Does oracle record table drops/purges ?

Hello,
I am using Oracle 11.2.0.3 Enterprise Edition and recently found certain users tables are missing. Does oracle record anything with respect to tables purged ? And in my case these are external tables. Pls revert back if I have to lookup in alert log or any v$ view. As far as I know if table is just dropped it can be found in dba_recyclebin ( not sure about retention) but I didn't find any information in that view. Any help would be great ! Thanks

Hi,
I am using Oracle 11.2.0.3
By default, some DDL commands are audited by default in Oracle 11g.
SQL> SELECT privilege from dba_priv_audit_opts where user_name is NULL;
PRIVILEGE
CREATE EXTERNAL JOB
CREATE ANY JOB
GRANT ANY OBJECT PRIVILEGE
EXEMPT ACCESS POLICY
CREATE ANY LIBRARY
GRANT ANY PRIVILEGE
DROP PROFILE
ALTER PROFILE
DROP ANY PROCEDURE
ALTER ANY PROCEDURE
CREATE ANY PROCEDURE
ALTER DATABASE
GRANT ANY ROLE
CREATE PUBLIC DATABASE LINK
DROP ANY TABLE
ALTER ANY TABLE
CREATE ANY TABLE
DROP USER
ALTER USER
CREATE USER
CREATE SESSION
AUDIT SYSTEM
ALTER SYSTEM
So, maybe you can try find out if another user dropped your tables making use of DROP ANY TABLE privilege. For this, you need to take a look at DBA_AUDIT_TRAIL view:
select * from dba_audit_trail where action_name = 'DROP TABLE' order by 5 desc;

What is the version of grant alter table, drop table to user in Oracle 10g?

Hi,
Oracle support "grant alter table and drop table" before, but I get the "invalid privilege" error in Oracle 10g. Oracle 10g have the "DROP ANY TABLE" and "Alter any table". Is these two means can drop and alter tables belonging to other users? How do I grant the total control (CRUD) of tables in the owner's schema to the owner in Oracle10g?
Thanks,
Jiang

CREATE TABLE privilege grants complete control on owner's tables :

User created.

TimeZone.getDefault().getID() does not exist in your Oracle database table V$TIMEZONE_NAMES???

Hi Everyone,
My Jdev version is 11.1.2.3.0.

But Jdeveloper got crashed so i reinstalled the same version but now none of the applications are running.
Its showing error as below:

Does IXOS record the name of the file uploaded in a R3 table?

Does IXOS record the name of the file uploaded in a R3 table?

Hi Christiana,
When you perform a file upload to IXOS, the filename is not being record. The archivelink table (toa*) will keep track the document type of the file only.
Hope this help.
thanks,

Like % in a query running on an Oracle Apps table with 8 million records

I am running the below query. As per the explain plan it is using the index on organization_id and inventory_item_id.
select segment1 from mtl_system_items where organization_id = 100 and inventory_item_id like '123456%'
It takes about 15 min to run this query which is a long time as this query returns values to the frontend created in asp. The webpage would time out by the time this query completes running. do you have any suggestions on how to run this query faster?

I'm having trouble recording a bass to go along with a recording I dropped into GB. I'm using an interface and I can hear the bass line, I've clicked on the 'record' button, but the sound does not record. What am I missing?

I have the bass connected to my imac with an interface.
I can hear the bass and I've clicked on the 'record' button, but the sound does not record.
Am I missing something ?
Please advise.
Mike

Double check all your audio settings.
System Preferences --> Sound --> Input should be set to your audio interface.
GB --> Preferences --> Audio/MIDI --> Input should be set to your audio interface.
With your track selected, open the Track Info pane, and select the Edit tab. Under input make sure that Mono 1 or 2 is selected (which number will depend on which input you plugged your bass cable into).

Duplicate Rows In Oracle Pipelined Table Functions

Hi fellow oracle users,
I am trying to create an Oracle piplined table function that contains duplicate records. Whenever I try to pipe the same record twice, the duplicate record does not show up in the resulting pipelined table.
Here's a sample piece of SQL:
/* Type declarations */
TYPE MY_RECORD IS RECORD(
MY_NUM INTEGER
TYPE MY_TABLE IS TABLE OF MY_RECORD;
/* Pipelined function declaration */
FUNCTION MY_FUNCTION RETURN MY_TABLE PIPELINED IS
V_RECORD MY_RECORD;
BEGIN
-- insert first record
V_RECORD.MY_NUM = 1;
PIPE ROW (V_RECORD);
-- insert second duplicate record
V_RECORD.MY_NUM = 1;
PIPE ROW (V_RECORD);
-- return piplined table
RETURN;
END;
/* Statement to query pipelined function */
SELECT * FROM TABLE( MY_FUNCTION ); -- for some reason this only returns one record instead of two
I am trying to get the duplicate row to show up in the select statement. Any help would be greatly appreciated.

Can you provide actual output from an SQL*Plus prompt trying this? I don't see the same behavior

Oracle temporary tables

Hi ,
we have a application for transfering data approx 1 million records from one schema to another. the data is first inserted into a table temporarily and after all the data is transfered the data is manually deleted from this table.
we are planning to replace this table with Oracle Temporary table. Can you please let us know if this would increase the performance and why???
Thanks & Regards
Saroj

In theory it should, but you won't know whether the difference is going to be noticeable until you try.
Oracle has to do much less work with global temporary tables. It knows no other sessions will be using the data so it does not need to bother with rollback segments or locks. It also does not bother with redo because there will not be a need to recover.

Selecting Records from 125 million record table to insert into smaller table

Oracle 11g
I have a large table of 125 million records - t3_universe. This table never gets updated or altered once loaded, but holds data that we receive from a lead company.
I need to select records from this large table that fit certain demographic criteria and insert those into a smaller table - T3_Leads - that will be updated with regard to when the lead is mailed and for other relevant information.
My question is what is the best (fastest) approach to select records from this 125 million record table to insert into the smaller table. I have tried a variety of things - views, materialized views, direct insert into smaller table...I think I am probably missing other approaches.
My current attempt has been to create a View using the query that selects the records as shown below. Then use a second query that inserts into T3_Leads from this View V_Market. This is very slow. Can I just use an Insert Into T3_Leads with this query - it did not seem to work with the WITH clause?    My Index on the large table is t3_universe_composite and includes zip_code, address_key, household_key.
CREATE VIEW V_Market as
WITH got_pairs    AS
     SELECT /*+ INDEX_FFS(t3_universe t3_universe_composite) */ l.zip_code, l.zip_plus_4, l.p1_givenname, l.surname, l.address, l.city, l.state, l.household_key, l.hh_type as l_hh_type, l.address_key, l.narrowband_income, l.p1_ms, l.p1_gender, l.p1_exact_age, l.p1_personkey, e.hh_type as filler_data, 1.p1_seq_no, l.p2_seq_no
     ,      ROW_NUMBER () OVER ( PARTITION BY l.address_key
                                  ORDER BY      l.hh_verification_date DESC
                  ) AS r_num
     FROM   t3_universe e
     JOIN   t3_universe l ON
            l.address_key = e.address_key
            AND l.zip_code = e.zip_code
          AND   l.p1_gender != e.p1_gender
             AND   l.household_key != e.household_key
             AND l.hh_verification_date >= e.hh_verification_date
SELECT *
FROM got_pairs
where l_hh_type !=1 and l_hh_type !=2 and filler_data != 1 and filler_data != 2 and zip_code in (select * from M_mansfield_02048) and p1_exact_age BETWEEN 25 and 70 and narrowband_income >= '8' and r_num = 1
Then
INSERT INTO T3_leads(zip, zip4, firstname, lastname, address, city, state, household_key, hh_type, address_key, income, relationship_status, gender, age, person_key, filler_data, p1_seq_no, p2_seq_no)
select zip_code, zip_plus_4, p1_givenname, surname, address, city, state, household_key, l_hh_type, address_key, narrowband_income, p1_ms, p1_gender, p1_exact_age, p1_personkey, filler_data, p1_seq_no, p2_seq_no
from V_Market;

I had no trouble creating the view exactly as you posted it. However, be careful here:
and zip_code in (select * from M_mansfield_02048)
You should name the column explicitly rather than select *. (do you really have separate tables for different zip codes?)
About the performance, it's hard to tell because you haven't posted anything we can use, like explain plans or traces but simply encapsulating your query into a view is not likely to make it any faster.
Depending on the size of the subset of rows you're selecting, the /*+ INDEX hint may be doing your more harm than good.

Finding exact time for table drop

Hi,
yesterday i dropped one of the important table ...i have rman backup...i want to use until time incomplete recovery method.. but i dont know the exact time of table dropped ..i tried alert and trace files ..but no use...
is their any method to find out the exact time of table dropped..
Oracle 9.2
Redhat 5.3
Thank u
selva..

So the database is not in ARCHIVELOG mode?
If you don't have the redo from the time in question, you haven't enabled auditing of DDL operations like DROP, and you don't have a DDL trigger that would have recorded the time of the drop, you're probably out of luck. Oracle won't have that information. You'll have to take your best guess.
If you were on a more recent version of Oracle, the dropped table would be in the recycle bin. But that wasn't available back in the 9.2 days.

How does oracle text differentiate between various document formats?

how does oracle text differentiate between text documents of various formats. does it read binary headers or a file extension is necessary?
please comment..

Oracle uses the inso_filter for document filtering as desribed in the documentation:
http://download-west.oracle.com/docs/cd/B10501_01/text.920/a96518/afilsupt.htm#625110
I did a little test (included below) where I copied a .pdf file to a file with a .test extension and it was still able to index it and search it, so apparently it does not need the file extensions and must read the header.

Does Oracle allows zero length string

Hi,
I tried to insert zero length string ('') into an Oracle table, a null value and a non-empty string. But I found that zero length string and null are stored as NULL in the column.
Create table test (col1 number(2), col2 varchar(10));
Insert into test values (1, 'hi');
Insert into test values (2, NULL);
Insert into test values (3, '');
Select * from test where col2 is null;
Result: 2 rows
Select * from test where col2 = '';
Result: 0 rows
Is this to do with some environment setting in SQL* Plus or does oracle doesn't allow zero length string?

Oracle treats '' as NULL.
There are frequent murmurs that some new version of Oracle is going to change this behaviour (I believe it's not ANSI-compliant) but I doubt that they will, as it will break too many old applications.

Where can I change the buffer size for LKM File to Oracle (EXTRENAL TABLE)?

Hi all,
I'd a problem on the buffer size the "LKM File to Oracle (EXTRENAL TABLE)" as follow:
2801 : 72000 : java.sql.SQLException: ORA-12801: error signaled in parallel query server P000
ORA-29913: error in executing ODCIEXTTABLEFETCH callout
ORA-29400: data cartridge error
KUP-04020: found record longer than buffer size supported, 524288, in D:\OraHome_1\oracledi\demo\file\PARTIAL_SHPT_FIXED_NHF.dat
Do you know where can I change the buffer size?
Remarks: The size of the file is ~2Mb.

Hi,
The behavior is explained in Bug 4304609 .
You will encounter ORA-29400 & KUP-04020 errors if the RECORDSIZE clause in the access parameters for the ORACLE_LOADER access driver is larger than 10MB and you are loading records larger than 10MB. Which means their is a another limitation on read size of a record which is termed as granule size. If the default granule size is less then RECORDSIZE it limits the size of the read buffer to granule size.
Use the pxxtgranule_size parameter to change the size of the granule to a number larger than the size specified for the read buffer.You can use below query to determine the current size of the granule.
SELECT KSPFTCTXPN PARAMETER_NUMBER,
KSPPINM PARAMETER_NAME,
KSPPITY PARAMETER_TYPE,
KSPFTCTXVL PARAMETER_VALUE,
KSPFTCTXDF IS_DEFAULT,
KSPPIFLG MODIFICATION_FLAG,
KSPFTCTXVF VALUE_FLAG
FROM X$KSPPI X, X$KSPPCV2 Y
WHERE (X.INDX+1) = KSPFTCTXPN AND
KSPPINM LIKE '%_px_xtgranule_size%';
There is no 'ideal' or recommended value for pxxtgranule_size parameter, it is safe to increase it to work around this particular problem. You can set this parameter using ALTER SESSION/SYSTEM command.
SQL> alter system set "_px_xtgranule_size"=10000;

Fastest way to load csv into oracle BE table

I have csv file which is having 10 million records in it . what is the fastest approach to load this data to oracle BE table .
I am using Oracle9i Enterprise Edition Release 9.2.0.7.0 - 64bit Production With the Partitioning, OLAP and Oracle Data Mining options .
csv format
first_name,last_name,occupation,address
above all the fields are of varchar data type.
I have tried to use external table while inserting its taking too much time .
Thanks

hi,
You can use sql loader.
options (skip=1)
LOAD DATA
INFILE 'csv file path'
truncate /append
INTO table table_name
FIELDS TERMINATED BY ','
OPTIONALLY ENCLOSED BY '"'
trailing nullcols
column name ,
column name,
column name
{code}
Create this file as ctl(control file.) on the lcoation where your csv file is.
Execute it by goint to the path where your csv file resides.
{code}
cmd
cd path where your csv file resides
sqllder userid=username/password@database name control=your_control_file_name
{code}
