Specifying scrambling options

Scrambling data allows you to create test data based on production (or "live") data, but with the ability to change the values of certain fields.

Scrambling can be performed by running the FM/IMS extract utility and selecting the scramble option either from the panel or using the SCRAMBLE=YES keyword for existing batch jobs. The fields in the templates associated with the extracted databases that have scrambling attributes set will be scrambled accordingly.

To mark a field for scrambling, set the scrambling options for that field in the template. You can specify or change scrambling options on the Field Attributes panel. This panel comes in two versions: one for alphanumeric fields and the other for numeric fields.
