I am starting to generate statistics on an 8.1.7.4 database and I have a
few questions.
- Should I be using the dbms_stats package or the analyze command for
this version of Oracle?
- Looking at some of the threads in the archives, I note that people do
not generally recommend histograms. If I use
dbms_stats.gather_schema_stats, how do I set the method_opt parameter so
that I do not generate histograms?
- What is a good starting point for "estimate_percent"? This is a 70gb
databsae used for a data warehouse application. Data is added from the
production database every hour and we have a growth rate of about 20%
per year.
Thanks,
Peter Schauss
