Server Administration :: When To Gather Table Statistics
Apr 21, 2012Why do we gather table statistics manually ?Is it because of database performance.
I know In Oracle Database 10g, Automatic Optimizer Statistics Collection reduces the likelihood of poorly performing SQL statements due to stale or invalid statistics and enhances SQL execution performance by providing optimal input to the query optimizer.
Optimizer gathers statistics when 10% table rows have been changed.

View 3 Replies View RelatedServer Administration :: Impact Of Up-to-date Statistics On Main Schema Objects
Feb 29, 2012I am looking at a performance issue at the moment and trying to replicate on a test system. I am initially looking at the impact of upto-date statistics on the main schema's objects.
For this I wanted to:
first run the batch with whatever stats were present in the database Flashback the db to before the batch . Gather stats Re-run the batch with updated stats and compare results.
However, I inadvertently ran the stats job before running the load the first time! I have the SCN from when the environment was set up like production (ie before the stats were run) so am I correct in saying that if I flashback to this point then the stats will be "old" and I can just run the batch then? I know I can verify this when I Flashback the database by looking at LAST_ANALYZED on tables etc but it would be good to know this before hand as it's a 12 hour batch.

Server Administration :: Privileges Required For Export
Dec 1, 2011I have one question regarding privileges required for export.I read in a document that
Quote:
If you do not have the system privileges contained in the EXP_FULL_DATABASE role, you cannot export objects contained in another user's schema. For example, you cannot export a table in another user's schema, even if you created a synonym for it.
what are the system privileges required in EXP_FULL_DATABASE role to perform export objects contained in another users schema?
