COBOL Copybook reverse-engineering allows you to retrieve a legacy file structure from its description contained in a COBOL Copybook file in Data Integrator.
To reverse-engineer a COBOL Copybook:
Create or open a file datastore that has a fixed format
Go to the column tab
Click the Reverse COBOL Copybook button
Fill in the following fields:
File: Location of the Copybook file
Character set: Copybook file charset
Description format (EBCDIC | ASCII): description (copybook) file format
Data format (EBCDIC | ASCII): data file format
Click OK
The columns described in the Copybook are reverse-engineered and appear in the column list.
Note: Columns for which data type is not declared in Oracle Data Integrator appear with no data type.
