Hi,

I have a .. uhmmm... let's call it a bit of a weird question.

Okay here's the case:
We have a large public website running using Spectra 1.5.1 using a Oracle 8.1.7 
Enterprise database (runnin on a largescaled AIX environment). The spectra site runs 
on a highend compaq dlt380, 1 GB of ram.

The problem:
>From the dba's who maintain the database environment i've received the following 
>information. They are saying the following: "We see a very high non-index lookup 
>ratio in the application (they are talking about the codb). Could you please have a 
>look at it."

Then they have also supplied some statistics. They measured the performance during a 
two hour time span.

   consistent gets =   7440165
   db block gets =      5195
   physical reads =     93272
   logical reads =   7445360
   hit ratio =        98  
   table scans long  =       697
   table scans short =        97
   non-index lookup  ratio =        87 

My guess would be... some bad use of indexes in the codb db's design. But what i can't 
do is just go in there and make some changes and so... because i am not sure about the 
things that can go wrong. So my question would be if somebody out there experienced 
the same problem... and how did they go about handling this.

Kind regards.

Mathijs
