Re: Navigator - Index Advisor for Existing Indexes

I am in no way, shape, or form an expert on this. I have been seeing the
same thing on my system for years now.

That being said, I would guess there is something "wrong" with the existing
index. There is an "Index Type Advised" column. Most of those advised for
our system is "Binary Radix". Occasionally I see "Encoded vector (not
unique)". One of the most advised indexes on our system is over a
particular packed field in the item master. I've had an index based on that
field for years, yet it keeps advising it.

There's also a column headed "NLSS Table Advised" column which is almost
always either "*HEX" or "QLA10025S".

I don't know if either of the above have anything to do with it, but since
we have no performance issues of any kind, I'm not too excited about it.

Hi All,

Can someone please explain to me why the Index Advisor in Navigator will
ask for an index even though it already exists? I ran the index advisor
against my data library and it asks me to create an index for a table. When
I try to create the index, the system reports an error telling me the index
already exists. However, the "Times Advised for Query Use" for this index
keeps going up.

Any ideas?

Thanks!
