DML Error logging table in Set base mode

Hi all,
In ETL data errors can be handled thru error logging table. Like this example given in the document-
INSERT /*+ APPEND PARALLEL */
INTO sales SELECT product_id, customer_id, TRUNC(sales_date), 3,
promotion_id, quantity, amount
FROM sales_activity_direct
LOG ERRORS INTO sales_activity_errors('load_20040802')
REJECT LIMIT UNLIMITED
In this example bulk loading is possible even in the presence of errors. The data errors will go in table 'Sales_activity_errors'.
I want to generate this kind of coding in OWB in set base mode. For that i have to create a error logging table in target schema. How can I reference this table in a mapping? can it be done by shadow table? It's a very important feature in ETL for bulk loading. Is it available in OWB in set based mode?
Guyzz please check this out and help me..
Regards,
Sumanta

Hi,
I am not sure if the DML error logging method is avaliable to be used in OWB 10g R2. You can use the data rule method. Create the data rules on the target table. Deploy it from OWB. Create your mappings and then execute them. Two insert statements will be generated. One for loading the target table for loading records where no rules are violated. The other for loading the <target table>_ERR for loading records where one or more error rules are violated.
Both these statements do a bulk loading. So your purpose will be solved.
Again you can use the splitter method that has already been mentioned.

DML Error Logging Tables?

How can I use DML Error Logging Tables with OWB10gR2 (in tab-definition and mappings)?
btw: what really is a shadow-table?

Hi,
What you can do to solve this is to add a Pre-mapping to your mapping which calls a procedure that alters the constraint on the target table in which you use the "EXCEPTIONS INTO <error_table> " clause.
like:
PROCEDURE "ENABLE_CONSTR_WITH_EXCEPTIONS"("P_TABLE" IN VARCHAR2, "P_CONSTRAINT" IN VARCHAR2) IS
v_table            varchar2(30) := p_table;
v_constraint          varchar2(30) := p_constraint;
v_command           varchar2(200);
e_CannotValidate      exception;
PRAGMA EXCEPTION_INIT(e_CannotValidate, -2437);
-- main body
BEGIN
/* Enable Constraint and write error into exception table */
BEGIN
    v_command := 'ALTER TABLE ' || v_table || ' ENABLE CONSTRAINT '|| v_constraint ||' EXCEPTIONS INTO exceptions';
    execute immediate (v_command);
    commit;
END;
    EXCEPTION
        WHEN e_CannotValidate THEN
           -- In my case when Unique Constraints are violated I will delete the duplicates.
           DELETE_DUPLICATES(v_table, v_constraint);
        WHEN OTHERS THEN
            NULL; -- enter any exception code here
END;
-- End of ENABLE_CONSTR_WITH_EXCEPTIONS;Greetz,

How to find if an error log table is related to a table....???

Hi,
In Oracle 10g , maybe in older version too, there is the capability to create an error log table using the dbms_errlog package and create_error_log procedure...
For exaample:
exec dbms_errlog.create_error_log('EMP','EMP_ERROR')
How to find afterwards that the table EMP has a related table EMP_ERROR where errors during the inserts/updates on table EMP are registered...?????
Of course the column names in EMP_ERROR table are the same as in EMP .... but it's time consuming method to search like this way...!!!!!
SQL> exec dbms_errlog.create_error_log('EMP','EMP_ERROR');

Dml error logging for tables in 10.2.0.5

Hi experts,
I have problems loading error records into the shadow table specified in the configuration window for tables. Upon executing the mapping, the execution results show warnings with the error records but these records were not moved to the shadow/error table.
The actual scenario is: I specified a non-null data rule on the supplier_code column in the supplier table. Inside the mapping where I used this supplier table, I choose the option "Move to error" for this non-null data rule. Upon executing, it seems that owb treats these as warnings and not errors and thus did not propagate them to the error table. Anyone has any suggestion as to how to make use of the error tables in owb?

DML error logging is generated for set-based PL/SQL mappings if the following conditions are satisfied:
1. the Error table name property is set for the operator (table/view/mv)
2. the PL/SQL Generated Mode of the module that contains the mapping is set to 10gR2 and above or Default.
If the value is set to Default, ensure that location associated with the module has the Version set to 10.2 or above.
When you use a data object in a mapping, the Error Table Name property for this data object is derived from the shadow table name property of the data object . If you modify the error table name of a data object (using the shadow table name property), you must synchronize all the operators bound to this data object.
If you are still facing the issue then provide your email and I can send a simple example of data rule mapping in OWB 10.2.0.5

Use global temp table for DML error logging

our database is 11.2.0.4 enterprise edition on solaris 10
we are wondering if anyone has an opinion of or has done this before, to use a global temp table for DML error logging. We have a fairly busy transactional database with 2 hot tables for inserts. The regular error table created with dbms_errlog has caused many deadlocks which we don't quite understand yet. we have thought using global temp table for the purpose, and that seemed to work, but we can't read error from the GTT, the table is empty even reading from the same session as inserts. Does anyone have an idea why?
Thanks

The insert into the error logging table is done with a recursive transaction therefore it's private from your session which is doing the actual insert.

DML Error Logging with multiple tables = OALL8

I have a mapping that, via a splitter, loads 3 tables. This mapping works perfectly.
Recently we upgraded to OWB 10.2.0.3 so we decided to make use of the new feature of DML error logging. So three error-tables where created and the "error table name" property of each table was entered. When re-creating this mapping in the database the following errors occur: "State of OALL8 is inconsistent", "No more data to read from Socket" (translated from dutch). When removing the value from the "error table name" property again, the mapping can be recreated again.
What am I doing wrong? Have I run into a bug?

Which database version are you using?
Also not sure when exactly the error occurs, when you deploy the map...or when you execute the map? Can you describe as simple a scenario for it to fail that you can?
I did find a bug 5942415 which was to do with this area..worth checking anyway.

DML Error Logging for underlying tables autocreated for dimensions

Hi,
I have problems with logging errors during mapping for underlying tables that are automatically generated for creating dimensions. I know that DML Error Logging is supposed to work only on tables, views and materialized views, and I have tried it out using a pure table in a mapping without any reference to a dimension and specifying the error table name for it. This works perfectly. The error rows were captured correctly in the error table and the correct rows were also loaded successfully to the target table.
However when it comes to mapping to a dimension, I have some issues with that. I specified the shadowtable name for the underlying table(right clicking on the table in design center and then choosing configure), and after deploying I did check that the error table/shadow table and also the target table were indeed created in the database.
The problem lies now in the mapping because I am actually mapping to a dimension and not the underlying table the dimension references to. It seems that the mapping did not manage to capture details of the error table for the underlying table that the dimension was referencing to and thus were unable to capture the errors. Only the corrected rows get loaded and there were no error messages during the loading that suggests that the incorrect rows were detected.
Would appreciate some assistance here.
Thanks!
WY

Hi
The DML error logging feature in 10gR2 and 11gR1 was restricted purely to tables, so the dimension operator did not support it. This is now supported in OWB 11gR2 (plus there is the orphan management functionality).

* the Error table name property is set for the operator (table/view/mv)
* the PL/SQL Generated Mode of the module that contains the mapping is set to 10gR2
and above or Default.
i was followed according to the instruction but i am not able to get desired output. can any one suggest me where i am wrong.
i am using set based PL/SQL mapping.

DML Error logging for Update statement

Hello,
I am facing a problem with regard to DML Error logging with Update statement .
oracle : 10.2
I am executing following DML update:
BEGIN
UPDATE
table_1 a
SET a.Exp_DATE =a.EFF_DATE
WHERE a.col_a1 != (SELECT b.colb1
                     FROM table_2 b
                     WHERE a.msisdn =b.msisdn )
LOG ERRORS INTO table_1_ERR REJECT LIMIT UNLIMITED;
END ;    I was expecting that "ORA-01427: single-row subquery returns more than one row" would be captured in LOG error table "table_1_err"
but instead I got run time error and whole dml was rolled back.
Please let me know whether this exception is not captured by DML error logging.
Thanks,
Abhishek

*Oracle logs the following errors during DML operations:** Column values that are too large.
* Constraint violations (NOT NULL, unique, referential, and check constraints).
* Errors raised during trigger execution.
* Errors resulting from type conversion between a column in a subquery and the corresponding column of the table.
* Partition mapping errors.

Limitation on DML error logging

Can someone please advise what is not supported by DML error logging which was introduced in Oracle 10g?
one Oracle document says "You cannot track errors in the error logging table for LONG, LOB, or object type columns".
One says only non-scalar columns, like datatime is not support.
Another one says it doesn't support nested table.
Anyone has a more complete list of limitation?
Thanks!

BULK INSERT into View w/ Instead Of Trigger - DML ERROR LOGGING Issue

Oracle 10.2.0.4
I cannot figure out why I cannot get bulk insert errors to aggregate and allow the insert to continue when bulk inserting into a view with an Instead of Trigger. Whether I use LOG ERRORS clause or I use SQL%BULK_EXCEPTIONS, the insert works until it hits the first exception and then exits.
Here's what I'm doing:
1. I'm bulk inserting into a view with an Instead of Trigger on it that performs the actual updating on the underlying table. This table is a child table with a foreign key constraint to a reference table containing the primary key. In the Instead of Trigger, it attempts to insert a record into the child table and I get the following exception: +5:37:55 ORA-02291: integrity constraint (FK_TEST_TABLE) violated - parent key not found+, which is expected, but the error should be logged in the table and the rest of the inserts should complete. Instead the bulk insert exits.
2. If I change this to bulk insert into the underlying table directly, it works, all errors get put into the error logging table and the insert completes all non-exception records.
Here's the "test" procedure I created to test my scenario:
View: V_TEST_TABLE
Underlying Table: TEST_TABLE
PROCEDURE BulkTest
IS
TYPE remDataType IS TABLE of v_TEST_TABLE%ROWTYPE INDEX BY BINARY_INTEGER;
varRemData remDataType;
begin
select /*+ DRIVING_SITE(r)*/ *
BULK COLLECT INTO varRemData
from TEST_TABLE@REMOTE_LINK
where effectiveday < to_date('06/16/2012 04','mm/dd/yyyy hh24')
and terminationday > to_date('06/14/2012 04','mm/dd/yyyy hh24');
BEGIN
FORALL idx IN varRemData.FIRST .. varRemData.LAST
INSERT INTO v_TEST_TABLE VALUES varRemData(idx) LOG ERRORS INTO dbcompare.ERR$_TEST_TABLE ('INSERT') REJECT LIMIT UNLIMITED;
EXCEPTION WHEN others THEN
DBMS_OUTPUT.put_line('ErrorCode: '||SQLCODE);
END;
COMMIT;
end;
I've reviewed Oracle's documentation on both DML logging tools and neither has any restrictions (at least that I can see) that would prevent this from working correctly.
Any help would be appreciated....
Thanks,
Steve

Thanks, obviously this is my first post, I'm desperate to figure out why this won't work....
This code I sent is only a test proc to try and troubleshoot the issue, the others with the debug statement is only to capture the insert failing and not aggregating the errors, that won't be in the real proc.....
Thanks,
Steve

OWB 10gR2 Does not support DML Error Logging

I've just had this confirmed by support.
So Oracle's key ETL tool does not support 10gR2s key ETL feature DML Logging.
So far set based loads on large volume databases you are going to find yourself being tripped over into row by row processing.
I find this staggering.
Has anyone else found this?

Oracle has come back to us saying that
"DML error logging feature is not supported for distributed DML."

Alternative to DML Error Logging

I am supposed to catch invalid records in error table with the ORA exception. I am using 10g. Using DML Error logging i cannot catch primary key violations. Using for loop it will be very slow because there are lots of records. How to catch invalid records with the ORA exception
Thanks

The DML error logging functionality is not invoked when:
Deferred constraints are violated.
Direct-path INSERT or MERGE operations raise unique constraint or index violations.
UPDATE or MERGE operations raise a unique constraint or index violation.

DML Error Logging

When I tried
EXECUTE DBMS_ERRLOG.CREATE_ERROR_LOG('table');
in Oracle Database XE, I got error: ORA-00900: invalid SQL statement.
Error Logging Table is a new feature for 10g. Does XE has this new feature?
Thanks for the help!

It works!!!
The issue only happens in Oracle SQL Developer and Oracle console opened in IE browser.
The issue also happens in SQL Command Line if using "begin" and "end" as the begining and the ending of the SQL statement
SQL> begin
2 EXECUTE DBMS_ERRLOG.CREATE_ERROR_LOG('MIGR_STOCK')
3 end;
4 /
EXECUTE DBMS_ERRLOG.CREATE_ERROR_LOG('MIGR_STOCK')
ERROR at line 2:

However it works well if only execute one line command
SQL> DROP TABLE ERR$_MIGR_STOCK CASCADE CONSTRAINTS PURGE;
Table dropped.
SQL> EXECUTE DBMS_ERRLOG.CREATE_ERROR_LOG('MIGR_STOCK');
PL/SQL procedure successfully completed.
Don't know why? But Thank you very much!!!
