Creating a z/OS File System Mapping file

About this task

You do not need a mapping file if you plan to use the LIST parameter when you run the code review application on z/OS®.

A z/OS File System Mapping file contains mappings that are exported from the z/OS File System Mapping view. A z/OS File System Mapping file is not required for running the z/OS code review application unless the data sets that you analyze have nondefault file system mappings.

At run time, the z/OS code review application checks the low-level qualifier of each data set that it processes. If it finds a match in the file system mappings, then it processes the data set. If not, then it skips the data set.

The default action is that the z/OS code review application searches the default file system mappings. If a z/OS File System Mapping file is specified, the application searches the mapping file rather than the default mappings.

Procedure

To create a z/OS File System Mapping file, follow these steps:

  1. Open the z/OS File System Mapping view by clicking Window (on Windows) or IBM® Developer for z/OS (on macOS) > Show View > Other > z/OS Project Views > z/OS File System Mapping.
  2. On the toolbar, which is in the upper-right corner of the view, click the down arrow and then click Export Mappings.
  3. Follow the steps in the wizard to export the custom rules and categories to an archive file with the file extension .zip.

Results

The z/OS File System Mapping file is created.
