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 files as an index? As an RPG guy, this makes no sense to me.
TIA,
Greg
