RE: Q about Oracle Optimizer
Hi all, Although it is a little late in this thread, keep in mind that 'STATISTICS=ESTIMATE' kicks in by default for export. This could also have affected the final outcome, i.e. CHOOSE with incorrect stats isn't exactly the right combination for the best performance ;-) IMHO, this gotcha has caught out a lot of DBAs - even experienced ones...

RE: Q about Oracle Optimizer
John, Thanks for update. But in our case no export was involved in migration as it was not our option for migration because of Database size. We used 7.3.4.5 datafiles and migrated...there were no statistics of our objects Regards MOHAMMAD RAFIQ Reply-To: [EMAIL PROTECTED] To: Multiple recipients of list ORACLE-L [EMAIL PROTECTED] Date: Tue, 21 Aug 2001 16:50:46 -0800 Hi all, Although it is a little late in this thread, keep in mind that 'STATISTICS=ESTIMATE' kicks in by default for export.

RE: Q about Oracle Optimizer
If the objects in a query have not been analyze, then rule mode is defaulted. If there are objects in the database which are analyze, yet the tables you are using are not analyzed, rule mode will still be used. If one table is analyzed, and it is joined with 5 others which are not analyzed, then cost base will be used. There are a few parameters that need tweaking when you first go from rule to cost base. Do not criticize someone until you walked a mile in their shoes, that way when you criticize them, you are a mile a way and have their shoes. Christopher R.
