How to Extract data to a Flat File?

Question

Hello,
Im using OWB 10g and Oracle 9.2 version of database. I want to know the complete steps of creating the flat file as my target module. I need to extract the data (source) from the oracle tables and load it into the flat files. Pls let me know your suggestions. Pls note except the flat files, I do not have any oracle tables as my targets.
Thanks,
Kishan

Hi, here's an excerpt from some notes I wrote a few months ago, they shpoud be clear enough.
0) the file will be created on the server using the utl_file package. So the path where the file will be created must be added to the utl_file_dir Oracle Server parameter. Request your DBA to complete this step.
-In OWB client:
1) create a file location (or use existing one) under "Files/Locations" in project tree
2) create a new Flat File module (or use existing one) under "Files" ; associate it with the desired location (not really necessary)
3) create a new mapping in an Oracle module
4) add to mapping a table operator bound to the table to dump
5) add to mapping un unbound Flat File (FF) Operator, give it a meaningful name
6) drag the desired attributes from table to FF Operator. This will instruct OWB to feed the file with comma-separated values from the source table using the utl_file package. Be careful to format attributes accordingly to the format you want.
7) reconcile outbound the FF Operator, creating a new flat file in the module created during step 2
8) close mapping, right-click on it an from menu "Configure..."->"Sources&Targets"-><YOURTARGETFILE>, specify the desired output location and the output file name
9) Open deployment manager and connect to runtime rep. If the FF location is new, register it by right-clicking+menu "Register" and specify parameters: operating system user/passawrd of the DB server, host and path where the file will be stored (must be the same added to utl_file_dir). ATTENTION: path info is stored in the generated mapping so be sure to redeploy mappings if changes occur
10) deploy mapping, test execution
11) OPTIONAL you can specify a different delimiter (TAB,etc) for the target file directly in its editor. But be careful then to reconcile inbound the FF op in the mapping before deploying.
