That's correct. If you don't want to see the old advisories anymore,
delete them. The system will start building new ones.
Now there is value in having a good sample because the system will tell you
things like how often an index is called for, and several other important
items (materialized query comes to mind) that will change over time and
provide good feedback. I like to see about 90 days or more in there before
I start messing around too much. And then I need a practiced eye for the
application too, so that's where a good user expert can help.

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
vhamberg@xxxxxxxxxxxxxxxwe 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 doesn't address your concern about "admonitions".

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