Collect statistics of concurrent request schema...
HelloCollect statistics of schema ('ALL') taken same duration long concurrent request not completed after 8 hours, too help me in this regard the collection of statistics for all schemas in Oracle Ebs environment.
Application: Oracle Ebs R12 (12.1.2)
DB: 11.1.0.7
OS: Linux5 * 86 X 64
with impatience.
Kind regards

Hi Hussein
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
exec dbms_stats.unlock_table_stats('SYS','WRH$_SYSSTAT');
Kind regards

Collect statistics in oracle 11 g
Hi all
OPERATING SYSTEM: AIX
DB: 11GI 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
SphinxHello
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,.

Collect statistics of schema is no longer can be cancelled but Phase set EXECUTION
Hi all.
After a work of statistics gather scheme was started inadvertently, I canceled it. Now we can see that the parent process is blocked in:
Phase = running
Status = in pause.
If we try to cancel, we see "request * can no longer be cancelled.» The concurrent Manager process that running this application has ended abnormally. The ICM will mark this request as completed with error.
Do we need to worry about this? It is not really 'ongoing'. It is expected to run again next weekend.
Is it safe to leave it? Or do I take action? I don't think anything more needs to be done, but others disagree.
I thank.

Hello
1.) it not automatically runs through Planner if you cancel it this time, it must be planned again.
(2.) to check if it still has the substantive session the session of $ v
Select oracle_process_id from the fnd_concurrent_requests where request_id = 'collect the id of the request;
Select * from session $ v where paddr = (select addr from process $ v where the spid = 'oracle_process_id_obtained_above');
kill sessions for the sid above - this will give zero if its not actually running.
3.), you can manually update the completed fnd_concurrent_requests table
SQL > update fnd_concurrent_requests set phase_code = 'C', status_code = has ' where request_id = - this should update only 1 file for the schema request gather; -SQL > commit; (Remember to commit)
(4.) to ensure that all managers are on the rise (actual = target) and other concurrent requests complete with phase and code status as C and C code.

However, we have developed a few modules like Oracle Financials, SCM, OPM, HR, but 'Schema statistics gather' CP is running for 10:30 hours. The parameters are the following:
Schema name: ALL
Estimate for %: 10
Degree: Null
Flag of backup: NOBACKUP
ID of the request to reboot: Null

ArizHow can I set this program to better performance? How can I include only the modules that are being implemented not all (patterns)?
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%

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.

We met the performance issue on some lots.
Can it be attributed to a statistic of outdated diagram? We have collected statistics schema 1 months ago.
How often should collect us statistics of schema?
Thank you very much
KinzWell, I guess the query was degraded. Do you mean that it was always like that? In this case, you must take a very different approach: you can set from the beginning.
First get the AWR SQL report. I already told you to do. Then check out some more detail. Run the query with this suspicion,
/ * + gather_plan_statistics * /.And then to get the execution statistics with
Select * from table (dbms_xplan.display_cursor (format-online 'allstats')) last;Yes, it will take an hour or two to run, but it's the best way to get to the truth.

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.

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.

BI Publisher Tor run as a concurrent request of the eBS product a wrong exit Excel
We have a BI Publisher report that is saved as a concurrent request to eBS (version R12). The report model is a model of .rtf. Default report output is in PDF format, but users can choose Excel in another format of output. The report is properly display all data correctly when the output format is PDF, but when the output is Excel, we have problems with the display of data in certain columns. I did some research and I see that there are known limitations with models rtf producing an Excel output. I tried some of the methods suggested to work around formatting problems, however, I'm not able to solve these problems. I see that it is recommended to use Excel for Excel output binary patterns. How to create a binary schema Excel? I have BI Publisher Desktop version 10.1.3.4 on my PC. I am able to create BI Publisher rtf templates, do I need to create templates Excel, or whatever is needed to produce the output Excel?
Thanks for any help/suggestions.
EmilyThere is a link in 444604.1 that shows you how to use Excel to create binary layouts - these can provide better exits that RTF, but then the output can be in Excel

If this isn't a lot of time, you can activate Event 10046 (using dbms_monitor, perhaps) to level 4 (lie).
This can tell you exactly what the session is done when it crashes.Note: If the default grouping is "gather stale", which would explain why the work may run successfully several times before a critical table is going stale and causes an accident on the next collection.

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

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.

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.,.
