Issue/Introduction

We are trying to mask a mainframe file having 5 separate record types within the same file. We have exported the file out of Mainframe (ISAM) on Unix. We are trying to mask using FDM on windows. Once the masking is done, we want to import the masked file back to Mainframe on Unix.

Could you please guide us on the masking approach?

Environment

Release : 4.8

Component : CA Test Data Manager

Resolution

What you are trying to do is not supported by FDM. You cannot use FDM in this manner. This is why the TDM Mainframe toolkit was developed.You must use the TDM Mainframe Toolkit (GTXMSKVS) for your scenario.

My understanding from Engineering is the ISAM file format isn't a typical ASCII file, and therefore can't be used by FDM. The ISAM file is an offshoot of a VSAM cluster file, and therefore you must use GTXMSKVS.

For more information regarding GTXMSKVS see:
