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.
