OpenVMS Version 8.2 New Features

Chapter 1
Summary of HP OpenVMS Version 8.2 New Features

OpenVMS Version 8.2 introduces a major new platform release for the OpenVMS operating system, HP Integrity servers. OpenVMS continues to deliver the highest levels of availability, scalability, flexibility, performance, and security that are required for operating in a 24x365 environment. With more than 20 years of proven reliability, OpenVMS continues to enhance its availability and performance by including new technology in the base operating system and in the OpenVMS Cluster software environment.

1.1 Summary Table

OpenVMS Version 8.2 includes all the capabilities of OpenVMS Version 7.3--2 plus the new features added to the OpenVMS operating system. Table 1-1 summarizes each feature provided by OpenVMS Version 8.2 and presents these features according to their functional component (general user, system management, programming, and associated products).

1.2 Major Differences Between OpenVMS Alpha and OpenVMS I64 Systems

The following list describes some of the very pronounced differences between Alpha and I64 platforms:

  • Consoles and console line connections
    The Integrity server allows console line connections by two different serial lines on current Integrity platforms. One serial line connects to the BMC console and the other to an optional Management Processor (MP). In addition, the Management Processor allows for a network connection and TELNET access for even more management flexibility.
    Both consoles allow for management of hardware and can perform functions such as resetting the system or powering on or off the system. The Management Processor is the preferred method, because it provides more management features than the BMC console.
  • Connecting to the system console
    The BMC and MP consoles allow for connection to the system console. For Integrity servers, this is the EFI shell. The mechanism for setting up boot devices and boot options are very different from the Alpha SRM console. In addition, once the system is booted, the EFI shell is no longer available. On Alpha, you can still get back to the SRM console while the system is booted.

  • Bootable devices for Integrity servers
    Bootable devices for Integrity servers have a FAT partition with the initial bootstrap programs.The EFI shell can find and read this partition. The system is booted by running an initial bootstrap program called vms_loader.efi, contained in the FAT partition.
    There is no environment variable that specifies the boot device. Instead, the EFI shell allows for the creation of menu items that execute vms_loader.efi on a specific disk.
  • Console environment variables on Integrity servers
    The boot flags can be specified by vms_flags. On Alpha, the name BOOT_OSFLAGS is used. There are no environment variable to configure SCSI or LAN devices. Any LAN configuration settings would need to be done within the LANCP program.
  • Licensing
    While the basic LMF management functions remain the same, new licensing practices for OpenVMS I64 differ from what is available for OpenVMS Alpha and OpenVMS VAX. The primary differences involve:
    • The way license units are assigned and counted
    • The types of licenses offered
    • Update licenses:
      • For I64 systems, update licenses are not offered. A customer must be an active Software Updates Service customer to be eligible to receive new revisions of software or the customer must purchase the product again. Information regarding Software Updates service and other HP Service offerings are available at:
        http://www.hp.com/hps/software
      • For Alpha systems, update licenses continue to be available for non-Service customers or Service customers whose contract has lapsed.

    Refer to the HP OpenVMS License Management Utility Manual for information about the licensing for OpenVMS I64 systems.
  • Privileged architecture library code (PALcode) functions moved into OpenVMS
    OpenVMS Alpha calls PALcode to execute atomic functions such as memory barrier (MB), Halt and Bugcheck. These functions are now part of OpenVMS I64 instead of in the console firmware.
  • OpenVMS Calling Standard
    The implementation of the OpenVMS Calling Standard on the Intel® Itanium® processor family is based on the Intel Calling Standard. OpenVMS extensions were added for compatibility with VAX and Alpha code.
    If your current application has detailed knowledge of the internals of the calling standard format, refer to the HP OpenVMS Calling Standard for information about the OpenVMS Calling Standard implementation for OpenVMS Version 8.2.

  • IEEE floating-point format
    AlphaServers support VAX floating-point data types and IEEE floating-point data types in hardware. Integrity servers support IEEE floating-point in hardware but VAX floating-point data types are supported in software. The OpenVMS I64 compilers provide the /FLOAT_D_FLOAT and /FLOAT_G_FLOAT qualifiers to enable you to produce VAX floating-point data types. If you do not specify one of these qualifiers, IEEE floating-point data types are used.
    Refer to Porting Applications from HP OpenVMS Alpha to HP OpenVMS Industry Standard 64 for Integrity Servers manual for more information about IEEE floating-point data types as they apply to OpenVMS Version 8.2.

Prior to getting started with an Integrity server system, read the HP OpenVMS Version 8.2 Release Notes, HP OpenVMS Version 8.2 Upgrade and Installation Manual, and this manual.
