Collect statistics in oracle 11 g
Hi all
OPERATING SYSTEM: AIX
DB: 11G
I am trying to collect statistics for a specific schema using the mentioned below command:
> exec dbms_stats.gather_schema_stats ('schema_name');
The schema of such size is 140 GB, and it's almost an hour that the above command is still running.
I need to know if it is normal, is there a way to set the control above to the acceleration of reunification.
And how can we check if the above command runs successfully from the background, I mean if there is anyway or something like that?
Kind regards
Sphinx
Hello
The runtime for a 140 GB schema seems quite OK.
Without any other parameters, the work of gather_stats will use the 'compute' option, which takes a long calculation for each table.
I've written a procedure that checks for 'fade' in dba_tab_statistics tables and calculates these statistics only.
The request for these tables up looks like:
SELECT table_name, 'NONE' AS nom_partition
OF dba_tab_statistics one
Owner WHERE = i_schema
AND NVL (stale_stats, 'NULL') = 'YES '.
AND NVL (stattype_locked, 'NULL') = 'NULL '.
AND NOT EXISTS
(SELECT 1
FROM dba_tab_partitions b
WHERE table_owner = i_schema
AND a.table_name = b.table_name)
UNION ALL
SELECT table_name, nom_partition
OF dba_tab_statistics one
Owner WHERE = i_schema
AND NVL (stale_stats, 'NULL') = 'YES '.
AND NVL (stattype_locked, 'NULL') = 'NULL '.
AND nom_partition IS NOT NULL;
The preceding section is smooth tables, the lower part is flawed partitions for partitioned tables.
It allows the procedure to collect statistics for the tables and one or more partitions.
It ignores the tables that were calculated before the work of the default oracle.
See you soon,.

Collects statistics for tables using jobs in Oracle 11 G 11.2.0.1.0?
Hello
My query is regarding the collection of statistics for tables.
My Version of Oracle DB is:

NLSRTL Version 11.2.0.1.0 - Production
In versions of prior oracle db, we used to schedule tasks to run on a daily basis for collecting statistics. Especially for tables that are frequent and huge inserts.
I read that in 11g stats for all of the schema on a database are automatically make every night jobs. I checked these jobs and I see that they are running on a monthly basis [joined query]. This job is enabled and is scheduled to run monthly.
This means that my diagram will be analyzed on a monthly basis. My understanding is correct?
Can I still plan jobs to collect statistics for specific tables on every week? This will diminish the performance?
We expect 100000 documents to insert on a daily basis.

AUTHID CURRENT_USER collect statistics
Hi all
I use Oracle Database 11 g Enterprise Edition Release 11.2.0.3.0 - 64 bit Production. I created a procedure that collects statistics from table using DBMS_STATS using AUTHID CURRENT_USER to SChema1.
CREATE OR REPLACE PROCEDURE SCHEMA1.getstats ( p_schema IN VARCHAR2, p_table IN VARCHAR2) AUTHID CURRENT_USER AS BEGIN dbms_stats.gather_table_stats(ownname => p_schema, tabname => p_table, method_opt => 'FOR ALL COLUMNS SIZE AUTO', degree => 8, force => true, no_invalidate => false); END;
I'm trying to use the same procedure to collect statistics for a table in another schema. However, I get the error ORA-20000: impossible to analyze the TABLE ' ' SCHEMA2.» DETAIL_VALUE', insufficient privileges or does not exist
EXEC getstats ( 'SCHEMA2','DETAIL_VALUE');
I grant privileges on the table to SCHEMA1. But still get the error. I understand AUTHID CURRENT_USER will attempt to use as long as the procedure as own drawing, but still, I get the error. Can someone help me on this?
GRANT ALL ON DETAIL_VALUE TO SCHEMA1
It has nothing to do with authid user current and everything to do with the privileges. Grant on the table is not enough for you to analyze.

It is possible that you can never bring his stats again
and everything will probably continue to work as expected
read the guide to setting performance to understand why you need to collect statistics and when
https://docs.Oracle.com/CD/E11882_01/server.112/e41573/stats.htm#PFGRF94714

How to collect statistics for a partition?
Hi all
I create a table partition. I need to collect statistics for this partition only. Before I used to analyze it, but now I need to analyze using DBMS_STATS.
What is the best way to analyze the partition using DBMS_STATS?
How long will it take to complete?
How can I estimate the time of accomplishment for DBMS_STATS before starting?
Thank you
I create a table partition. I need to collect statistics for this partition only. Before I used to analyze it, but now I need to analyze using DBMS_STATS.
What is the best way to analyze the partition using DBMS_STATS?
Follow the documented instructions: INCREMENTIELLE TRUE and GRANULARITY on AUTO.
See the section "Partitioned objects statistics" the doc of performance tuning
http://docs.Oracle.com/CD/B28359_01/server.111/b28274/stats.htm#i42218
With partitioned tables, the new data is usually loaded into a new partition. As new partitions are added and loaded, statistical data must be collected on the new partition and statistics need to be updated. If the
INCREMENTALfor a partition table is set to the valueTRUE, and collect you statistics on the table with theGRANULARITYparameter defined onAUTO, Oracle will collect statistics on the new partition and update statistics on the overall table by scanning only those partitions which have been modified and not the entire table. If theINCREMENTALfor the partitioned table is set to the valueFALSE(the default), then a full table scan is used to maintain the global statistics. It is a highly resource intensive and time-consuming for large party.How long will it take to complete?
No way to know - using an estimate of 10% takes less time than with an estimated of 40%, which takes less time than using 100%.
How can I estimate the time of accomplishment for DBMS_STATS before starting?
By comparing the amount of data and the percentage of estimate for the data that you have in the other partitions and the time required to collect statistics on other partitions.,.

Thanks for the reply. Actully there was some statistics locked to other tables, so problem is solved after runing commands below.
Select distinct owner, table_name, stattype_locked
of dba_tab_statistics, where stattype_locked is not null;exec ('SYS') dbms_stats.unlock_schema_stats

There is no precise answer to your question and you will need to test the different settings until you are satisfied with the performance - definition of the parameters used to collect statistics of the schema [556466.1 ID] program
Try with "Estimate percent" between 10% and 40%

statspack and awr is to collect statistics, or simply to present
Hi all
If I have a db with statspack installed in 9i
I took a glance at 13:00 then took antother wink at 15:00
so now I can analyze the period between 13:00 and 15:00
My question is, if statspack is NOT installed, is the db should run FASTER, because nothing is the collection of statistics
the statistics are collected in any case or statspack is just a way to get this perspective
and what about the AWR in 10g?
I have red this link
http://download.Oracle.com/docs/CD/B10501_01/server.920/a96533/statspac.htm#32191
but it do not answer this point.
Thank you very muchSTATSPACK and AWR do not run continuously and collect statistics, so that they cause no impact on performance.
When you run the blink of an eye it just reads the current statistics of the system to the $ V and X tables $ and stores them in permanent tables. The V$ X$ tables are always up-to-date even if statspack is not installed.

Collect statistics or an index first?
I am wanting to know which is the most effective in this scenario using Oracle 10.2 g...
1. create a new table.
2 fill the table with 10 million documents.
then either...
3. analyze the table to help gather stats
4 create indexes
or...
3 create indexes
4. analyse the table using statistics, including the index
Logically, I think that one. However, if there is no cost associated with creating an index on a table that is not monitored AND you will need to gather stats again after an index created I could see how it would not be that.I believe that the Dan point is that the index will have to statistics, just as the table will have statistics. It is probably more logical to collecting statistics on both at the same time (using the CASCADE option in the GATHER_TABLE_STATS call) instead of collecting statistics on the table and the index separately. Since you're using 10.2, however, it is less of a concern because the create index automatically collects statistics on the index. This is used to not be the case.

collect statistics for the tablespace
Friends...
OS: Linux
DB: 11 GR 2
Data size: 1 TB
I spend monthly multiple partitioned table spaces and bring together in a single annual partition. (for example tbs_2014_01, tbs_2014_02 - tbs_2014_12... all combine them into tbs_2014 as a tablespace)
Over the weekend, work of database gets executed that collects statistics that are obsolete, it collects all the segments that have been moved from the storage.
Given that the collection of statistics at the end of the week takes too long, I tried to find a smart way to collect statistics after each tablespace move rather than waiting for job to weekend which will take two or three days to complete.
1. is there a way to gather statistics at the tablespace level and collect statistics for all objects in this table space?
2. how to determine the overall stats of collection of statistics part?
That is, suppose I have move the tbs_2014_01 tablespace and collect statistics with global stats that could take 2 hours but it will be difficult to spend 2 hours for each stats global tablespace which in my opinion is not good and we should be collecting global stats only once.
3. any other advice?

I've not been asked to collect statistics to the tablespace but level to collect statistics after that finish objects move in storage.
Given the size of the data, it is difficult to gather all the statistics at the weekend so trying to understand another method to collect the statistics the weekend load will be less.
You can collect statistics object on an object by object basis level after that each object has been moved.
