Usage of Error Table in OWB mapping

WE uses ERROR tables to take care of defective items in a maping. We want the rows in the error-table to remain and acumulate for each loading. That is, we do not want to truncate between running the mapping. We have:
Truncate table error = NO
Roll-up errors = NO
But the table is truncated between each load anyway.
Does anyone have any experience of how to make the table not to truncated?
We are using OWB 11.2.0.1
/John

Hi John
This looks to be fixed in the 11.2.0.2 OWB patch.
The bug is 9661088, otherwise you'd have to move/process the errors before re-run.

How to generate Error Table in OWB

Hi experts
I want to know about the rejected records. So
1. Should I create Error Table for that.?
2. Error table and shadow table are same thing..?
3. What are the steps to create error table.
Thanks in advance

hi all,
i have deployed my owb mapping in oracle. Now i want to execute this from the sql prompt. the foolowing error is giving when i try to run.

You need to split your data and create (at least 5) worksheet targets.
For example if you have a ROW_NUMBER column you can use for instance a
Conditional Split for something like:
ROW_NUMBER % 5 == 0 for Case 1 (excel 1)
ROW_NUMBER % 5 == 1 for Case 2 (excel 2)
ROW_NUMBER % 5 == 2 for Case 3 (excel 3)
ROW_NUMBER % 5 == 3 for Case 4 (excel 4)
ROW_NUMBER % 5 == 4 for Case 5 (excel 5)

Error while runinning OWB map.

Hi all,
I have installed OWB 10G. I am trying to run a simple map to load data from EMP table scott schema to another table(emp_test) in test_tgt schema. No transformations or expressions used. But at the time of deploying I get following error.
ORA-06550: line 83, column 24:

Any idea why am I getting this & how to correct this.
Thanks,

I hope that you are not in OWB10gR2.
Have you configured the runtime repositories as well as the target schema. when it's not clearly configured thats' the only possibel way to not able to deploy or exec any tasks.
Make sure the credentials, which your passing into Runtime Repository Connection is valid and accurate with Runtime access user and Runtime Repository Owner....I guess this will help you to get some areas to find out ...
Or you can create another on Runtime repository connection...

How to use error table in mapping level?

Hi all
Any one please tell me how to use error table in mapping level or how to handle the errors in mapping.
I am creating one error table in oracle but i dont know how to use it in mapping.
Thanks in advance.
Kumar

Hi Kumar,
You need to use Error Table along with the Data Rule .
Error tables are used with Logical error handlers (Data Rules). Detailed description on using data rules is explained in the following document
http://www.oracle.com/technology/products/warehouse/pdf/OWB10gR2_ETLandBusinessRules.pdf
In a nut shell usage of error tables is as follows.
1. Create a data rule associate it with a table (Target table or table in which you load data).
2. Use the table in a mapping as target table.
3. Deploy the table and mapping.
Now in the target schema one more table will be created with the name <target table name>_ERR. When a mapping is executed the data which violates the data rule gets into this error table.
The following has to be done to have error table name of customers choice.
1. Right click on the table and click configure.
2. Give the table name in "shadow table name" section.
3. Deploy the table.
4. Use this table in a mapping. Now in the mapping on this table properties in "Error Table Name" section the name of the table specified in "shadow table name" will be populated.
Thanks,
Sutirtha

OWB 10.2.0.1 - Error Table

Hi All,
how can I use successfully the Error Table in a Mapping ? I have created 2 table (t_source [col_1 varchar2(10)] and t_target [col_2 varchar2(5)] ). I have configured mapping as rowbased and created with DBMS_ERRLOG.CREATE_ERROR_LOG one error table for each table.
But when i run mpaing (who discards every records ) i obtein empty error table ?!!
What can i do ?
Thanks,

Hi,
I have not tried to implement what has been said in the link, this link I had got from one of the replies in this forum.
One more approach you can try
For each of the object in OWB you can create data rules. There is a set of built-in data rules and also you can create your own set of data rules.
Once you have created these data rules on the fields of the table, you can deploy this table into your target schema. In the database, an error table is created for the table object.
Now when you use this table as a target in a mapping, click over the target table operator you will find the data rules node. Expand the node corresponding to the data rules for which you want error logging and then select 'MOVE TO ERROR' as Rule action.
Deploy the target table object and the mapping and execute it. Hopefully the rejections due to rule violations should get logged into error table, if you have set the Rule Action appropriately.

How do we use Data rules/error table for source validation?

How do we use Data rules/error table for source validation?
We are using OWB repository 10.2.0.3.0 and OWB client 10.2.0.3.33. The Oracle version is 10 G (10.2.0.3.0). OWB is installed on Linux.
I reviewed the posting
Re: Using Data Rules
Thanks for this forum.
I want to apply data rules to source table/view and rule violated rows should go to defined error table. Here is an example.
Table ProjectA
Pro_ID Number(10)
Project_name Varchar(50)
Pro_date Date
As per above posting, I created the table in object editor, created the data rule
NAME_NOT_NULL (ie project name not null). I specified the shadow table name as ProjectA_ERR
In mapping editor, I have projectA as source. I did not find error table name and defined data rules in table properties. It is not showing up the ERR group in source table
How do we bring the defined data rules and error table into mapping?
Are there any additional steps/process?
Any idea ?
Thanks in advance.
RI

Hi,
Thanks for your reply/pointer. I reviewed the blog. It is interesting.
What is the version of OWB used in this blog?
After defining data rule/shadow table, I deployed the table via CC. It created a error table and created the all the source coulmns in alphabatical order. If I have the primary key as 1st coulmn (which does not start with 'A') in my source, it will apprear middle of of columns in error table.
How do we prevent/workaround this?
If I have source(view) in sch A, how do we create Error table in Sch B for source(view)?
Is it feasible?
I brought the error table details in mapping. Configured the data rules/error tables.
If I picked up 'MOVE TO ERROR' option, I am getting "VLD-2802 Missing delete matching criteria in table. the condition is needed because the operator contain at least one data rule with a MOVE TO ERROR action"
On condition Loading - I have 'All constraints' for matching criteria.
I changed to "no constraints' still I get the above error.
If I change to 'REPORT' option instead of 'MOVE TO ERROR' option, error goes off.
Any idea?
Thanks in advance.

There are columns for data rule errors (logical errors) and DML errors (physical errors), I think you probably have data rules on the table..?
To process DML errors you will have to add the error table into a map you may have to reverse engineer it). The error group behavior is only available for processing errors from tables with data rules. Ensure your table operator is synchronized with your design table.

Shadow tables in OWB

hi,
If somebody got their hands on to the OWB Paris edition, can please throw some light on to the usage of Shadow Tables in OWB. Apparently, External Tables / Tables / Dimensions can be configured for the Shadow Table. I am just wondering how this can be used.
thanks
Mahesh

Hi
Prior to OWB 10.2.0.3 you can use the DML error logging features only for the mappings which runs
in ROW based mode.
But from OWB 10.2.0.3 onwards DML error logging features can be used for SET based mappings also.

Mapping aborts instead of records getting audited in error tables

We have several instances when a mapping encounters an invalid number error (source is non-numeric and target is numeric) and the mapping aborts with a "Invalid number" error, instead of the error being logged in the wb_rt_error* tables, and the mapping continuing. The max number of errors is set to 10,000 or something, so that is not an issue. In other instances, it does continue with warning as expected.
I can't seem to find a pattern with this. Can someone tell me why OWB behaves like this? Is there an explaination to this? We really don't want our mappings killed by bad source data. We sould like OWB to complain, log the error, and continue.
Please help.
-Whiskeylover

It sounds as though there is some specific type of data error which is occurring occassionally, and which OWB is not handling properly. As you point out, sometimes OWB does log and move on - sometimes it doesn't. The hard part is going to be figuring out what the exact data is that is causing the problem and resolving it.
On the next day when this happens, in the prod environment run something like:
declare
   cursor get_vals is
     select the_problem_field from the_source_table;
   function validate_field (invar in varchar2)
   return 0
   is
     testnum number;
   begin
     testnum := to_number(invar);
   exception
      when others then return 1;
   end;
begin
    for source_record in get_vals
    loop
       if validate_field(source_record.the_problem_field) = 1 then
           dbms_output.put_line(source_record.the_problem_field);
       end if;
    end;
end;
/This will give you the list of values which would fail the to_number, and you can try looking for anything extraordinary, or use it as a test sample to run through another mapping.
OH!!!! Wait!
Just had a thought.
If the query that is generating the data for the query is doing any formatting, then it could be the cursor that is failing and not the insert. In that case the cursor fails and exits as it cannot continue which would result in the circumstance you are describing. The error audit counting only works if the problem is at the insert portion of the code - not the select.
Open the mapping package body and pull the cursor out. If there is a to_number() or other function being applied against the source field then this almost certainly your problem.
You would be able to test this with a simple query by running a select with that function against the source table to see if it errors.
Case in point:
assume a varchar field that you are converting to date. You have desinged the mapping to use a to_Date() function with a format mask according to what should be in the field: e.g. to_date(the_field, 'yyyyymmdd'), and there is a singe record with the value '2009081111'. The select fails and will not process subsequent rows.
I would bet that this sort of thing is your issue.
Oh, and this error could be coming from any of the fields if you are getting a non-specific error - not neccessarily the field that you think is the problem.

Mike

OWB error table is not working?

Dear Oracle Experts,
I new to oracle OWB.
Platform Oracle 11gr2 in centos linux
i have created a new mapping which transfers the data between two schemas.when I deploy i didnt face any errors and when i run the mapping it shows log
ORA-00001 unique constraint (RAHS2MIG1.PK_OBJECT) VOILATED.
IS it possible to record this message in Error table? Please if any one know how to record the error in error table.
I can only able to edit dml error table name box in property inspector but i cannot able to edit error table name.
Also
I have created the error table with the sql
SQL> connect rahs2mig1/rahs2mig1
Connected.
begin
dbms_errlog.create_error_log('migrationinfo','ERROR$_MIG') ;
end;
PL/SQL procedure successfully completed.
I have created the table ERROR$_MIG for the target schema object migrationinfo.After clicking the start option in the mapping.
ORA-00001 unique constraint (RAHS2MIG1.PK_OBJECT) VOILATED. error shows only in the log.
No errors record in the ERROR$_MIG table.
Please advise.
Thanks in Advance
Regards,
Vijay

Vijay,
IT isn't enough to define the error table at the DB level. You must also inform the mapping to generate code to utilize that error table. If you check the properties on the table object in the mapping you will find that there is an ERROR TABLE NAME property that you need to set to the name of the error table.
Also note that the ORACLE syntax to put errors into the error table requires that the mapping be doing set-based processing, so check and make sure that you are indeed generating and running in set-based mode.
Cheers,
Mike

OWB Error handling through error tables

I have a mapping, which i want to implement error handling through error table, the table is created (error) and i have supplied it in the error table propertis in the target table. But i have tried testing if this is working by changing the data type of one column in my target database, but the whole mapping is failing to run with no error rerded in the error table. And i tried testing the this through sql and suprisingly the errors are being captured. How do i get the whole mapping to run and record the errors if any in the error table without it failing.

When you say 'the whole mapping is failing to run' what do you mean? Can you deploy the mapping? If not what is the error? When you run the mapping what happens?
If you look at the DML statement (the INSERT, MERGE or whatever) generated by OWB does it include the LOG ERRORS INTO statement in it?
There is a blog post below for OWB 11gR2;
http://blogs.oracle.com/warehousebuilder/entry/owb_11gr2_dml_error_logging
And an older one here which was based on OWB 10gR2

Does "Target table" and "Error Table" need to be in same DB as OWB's?

We get the following error ORA-00600: internal error code, arguments: [opixrb-3], [1036], ORA-01036: illegal variable name/number at the time of OWB execution
OWB seems to successfully log the errors rows in the error table when a) target table and it’s b) error table are in the same database as OWB’s but throws ORA-01036 error when they are in a remote database from OWB's
Any one has any information about this please...? It will be of great help
Edited by: ghiyer on Jul 20, 2009 8:42 AM

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

this table i have to include in all mappings and i have to load the errors in this table.please guide me
how to include this table and load the errors.if you have any code please send me.

end loop;
commit;
exception
     when others then
     dbms_output.put_line('Error:     '||SQLErrm);

You will get more than this and/or if you have just simple plan than this , would you mind to just let us know...
