RE: Analyzing indexesNo but validate structure populates the index_stats view which is the only way I know of to get the index height, leaf rows, deleted leaf rows, and pct. of used space which is what I normally use in determining if an index needs to be rebuilt or not. Is there another way?
----- Original Message ----- To: Multiple recipients of list ORACLE-L Sent: Tuesday, March 11, 2003 10:49 AM Chuck, Do you think these indexes are corrupt? Validate structure doesn't give you statistics like Compute Statistics or Estimate Statistics does. Jerry Whittle ASIFICS DBA NCI Information Systems Inc. [EMAIL PROTECTED] 618-622-4145 -----Original Message----- I need to determine whether or not a couple of indexes need to be rebuilt. The problem is the indexes are quite large and on a 24x7 high volume database. If I try to run an "analyze validate structure" to gather the data I need to make that decision, it sets a lock on the table for about an hour which I can't afford to do. There is no slow time when I can do this and management has said before they're not going to spring for the partitioning option to break the indexes up into managable pieces. Is there some other way I can get the information needed to determine if an index needs to be rebuilt or not without setting a lock on the table?
