2 Operating System
The G06.28 RVU contains these changes for the HP NonStop operating system:
•
Kernel Subsystem
•
OSS Security APIs
•
POSIX Threads
Kernel Subsystem
A new feature is added to the existing functionality of configuring and managing
generic processes through Subsystem Control Facility (SCF). SCF now supports
ASSIGN, PARAM, and DEFINE values.
You can use the SCF ADD PROCESS command to add ASSIGN, PARAM, and
DEFINE values to a generic process. Also, you can use SCF commands such as
ALTER PROCESS, INFO PROCESS, and DELETE PROCESS, respectively, to alter,
view, and delete the ASSIGN, PARAM, and DEFINE values for a generic process. This
feature is similar to the existing ASSIGN, PARAM, and DEFINE functionality in TACL.
For details, see the SCF Reference Manual for the Kernel Subsystem.
OSS Security APIs
Functions are added to the HP NonStop Open System Services (OSS) file system
(T8620) to change the owner or access permissions for a file when the named file is a
symbolic link:
•
lchmod(2)
•
lchown(2)
Some functions are changed and new functions are added to the OSS file system
(T8620) to change the owner or access permissions for a file specified by a file
descriptor:
•
fchmod(2)
•
fchown(2)
Changes to the effective user ID or the effective group ID cause appropriate behavior
across processors within a server and among servers. Safeguard auditing also tracks
the changes. For detailed information, see the OSS System Calls Reference Manual.
Fallback
If you fall back, you cannot use the new functions and must recode applications to
remove them.
