The Internet connects many universities, government research labs, military installations, and private businesses. Internet Protocol IP Protocol that resides in the Internet layer and performs two major functions: Internetwork addressing and fragmentation of messages.
InterNIC Registration Services Organization that provides the Internet community with registration, directory, database and information services. The bit address is composed of two parts: network number and host number. IP datagram Basic unit of information passed across the Internet; contains source and destination addresses, the data, and fields that define the length of the datagram, the header checksum, and flags to say whether the datagram can be or has been fragmented.
An IP datagram is to the Internet what a hardware packet is to a physical network. With NFS, users and programs can access files on remote computers as if they were local files. Users do not need to know or care where the files are actually stored. Routing Network layer function, implemented in intermediate systems, that determines the path along which data travels to its destination and the movement of that data. Subnet mask Mask used to determine the subnetwork in the IP address.
Each bit that is turned on binary one in the mask is interpreted as part of the network and subnetwork address. Synonymous with network mask. Transmission Control Protocol TCP Internet transport level protocol that provides the reliable, full-duplex, stream service on which many application protocols depend. TCP allows a process on one host to send a stream of data to a process on another.
It is connection-oriented in the sense that before transmitting data, participants must establish a connection. Each host has a unique name and address. The local host is the system you are using, and the remote host is the system with which you are communicating. Hosts are connected by lines that carry information between the hosts. The line is the physical path over which data can pass from one host to another. Examples of lines are telephone lines, fiber-optic cables, and satellites.
Information is transmitted in small packets of data rather than as a continuous stream from host to host. For example, a file to be transmitted from one host to another is divided into many small packets that are sent across the network one at a time.
Each packet contains information about the address of the destination host. At the destination, the packets are reassembled. The packets that comprise the network traffic are combined multiplexed onto high-capacity machine interconnections for transmission across the network or internet. Because packets from different sources are mixed together, many users can use the same line simultaneously.
Individual packets can take different paths to the destination. The process of directing a data message from a source host to a destination host is called routing. For hosts not directly connected to each other, data can be forwarded from the source to the destination through intervening hosts. Two or more networks can be interconnected using gateways to form an internet, as illustrated in Figure A gateway is a computer that is connected to two networks and routes packets from one to the other.
FTP also provides authentication control. Clients must correctly enter a login name and password to the server before they can request file transfers. Unlike network hardware addresses, which are hardcoded and fixed, an IP address is assigned by a network administrator. The cell controller is combined with four CPU chips into the computing cell in the sx chipset architecture.
The rx, rx, and Superdome servers provide a varying number of sx chipset cells. Any additional adapters, or movement to another server environment, requires you to move to U SCSI adapter technology. The internal box also has two external ports. This command deletes the contents of the SEL. Note the following example:. The hot-plug controller version will be displayed. A display of indicates version 1.
For more information, refer to the hardware documentation that is provided with your server. On Integrity servers with the minimum amount of supported memory MB , the following message appears when booting from the installation DVD:.
You can continue with the installation. For Version 7. For details about OpenVMS operating system support, see the chart on the following website:. If you are running other versions of OpenVMS that are no longer supported, you must do multiple upgrades in accordance with upgrade paths that were documented for earlier versions. During a concurrent upgrade, you must shut down the entire cluster and upgrade each system disk. No one can use the cluster until you upgrade and reboot each computer.
Once you reboot, each computer will be running the upgraded version of the operating system. During a cluster rolling upgrade, you upgrade each system disk individually, allowing old and new versions of the operating system to run together in the same cluster a mixed-version cluster. There must be more than one system disk. The systems that are not being upgraded remain available. If you are upgrading in a cluster environment, rolling upgrades are supported from Version 7.
If you have other versions in a cluster, you cannot do a rolling upgrade until those versions are upgraded to a supported version. Mixed-version support for these versions require the installation of one or more remedial kits. For more information, see Section 4. HP currently supports only two versions of OpenVMS regardless of architecture running in a cluster at the same time.
Only two. WE0: delete active inet address node1. COM procedure. This will prevent these command procedures from executing twice. With Version 8. For example:. See Section 1. If you upgrade to Version 8. So, under normal conditions, you will not see any striking differences in behavior during an OpenVMS Version 7.
Because no records are added, the expected additions or other alterations to SYSGEN parameters will not be made, which could lead to resource exhaustion. Developers and testers of software products should be aware of this requirement; it may also be of interest to system managers.
This new behavior is intended to protect both the users and providers of layered products. If this happens, answer YES to the question, "Do you want to terminate? This chapter contains information about OpenVMS associated products. For notes about using compilers, linkers, and run-time library routines, see Chapter 5. The reports contain the product name and version, the operating system version required to support the product, and the volume ship date for the product.
The information in these tables is continually evolving and is subject to change. The reports are intended for public distribution and are updated monthly. The information is not provided in these release notes because of the changing nature of the information.
The component installation kits and documentation are split across the two CDs. DECdfs Version 2. If you try to use an older version of DECdfs, you will get an error message. Remove or comment out the following line:. Ensure that the Java environment is set up systemwide for all processes. Ensure that the browser clients use the Sun Java Plugin Version 1. The older version shipped with the. OpenVMS operating system may overwrite a newer version.
FMS V2. However, GCM is frequently updated. Check regularly for new versions of the software on the following web page:. Users are still required to have a DECram license.
For details about removing old versions of DECram before you upgrade to Version 8. If you try to load any old versions of DECram, you will get the following error message:. However, HP no longer provides support for designing and implementing user-written transports based on the updated transport interface. If you have implemented a custom transport and want to migrate that transport to the DECwindows Motif Version 1.
The functional replacement for SWS Version 1. SWS Version 1. The Pascal V5. This chapter provides information for all users of the OpenVMS operating system. It includes information about commonly used commands and utilities. SeaMonkey Version 1. When you install SWB Version 1. You can ignore this warning. In this example, it is EWA:. If this happens, redo the steps listed above. On OpenVMS systems, enumeration is the process by which devices are assigned a letter and number following the OpenVMS generic device-type nomenclature.
OpenVMS Version 8. The names of the serial ports can change, because at least one serial port can serve more than one function.
The serial port selected as primary console is always OPA0. Unless the serial port of the Integrated Lights Out iLO Management Processer MP is selected as the primary console, it is not connected as a serial port and is not exposed by the operating system. It is not suitable for general-purpose use because it cannot support the data rates a general-purpose serial port needs to support. This is an optional component in most systems. The following table provides serial-port naming for the HP Integrity platforms listed.
The device selected as primary console is always named OPA0. It has been changed by OpenVMS to informational, or level However, with Version 8. Prior to Version 8. If you do, it works as expected, but any failing status is only displayed and not returned to DCL. To mount the Freeware CDs, insert one of the CD volumes into the CD drive and enter the following command to mount and display the contents of the Freeware volume.
COM Freeware menu system interface has been removed from Freeware 8. You can directly access the contents of the Freeware V7. This is the preferred way to access the contents of the Freeware V7. COM to stop the system may not work as expected. However, it will continue to reset as though a reboot had been requested. The software will continue to be available on the following website for earlier versions of OpenVMS:.
You can continue with the installation by answering "NO" to the "Do you want to terminate? The installation will continue successfully. The following sections describe corrections and additions to various manuals in the OpenVMS documentation set.
It does this by intercepting Linker diagnostics and converting mangled names reported by the Linker to their original names, using the information in the demangler database.
This support is not available currently, but will be available in a future update kit. For more information, see the OpenVMS website.

This chapter describes the following tasks: Task Section Getting information about devices on the system Section 7. Local Digital Storage Architecture DSA devices use a controller letter of A regardless of the physical controller the device resides on.
Use of a single controller letter requires that the unit number for each local DSA device be unique. Duplicate unit numbers are possible if the local disks reside on different controllers. If the device is to be accessed or dual-ported by two computers or HSC subsystems, you must identify the device with a unique, path-independent name that includes an allocation class.
Device protection is RWPL read, write, physical, logical. In addition, if a volume has a protected subsystem enabled, it also appears in the display. The following command requests a full informational display about each DU device. Volumes are improperly dismounted when, for example, the system crashes.
