Flat Files as Targets

I am working on Oralce Warehouse Builder(9.2). I would like to extract data from Oracle Db(8.1.7.4) and then transform to Flat Files...Could any one help me out how to set target as Flat files. or Is it possible to do that? your help would be highly appreciated.
Thanks,
Srikanth.

Flat File as Target - MultiRecord Type

How do I write from Oracle into a Flat File as Target where the data in Flat file is a multirecord type. For ex. Sales Order header and Sales Order Line info.
I tried to do this by using a Joiner to the sales order header, line and items table and then mapping outgrp of joiner to the Flat file data with two record types in it. But when I generate and run this it could only create header records in out put file

Dear 396217,
As far as I am concerned you cannot really push out to a multi record structure without manual intervention.
There are a few things you can do: on the target (not sure whether that was already available in 9.0.3... but it definitely is in 9.0.4) you can set the flat file as a target to generate field names as headers. If that is what you want... then great.
The initial scenario: orders and order items in one model, is not supported. What you could do... is write a transformation to do this. Use calls to UTL_FILE to implement those and generate your own records. Primitive... but it works.
Alternatively, create 2 files and have a separate external process merge these. Not ideal; I realize that.

Flat file as targets in a mapping.

Hi All,
While reading on-line documentation in topic Define Mappings of oracle9i warehouse builder i came across following statement.
"A mapping can contain up to 50 flat files as targets, and it can also contain mix of flat files, relational objects and transformations."
Does this mean a flat file can be used as target in a mapping? I am in impression that only flat file can be used as source in a mapping.
Thanks in Advance.

Vidyanand

Hi Igor,
Some update on this, I managed to find steps to include flat file as target in a mapping.
Steps followed were as follows.
1> Created a File Module.
2> Imported a Text File with headings and no records.
3> Created a Warehouse Module.
4> Imported scott.dept table into the module.
5> Created a mapping, mapped scott.dept table to the text file.
6> Selected Configure option in the mapping. Set parameters Thefilename = the above file name and Access Specification).
7> Validated & Generated map, it looks fine with no errors.
8> Deployed & run the package.Deployment didn't show any errors however while running displays error ORA-01403: no data found.
Please note that the utl_file_dir parameter is set on oracle server and the utl_file_dir is mapped in windows NT explorer from machine.
Does anyone knows more about this error?
Thanks in Advance.

Load data from flat file to target table with scheduling in loader

Hi All,
I have requirement as follows.
I need to load the data to the target table on every Saturday. My source file consists of dataof several sates.For every week i have to load one particular state data to target table.
If first week I loaded AP data, then second week on Saturday karnatak, etc.
can u plz provide code also how can i schedule the data load with every saturday with different state column values automatically.
Thanks & Regards,
Sekhar

The best solution would be:
get the flat file to the Database server
define an External Table pointing to that flat file
insert into destination table(s) as select * from external_table
Loading only single state data each Saturday might mean troubles, but assuming there are valid reasons to do so, you could:
create a job with a p_state parameter executing insert into destination table(s) as select * from external_table where state = p_state
create a Scheduler chain where each member runs on next Saturday executing the same job with a different p_stateparameter

Flat file to target table map in 11G

Hi,
I am havin many problem with my 10G R1 map that have been migrated to 11G.
all that my 10G map has is mapping from flat file to stage table. It also had one constant operator. i am getting error coz of this constant that i am setting up in the map.
when i validate this constant variable i get error mess:

if you note 11G some how does not allow me to have constant operator in flat file maps. and the constant for PHONE_COUNTRY column is enclosed in double quotes insted of single quotes.[should be 'Asia' and not ''Asia'']
can any one tell me why this is heppening?...i also have problem with the READ BUFFER property. which in 10G used to be defulted to '4' but ignored which generating the .ctl but in 11G this property creates READ BUFFERS statement in .ctl....any help in this will be grt.

if you note 11G some how does not allow me to have constant operator in flat file maps. and the constant for >PHONE_COUNTRY column is enclosed in double quotes insted of single quotes.Hi
Please open the same mapping in 10g R2 its same .
It use Double code around the column name.
By the way execute the mapping and then check are you getting desired result.

How to use Flat files as targets

The root path of location LOC_FLAT_TGT must be specified as one of the file paths for the UTL_FILE_DIR parameter in the init.ora for the runtime instance. The root path of location LOC_FLAT_TGT must be a file path on the server.
Thanks in Advance,
Jash

Hi,
This is basically saying, either use the value of UTL_FILE_DIR of the runtime instance while registering your Target File Location
OR
ask your DBAs to change the UTL_FILE_DIR to the directory path where you want to place your files..........

Flat file to Target Table Mapping.

Hi All,
OWB Client 9.0.2.56.0
OWB Repository 9.0.2.0
WIN - NT 196 MB RAM.
I created a mapping which involved a fixed width text file
( Size of text file is 5 MB & number of columns around 28), applied some filter criteria & performed insert operation in a target table.
All seems to be fine, i could validate the mapping without errors & generate the mapping. I can save newly generated control file & uploaded the data into the target table using sqlldr. However it seems even after i selected Close command button in Generate Result window nothing happens, only way i can exit from this is by killing the session & this result in auto deletion of newly created mapping (Even though i commit the changes before selecting Close command button in Result Window).
Is this happening due to memory constraint ? ( I am aware that for OWB recommended RAM is around 256 MB.).
Just to add more i am experiencing this only for one specific mapping.
Thanks in Advance.
Regards,
Vidyanand

Hi,
The error while I was getting earlier was solved. I have placed the schema as "target.<tablename>" in the table operator counfiguration while configuring the mapping.
But now I am getting the error
SQL*Loader-350: Syntax error at line 22.
Expecting "(", found ".".
INTO TABLE "target.custfile_target"."CUSTFILE_TARGET".
Please suggest on how to proceed now as i am not able to find how and where i can correct such syntax error in OWB.
Regards.

SQL Server Source and Flat File Target in OWB

Hello All,
I have a question, is it possible to have SQL Server as Source and Flat File as Target without using any intermediate Oracle table(s).
like
SQL Server --> ETL Operators --> Flat file?
as i m getting errors in data type conversions here. but if i replace flat file with Oracle table it works fine. (though i have used some conversion functions for data types as well in Flat file loading but it is giving me errors)
Thanks in advance.
Tayyeb

Yes this should be fine. Are you using the gateway to access SQLServer or code template mappings? You need to track which columns are throwing the data type conversion errors.
Cheers

Flat file as source and target in owb-error

hi,
I want to run an interface with source as flat file and target as rdbms table.
The mapping got deployed with warnings.
And when i run the mapping i get the below error.
ORA-04063: package body "Schema.project_name" has errors
ORA-06508: PL/SQL: could not find program unit being called: "schema.project_name"
ORA-06512: at line 1

Hi
There's nothing wrong with your theory, however you might get a DB lock depending on the locking strategy of your RDBMS and it's current configuration.
Now, assuming that DB locking is your issue (get a DBA to check when the dataflow stalls), there are 2 solutions.
1, change the DB lock settings
2, take a copy of the target table in a new dataflow and use that as the source in the orginal dataflow.

Hi,
     NameA.addHeaderLine
Specify whether the text file will have a header line with column names. The following values are permitted:
■       0 u2013 No header line
■       1 u2013 Header line with column names from the XML document
■       2 u2013 As for 1, followed by a blank line
■       3 u2013 Header line is stored as NameA.headerLine in the configuration and is applied
■       4 u2013 As for 3, followed by a blank line
This specification is only permitted if exactly one structure is defined.

OWB FLAT FILE MAPPING NOT ABLE TO DEPLOY

Hi,
I've recently started studying data warehousing and exploring the Datawarehouse builder version 3i.
I've created a simple mapping from a csv file to database table ie my source is a flat file and target is a database table. The mapping gets validated successfully and the ctl scrip also gets generated. But the 'Deploy' and "Run' buttons on the "Transformations" tab of the "Generation Results" window are displabled(greyed out) and hence I cannot deploy the generated script.
Please do suggest the cause and solution for the same.
Regards,
Barkha

Many Thanks to Winfred Deering from Oracle who replied:
"This is the expected behavior for flat file mappings. You can register the tcl script with Oracle Enterprise Manager and run it from there. Also you can save the control file and execute via sql loader. "
Thanks and Regards,
Barkha

Classes for converting a flat file to XML

I've been asked to convert text in a flat file to an XML document. The XML document must conform to an XML schema. Currenlty, there is no requirement to store the resulting xml in the database.
Therefore my approach will be:
1. parse the flat file and store the contents in an array (the flat file and target xml is fairly simple in structure)
2. Transfer the contents of the array to the xml structure
3. validate the xml against the schema
I'm new to Java. Therefore, what classes should I be using to assist in step 2. Obvoiusly, I dont want to have to write my own implementation from scratch (i.e. a method to build an element, method to escape reserved characters etc).
Could you please suggest classes that cover both DOM and SAX API's.
I'm working with a 9.2.0.4 database and XDK.
Thanks

The Stylus Studio may be used to convert text file to XML.

Please help.

Dear All,
I have a problem with loading flat files to oracle tables using OWB 9.2
i created a map with my flat file as a source and my oracle table as a target,and i created a connector between the target location and the flat file location.And i deployed the connector and registered the flat file location using my PC information and the path of the files on my pc.
I generated the map and saved the .ctl file and deployed the map,and hence trying to load the ctl file using the sql loader as the following:
C:\Documents and Settings\CORAL 2000>sqlldr owb_rt_rep/owb_rt_rep@ofsa
control = D:\oracle2\ofsa\owb\codegen\BM_DEBIT_CARDS_DAT_MAP.ctl
---where owb_rt_rep is my runtime repository user.
I got the following error:
SQL*Loader-350: Syntax error at line 18.
Expecting "(", found ".".
INTO TABLE "{{TRG_LOC1.Schema}}"."BM_DEBIT_CARDS_DAT"
--where trg_loc1 is my target location and bm_debit_cards_dat is my target table.
I tried to grant from the target schema the privelages to the runtime user incase its the problem,but still it didn't work.
Any ideas??

Different formats of the flat file for the same target

In our deployment, we use plugin code to extract the csv files in the required format. The customers are on same version of datamart, but they are on different versions of source database - from 3.x to 4.5 depending on which version of application they are using. In 4.0, we introduced a new column email in the user table in the source database. Accordingly, plugin will add the field in the csv file. But not all the customers will get the upgraded version of plugin at the same time. So ETL code needs to decide which data flow to process depending on the format of the csv file to load data to the same target table. I made the email field in the target table nullable but it still expects the same format of the csv file with delimiter for null value.
Need help to achieve this. Can I read the structure of the flat file in DS or get the count of delimiters so that I can use a conditional to use different data flow based on the format of the flat files.
Can I make the email column in the flat file optional?
Thanks much in advance.

You can add an email column that maps to null in a query transform for the source that does not contain this column.
Or else you can define two different file formats that map to the same file. One with the column and one without

Issue with characterset setting in OWB flat file target

an OWB mapping reads from the database source and writes to flat file target in unix os but junk characters are displayed for non english characters in the target file . The database table contains french,spanish,german,arabic characters.The nls db parameter setting is AL32UTF8. The same setting has been applied to OWB target also but still junk values are appearing for non english characterset.different charactersets like al32utf8,utf8,utf18,us7ascii have been tried at owb target setting but nothing is wroking out to remove junk characters. Please suggest
