Saira, you can turn on tracing, you can analyze tables, create histograms
and create indexes.
The first thing to do would be to take 10046 trace, level 12 and analyze it
with tkprof. Then,
you should find the few most expensive SQL statements and see whether
something quick and easy
could be done, like index creation, for instance. If not, and the
performance isn't satisfactory,
then determine where is the problem and contact the vendor. No big science
there and nothing more
you can do.
