The Tru64 UNIX® Operating System is a 64-bit advanced kernel architecture based on Carnegie-Mellon University's Mach V2.5 kernel design, with components from Berkeley Software Distribution (BSD) 4.3 and 4.4, UNIX System V, and other sources. Tru64 UNIX is an implementation of OSF/1 R1.0, R1.1, and R1.2 technology, and the Motif® graphical user interface and programming environment.

Tru64 UNIX provides symmetric multiprocessing (SMP), real-time support, and numerous features to assist application programmers in developing applications that use shared libraries, multithread support, and memory-mapped files. The full features of the X Window System, Version 11, Release 6.5 (X11R6.5) from The Open Group are supported.

Tru64 UNIX complies with other standards and industry specifications, including major standards sponsored by The Open Group, POSIX, FIPS, and the System V Interface Definition (SVID). By providing support for SVID, Tru64 UNIX supports System V applications. The Tru64 UNIX Operating System is compatible with Berkeley 4.3 programming interfaces.

• A Java based interface for managing over the Web or from a PC
• A graphical interface based on X windows
• A Curses interface for character-cell environments
• A command-line interface for scripting, automation, and for auditing system configurations

SysMan's Division of Privileges (DoP) utility allows users to perform privileged actions without the need to know the root password.

SysMan also includes a comprehensive event management mechanism for posting, subscribing, and viewing all system events, including hardware and software.

The update installation procedure updates the operating system from Tru64 UNIX Version 5.1 or Version 5.1A to Version 5.1B, while preserving appropriate system files and existing user-customized files. The Installation Guide shows the successive update paths to reach if a system is running a version of the operating system other than Version 5.1.
During an update installation of the base operating system, Worldwide Language Support (WLS) software is automatically updated as well. It is not necessary to remove WLS software before updating the operating system or to update WLS software as a separate task.

At the beginning of the update installation process, an analysis of a Tru64 UNIX system is done to identify:

• Layered products that prevent the update from continuing
• Layered products that should be reinstalled after the update
• Fatal and nonfatal file system type conflicts
• Available disk space
• Unsupported hardware platforms

Cloning allows administrators to take a snapshot of a fully installed and configured system. Later, administrators can automatically install and configure other systems without the need to go through the set of installation and configuration steps. After a system's configuration has been saved, administrators can apply it manually or automatically to other systems at any time.

System cloning combined with user-defined scripts, which allow for customized scripts to be executed during different phases of the installation process, allow administrators to perform an unattended installation and configuration of a system. Administrators can use cloning for repetitive installations and configurations on multiple systems.

A RIS client can be booted from the following interfaces:

• Internal Ethernet
• The DE422 and DE425 EISA Ethernet option cards
• The DE203, DE204, and DE205 ISA Ethernet option cards
• The DE434, DE435, and DE436, DE500, DE504, DE600, DE602 PCI Ethernet option cards
• The DEFEA EISA family of FDDI option cards
• The DEFPA PCI family of FDDI option cards
• The DETRA Token Ring option card

Console firmware and all option firmware in the DMS or RIS server and in every client system must be compatible with the version of Tru64 UNIX system software that will be running on that system.

See the Release Notes Overview included with the Console Firmware CD-ROM, which is packaged along with the Tru64 UNIX Operating System software kit (QA-6ADAA-H8), to determine firmware version compatibility.

The Tru64 UNIX Server Extensions include support to install and operate systems in a dataless configuration. A server system maintains the root, /usr, and /var file systems for all client systems. The server maintains one copy of root for each client. The /usr file system is exported read-only and is shared by all clients registered in the environment. Each client has its own /var file system. Dataless clients access the file systems maintained on the server using NFS. A minimum of one disk drive is required on each client for dumping and swapping.

The Dataless Management Utility (dmu) enables the server to register and manage the software areas used by Tru64 UNIX dataless clients. BOOTP is the protocol used to boot the clients and mount the remote file systems.

Online addition and remove of CPUs (OLAR) is supported on AlphaServer GS160 and GS320 systems. This capability can be used to expand capacity, upgrade existing components, and replace failed components while the operating system services and applications continue to run. This functionality provides the benefits of increased system uptime and availability by avoiding scheduled and unscheduled downtime for maintenance and capacity upgrades. Online add and remove of CPUs within GS160/320 systems means that these CPUs can be physically removed, including the boot CPU and the interrupt handling CPU.

OLAR management is integrated with the SysMan suite of system management applications, which provides the ability to manage all aspects of the system from a centralized location.

• X11-capable display
• Personal computer running Windows 95, Windows 98, Windows NT, Windows 2000 and Windows XP.
• Character-cell terminal

The SysMan Station provides a graphical representation of the system and enables administrators to manage the system from a personal computer. The SysMan Station is a Java tool that is fully integrated with HP TruCluster Server Version 5.0A or later. SMS allows administrators to remotely manage systems from anywhere — PCs clients, UNIX workstations, or any Alpha system.

Administrators can access the Tru64 UNIX System Management Home Page, System Management Menu, SysMan Station, and the UniCensus Configuration reports easily from any browser using the dedicated 2301 HTTP port.

• Kernel Tuner displays and changes parameters of the kernel subsystem.
• Class Scheduler allows the administrator to prioritize jobs and tasks.
• Process Tuner displays, monitors, and manages system processes. A number of sort and filter options are provided to format the information display.
• Environmental Monitoring monitors the thermal, fan, and redundant power supply of Alpha systems that have prerequisite hardware sensor support. The functionality sets user-defined scripts, temperature levels, collection rate, and shutdown grace period, and can start or stop the environmental monitoring state.
• Collect is a lightweight, highly flexible performance collector. Collect can run continuously 7x24 and manage its own logs. For more information, see the Collect reference page.

Tru64 UNIX provides Web-Based Enterprise Management (WBEM) capabilities through integrating the Insight Manager™ Agents, insight_manager(5). Insight Manager enables Web-based device monitoring and fault management of local and remote system hardware and software resources. Administrators can access features from any browser using the HP dedicated 2301 HTTP port.

Insight Manager for Tru64 UNIX includes SNMP-based subagents and WBEM capabilities for presenting SNMP data through any Web browser. The SNMP subagents supply a rich set of HP Enterprise MIBs which provide hardware information, status, and statistics of CPU and memory boards, I/O devices, SCSI-based storage devices, Network Interface Cards, and Environmental devices, such as temperature sensors, fans, and power supplies.

Storage Management products and features provide an integral extension to Tru64 UNIX system management functionality. The following products include valuable storage management features that ship with the Tru64 UNIX base product and related information on storage features available through the purchase of layered products.

Tru64 UNIX Logical Storage Manager (LSM) is an integrated host-based solution for data storage management. Basic LSM functionality, including disk spanning and concatenation, is provided with the base operating system and is free of charge. Additional features, such as disk striping, mirroring, and a graphical user interface, are available with a separate license. LSM is RAID Advisory Board (RAB) certified for RAID Levels 0, 1, 0 + 1, and 5. See the LAYERED PRODUCTS section of these QuickSpec and the LSM QuickSpec for more information.

NetWorker^® provides automated backup and recovery of files on a local system. The SingleServer version is supplied free of charge with Tru64 UNIX and provides automated backup and recovery of the direct attached storage devices. Users can purchase upgrade licenses to access the benefits of the full NetWorker^® product from Legato Systems, Inc. See the LAYERED PRODUCTS section of this QuickSpec for more information.

• The iostat command (I/O statistics)
• The netstat command (network statistics)
• The vmstat command (virtual memory statistics)
• The who command

Tru64 UNIX provides the following service tools:
The sys_check is a data gathering and reporting tool gives the current state of a system, including configuration information, microcode information, and Tru64 UNIX parameter settings.
WEB-Based Enterprise Service (WEBES) is an extension of the HP industry-leading Web-Based Enterprise Management (WBEM) technology and provides a core of common service tool functionality across some HP product platforms. The tool functionality contained in the WEBES kit includes the following:

• Compaq Analyze (symptom directed hardware diagnosis tool)
• Compaq Crash Analysis Tool (symptom directed operating system software diagnosis tool)
• Revision and Configuration Management tool (collects system configuration and revision data)

• Compaq Analyze

Compaq Analyze is a hardware diagnosis software tool that provides analysis for single errors or fault events at a rudimentary level, as well as multiple event and complex analysis. Compaq Analyze is the enabling technology for indictment of failing CPUs in support of the CPU OLAR (online addition and removal of CPUs) functionality. Refer to the Compaq Analyze User Guide for details.

• Compaq Crash Analysis Tool (CCAT)

CCAT is a software application tool that helps service engineers and system managers to analyze operating system crashes on-site.

• Revision and Configuration Management (RCM)

The RCM tool collects system configuration and revision data information. The data is stored in the RCM Server at HP Services and the server is then used to create detailed revision and configuration reports.

The Tru64 UNIX file system architecture is based on the OSF/1 Virtual File System (VFS), which is based on the Berkeley 4.3 Reno Virtual File System. VFS provides a standard interface for file access regardless of the physical file system in which the files reside.

Tru64 UNIX supports the file system types described in this section.

The Advanced File System is a journaled, self-tuning, local file system that provides higher availability and greater flexibility than traditional UNIX file systems.

Administrators can resize file domains dynamically to allocate or deallocate storage while the system is running, and to set quotas for users, groups, and filesets. Quotas can have hard and soft limits, which specify a period of time that a quota can be exceeded.

Using transaction journaling, AdvFS provides increased file system integrity and recovers file domains in seconds rather than hours after an unexpected restart. The AdvFS defragment utility reduces the number of file extents in a file domain by making files contiguous, thus improving the read/write performance as less I/O operations are required to access a file. AdvFS also supports direct I/O. This feature supplies applications that do their own cache and I/O management – for instance a database – with the ability to bypass the AdvFS cache and I/O management algorithms and deliver near raw disk performance while still providing all of the system management benefits of a file system.

The AdvFS /, /usr, and /var filesets are configured during installation. The system has generous configuration capabilities. Administrators can mount 2^32-1 filesets and file domains.

Users can select Atomic Data Logging of a file, which guarantees user data integrity in the event of a system failure.

A single AdvFS file domain may contain up to 256 physical or logical volumes/LUNs with an AdvFS Utilities license installed. See the System Configuration and Tuning guide for volumes per domain, file domain, and fileset recommendations.

• The maximum physical volume size is 1 TB-512 K.
• The maximum number of files in a fileset is 2³¹. (This number is limited by the length of the tag that is used to uniquely identify a file in a fileset.)
• The maximum size of an AdvFS file and fileset is 16 TB - 512 K (2¹³ * 2³²), with an 8 K page size and a 31-bit page number.

AdvFS supports backups of mounted filesets. These backups are done with the vdump or rvdump utilities, which back up files and any associated extended attributes (including ACLs) from a single mounted fileset or clone of the fileset to a local or remote storage device. For more information, see the AdvFS Administration guide. The vrestore and rvrestore commands restore any associated extended attributes, including ACLs, in the archive data.

AdvFS includes the fixfdmn file system repair utility. This utility performs in-place repair of AdvFS file system metadata. This is a first generation, offline, in place, AdvFS metadata repair tool. The goal of this tool is to re-enable to mount an unmountable damaged file system after it has been repaired for mounting and I/O operations.

An AdvFS API exists for applications needing access to AdvFS-specific file attributes.

The disk-structure analysis commands allow the system administrator to examine the low-level structures of files, filesets, and file domains. The verify and slavage utilities may also be useful if a file system has become unmountable by the system disk due to hardware or software problems.

The right to use the Advanced File System is granted by the Tru64 UNIX Operating System license.
AdvFS Utilities is a separately licensed layered product that expands the capabilities of AdvFS as follows:

• Permits adding more than one volume to a file domain.
• Enables cloning – enable the application to remain online during backup by creating a read-only copy (clone) of an active fileset.
• Performance tuning, such as striping files across multiple volumes to improve read/write performance, balancing the domain to even out the percentage of free space among the volumes of a multivolume file domain, and migration to optimize disk usage.
• Enables creating a trashcan directory to store files that are deleted.
• Full support for hardware-initiated cloning and snapshot based 3^rd party backup solutions.
• Takes advantage of physical storage volume growth.

See the LAYERED PRODUCTS section of these QuickSpecs for more information on AdvFS Utilities.

Tru64 UNIX NFS V2 allows transparent file access over TCP/IP networks. The Network Information System (NIS) is provided for centralized system management of files. The automount service automatically mounts and unmounts NFS file systems. AutoFS provides the same services as the automount daemon but provides greater scalability and improved performance. The NFS locking service allows advisory and record locks to be used with remotely mounted files. Automount will be retired in a future release of the operating system. Instructions for migrating from automount to autofs have been provided in the Network Administration: Services Guide. Additional instructions for migrating from automount to autofs in a cluster can be found in the TruCluster Server Release Notes.

Tru64 UNIX provides an NFS V3 server and client protocol implementation in addition to V2. NFS V3 includes 64-bit support for file access, exclusive create semantics, negotiable transfer sizes, safe asynchronous writes, added support for access checking, and other changes designed to increase efficiency and performance. NFS file systems can use either the UDP or TCP transport protocols.

Network Lock Manager (NLM) V4 includes support for files larger than 2 GB. Support for additional over-the-wire error code is also provided. NLM V3 is supported for NFS V2 compatibility.

V2 PC-NFS server support is provided to enable connectivity from PC-NFS 5.1B, V5.1A, 5.1, 4.0, and 3.5 clients.

• Level 2 of Interchange
• Level 1 of Implementation, which enables the user to mount single-volume CD-ROMs that are formatted in compliance with ISO 9660 as a local file system
• Listing and examination of files using standard UNIX utilities and programs
• Reading of files and directories using the standard POSIX system interface
• NFS export mounted ISO 9660 file systems
• Support for the High Sierra Group extensions that provide compatibility with older-format CD-ROMs

CDFS also supports CD-ROMs recorded using the Rock Ridge Interchange Protocol, Revision 1.09, August 1991. Rock Ridge specifies the use of the extension fields that are defined by ISO 9660:1988, and it uses those extensions to provide the following information:

• File owner, file group, file permissions
• Additional file types (symbolic links, device special files, named pipes)
• setuid, setgid, and sticky bits
• Hard link counts
• POSIX file names (mixed case names, unstructured names, and longer names than ISO-9660:1988 allows)
• Deep directory hierarchies (greater than eight levels)
• File time stamps

XCDR extensions allow users to examine selected ISO 9660 attributes through defined utilities and shared libraries. A system administrator can substitute different file protections, owners, and file names for CD-ROM files.

CDFS supports the organization of multiple sessions on one CD-ROM volume. The maximum number of CDFS mounts is 512. Note that the contents of all sessions are available as one file system and are not separately available. Users can access DVD disks using the CDFS file system.

The Tru64 UNIX implementation of DVDFS is based on the ECMA 167 Universal Disk Format (UDF) specification Version 2.00.

DVDFS gives the administrator the ability to mount and read UDF formatted Digital Versatile Disks on a single node as well as in a cluster.

Tru64 UNIX provides comprehensive protection for IPv4 and IPv6 network traffic through support of the IPsec protocol suite. Encryption, data-origin authentication, data integrity protection, and compression of encrypted data is available through the AH, ESP, and IPCOMP protocols, supported in both tunnel and transport modes. Encryption can be performed using the Advanced Encryption Standard (AES) and Data Encryption Standard (DES and 3DES). Authentication can be performed using the SHA-1 and MD5 algorithms.

The Internet Key Exchange (IKE) protocol is fully supported for authentication and key exchange. Authentication can be via pre-shared keys, or through RSA or DSA certificates.

IPsec security policy is managed through the SysMan graphical user interface. IPsec protection cannot be applied to traffic which uses the cluster alias feature of the TruCluster product.

The Packetfilter software interface allows an application to send and receive packets directly to or from a LAN (Ethernet or FDDI). The Packetfilter provides flexible filtering of incoming packets, so that many such applications can run simultaneously.

The Tru64 UNIX Packetfilter supports two filtering models: the CMU/Stanford model supported in ULTRIX, and the BSD Packet Filter (BPF), which provides more flexible and efficient filtering. BPF was developed by the University of California, Lawrence Berkeley Laboratory. The packetfilter pseudo-driver can support up to 255 simultaneous open filters (each filter is usually mapped to one instance of an application program).

Several public domain applications that use the Packetfilter are integrated in Tru64 UNIX, including rarpd, tcpdump, tcpslice, nfswatch, and nfslogsum.

The Tru64 UNIX Asynchronous Transfer Mode subsystem supports the ATM Forum's User-Network Interface (UNI) V3.0 and V3.1 specifications, including the Interim Local Management Interface (ILMI) protocol for registration of up to 32 addresses per interface, UNI signaling for point-to-point connections, and best-effort and CBR VCs for AAL5 PDUs. Also, per-VC cell pacing (to limit the rate at which an end-system transmits) is supported.

The ATM subsystem supports Classical IP (RFC 1577), including support for multiple IP subnets, per-VC MTU negotiation, and packetfilter access to data into and out of the host.

LAN Emulation over ATM is supported (Ethernet and IEEE 802.3 frames only), for carrying IP and LAT protocols. Support is based on the ATM Forum V1.0 specification. Packetfilter access is provided to emulated LAN data into and out of the host.

Tru64 UNIX provides limited support for IP switching over ATM, based on the Ipsilon Networks Inc. reference model (RFC 1953 and 1954). Only one IP switching network device is supported per host, and an ATM adapter used for IP switching cannot simultaneously support ATM Forum UNI or ILMI protocols.

The ATM subsystem (except IP switching and PVCs) can be configured with the atmsetup utility to start automatically at boot time.

Tru64 UNIX does not support the UNI V3.0 and V3.1 specifications for full ATM Simple Network Management Protocol (SNMP) Management Information Bases (MIBs), point-to-multipoint connections, Operations and Maintenance (OAM) flows, VBR VCs, AAL1, AAL3/4, or raw AAL.

Tru64 UNIX supports the Level 2 end-system IP Multicast functionality, specified in RFC 1112, on Ethernet and FDDI. The implementation provides integrated multicast address management for multi-protocol environments.

The Tru64 UNIX implementation also provides kernel routines for encapsulating IP tunnels to enable wide area IP Multicast routing.

These routines include kernel code from public domain Multicast support Version 3.5 and mrouted (Version 3 Copyright 1989 by the Board of Trustees of Leland Stanford University), which provides the Distance Vector Multicast Routing Protocol (DVMRP).

Tru64 UNIX supports the Domain Name System (DNS) as described in RFC 1034 and RFC 1035, providing a host name and address lookup service for the Internet network. The Tru64 UNIX implementation of the Domain Name System is based on BIND Version 8.2.2p5 . The user can use BIND to supplement the host's database.

Tru64 UNIX also supports the Sun™ Network Information Service (NIS), formerly known as Yellow Pages (YP). NIS can be used to replace or supplement hosts, aliases, group, networks, password, protocols, rpc, and services databases.

• RLOGIN:7,043*
• Telnet:12,395*
• LAT:4,575*

*These numbers can vary depending on hardware configurations and user workloads.

The mail setup utility, /usr/sbin/mailsetup, and the mail configuration utility, /usr/sbin/mailconfig, will be retired in a future release of the operating system, but not before June 2003.

Prior to that retirement HP intends to introduce a "Unified Sendmail Configuration" utility which will be available as part of SysMan. This utility will encompass all the features of /usr/sbin/mailconfig and usr/sbin/mailsetup and will include advanced features for Sendmail configuration (masquerading, virtual hosting, anti-spam and ldap).

The Tru64 UNIX Operating System, running Enhanced Security, is designed to meet, and in some cases exceed, the requirements of the C2 evaluation class of DoD 5200.28-STD "Trusted Computer System Evaluation Criteria," also known as the Orange Book.

Tru64 UNIX supports various configurations and setup scripts, which allow selection of such desired Enhanced Security features as extended passwords, audit, and access control lists (ACLs).

System administrators can choose between command-line interfaces or GUIs.

Tru64 UNIX supports various configurations and setup scripts, which allow selection of such desired Enhanced Security features as extended passwords, audit, and access control lists (ACLs).

All security mechanisms on Tru64 UNIX are part of the Security Integration Architecture (SIA), which isolates security-sensitive commands from the specific security mechanisms. This eliminates the need to modify the security-sensitive commands for each new security mechanism.

• Secure Shell Software — SSH V1.1 is bundled with the operating system and is based on Secure Shell Version 2.4.1 software. The Secure Shell software is a client/server software application that provides a suite of secure network commands that can be used in addition to or in place of traditional network commands (such as telnet, ftp and the r* commands). The Tru64 UNIX Secure Shell Version 1.1 software implementation is cluster aware and includes one of a kind support for securing the srcmd libc function. When enabled it transparently secures any application that uses the libc rcmd function including the r* commands (rsh, rcp, and rlogin).
• Common Data Security Architecture (CDSA) — CDSA has been integrated into the base operating system.

Tru64 UNIX includes the following C2 security features:

• Discretionary Access Controls (DAC) — Allows users to define how the resources they create can be shared. Optional ACLs provide greater granularity of file system object protection at the individual user level than the default DAC protection. The ACL mechanism is designed to POSIX.1e draft 13 with some draft 15 enhancements.
• Auditing — Allows users to monitor normal and unauthorized usage of a system with a choice of a GUI or command-line interface.
• Identification and Authentication — Password length and lifetime are based on the Department of Defense Password Management Guideline (Green Book). Features include extensive login controls, such as automatic account lockout, account vacationing, per terminal settings for delays and maximum consecutive failed logins, password usage history, and system-generated password.
• Object Reuse — Ensures that the physical storage that is assigned to shared objects or that is released prior to reassignment to another user does not contain data from previous users.
• Integrity — Allows users to validate the correct operation of hardware, firmware, and software components of the Trusted Computing Base (TCB).
• System Architecture — A separate execution domain is maintained for the Trusted Computing Base (TCB) components using hardware memory management to protect the TCB while it is executing.

• Allows a virtual page in the process address space to be mapped to the most appropriate multiple-page granularity option supported by the system's physical memory.
• Uses threshold values set on a per memory-type basis to determine whether a memory allocation request is eligible for use of the extended page sizes.

• Tru64 UNIX provides the family of Merant DataDirect software products to enable ODBC and JDBC connectivity for your applications. This is optional software for use in developing and deploying applications and is licensed as part of the Tru64 UNIX operating system license.
• SequeLink ODBC Edition is a universal ODBC client component. DataDirect SequeLink ODBC provides transparent connectivity to almost any type of client, network, server, or database.
• For developers working with Java, JDBC provides Java applications to access data sources and databases across platforms. The SequeLink Java Edition is a universal standards-based implementation of JDBC. It is also flexible in design, providing scaleable connectivity from multivendor client, server, and Web environments to industry-leading relational databases. It is optimized and tuned for the Java environment, extending the functionality and performance of existing systems and easily incorporating new technologies.

• Netscape Communicator 4.76 — The Netscape Communicator Internet Client Worldwide Web browser.
• Netscape Browser 6.2.3 — Tru64 UNIX Version 5.1B includes the Netscape 6.2.3 Web Client, an XML enabled browser by which users can access the Platform Management Utility for the ES80 and the GS1280.

CDE is the default user interface for Tru64 UNIX.

POSIX Threads provide a pthreads interface that complies with the POSIX 1003.1c semantics. The POSIX Threads implementation provides user space threads which are supported by and cooperate with the threaded kernel of Tru64 UNIX in a comprehensive two-level scheduling model that transparently maintains full concurrency when a thread blocks. In addition, for building libraries whose routines can be called in either a single-threaded or multi-threaded context, POSIX Threads provide a thread-independent services (TIS) interface.

The Visual Threads tool is available to help programmers analyze and debug multi-threaded applications for common problems such as deadlock, protection of shared data, and thread usage errors. It can also be used to monitor the thread-related performance of the application.

HP recommends the use of Micro Focus COBOL, as resold by HP, for Tru64 UNIX based COBOL application development. For customers developing Compaq COBOL applications on HP OpenVMS who also want to deliver Compaq COBOL based applications on Tru64 UNIX, Compaq COBOL run-time libraries are licensed with Tru64 UNIX. The Compaq COBOL compilers are available as a separately licensed layered product.

The Compaq COBOL run-time support libraries (libcob, libots2,) enable users to run previously compiled programs that require the Compaq COBOL libraries at run time. These libraries support COBOL program functions in areas including file input and output, decimal arithmetic, the COBOL ACCEPT/DISPLAY statements, STRING/UNSTRING operations, CALL and CANCEL, and more.

Tru64 UNIX provides the Compaq Software Development Kit (SDK) v 1.3.1 for the Java™ Platform. The SDK implements Sun Microsystems' Java 2 SDK, Standard Edition (J2SDK), v 1.3.1.

The SDK includes the basic set of command-line tools, the Class Libraries, and virtual machine implementation needed to develop and run Java applets and applications. The SDK also includes the Compaq Fast Virtual Machine (Fast VM) as the default SDK VM. The Fast VM provides optimal runtime performance on Tru64 UNIX systems.

The SDK passes 100 percent of the tests provided in Sun's Java Compatibility Kit. The SDK is included as part of the Tru64 UNIX Operating System kit and is subject to the terms of the Base license for Tru64 UNIX, as well as the additional SDK license.

The version of the Tru64 UNIX Operating System described in these QuickSpecs qualifies as a Minor Functional version release.

The Tru64 UNIX Operating System license provides the right to use the software as described in these QuickSpecs, and is furnished under the licensing of Compaq Computer Corporation's Standard Terms and Conditions. Licenses (including all Base, SMP,and User Licenses) for prior versions must be updated to this version either through the purchase of a Service Agreement that includes the rights-to-use new versions, or through the purchase of Update Licenses.

There are five different types of Tru64 UNIX Operating System licenses:

• Operating System Base License (QL-MT4A*-6*) Update License (QL-MT4A*-7*)
• Symmetric Multiprocessing (SMP) Extension to Base License (QL-MT4A9-6*) Update (QL-MT4A9-7*)
• Tru64 UNIX Hardware Partitioning License (QM-MT4AA-AA) Update License not required.
• Concurrent Use Licenses (QL-MT7AM-3*) Update (QL-MT7AM-5*)
• Unlimited User Licenses (QL-MT7A*-AA) Update (QL-MT7A*-RA)

The following sections describe each type of license.

(QL-MT4A*-6* LMF Product Name: OSF-BASE)
This license grants the right to noninteractive use of the file, application, batch, print, and compute services of Tru64 UNIX Operating System on a single processor.

This license also authorizes up to two concurrent interactive users of the system. An interactive user, either a person or device, is one that is logged in to a Tru64 UNIX processor or is interactively using the operating system software by means other than a login. The two interactive users authorized as part of the Operating System Base License are additive with Concurrent Use License quantities, but may not be separated from the Operating System Base License.

In addition to the two interactive users, login as root is authorized for system management purposes only. If a Tru64 UNIX Base License is not registered and activated using the LMF, then login by root only is permitted for system management purposes.

The Operating System Base License is a prerequisite for Concurrent Use Licenses, Unlimited Interactive User Licenses, Hardware Partitioning Licenses, and SMP Extensions to Base Licenses.

(QL-MT4A9-6* LMF Product Name: OSF-BASE)
SMP Extensions extend the Operating System Base License to enable symmetric multiprocessing capability on those Tru64 UNIX systems supporting SMP. SMP Extensions to Base are permanently tied to the Operating System Base License and may not be separated from the Operating System Base License if an SMP board is removed from the system.

One SMP Extension License is needed for each active processor in the SMP system that is added to the initial processor authorized by the Operating System Base License.

SMP Extensions grant the right to use the same version of the Operating System software as permitted by the corresponding Operating System Base License at the time when the SMP Extension is installed.

(QL-MT7AM-3* LMF Product Name: OSF-USR)
An Operating System Base License is a prerequisite for Concurrent Use Licenses on the same system.

These licenses grant the right to interactive use of the Tru64 UNIX Operating System. The Concurrent Use Licenses are available in various quantities, which can be combined to match any total desired.

Multiple user licenses of the same or different quantities may be installed and used together on a given system to authorize system use by the sum of their quantities. These user licenses authorize users in addition to the two users authorized as part of the Operating System Base License.

Concurrent Use Licenses are redesignatable and can be installed and used only on a single Tru64 UNIX system at a time.

An interactive user, either a person or device, is one that is logged in to a Tru64 UNIX processor or is interactively using the operating system software by means other than a login.

(QL-MT7A*-AA LMF Product Name: OSF-USR)
An Operating System Base License is a prerequisite for an Unlimited User License for use on the same system.

This license grants the right to use the Tru64 UNIX Operating System by an unlimited number of interactive users on a system.

An Unlimited Interactive User License grants the right to use software versions authorized under the Operating System Base License in effect at the time of the grant of the Unlimited User License.
