Also, for sequential and VSAM data sources on z/OS, the utility can find record ID fields. This feature is useful if the COBOL copybook includes REDEFINE statements or multiple 01-level records and includes one or more record ID fields. The utility reads the COBOL copybook and the data files that you specify in the control file and finds likely RID fields and the data values that they contain. For each record layout that matches all of the data records that have a given RID value, the utility creates a table and a record in the data map and assigns a data value to the RID field.

To run the utility, use the infacmd pwx createdatamaps command. The Informatica services or the Informatica Client must be installed on the Windows machine on which you run the command.

You can create multiple data maps per run, but they must all be of the same data source type.

Use the createdatamaps utility to create new data maps only. Do not use the utility to modify data maps that are already in use.
