Rick,

Thanks for prompt reply.
I tried it (deleting statistics before analyzing table) and it worked.

Any ideas, whether cost-based optimizer need statistics on IOT or having statistics on PK index of IOT would be enough?

According to MetaLink you need to delete statistics and re-analyze I do not know your database version but this is supposely fixed in 8.1.6

execute

dbms_stats.delete_table_stats('<owner>','IPN_MEASUREMENT');

analyze table ipn_measurement estimate statistics ;

Ok, since my original message still hasn't arrived (sent couple hours ago), here it goes again (sorry, if you get duplicate).

First, sorry for asking this list before searching Metalink, but I don't have access to it right now.
So, here it is:

I'm getting:

ORA-00600: internal error code, arguments: [15163], [333], [17424], [16191], [], [], [], []

when analyzing one of the index-organized tables: "ANALYZE TABLE ipn_measurement ESTIMATE STATISTICS".

Now, similar statement analyzing other IOTs works fine.

Also, on the same table (ipn_measurement) analyze worked fine yesterday, and the table didn't grew too much since yesterday.

Any ideas?

Another question, do I really have to run "analyze table" on IOT for cost-based optimizer, or analyzing index would be enough:

"ANALYZE INDEX pk_ipn_measurement ESTIMATE STATISTICS"

because "analyze index" still runs with no errors.

Oracle version is 8.1.5.
