Re: SQL created table slows reporting tool -- MIDRANGE-L

There is no real difference from a change management perspective from
creating an index "willy-nilly" and creating a logical "willy-nilly".

Unless your CMS handles DDS logicals but not SQL indexes.

Interesting fact about indexes/logicals....the system will use them to
regardless of where they are at or what the authority to them is. When I
worked at a larger shop, I often created indexes in a work library to see
if they would be of any help before jumping through the hoops required to
move an object into the actual production library from development.

the datawarehouse currently is on the I. This is sort of a pilot project.
But the table he created is 3.5 mill records and caused the crystal
to stop out of memory.Not going to do anything will nilly. I would be more
comfortable to create a logical. trying to learn some of the newer features
on the I which are available to us.

To the OP - as I suggested elsewhere, be VERRRRRY careful!

Using Run SQL Scripts from Navigator is a verrrrrrry unmanaged process.

I have never used System I Navigator to create an index.

I do know Navigator can create the SQL statement to create
an index or even a table from an existing index or table,
but I have never created an SQL statement from Index Advisor,
but I do see a way to do that:

Expand Databases, then expand Schemas, then select and expand
a Schema/Database(Library), then right-click a Schema and
click on Index Advisor in the far-right menu to open the Index
Advisor window.

In the list of Tables at the left of the Index Advisor window, you
can right-click to get a window that has >Create Index< as an option.

I expect it will take a minute or two to create sql for the index
and open Run Sql Scripts.

Happy Holidays.

As time permits you may want to look at System i Navigator Index
advisor.

Index advisor provides recommended indexes you can build to improve
response time.

i beleive they have an option 'group on server' at any rate we have
been much better since we switched to Views on the i rather than the
ad hoc crystal sql. The issue here is we have a new data warehouse
file which is very large and has no indexing.

Actually I'm not saying that you have to make either a stored proc
or LFs or views.

You do need to be sure that you tell Crystal to run the query on the
server, not at the PC. Crystal at least used to, by default, run all
queries on the PC, which means that the entire table had to be
downloaded from the server, then the query is run against that "full"

copy.

I like the idea of using a view - to limit the columns downloaded -
and maybe the rows, due to selection. You will still benefit from
making the query be run on the server, then downloading only the
results. I think this is especially the case, because you will
likely not want to make a view for each WHERE possibility - so if
your Crystal report has parameters for selection, again, you need to
run the query on the server
- it's a setting somewhere in Crystal, last I saw, which is years

ago!

in this case i was just taking a peek at the raw table. So it
seems that what you are saying is we have to make either stored

logical/views

on the Ibm i. this is fine, This is what we currently do on the
dds based PF's.

Is the out-of-memory condition on the PC or on the IBM i?

In any case, be sure to set CR to have the SELECT done on the
server, that is, on the IBM i - NOT on the PC - in the latter
case, the entire file has to be downloaded, THEN the query is run
against it. Bad Bad

Bad!!

There are other confusing things about this question, but I'll
leave my questions to what I asked already.
