Incremental Statistics Gathering?
Sep 12, 2012 am having Oracle 9i RAC on IBM AIX .
I have large partitioned tables ( 4 partitions are added every month ). Is is possible to collect Incremental Statistics Gathering on these objects ( 9i ). If I collect stats with Ggranularity => ALL and ESTIMATE_PERCENT =100 the stats are accurate but it takes so much time .
One way may be to collect stats as Ggranularity => PARTITION for each new partition ( this quite fast ). but what about the Global Table Stats?
Online Gathering Statistics For A Schema
Dec 24, 2012Is it possible to gather stats for a schema which its in use. When i try to analyze the tables of a schema it shows that the statistics for that table is locked. So is it possible that instead of analyzing a table one by one , can i go for gathering the Schema stats while the objects of that Schema is still in use ( like DML or select statements being issued on those schema objects) .
DB version : 10.2.0.4
OS version : RHEL 5.8
DB type : RAC
Gathering Statistics With Cascade Option Is Slow
Oct 9, 2012The database is 11.2.0.3 on a linux machine. I issued the following command, but the session was a little slow. The table size is about 50 GB and has 3 indexes. I specified "degree=8" for parallel processing.
When gathering statistics on the table , parallel slaves were invoked and gathering statistics on the table has finished fast enough. However, when it goes to gathering statistics on the indexes, only one active session was invoked, and thus "degree=8" option was ignored.
My question is :
Do I need to use dbms_stats.gahter_index_stats instead of "cascade" option in order to gather statistic on the indexes with parallelism?
exec dbms_stats.gather_table_stats(ownname=>'SDPSTGOUT',tabname=>'OUT_SDP_CONTACT_HIS',estimate_percent=>10, degree=>8 , method_opt=>'FOR ALL COLUMNS SIZE 1',Granularity=>'ALL',cascade=>TRUE)

View 2 Replies View RelatedServer 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.

Server 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.
Database Versus System Statistics
Aug 26, 2011In the article regarding gathering CBO Statistics, it states: QUOTE When an Oracle database is created, a job will be scheduled that will generate the database statistics for you. You will still need to collect system statistics however, as these are not collected by the automatic statistics gathering mechanism.
what is the difference between "database statistics" and "system statistics"? In other words, do I need to run this script for each schema owner in my 10g/11g instance?
variable whoami varchar2(20);
begin
select user into :whoami from dual;
end;
exec dbms_stats.gather_schema_stats( -
ownname => :whoami, -
options => 'GATHER AUTO', -
estimate_percent => 15, -
cascade => true).
