Subject: RE: Analyze table and locking
Analyze index validate structure takes shared lock on the table disallowing any changes to the table or indexes. That's the only way to validate the structures.
In earlier versions (7.3 ?) 'analyze ..compute' used to take table level locks. From 8 onwards, compute or estimate does not take any table level or row level locks at all...
Thanks

Subject: RE: Analyze table and locking
Ok, now I'm confused................
One reply
---------
It depends. For instance, 'analyze index validate structure' takes out
'shared' lock on the table (preventing inserts/deletes/updates), while
'analyze index compute/estimate statistics' does not.
Another
-------
Compute option locks a table, but 'estimate' doesn't
Anyone have a definitive answer.
PS. Thanks to the guys who have replied up to now.
