Issue/Introduction

What changes were made to 12.2 regarding USS?

Environment

Release: SLOPFC00200-12.2-NetMaster-File Transfer Management
Component:

Resolution

All NetMaster releases up to R12.1

•UNIX support was provided out of the NMSSI

       •UNIX=YES  parm

•Runs as a subtask under NMSSI USERID
•Hit limitations of running a UNIX environment under a subtask.
•Conflicted with other NMSSI API’s that were in-use.

New r12.2 UNIX support

•Creates a new address space using IEESYSAS underneath the NetMaster Region.

•Within the guidelines of defined security it allows that address space to build its own UNIX environment without having to constrain the main NetMaster task.
        •Creation of IEESYSAS is controlled by security, ensure IEESYSAS security definitions are properly done.

 

Multiple security implementations can be utilized

•USERID level security – UNIX commands run under the NetMaster USERID that issued the command
       •PASSTICKET approach
       •BPX.DAEMON approach
       •SUPERUSER – UID(0)
•REGION level security – all UNIX commands run under the REGION Userid
