• Many gather schema Stat CR on R12

  Hi, gurus:

  Today, I saw that there are many Stats to collect schema CR completed these days. They all run "as soon as possible." Who/what launched?

  EBS: 12.1.3

  OS: Linux

  DB: 11.1.0.7

  Thank you.

  Hello

  Help without politeness is not actually qualify as aid, is it not?

  You can find all of the application of a particular application/program competing using the query:

  SELECT DISTINCT User_request_set_name

  OF FND_REQUEST_SETS_TL

  WHERE request_set_id IN

  (SELECT request_set_id

  OF FND_REQUEST_SET_PROGRAMS

  WHERE concurrent_program_id =

  (SELECT CONCURRENT_PROGRAM_ID

  OF fnd_concurrent_programs_tl

  WHERE upper (USER_CONCURRENT_PROGRAM_NAME) = upper ("& Enter_Prog_name")));

  The above query was extracted from the link:

• collect program of conc. schema stat taking too long

  Hello
  I ran to gather stats conc schema. program this morning. Its already close 02:40 minutes and the program is still ongoing. How long does take. And I guess that's the first time I run this prog on this machine.
  
  The parameters used are
  
  ALL 10 NOBACKUP LASTRUN COLLECT THERE
  
  It's R12.0.6 VISION long back (back of 7 months) for testing. Not many use it. And now the performace is slowww for ORDER MANAGEMENT module. And to collect statistics of schema was not planned. So I ran Gather scheme and it takes so long. I fear that I will not make the system much more slow coz in 2 days we had the demo.
  
  can I cancel this request. or should I wait some time yet.

  can I cancel this request. or should I wait some time yet.

  Its best way to cancel them now and run it at night when the system is not the use by users, coz it may be cause performance problem

• Exclude MV grouping scheme stats table

  Hey,.
  I'm running the daily statistics gathering the procedure below.
  But it runs at the same time with a MV that's refreshing, and it is a failure because of that.
  
  Is it possible to exclude the view materialized since the procedure diagram below stats?
  
  BEGIN
  
  DBMS_STATS.gather_schema_stats (ownname = > 'SCOTT', estimate_percent = > dbms_stats.auto_sample_size, degree = > 2);
  
  END;
  
  
  This forum works on Oracle 10.2.1.0 on Linux env.

  You can lock the statistics on tables that you do not want to ask for more stats: dbms_stats.lock_table_stats
  http://download.Oracle.com/docs/CD/B19306_01/AppDev.102/b14258/d_stats.htm#i1043993
  Then run that the above command will not calculate its stats on these objects.

• Gathe schema Stats does not.

  Hi all
  
  31%
  
  exec dbms_stats.gather_schema_stats ('PROD2');
  
  
  But when I count the tables and compare it with the table num_rows, some num_rows tables do not correspond with the actual number :(
  
  How I solve you this problem?
  
  
  Thank you very much

  I don't know why I can't count the imp_log against the exp_log? because I missed once the number of some tables. that were not properly loaded.

  I'm not sure that understand what you're saying here. Why can you not compare log of export data and the import log? Or the import for scanning errors log?

  Or you have a better way to do this audit activity?

  Assuming that you are excluding export it and import newspapers, which is what I would use, do a COUNT (*) on each table. It's faster, easier and more obvious than the DBMS_STATS call just to fill the NUM_ROWS in DBA_TABLES column.

• Schema change

  Hi all

  This is my lab to make the base Oracle administrator.

  I have created a db - "orcl" administered by SYS and has also created a "Usr2" user

  The default schema of Usr2 is SYS.

  I tried SET SCHEMA statement

  "SCHEMA SET USR2";

  but the return

  line 1: jump of SQLPLUS command: schema set USR2;

  May I know if it is possible to change the default schema of USR2?

  Do I have to set everything i connect to db?

  ALTER SESSION SET CURRENT_SCHEMA = USR2;

  I also have a solution of relaxation.

  Thank you very much.

  Did you know you can copy text from a command prompt, and post it in a text message?  If you do this and do that posted the text in the Courier font, it will be much easier to read than a screenshot.  Especially when this screenshot includes a lot of empty real estate. Live by the GUI, die by the GUI.

  For your technical problem and your mistakes of interpreting results...

  When you connect 'as sysdba' you are authenticated by your information identification of the BONE and always connected as SYS.  You could put ANY user and a password... those of existent and always connected as SYS when you use the option 'as sysdba.

• Module FNDGSCST: collect statistics of schema

  I had a problem similar to this, and I remember drew to a close with name change or drop the object in question.

  Surely, there MUST be a way for that:

  1. concurrent demand Gather schema Stats can still function (with the object with this name, always on the database)

  2 preferably also the contractors that object as well (so, not as a 'fix' have this object being excluded a request competitor buggy)

  It's on a 12.1.3 environment.

  I thought that the cause of this problem is someone with exotic filenames on objects additional eBS, without thinking about the consequences. I have no idea about the source of this particular object (I guess there is more than 1).

  Is there a definitive solution to this problem? Concurrent demand to collect Stats of scheme has had a very bad reputation, not only thanks to this bug. Problem is that it stops on ALL issues, which is another bug.

• priority to collect simultaneous stat program

  Hello
  
  I would like to know if
  
  1. I can't run gather schema stats 'ALL' simultaneous program without any other other interfereing concurrent programs. The idea is just to have a good performance of the stats together without any error.
  
  2. is running gather stats conc program effect the performance of the system.
  
  3. with 10% it will rebuild the index associated as well.
  
  3. prior to going for above, is there a way I can check the current statistics.

  Error ORA-20005 #1: ERROR: while GATHER_TABLE_STATS:
  object_name = * ORA - 20005: Statistics object are locked (stattype = ALL) *.

  This indicates that one (or more) of database objects are locked and you will need to run "Gathering statistics for schema" when not one/process can access these objects.

  -to solve this problem, we have unlocked the statistics using the script
  exec dbms_stats.unlock_schema_stats ('schema_owner');

  ERROR
  Could not properly update the history table - fnd_stats_hist.

  Note: Please do not disseminate the contents of the documents of MOS because this violates the agreed strategy of support Oracle.

  Now, I would like to know because I've truncated the table FND_STATS_HIST... What happens to the statistical information of patterns that I've not met stats for? should I restore the backup table omit the patterns that I had just finished Gather stats for?

  You can purge/truncate table because it contains historical data only - http://etrm.oracle.com/pls/et1211d9/etrm_pnav.show_object?c_name=FND_STATS_HIST&c_owner=APPLSYS&c_type=TABLE

  Also, I cancelled the simultaneous application of one of the schemas in the middle... but the dba_tables last_analyzed always displays the current date for all tables. So how can I check for which tables / indexes the gather stats do not work?

  LAST_ANALYZED displays the current date, means that the table was already analyzed.

  So, this and then check

  You can check it using this:

  select sys_context('USERENV','SESSION_SCHEMA') from dual;

  THE QUESTION IS, in all these verification option, I GOT AUDIT TRAIL for access, no session, IE.  When I do something be checked, each access obtained an audit NOT by session trail, WHY, IT CONFUSED ME a lost!

  OK, I know it very well:

  http://docs.Oracle.com/CD/E11882_01/network.112/e16543/whatsnew.htm#CJAGCGGE:

  Change to AUDIT BY SESSION

  The SESSION clause of the present AUDIT report writes an audit record for each audited event. In previous versions, has written a record audit for all SQL statements or operations of the same type that were performed on the same schema objects in the same session of the user SESSION. Now, by SESSION and BY ACCESS write an audit for each audit record. In addition, there are records of separate audit for OPENING and closing of SESSION events. If you omit the clause BY the ACCESS, then BY SESSION is used by default.

  Generating SESSION audit record is different from the audit OF ACCESS record. Oracle recommends to include the clause BY ACCESS for all directions of AUDIT, which translates into a more detailed audit record. In the case of logging events, the timestamp of the audit record has a greater precision than in previous versions.

  Note that this change applies to schema, statement options object audit options and system privileges that audit SQL statements other than data definition language (DDL) statements. Oracle database always checked using the clause BY ACCESS on all statements SQL and access privileges that check a DDL statement.

• SQL very slow Performance after upgrade.

  We have recently upgraded to 10.2.0.5 for 11.2.0.1, and the performance of some of our queries SQL slowed considerably. For example, a query that works almost instantly in 10 g takes more than 30 seconds to 11 g. When I run an autotrace, the LAST_CR_BUFFER_GETS in 10g is 1067 and 11 g, it's 621006!
  
  I don't know why the exact same query would produce different results. I'm sure it's a matter of adjustment, but any ideas on where to start would be appreciated.

  This command will gather his stats, but the default values can be different between 10g and 11g. You should check out what they are. Here are the ones I have change:

  select dbms_stats.GET_PREFS('AUTOSTATS_TARGET') from dual;
  select dbms_stats.GET_PREFS('CASCADE') from dual;
  select dbms_stats.GET_PREFS('ESTIMATE_PERCENT') from dual;
  select dbms_stats.GET_PREFS('METHOD_OPT') from dual;
  select dbms_stats.GET_PREFS('NO_INVALIDATE') from dual;
  select dbms_stats.GET_PREFS('GRANULARITY') from dual;
  select dbms_stats.GET_PREFS('PUBLISH') from dual;
  select dbms_stats.GET_PREFS('INCREMENTAL') from dual;
  select dbms_stats.GET_PREFS('DEGREE') from dual;
  

  And then I change them to:

  EXEC DBMS_STATS.SET_GLOBAL_PREFS('AUTOSTATS_TARGET','ORACLE');
  EXEC DBMS_STATS.SET_GLOBAL_PREFS('CASCADE','TRUE');
  EXEC DBMS_STATS.SET_GLOBAL_PREFS('ESTIMATE_PERCENT','100');
  EXEC DBMS_STATS.SET_GLOBAL_PREFS('METHOD_OPT','FOR ALL COLUMNS SIZE 1');
  EXEC DBMS_STATS.SET_GLOBAL_PREFS('NO_INVALIDATE','FALSE');
  EXEC DBMS_STATS.SET_GLOBAL_PREFS('GRANULARITY','ALL');
  EXEC DBMS_STATS.SET_GLOBAL_PREFS('PUBLISH','TRUE');
  EXEC DBMS_STATS.SET_GLOBAL_PREFS('INCREMENTAL','TRUE');
  

  Your preferences may be different, but we do not use histograms and we always 100% of the data samples. Find out what the other parameters in the Oracle documentation.

  Good reading on this topic [url http://www.ora00600.com/scripts/statistics/restore_schema_stats.html] restore schema stats and this one on [url http://www.ora00600.com/scripts/statistics/gather_system_stats.html] collect statistics of the system.

  When you gather stats, you may need to clear the shared pool afterwards so that they SQL request are difficult, analyzed again and use the stats again. Use the ALTER SYSTEM FLUSH SHARED_POOL but probably better to do so in a period of low activity.
