I believe at one time that was true. Since then the CQE has been
displaced by the SQE.
I would be looking at those logical files since they are most likely older
to see the page size (as some have suggested) and other attributes. Might
be worthy of a rebuild with newer parameters.

That has never been the case.
And now-a-days, pretty much everything goes through the SQE.
Originally, if you referenced a LF on an SQL statement, you forced the

Perhaps that's what you're thinking of. But again, even that is no

I've been using Index Advisor and Run Sql Scripts "Run and Explain" to
analyze some of our queries. I'm looking for increased performance.
I have a large file/table OEBOXCBX with a logical files defined with the
following keys:
LF #1: BXCOM#, BXORD#, BXREL#, BXBOX#, BXPRT#
LF #2: BXCOM#, BXORD#, BXREL#, BXBXNO, BXPRT#
I ran an SQL statement over a complex SQL view that contains this file.
RSS Run and Explain recommended the following index:
CREATE INDEX ASTHHOBJ/OEBOXCBX_IDX
ON ASTHHOBJ/OEBOXCBX (BXCOM# ASC, BXORD# ASC, BXREL# ASC) UNIT ANY
KEEP IN MEMORY NO;
My question is why the SQE wouldn't use one of the existing logical
