Kesh - What do you define as performance?
1. How fast a table is analyzed?
2. The performance of the queries that use the statistics that were
collected?
What Oracle version are you on?
In theory, you can analyze tables when the system load isn't so great. In 9i
you can even have Oracle decide when a table needs re-analyzed so it really
lowers the system requirements.

Hi all,
Can anyone tell me which of the following performs better in
collecting statistics of a table:
Analyze command or
Dbms_stats.gather_table_stats
I tried my queries with both the options -- but always Analyze is
out-performing the dbms_stats.
But i read in a document that Dbms_stats performs better !!
Besides I also read that Analyze command will be deprecated from Oracle 9i.
So can anyone tell me why dbms_stats is performing poor...
Are there any paramters that need to be set to increase the performace of
dbms_stats ?
Thanks in advance.
Regards
Kesh
