Outbound Interface Process in Oracle

Outbound Interface process:
Outbound Interface will be used to extract the data from oracle Database tables into the flat files.
While developing the outbound Interface we will use UTL_File to Extract the data.

Inbound Interface will be used to upload the data from legacy system (Flat files) into Oracle Applications base tables.
While Developing the Inbound interface we will use SQL * loader to import the data into base tables.

UTL_FILE Package :
==================
This is One of the PL/SQL Package which will be used to transfer the data from table to files from files to tables But when we are working for file to table we will use SQl *Loader to transfer from table to file We have no alternative we have to use UTL_FILE.

We will use following three functions to generate the file.
1)Utl_File.fopen = To open (or) Create the file
2)Utl_File.Put_line = To Transfer the data into the File.
3)Utl_File.fclose = To close the File after Data transfer.

Outbound Interface Process:
=============================
1)Develop the PL/SQL Program (Either Procedure or Package)
2)Write the Cursor to retrieve the data from database tables.
3)Create file or Open the File by using UTL_File.fopen().
4)Open the Cursor
5)If any validations are there write the validations
6)Transfer the Data into File by using UTL_File.Put_Line().
7)Close the Cursor.
8)Close the File by using UTL_File.fclose();
9)Register the Procedure or Package as Concurrent Program and submit from SRS Window.

Example:

TYPE Select * from v$parameter where name like '%utl_file%'

COPY ANY PATH IN THE ABOVE QUERY RESULT FOR OUTBOUND FILE DESTINATION

WE WILL USE THIS PATH IN PROCEDURE

NOTE: ONLY ABOVE QUERY PATHS ARE SUITABLE FOR OUTBOUND FILES
