Yes, that's bad. You have analyzed the data dictionary tables. You need to delete the statistics for them.
-----Original Message----- Sent: Thursday, May 09, 2002 3:04 PM To: Multiple recipients of list ORACLE-L I have recently changed the analyze script. Earliar it was dbms_utility.analyze_schema(...) statement, It is now changed to dbms_stats.gather_database_stats(); Is this a problem? The response time for select count(*) from dba_extents is also 30 minutes. It is not specific to any table. Thanks, -- Babu -----Original Message----- [mailto:[EMAIL PROTECTED]] Sent: Thursday, May 09, 2002 11:36 AM To: Multiple recipients of list ORACLE-L that's interesting... since the data dictionary is NOT analyzed, setting optimizer_mode=choose would force the query against dba_extents to RULE which it what it is supposed to be doing anyway, Hm. The question now is, what is the optimizer_mode set to when the problem happens? Did any of the data dictionary tables get accidentally analyzed? And -- how many extents are in use in the database? Could it just be a symptom of missized tables and indexes so that the number of extents is way high? Although Oracle is *supposed* to allow unlimited extents, in practice anything higher than 4096 extents in an object (at least in 8i) tends to slow things down. |--------+-----------------------> | | | | | | | | jack_silvey@y| | | ahoo.com | | | | | | 05/09/2002 | | | 02:18 PM | | | Please | | | respond to | | | ORACLE-L | | | | |--------+-----------------------> >----------------------------------------------------| | | | To: [EMAIL PROTECTED] | | cc: (bcc: Rachel Carmichael) | | Subject: Re: DBA_EXTENTS problem | >----------------------------------------------------| Babu, We had a similiar problem, and setting optimizer_mode = choose in our session solved it. Something to do with optimizer and DD access. Give that a try. I had the same problem with DBA_INDEXES and that fixed it. hth, Jack --- Janardhana Babu Donga <[EMAIL PROTECTED]> wrote: > Dear List, > > When I query dba_extents , Iam getting response > after half an hour to 40 > minutes, but when I query any other dictionary view > it is spontaneous. > Everything else is fine in the database and there > are no problems, except > the above problem.
