Re: SSD Best practices

Hi Luis -

Please remember that DB2 has the concept of "Index Only Access", so if your
query requires only the columns defined in a particular index there is no
need to access data from the physical file. In this case, I can see why
having an index on the SSD could be a good thing, even if the corresponding
table remains in a "standard" DASD.

I assume that's only applicable to SQL and not RLA, so it would be of
limited benefit to us. Also, I don't think that any of the SQL
programs that I've personally worked with were limited to fields
appearing in any index (or combination of indexes for that matter).
