Networking Enhancements

SPARC: TCP Multidata Transmit

Multidata transmit (MDT) enables the network stack to send more than one packet at one time to the network device driver during transmission. Enabling this feature reduces the per-packet processing costs by improving the host CPU utilization or network throughput.

The multidata transmit feature is only effective for device drivers that support this feature.

The following parameter must be enabled in the /etc/system file to use the MDT parameter:

set ip:ip_use_dl_cap = 0x1

MDT is disabled by default. The TCP/IP stack can be instructed to enable MDT as follows:

# ndd -set /dev/ip ip_multidata_outbound 1

Review the following cautions before enabling MDT:

For more information, see the Solaris Tunable Parameters Reference Manual and the ip(7P) man page.

Sun ONE Message Queue

The Solaris operating environment now supports Java Messaging Service (JMS) applications. This Solaris release uses Sun ONE Message Queue (formerly iPlanetTM Message Queue for Java) as a JMS provider.

Note –

The Sun ONE Message Queue is a new feature for the SPARC platform in the Solaris 9 12/02 Update release. In the Solaris 9 8/03 Update release, the Sun ONE Message Queue is also available for x86 platforms.

JMS messaging enables applications and application components to exchange messages asynchronously and reliably. Processes that run on different platforms and different operating systems can connect to a common message service to exchange information.

In this Solaris release, Sun ONE Message Queue, Platform Edition provides a full implementation of the JMS specification. The message queue provides additional features such as the following:

For further information, see the Sun ONE Message Queue 3.0.1 Administrator's Guide and the Sun ONE Message Queue 3.0.1 Developer's Guide. For information about Sun ONE Message Queue editions and features, see also the following Web site:


http://www.sun.com/software/products/message_queue/home_message_queue.html

SPARC: Sun ONE Application Server Integration

Sun ONE Application Server 7, Platform Edition (formerly iPlanet Application Server) is integrated in the Solaris operating environment. The Platform Edition of the Application Server provides the foundation for enterprise-class application services and web services. The server provides a high-performance, small-footprint JavaTM 2 Platform, Enterprise Edition (J2EETM). J2EE enables the development, deployment, and management of enterprise applications and web services to a broad range of servers, clients, and devices.

The Sun ONE Application Server provides application portability and fast time to market for new Java and Extensible Markup Language (XML) applications with J2EE 1.3 platform compatibility. The Application Server enables developers to build applications that are based on JavaServer PagesTM (JSPTM), Java Servlet, and Enterprise JavaBeansTM (EJBTM) technology. This technology supports a broad range of business requirements from small departmental applications to enterprise-scale, mission-critical services.

Some of the main feature highlights include the following:

The following name changes have been made:

For further information, see the Sun ONE Application Server 7 Collection Update 1 (Solaris Edition). Further information about this collection is available at New and Revised Documentation in the Solaris 9 8/03 Release. See also http://wwws.sun.com/software/products/appsrvr/home_appsrvr.html.

For specific licensing terms, refer to the binary code license.

Internet Protocol Version 6 (IPv6) 6to4 Router

IPv6 networks can now transfer packets over Internet Protocol Version 4 (IPv4) networks by configuring one or more routers to support a 6to4 tunnel. System administrators can use 6to4 tunnels as a transitional method for migrating their networks from IPv4 to IPv6. This feature implements RFCs 3056 and 3068.

For further information on IPv6, see the IPv6 Administration Guide.

Packet Tunneling Over IPv6

This feature enables tunneling over IPv6 for both IPv4 over IPv6 tunnels and IPv6 over IPv6 tunnels. IPv4 packets or IPv6 packets can be encapsulated in IPv6 packets.

For more information, see the IPv6 Adminisration Guide.

Hosting Multiple Web Sites on a Single Solaris Machine

The Solaris Network Cache and Accelerator (NCA) kernel module now supports multiple instances of a web server. This support enables you to use a Solaris machine to perform Internet protocol (IP) address-based virtual web hosting. The Solaris software uses a single configuration file, /etc/nca/ncaport.conf, to map NCA sockets to IP addresses.

For further information, see the ncaport.conf(4) man page.

IP Quality of Service

IP Quality of Service (IPQoS) is a new feature in the Solaris operating environment. IPQoS enables system administrators to provide different levels of network service to customers and to critical applications. By using IPQoS, the administrator can set up service-level agreements. These agreements provide an Internet service provider's (ISP) clients with varying levels of service that are based on a price structure. A company could also use IPQoS to prioritize among applications so that critical applications get a higher quality of service than less critical applications.

For further information, see the IPQoS Administration Guide.

User Selector for Internet Protocol Quality of Service (IPQoS)

The Solaris IPQoS feature now includes the user selector, which supplements the existing uid selector. The user selector enables you to specify a user name or userID as criteria in a filter clause in the ipqosconf file. Previously, the uid selector only accepted a userID as a value. The following filter clause from an ipqosconf file shows the user selector:


filter {
              name myhost
              user root
}

For information about filters and selectors, refer to the IPQoS Administration Guide and the ipqosconf(1M) man page.

Routing Information Protocol Version 2 (RIPv2)

Solaris system software now supports Routing Information Protocol Version 2 (RIPv2).

RIPv2 adds Classless Inter-Domain Routing (CIDR) and Variable-Length Subnet Mask (VLSM) extensions to the RIPv1 protocol. Message Digest 5 (MD5) extensions protect routers against intentional misdirection by malicious users. The new in.routed implementation also includes a built-in Internet Control Message Protocol (ICMP) Router Discovery (RFC 1256) mechanism.

RIPv2 supports multicast, if the point-to-point links are enabled with multicast. RIPv2 also supports unicast. If you configure a broadcast address by using the /etc/gateways file, then RIPv2 supports broadcast.

For information on how to configure RIPv2, see the in.rdisc(1M), in.routed(1M), and gateways(4) man pages.

Installation Enhancements

Solaris Live Upgrade 2.1

Solaris Live Upgrade provides a method of upgrading a system while the system continues to operate. While your current boot environment is running, you can duplicate the boot environment, then upgrade the duplicate. Or, rather than upgrading, you can install a Solaris Flash archive on a boot environment. The original system configuration remains fully functional and unaffected by the upgrade or installation of an archive. When you are ready, you can activate the new boot environment by rebooting the system. If a failure occurs, you have a safety net. You can quickly revert to the original boot environment with a simple reboot. Thus, you eliminate the normal downtime of the test and evaluation process.

New features in Solaris Live Upgrade 2.1 provide the following new functionality.

For further information, see the Solaris 9 Installation Guide.

Solaris Flash Archives

The Solaris Flash installation feature enables you to use a single reference installation of the Solaris operating environment on a system, which is called the master system. Then, you can replicate that installation on a number of systems, which are called clone systems. The installation is an initial installation that overwrites all files on the clone system.

In the Solaris 9 4/03 Update release, the Solaris Flash installation feature provides new enhancements for differential archives and configuration scripts.

For further information, see the Solaris 9 Installation Guide. This guide also includes information on how to use Solaris Live Upgrade to install a differential archive.

In the Solaris 9 12/02 Update release, you can customize contents in a Solaris Flash Archive. The flarcreate command is used to create a Solaris Flash archive. This command has been updated with new options that increase your flexibility to define archive contents when creating an archive. You now can exclude more than one file or directory. From an excluded directory, you can add back a subdirectory or file. This feature is useful when you want to exclude large data files that you do not want cloned.

For information on how to use these options, see the Solaris 9 Installation Guide.

Note –

In the Solaris 9 Update releases, note the following name change:

Command-Line Interface Enhancements to the Solaris Product Registry

The prodreg command has been updated to include functionality that is similar to the Solaris Product Registry graphical user interface. You can now use the following prodreg subcommands on the command line or in administration scripts to perform a variety of tasks.

For more information, see the prodreg(1M) man page and the System Administration Guide: Basic Administration.

Support for LDAP Version 2 Profiles

The Solaris installation programs now support LDAP Version 2 profiles. These profiles enable you to configure your system to use a proxy credential level. During the Solaris Web Start or suninstall programs, you can specify the LDAP proxy-bind distinguished name and proxy-bind password. With any installation method, you can preconfigure LDAP before installation by using the proxy_dn and proxy_password keywords in the sysidcfg file.

For information, see the Solaris 9 Installation Guide.

Web Browser Enhancements

Netscape 7.0 for the Solaris Operating Environment

The NetscapeTM 7.0 cross-platform browser integrates features for navigating the Web, communicating with colleagues, participating in discussion groups, and creating dynamic Web pages. Netscape 7.0 provides the following:

Netscape 7.0 highlights include the following:

For more information on Netscape 7.0, see the following Web site:

http://www.sun.com/software/solaris/netscape

Netscape 6.2.3 for the Solaris Operating Environment

In the Solaris 9 12/02 Update release, NetscapeTM 6.2.3 is included in the Solaris operating environment. In the Solaris 9 4/03 Update release, Netscape 7.0 is provided. See the “Netscape 7.0 for the Solaris Operating Environment” description.

Security Enhancements

Auditing Enhancements

Enhancements to the audit features in this Solaris release reduce noise in the trail, and enable administrators to use XML scripting to parse the trail. These enhancements include the following:

For further information, see the System Administration Guide: Security Services.

Smart Card Terminal Interfaces

Solaris smart card interfaces are a set of public interfaces for Smart Card Terminals. See Smart Card Terminal Interfaces.

Internet Key Exchange (IKE) Hardware Acceleration

Public-key operations in IKE can be accelerated by a SunTM Crypto Accelerator 1000 card. The operations are offloaded to the card. The offloading accelerates encryption and reduces demands on operating system resources.

For information about IKE, see the IPsec and IKE Administration Guide.

Enhanced crypt() Function

Password encryption protects passwords from being read by intruders. Three strong password encryption modules are now available in the software:

For information on how to protect your user passwords with these new encryption modules, see the System Administration Guide: Security Services. For information on the strength of the modules, see the crypt_bsdbf(5), crypt_bsdmd5(5), and crypt_sunmd5(5) man pages.

Password Management Feature in pam_ldap

The pam_ldap password management feature strengthens the overall security of the LDAP Naming Service when used in conjunction with the Sun ONE Directory Server (formerly iPlanet Directory Server). Specifically, the password management feature does the following:

For further information on Solaris naming and directory services, see the System Administration Guide: Naming and Directory Services (DNS, NIS, and LDAP). For information about Solaris security features, see the System Administration Guide: Security Services.

Pluggable Authentication Module (PAM) Enhancement

The PAM framework was expanded by including a new control flag. The new control flag provides the ability to skip additional stack processing. This skipping is enabled if the current service module is successful and if no failure occurred on the previous mandatory modules.

For more information about this change, see the System Administration Guide: Security Services.

File System Enhancements

SPARC: Multiterabyte UFS File Systems

This Solaris release provides support for multiterabyte UFS file systems on systems that run a 64-bit Solaris kernel. Previously, UFS file systems were limited to approximately 1 terabyte (Tbyte) on both 64-bit and 32-bit systems. All UFS file system commands and utilities have been updated to support multiterabyte UFS file systems.

You can initially create a UFS file system that is less than 1 Tbyte. You can specify that the file system can eventually be grown to a multiterabyte file system by using the newfs -T command. This option sets the inode and fragment density to scale appropriately for a multiterabyte file system.

Support for a multiterabyte UFS file system assumes the availability of multiterabyte LUNs, provided as Solaris Volume Manager or Veritas VxVM volumes, or as physical disks that are greater than 1 Tbyte.

Features of multiterabyte UFS file systems include the following:

Limitations of multiterabyte UFS file systems include the following:

For more information, see the System Administration Guide: Basic Administration.

SPARC: Multiterabyte Volume Support With EFI Disk Labels

This Solaris release provides support for disks that are larger than 1 terabyte (Tbyte) on systems that run a 64-bit Solaris kernel.

The Extensible Firmware Interface (EFI) label provides support for physical disks and virtual disk volumes. The UFS file system is compatible with the EFI disk label, but you cannot create a UFS file system that is greater than 1 Tbyte. This release also includes updated disk utilities for managing disks that are greater than 1 Tbyte.

The EFI disk label differs from the VTOC disk label in the following ways:

For more information on using the EFI disk label, see the System Administration Guide: Basic Administration. This guide contains important information and restrictions that apply to using the EFI disk label with existing software products.

The Solaris Volume Manager software can also be used to manage disks greater than 1 Tbyte in this Solaris release. See SPARC: Multiterabyte Volume Support in Solaris Volume Manager.

System Performance Enhancements

UFS Logging Performance Enhancements

UFS logging enables faster system reboots. Because the file system transactions are already stored, checking the file system is not required if the file system is already consistent.

In addition, the performance of UFS logging improves or exceeds the level of performance of nonlogging file systems in this Solaris release. Results of the Standard Performance Evaluation Corporation system file server (SPECsfs) benchmark show that the performance of NFS-mounted file systems that have logging enabled equals the level of non-UFS logging performance. In some I/O-bound configurations, logging UFS file systems exceed the performance of nonlogging UFS file systems by approximately 25 percent. In other tests, performance of logging UFS file systems is 12 times better than the performance of nonlogging UFS file systems.

For information on how to enable logging on a UFS file system, see the System Administration Guide: Basic Administration or the mount_ufs(1M) man page.

SPARC: Memory Placement Optimization (MPO)

The Solaris dispatcher and the virtual memory subsystem are enhanced to optimize the time that is required for an application to access memory. This enhancement can automatically improve the performance of many applications. This feature is currently implemented to support specific platforms such as the Sun FireTM 3800–6800, the Sun Fire 12K, and the Sun Fire 15K.

A technical white paper about Solaris Memory Placement Optimization and Sun Servers is available at the following Web site:

http://www.sun.com/servers/wp/docs/mpo_v7_CUSTOMER.pdf

SPARC: Dynamic Intimate Shared Memory (DISM) Large-Page Support

Large-page support is now provided for Dynamic Intimate Shared Memory (DISM). This large-page support can increase the performance of applications that are capable of dynamically adjusting shared memory sizes.

For further information on DISM, see System Performance Enhancements.

System Administration Tools

BIND 8.3.3

The version of BIND that is integrated in the Solaris 9 8/03 Update release is BIND version 8.3.3.

SPARC: Multiterabyte Volume Support in Solaris Volume Manager

Solaris Volume Manager has been enhanced with multiterabyte volume support. With this support, the Solaris Volume Manager can create, manage, and delete large (>1Tbyte) RAID 0 (stripe), RAID 1 (mirror), RAID 5, and soft partition volumes. In addition, this large volume support enables Solaris Volume Manager to construct volumes on large or EFI-labeled logical unit numbers (LUNs).

Solaris Volume Manager large volume support is not available for systems that run a 32-bit Solaris kernel. For example, systems that run the Solaris operating environment (x86 Platform Edition) or the Solaris operating environment SPARC 32-bit kernel cannot use large volume support.

For further information, see the Solaris Volume Manager Administration Guide.

See also SPARC: Multiterabyte Volume Support With EFI Disk Labels.

Reconfiguration Coordination Manager Support in Solaris Volume Manager

Reconfiguration Coordination Manager (RCM) support adds to Solaris Volume Manager the ability to respond appropriately to dynamic reconfiguration (DR) requests. This addition ensures that removal of devices under Solaris Volume Manager control is blocked with an appropriate warning until the devices are no longer in use. This warning prevents system administrators from accidentally removing active volumes from a DR-configured system.

For further information, see the Solaris Volume Manager Administration Guide.

Solaris Patch Update Feature

You can use the Update option of the Solaris Management Console's Patches Tool or the smpatch update command to analyze, download, and install recommended patches from the SunSolve OnlineSM web site.

This update feature was previously only available for systems that run the Solaris 2.6, Solaris 7, or Solaris 8 releases.

You must install the PatchPro 2.1 software on your system before running the update feature. Download the PatchPro 2.1 packages from http://www.sun.com/PatchPro. Then follow the instructions to install the software on your system.

For more information, see the smpatch(1M) man page.

Combine Data Address and Test Address for Singleton IP Network Multipathing Group

The use of a dedicated test IP address for failure detection on single-adapter IP network multipathing groups is no longer required. When failover is not possible because only one network information center (NIC) is in an IP network multipathing group, you can now combine the test address and the data address. The in.mpathd daemon uses a data address to detect failure when a test address is not specified.

For further information on Solaris IP multipathing, see the IP Network Multipathing Administration Guide.

Desktop Features

GNOME 2.0 Desktop

The GNOME 2.0 desktop is an advanced, intuitive desktop for the Solaris operating environment. The GNOME 2.0 desktop provides an alternative to the Common Desktop Environment (CDE), which was provided with the Solaris environment through several releases.

Xrender Extension

The new Xrender feature increases performance for applications, such as the StarOfficeTM software suite, that run on the Solaris operating environment. The Xrender feature provides a modern appearance for these applications. Xrender uses hardware processing for alpha-blending and transparency effects.

System Resources Enhancements

Extended Accounting Subsystem

In the Solaris 9 9/02 Update release, you can now use extended accounting processes in conjunction with the flow accounting module for IPQoS. For information about IPQoS, see the IPQoS Administration Guide.

For information about the extended accounting feature, see “Extended Accounting” in the System Administration Guide: Resource Management and Network Services.

A Perl interface to libexacct is available in the Solaris 9 4/03 Update release. This interface enables you to create Perl scripts that can read the accounting files which are produced by the exacct framework. You can also create Perl scripts that write exacct files.

The new interface is functionally equivalent to the underlying C API.

You can use the Perl interface to record system resource consumption on a task or process basis. Or, you can record consumption on the basis of selectors provided by the IPQoS flowacct module.

For information about the Perl interface to libexacct, see “Extended Accounting” in System Administration Guide: Resource Management and Network Services.

Language Support Enhancements

Unicode Version 3.2 Support

Solaris Unicode locales now support the Unicode Version 3.2. The Unicode Version 3.2 introduces 1016 new characters. This version also includes both normative changes and informative changes, as described in the Unicode Standard Annex #28: UNICODE 3.2 at the following Web site:

http://www.unicode.org/unicode/reports/tr28/

The UTF-8 character representation has been changed to a more secure form as specified in the Unicode Version 3.2. This feature implements the more secure UTF-8 character representation, form, and byte sequences in UTF-8 related iconv code conversions. This feature also implements all OS-level multibyte and wide character functions, such as the following:

Additional Keyboard Support

Software support for three additional keyboards has been added to the Solaris 9 4/03 Update release: Estonian keyboard Type 6, French-Canadian keyboard Type 6, and Polish programmer's keyboard Type 5. This software support gives users in Canada, Estonia, and Poland greater flexibility for keyboard input. The support modifies standard U.S. keyboard layouts to different language needs.

Refer to the Solaris 9 4/03 Release Notes for instructions.

Wubi Input Method

The Wubi input method (IM) is widely used in China. The encoding rule for Wubi IM is based on the radical or stroke shape of Chinese characters. Users can rapidly type Chinese characters through a standard keyboard rather than through slower, phonetic-based input methods.

Input Method Support for Indic

Input support for Indian regional language keyboards has been added to the Solaris operating environment. Indic language users can type Indic language characters by using their preferred keyboard layouts in the Solaris operating environment.

Seven Additional Indic Scripts for Support in Unicode Locales

Development Tool Enhancements

Smart Card Terminal Interfaces

Solaris smart card interfaces are a set of public interfaces for Smart Card Terminals. Card terminal vendors can implement these interfaces in a user-level shared library to provide device-level support for their smart card terminals in Solaris. The set of Solaris smart card terminal interfaces is based on card terminal interfaces that are available as part of the Linux Smartcard framework. Card terminal support libraries from Linux can be ported to Solaris with minimum effort.

Stack Check APIs

Stack Check APIs allow for advanced interaction with stack-checking compiler support available in ForteTM 7.0. These APIs should be used in applications that are compiled with stack checking enabled, and either manage their own stacks or attempt to detect their own stack overflows.

Developers who maintain their own thread library need to use the setustack interface to enable consumers of their library to compile with stack checking enabled.

See the stack_getbounds(3C), stack_setbounds(3C), stack_inbounds(3C), and stack_violation(3C) man pages.

Memory Allocation With libumem

libumem is a user-mode (nonkernel mode) memory allocator library. libumem has features that enable you to debug memory leaks and other aberrations that involve memory usage.

This feature is used in the same way that a standard application binary interface (ABI) allocator, such as malloc(), is used. A user-mode application requests an arbitrary number of bytes of memory. Then a pointer is returned that is loaded with the address of the allocated memory.

For further information, see the libumem(3LIB) man page.

A technical white paper about Solaris Memory Placement Optimization and Sun Fire Servers is available at the following Web site:

http://www.sun.com/servers/wp/docs/mpo_v7_CUSTOMER.pdf

Sun ONE Message Queue

The Solaris 9 12/02 Update release supports JMS messaging applications. These applications are based on Sun ONE Message Queue, a JMS provider. See Sun ONE Message Queue.

Note –

The Sun ONE Message Queue is a new feature for the SPARC platform in the Solaris 9 12/02 Update release. In the Solaris 9 8/03 Update release, the Sun ONE Message Queue is also available for x86 platforms.

Enhanced crypt() Function

This Solaris release includes new extensions to the crypt() function and introduces the crypt_gensalt()function. These enhancements allow administrators to change the algorithm that is used to obscure users' UNIX® login passwords.

Modules are included for MD5 and Blowfish. The MD5 modules are at crypt_sunmd5 and crypt_bsdmd5. The Blowfish module is at crypt_bsdbf.

Developers can create new modules for alternate password-obscuring algorithms. Application developers must use the crypt_gensalt() function instead of manually generating the salt string for passing to the crypt() function.

Modules for alternate algorithms are specified in the crypt.conf(4) file. The module_path field specifies the path to the shared library object that implements the two required functions:

For further information, see the crypt(3C) and the policy.conf(4) man pages.

New Flags for madvise() Function

The madvise() function enables the kernel to optimize access to a user-defined region of memory. This Solaris release includes three new flags for the madvise() function:

For further information on the madvise() function, see the madvise(3C) man page.

Linkers and Libraries Updates

The Solaris 9 Update releases include new linker-editor features such as string table compression, unreferenced section elimination, and unreferenced dependency detection. For the most current list of new linker-editor features in each Solaris 9 Update release, see “New Linker and Libraries Features and Updates” in the Linker and Libraries Guide.

Smartcard Middleware APIs

The Solaris Smartcard framework now provides low-level middleware APIs. These APIs can be used to exchange data with a smart card by using a smart card reader. The APIs can be used in platforms such as the Sun BladeTM and Sun RayTM systems. Applications that are written in the Java language or in C can use these interfaces.
