Table Stats Copy Amount Sub-partition To Save Load On System - Error?
Oct 10, 2012
i have a large OLTP database and we are doing table stats copy amount subpartition to save the load on system. while doing an copy default subpartition stats: I see the following error:
SQL> exec DBMS_STATS.COPY_TABLE_STATS('cusms','STATUS_HIST','P_VDEF_10_2012_S100','P_VDEF13_10_2012_S100',force=>true);
BEGIN DBMS_STATS.COPY_TABLE_STATS('cusms','STATUS_HIST','P_VDEF_10_2012_S100','P_VDEF13_10_2012_S100',force=>true); END;

I have 2 tables with same no of column and range partition based on date.At the end of month i want to copy the data of one table to another table.Instead of copy the data i want to copy the data of one partition completely to another table partition ..
I have used the above to get a copy of schema stats and gather new stats for specific tables into a STATS TABLE in my personal schema. What I want to do now is use this stats table to generate plans for queries where I believe stats are off. Is it even possible? To be clear, I do not want to import stats because this replaces the stats currently there. I just want to point the CBO to my stats table for generating plans.
there was a session parameter I could set to tell oracle to use my stats table when generating plans, or an explain plan clause I could use or a DBMS_XPLAN paramter I could provide that would tell these tools to use my stats table when generating a plan, or even some way to tell autotrace. But I have found none of this.
I'm using Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production and TNS for Linux: Version 11.2.0.3.0 - Production.Requirement is to create a script to add a LIST partition to some selected tables in a schema (tables do not have data, they are not partitioned). There are about 300 such tables (can vary) and their names are maintained in a separate table. Example -Existing table
-CREATE TABLE test_part(id number (2), name varchar2(20), audit_userid number (9)); Expected table -CREATE TABLE test_part(id number (2), name varchar2(20), audit_userid number (9)) PARTITION BY LIST (audit_userid) (PARTITION p1_audit_userid VALUES (1));
Ultimate goal is to add more partitions based on the amount of data to be populated.
I am on a font manager project. One of the features is to install the new font file. My understanding by "install" is to copy the file to the system directory Windows/fonts (correct me if I am wrong in this part). When I tried to use the java copy file api to do so, not surprisingly I got the access denied exception.
1. How can I do a "force-copy" of file into the system directory?
2. If that's not proper way, how can I create a "shortcut" like a softlink of the file into the system directory?
11.2.0.3...just trying to learn the syntax. I have not worked with IOTs and I am exploring a feature I have not really used to try to learn something new. I know about intervals.This exact split syntax below, works on a heap table without errors. When I run the following split against a regular heap table it works.
alter table MYTABLE split partition "FUTURE" at ( to_date('09_MAY_2013_13','DD_MON_YYYY_HH24' ) ) into ( partition "B4_09_MAY_2013_13", partition "FUTURE" ) update global indexes * ERROR at line 1: ORA-00932: inconsistent datatypes: expected BINARY got NUMBER
During STATS gather running for the table, unknowingly i deleted the old stats using EXEC DBMS_STATS.DELETE_TABLE_STATS. I would like to know will it affect the stats gather job currently running for the table and whether my stats will be gathered successfully.
I got following error when i am gathered stats on Schema level.

I think that performance better partition table than non-partition table. How to assure partition table is better than non-partition table at SELECT operation?
I have compare a specific query EXPLAIN PLAN at partition table and non-partition table. both tables data is same. Is it true way or not?
I have a table that partitioned into six partitions. each partitions placed in different table space and every two table space placed it on a different hardisk
when I will do query select with the non-partition keys condition, how the search process ? whether the sequence (scan sequentially from partition 1 to partition 6) or partition in a hardisk is accessed at the same time with other partition in other hardisk. ( in the image, partition 1,4 accessed at the same time with partition 2,5 and 3,6)
Can i alter the table to create partition on non partition table, i have tried and could not create it. Do we have some other means to do it as this is the live table and cannot drop them else will lose the data.
I want to adjust 2900 against certain amount from table on fifo basis.
DROP TABLE ABC CREATE TABLE ABC(ID NUMBER PRIMARY KEY,AMT NUMBER); INSERT INTO ABC VALUES(1,1000); INSERT INTO ABC VALUES(2,2000); INSERT INTO ABC VALUES(3,3000);
Can i do it using SQL. I know that it can be done using PL/SQL but i just wanted to confirm if its possible using SQL.
Can I add range sub partition to a hash partition table. Example like this.
CREATE TABLE test ( test_id VARCHAR2(10 ) , test_TYPE VARCHAR2(5) , CREATE_DATE date ) partition by hash (test_id, test_type) Partitions 3 SUBPARTITION BY RANGE (CREATE_DATE);
When Tried, I am getting syntax error as invalid option.
When I am trying to insert record from tbl_mittal into tbl_temp table. I am facing "ORA-14400: inserted partition key does not map to any partition" error
SQL> insert into tbl_temp select * from tbl_mittal; insert into tbl_temp select * from tbl_mittal * ERROR at line 1: ORA-14400: inserted partition key does not map to any partition
AS tbl_mittal is having hugh number of records so I am providing only few rows from tbl_mittal table as test data.
I have doupts in gathering stats on table. I analyzed one table it took 2 hours first time.. the same table after one week later i analyzed, its got completed within 45 minutes.. I don't know exact reason why i got completed very soon. Is there any specific reason?
When we upgrade from 10g to 11g oracle upgrades the stats table by EXECUTE DBMS_STATS.UPGRADE_STAT_TABLE('OWNER','TABLE'); But When we import from 10g to 11g do we need to upgarde the stats table??
I am trying to generate some statistics on tables connected by a dblink. I know with oracle you have table_columns which you can reference and pull some stats from.
Trying to get the column count and record counts for each table connected by a dblink. I have tried these queries below to see if I could see any db properties: (some just to try something different)
select * from "table_owner".table_column@dblink ; select * from "status"@dblink; select /*DRIVING_SITE(a) */ count(*) from @dblink a;
What is the best method to finding this out without spending a lot of time? I have over 30 tables which are with large record sets and would love to learn a faster approach then pulling a sample table and doing a manual count and query for each table to count the rows.
We are running 11g (11.2.0.3)We have a "working table" that is empty at the beginning of the day.Then we start adding rows (insert) with a key column called STATE with a value of 100.At the same time, there are other apps that pickup data in state 100 , process that data and change that state to 200 or 300.There is also another app that pickup data in state 200 , process that data and change that state to 300 or 400.
So in summary, the data on that table is at the beginning empty, then all the rows are in state 100, they slowly move to different states (200, 300, etc) and by the end of the day, they are all in 400.
My question is what would be the best way to collect stats on this table?
I was thinking to create an hourly job to collect stats on that table: exec dbms_stats.gather_table_stats ( ownname => 'SCOTT', tabname => 'WORK_T
Is it possible for the DBMS_STATS "LIST STALE" command to show a stale partition but NOT have its table show as stale?
I had a scenario where the table itself AND 1 partition showed as stale. I ran a fnd_stats gather table stats just on that 1 partition. Once it was completed it showed the partition to no longer be stale. it also showed that the table was no longer stale. so I guess I do not need to run stats on the whole table as well?
so if this is the case, when would I need to run stats on the full partitioned table if running it on the partitions themselves removes the staleness of the table?
How to find the size pf a partition in a partition table?I guess we need to query views like dba_tab_partitions but I am not very sure. will running dbms_stats.gather_table_stats('schema_name,'table_name,'partition_name')
Our UNDO space remains at a high level 85 to 95 percent. We keep adding database files and it doesn't seem to go down significantly. When we do a backup of the system where we shut the database down, it does go down some but then within a week or so it is back up again.
I developed a form in forms9i, at the time of data entering form is not showing any ERROR messages or SAVE RECORD message and when I press exit button it is asking "DO YOU WANT TO SAVE THE CHANGES YOU HAVE MADE".
I have checked my PRIMARY KEY field and there is no mistake and value is populating at PRE INSERT.
PROMPT CREATE TABLE tst_fetch_vendor_data CREATE TABLE tst_fetch_vendor_data ( vendor_data_seq_no NUMBER NOT NULL, study_seq_no NUMBER NOT NULL, vendor_record_seq_no NUMBER NOT NULL, control_column_seq_no NUMBER NOT NULL, resolved_value VARCHAR2(4000) NULL, original_value VARCHAR2(4000) NULL, transaction_user VARCHAR2(30) NOT NULL, [code]....
Its just a temporary table, in which data comes and goes. I am using this in middle of a process.I am using it in a process like below--
--EXECUTE IMMEDIATE 'TRUNCATE TABLE TST_FETCH_VENDOR_DATA DROP STORAGE';
insert /*+ append */ into tst_fetch_vendor_data (select * from vendor_data vd where vd.control_column_seq_no in (select control_column_seq_no from temp_control_column)); dbms_stats.gather_table_stats('EPDSYSREP','TST_FETCH_VENDOR_DATA',ESTIMATE_PERCENT=>100, METHOD_OPT=>'for all indexed columns size auto',CASCADE=>True);
code to use that table..This table can contain data from 0 to 108000000 records.Now my questions are-
1. How much should I select sampling size (currently its 100%)Can I use dbms_stats.auto_sample_size, what will be the effect?
2. dbms_stats is good approach or should I use dynamic sampling.
3. what about the approach using CTAS instead of inserting data through insert.
4. What about pl/sql table with index or with clause query.
5. Do I need to rebuild index after inserting data into table.
I load a table through sql loader which takes nearly 14 min for 8-9 millions records, once the records complete i run the analyze table compute statics to gather stats and it takes nearly 15 min. is there any ways so that i can reduce the stats timing. the stats collection command runs from other schema not from where the table is residing.

We need to connect to an Oracle database from an ASP web page and I downloaded and installed ODAC112021.zip to a Window 2003 server; can connect OK I sent the zip to co-worker in another state and he installed it on slightly older build of 2003 server and we get the following error
"The setup routines for the Oracle in OraClient11g_home1 ODBC driver could not be loaded due to system error code 14001"
Only saw one post on OTN discussion and msot mention another error (998) [URL]
