Re: Index Advisor

I see in the latest TR there is a RESET_TABLE_INDEX_STATISTICS procedure;
maybe that is worth a look.

Cool - I kind of thought I remembered seeing something.

So probably the OP doesn't have to do anything with the table he's looking
at.

Vern, I think that's already there. On a periodic basis we simply clear
the advised indexes. Then let the new ones populate.

If we embark on a project to build several indexes then we clear the
advised indexes again and look to see what's being advised after the work
we did.

Hey Gord

How about entering and RFE for IBM to provide tooling to manage older
recommended indexes? Or is there already something like that?

I have recommendations for indexes in libraries that no longer exist.
Working with the schemas is ACS is cumbersome since it doesn't allow
selecting or positioning when in the index advisor. Each time a
recommendation is deleted the display is refreshed thus losing the
positioning. I find the web navigator slow as well.

This file is flagged as all yes (as shown above). I've seen some which
were not, such as SYSTABLES, and temporal table log files.

This doesn't address your concern about "admonitions".

Are there any restrictions, prohibitions, admonitions on updating
QSYS2.SYSIXADV in SQL or a program?
