This permits the execution of hardware online maintenance, which comprises the following tasks:
maintaining and evaluating the hardware error statistics file
execution of statistics and trace programs under the control of BS2000, in parallel to the user programs
Upon delivery, the privilege HARDWARE-MAINTENANCE is assigned to the user ID SERVICE. The security administrator can assign this privilege to any other user ID (except his/her own).
If the privilege HARDWARE-MAINTENANCE is assigned to a user ID other than SERVICE, the following must be noted:
for security reasons, user IDs with the privilege HARDWARE-MAINTENANCE are subject to special restrictions in BS2000 OSD/BC <= V10.0. In particular, the loading and execution of programs is not always permitted.
a user ID with the privilege HARDWARE-MAINTENANCE is only allowed to access files belonging to other IDs (e.g SERVICE) if the following applies:
if the file is protected by guards then access conditions which permit access to the privileged user ID must be defined in the guard’s access conditions.
if the file is not protected by guards but by a basic access control list (BACL) then this must permit access by the privileged user ID.
if the file is not protected by guards or by a BACL then USER-ACCESS=*SPECIAL must be set.
It must therefore be ensured that this user ID is allowed access to all files to which access is required for work purposes.
The hardware online maintenance privilege is referred to as HARDWARE-MAINTENANCE in commands and messages and as HWMAINT in macros.
