Unix System Services


For z/OS Releases

Description
The Unix System Services (USS) service assists the user in configuring the USS run-time options of the z/OS system. This service provides refresh and customization. After a refresh during a first time customization a wizard checks if all necessary requirements are fullfilled to work with USS. All further customizations will launch a properties dialog, which enables the user to customize the settings in the BPXPRMxx parmlib member. In addition users can update/create their File System configuration. New File Types and File Systems can be defined. On request of the user a newly added HFS file system will be allocated and added to the BPXPRMxx parmlib member.


Policies Supplied
None.
