• How to collect statistics on the table for tables in a different schema

  Hi all
  
  I have a table in a schema, and I want to collect statistics for the table in a different schema.
  
  I gave GRANT ALL ON SCHEMA1. T1 TO SCHEMA2;
  
  And when I tried to run the command to collect statistics to help
  
  DBMS_STATS. GATHER_TABLE_STATS (OWNNAME = > 'SCHMEA1', TABNAME = > 'T1');
  
  The function will fail.
  
  Is there a way we can collect statistics of the table for tables in a schema into another schema.
  
  Thank you
  MK.

  You must grant analyze to schema2.

• 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?

  @sol.beach... Thanks for your comments...

  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.

• 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:
  BANNER
  --------------------------------------------------------------------------------
  Oracle Database 11 g Enterprise Edition Release 11.2.0.1.0 - 64 bit Production
  PL/SQL Release 11.2.0.1.0 - Production

  AMT for Linux: Version 11.2.0.1.0 - Production
  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.

• What is advised to collect statistics for the huge tables?

  We have a staging database, some tables are huge, hundreds GB in size.  Auto stats tasks are performed, but sometimes it will miss deadlines.

  We would like to know the best practices or tips.

  Thank you.

  Improvement of the efficiency of the collection of statistics can be achieved with:

  1. Parallelism using
  2. Additional statistics

  Parallelism using

  Parallelism can be used in many ways for the collection of statistics

  1. Parallelism object intra
  2. Internal parallelism of the object
  3. Inner and Intra object jointly parallelism

  Parallelism object intra

  The DBMS_STATS package contains the DEGREE parameter. This setting controls the intra parallelism, it controls the number of parallel processes to gather statistics. By default, this parameter has the value is equal to 1. You can increase it by using the DBMS_STATS.SET_PARAM procedure. If you do not set this number, you can allow oracle to determine the optimal number of parallel processes that will be used to collect the statistics. It can be achieved if you set the DEGREE with the DBMS_STATS. Value AUTO_DEGREE.

  Internal parallelism of the object

  If you have the 11.2.0.2 version of Oracle database you can set SIMULTANEOUS preferences that are responsible for the collection of statistics, preferably. When there is TRUE value at the same TIME, Oracle uses the Scheduler and Advanced Queuing to simultaneously manage several jobs statistics. The number of parallel jobs is controlled by the JOB_QUEUE_PROCESSES parameter. This parameter must be equal to two times a number of your processor cores (if you have two CPU with 8 cores of each, then the JOB_QUEUE_PROCESSES parameter must be equal to 2 (CPU) x 8 (cores) x 2 = 32). You must set this parameter at the level of the system (ALTER SYSTEM SET...).

  Additional statistics

  This best option corresponds to a partitioned table. If the INCREMENTAL for a partitioned table parameter is set to TRUE and the DBMS_STATS. GATHER_TABLE_STATS GRANULARITY setting is set to GLOBAL and the parameter of DBMS_STATS ESTIMATE_PERCENT. GATHER_TABLE_STATS is set to AUTO_SAMPLE_SIZE, Oracle will scan only the partitions that have changes.

• Collect statistics for a Table

  Hello

  If a corporate table has not changed (No. DML) in the last 10 days, will be the collection of default oracle job stats

  DBMS_STATS.GATHER_DATABASE_STATS_JOB_PROC

  yet collect statistics in this table?

  The answer is no, unless you have changed the default optimizer stats collection of statistics because approximately 10% of the data must have undergone change before that table is elgible for new statistics.

  See the next topic in the Performance and Tuning section 14.2.1 GATHER_STATS_JOB Manual:

• Collect statistics on each partition - 11.2.0.3?

  Hello

  Using 11.2.0.3 and partition oracle to Exchange loading to load about 7 million rows in each partition.

  Concluding that if you run the query against the partitions loaded the same day, then expect that the query slower than if a day until that data gathers stat automatically.

  Thought would try to use

  DBMS_STATS.gather_table_stats ('schema', 'table_name', partname = > 'partition_name'); but ultra slow.

  but when look at sql_plan_monitor seems to be analyzes all partitions.

  How can we ensure fair stats collection is quick to ensure that his stats updates for the last partition after loading?

  Thank you

  Granularity depends on:

  http://docs.Oracle.com/CD/E11882_01/AppDev.112/e40758/d_stats.htm#ARPLS68582

  If you specify "PARTITION", then he will stick to the partition level statistics.

  You must then consider what happens to the OVERALL statistics and when?

• 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,.

• 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.

• Have we not collect statistics after reorg?

  Hello
  I did a reorg to a few tables and indexes. After the reorg, I need to collect statistics for these objects?
  
  Database version: 11.2.0.2
  
  Kind regards
  Sarayu K.S.

  ... [url http://docs.oracle.com/cd/B28359_01/server.111/b28310/tables006.htm#i1106606] all the statistics in the table become invalid and new statistics should be collected after the removal of the table.

• How can I use statistics for all the tables in a schema in SQL Developer? and how long will it take on average?
