Schema analyze takes lot of time

edited Jun 16, 2011 7:06AM in Database Administration (MOSC) 8 commentsAnswered
 Hi,

We use Oracle 9i on Windows 2003 server. Our schema analyze is taking long time to complete ( more than 5 hours to complete 40% estimate for schema and 4 hours for another schema).

We use following command to take statistics:

exec dbms_stats.gather_schema_stats(SCHEMA_NAME,40,cascade=>TRUE);

Please let me know how can we reduce the time? Do you suggest to take stats daily basis? We have several tables which are modified daily.

Howdy, Stranger!
