day 6 a large batch purge job
was run and the results are quite interesting.

I pulled all the index stats because they were identical, but I'd say
4.3 Million less page requests says it all. 200K+ less reads and writes
also. I guess this fix may be a keeper. Day 7 was the last day rolled
on both images. Again I'm seeing 80K less page requests and better via
on target, with other differences relatively insignificant.

SQL question
"Hi everyone,

I have a SQL question from a developper that I can't answer. He wants
to get all B records from a set A-B, but only the B that are not an
active member of the set A-B. He tried with NOT A-B, and it doesn't
work. Is there a way to do this in SQL?

Thanks,
Laura Rochon

Re: SQL question
"Consider you have an owner (REC-A calc) and member (REC-B via SET-A-B)
and you want some columns from both. Something like this will get the
owner and all the members. SET-A-B is essentially the foreign key.

SELECT A.col1, A.col2, B.col1, B.col2, B.col3
FROM sqlschem.""REC-A"" A, sqlschem.""REC-B""
WHERE A.calckey =3D calckeyvalue
AND ""SET-A-B""

If you want REC-A data when SET-A-B is empty do this.

SELECT A.col1, A.col2, B.col1, B.col2, B.col3
FROM sqlschem.""REC-A"" A, sqlschem.""REC-B""
WHERE A.calckey =3D calckeyvalue
AND ""SET-A-B""
PRESERVE A

I hope I didn't misunderstand the original question.
