Order By clause in an SQL doesn't have an exiting access path it can use
so QZDASOINIT job has to build one on the fly.

Subject: Access path / index rebuilds


Hopefully someone can answer this for me in easy terms.

Why would a system rebuild access paths for files when being used by
many ODBC (QZDASOINIT) jobs?  For example, the jobs will sometimes go in
to an IDX-xxxxxxx where xxxxxxx = the name of a file.  The online help
shows that the IDX status means it's rebuilding the index (access path)
to whichever file it's listing.

What prompts the rebuild?  Is there somewhere we could go look to see
why it's doing that?  Additionally, in Performance Navigator there's a
chart for Index Rebuilds/second - the online help for describing why is
pretty vague there also.

Please advise - thanks in advance for your help and for not biting my
head off if this is basic and I just never learned it - hah!
