Important to software developers that develop
applications that extend the use of a Sun Cluster environment.
Using the new Remote Shared Memory API, developers can program
their applications to lower the latency for message passing over
high-speed cluster interconnects. Such cluster-aware applications
can significantly reduce the time that is required to respond to
events in a a clustered configuration. Developers must have Sun
Cluster 3.0 installed. And, they need expertise to modify existing
applications to exploit the new interface. The
librsm(3LIB) man pages and the section
(3RSM) "Section 3: Extended Library Funtions" man
pages include references to RSM.

DiskSuite has been enhanced to remove the
8-partition limit for physical disks and certain RAID devices. The
new soft-partition feature allows thousands of independently
configurable partitions to be created and managed. DiskSuite can be
found in the Early Access (EA) directory.

Enhancements have been made to the Dynamic
Reconfiguration (DR) feature to improve integration with
applications. Using the Reconfiguration Coordination Manager,
applications can now be notified about system events and take
appropriate action within an application.

Some devices, such as certain tape drives and
frame buffers, should not lose power when their drivers are
detached. A new interface, ddi_removing_power(9F),
checks if a device may lose power as a result of a suspend
operation. A new property,
no-involuntary-power-cycles, can be specified to
ensure that the device is not powered down unintentionally. For
more information about power management issues, see the
ddi_removing_power(9F) and
no-involuntary-power-cycles(9P) man pages.

The Java 2 SDK standard Edition (J2SE) version
1.3.1 increases performance significantly over the prior release,
J2SE 1.3.0 . For a list of enhancements included in J2SE 1.3.1, see
sun.com/solaris/ds/ds-j2se/ |

Solaris now supports energy saving features in
the Frame Buffer Power Management (FBPM) and Display Power
Management System (DPMS). This enhancement fulfills the U.S.
Government's Energy Star program requirements and only works on
Energy-Star compliant hardware.

CDE audio tools have traditionally operated in
a framework in which all supported audio devices support both play
and record. With the introduction of support for more audio device
types, some of which are play-only or record-only, functionality
was added to display details pertinent only to the specific device.
In this way, users are not faced with a confusing or misleading
interface. For further information, see the Solaris 8 Desktop User
Supplement.

The Solaris 8 Intel Architecture (IA) system
can now boot from a network connection. The IA system must support
PXE. On a system that supports PXE, enable the system to use PXE by
using the system's BIOS setup tool or the network adapter's
configuration setup tool. Thhe Solaris boot diskette is available
for the systems that do not support this feature.

Provides mechanisms with which user
applications can build low-latency, high bandwidth messaging in
order to directly access interconnect hardware, bypassing the
operating system. This feature requires SCI-PCI or WildCat
Interconnect in the Sun Cluster 3.0 environment to utilize.

Solaris Live Upgrade feature significantly
reduces the usual service outage associated with an operating
system upgrade or maintenance. Solaris Live Upgrade technology
enables Solaris 8, 7 and 2.6 systems to continue to run normally
while an administrator upgrades or does routine mainenance on the
inactive or duplicate boot environment with the the latest release
of Solaris or patches. When satisfied with the process, the
administrator simply reboots the system to run the latest or
updated operating environment. Additional features include:
- Solaris Live Upgrade 2.0 integration with Web Start Flash:
Provides enterprise customers with a reliable and rapid migration
solution.
- Management of multiple boot environments: Provides a powerful
boot environment framework to create, manage, and maintain multiple
boot environments on the same system.
- Management of patch updates.
- Fall Back Mechanism: Supports software migration and fallback
to previous active boot environments in case of failure with
activiation or reboot.

The Solaris 8 10/01 release includes the PPP
over Ethernet (PPPoE) addition to Solaris PPP 4.0. PPPoE enables
the user to "tunnel" a PPP session over an Ethernet. Networks with
PPPoE in place can support multiple users connecting to a provider
over a single DSL device. For further information, see the
pppd(1m), chat(1m), and
pppstats(1m) man page. For information on licensing
terms, please refer to the incorporated material found in the
following files on your system after you've installed Solaris 8 OE
10/01:

Stereo viewing provides desktop users the
ability to view data delivered from individual channels. This
improves averaging all channels and presenting the data to the user
as a single waveform. In addition, the audio user gains control
over more recording parameters through the Record interface, and
can see a description of the audio file format on the desktop. For
further information, see the Solaris Common Desktop Environment:
User's Guide."

The USB technology and the USB audio support
in Solaris provide a low-cost way to add keyboards, mouse devices,
printers, and audio devices to a system. Support of USB Audio
devices that are USB Audio 1.0 compliant has been integrated for
both SPARC and Intel Architecture platforms. Recommended devices
are listed on www.sun.com/io. The USB Audio
driver is based on the new audio mixer(7I)
architecture. For further information, see the USB Administration
Guide. Solaris system administrators who intend to administer new
Sun hardware with USB support should review this book to become
familiar with the USB technology and features. |
