Pre-emption Control
Pre-emption control allows applications to give scheduling hints to the kernel to
prevent preemption for short periods of time. This can improve the performance of
some classes of applications such as database servers.
/proc File System and Watchpoints
The previous flat /proc file system has been restructured into a directory hierarchy
that contains additional subdirectories for state information and control functions. It
also provides a watchpoint facility to monitor access to, and modification of, data in
the process address space. The new /proc file structure provides complete binary
compatibility with the old /proc interface.
The adb(1) command has been modified to use the new /proc watchpoint facility.
It now provides data breakpoints to cause the subject processes to stop on access to
specified variables.
For more information, see the adb(1) man page.
Federated Naming Service (FNS)
FNS is now compliant with the X/Open XFN CAE definition. FNS has also been
enhanced to include support for Lightweight Directory Access Protocol (LDAP). It
also provides improved support for the files and NIS back ends.
For more information, see Federated Naming Service Programming Guide, Solaris
Naming Administration Guide, and Solaris Naming Setup and Configuration Guide.
Asynchronous I/O for Tape Drives
Asynchronous I/O support for tapes provides an interface to improve performance
on the high performance tape devices. With the ability to queue up to requests, this
feature significantly improves the I/O throughput.
Solaris Developer Kit (SDK)
The SDK software is now built into the Solaris environment and is no longer an
unbundled product. All the information a developer needs to produce applications
and graphics handlers for end-user Solaris runtime environments is now available in
the Solaris software.
