We currently have an application we are trying to speed up. In
researching rule/cost based optimizers, I read that the cost based
optimizer was the way to go (although rule had its moments) because that
is where Oracle would be focusing any
FWIW, set_ev has produced over 2,000 trace
files on Oracle8i that Ive seen Using DBMS_SUPPORT is probably a
better idea anyway, though. Note, however, that the procedures in DBMS_SUPPORT
just make calls to SET_EV.

Mladen's advice actually covers that. No matter what's causing the slow
performance, if something's taking time, then it will show up in the
10046 trace data. That's why we love her so.

Title: 8.1.7 + redhat AS 2.1 = trouble
Are there know binutils or other issues when installing
8.1.7 on redhat AS 2.1?
Attempts to run genclntsh keep
getting undefined references in libc.so.6?
I can't find anything on Metalink or google about
running AS 2.1 and 8.1.7 together.
