OpenVMS VAX Version 7.1 Upgrade and Installation Manual

Some files that can be redirected are the system authorization file, the queue manager database, the audit log file, and batch log files. Some files that can be reset, copied, and purged are the operator log file, the accounting log file, and network log files. For more information about these facilities see the OpenVMS System Manager's Manual, the OpenVMS DCL Dictionary, or the utility reference manual for the utility whose files you want to offload.

H.7.4 Offloading Nonessential Files

Some of the files included with OpenVMS VAX Version 7.1 can be redirected to an alternate device during the installation or upgrade procedure. This can save many valuable system disk blocks while providing quick access to these files. For a small system disk configuration with multiple disks, this approach is recommended if you want the the Help Message utility (MSGHLP) to be available on line.

boot, bootstrap: The process of loading system software into a processor's main memory. This guide uses the term boot to refer to this process.

boot command procedure: A program, stored on the console fixed disk, that is used to boot the OpenVMS operating system from a specified controller. Digital provides a boot command procedure for each controller that the processor supports.

boot name: The abbreviated name of the boot command procedure you use to boot the system.

boot server: A VAX computer that is part of a local area VAXcluster. The boot server is a combination of a MOP server and a disk server for the satellite system disk. See also satellite node.

CI only VAXcluster: A computer system consisting of a number of VAX computers. It uses only the computer interconnect (CI) to communicate with other VAX computers in the cluster. These computers share a single file system.

computer interconnect (CI): A type of I/O subsystem. It links VAX computers to each other and to HSC devices. See also Hierarchical Storage Controller (HSC) device.

DECW$TAILOR: A software program that lets you add or remove DECwindows files from your system disk.

device name: The name used to identify a device on the system. A device name indicates the device code, controller designation, and unit number.

disk server: A VAX computer that is part of a local area VAXcluster. This computer provides an access path to CI, CSSI, and locally-connected disks for other computers that do not have a direct connection.

Hierarchical Storage Controller (HSC) device: A self-contained, intelligent, mass storage subsystem that lets VAX computers in a VAXcluster environment share disks. Examples are the HSC50 and the HSC70.

HSC drive: Any disk or tape drive connected to an HSC device is called an HSC drive. A system disk on an HSC drive can be shared by several VAX computers in a VAXcluster environment.

InfoServer: A general-purpose disk storage server that allows you to use the distribution compact disc to install the operating system on remote client systems connected to the same LAN (local area network).

local area VAXcluster: A configuration consisting of one or more VAX computers that act as a MOP server and disk server, and a number of low-end VAX computers that act as satellite nodes. The local area network (LAN) connects all of the computers. These computers share a single file system.

local drive: Any drive that is connected directly to a VAX computer.

media: Any packaging agent capable of storing computer software. Examples: compact discs, magnetic tapes, floppy diskettes, disk packs, tape cartridges.

MOP server: A computer system running DECnet that downline loads VAXcluster satellites using the DECnet MOP protocol.

satellite node: A VAX computer that is part of a local area VAXcluster. A satellite node is downline loaded from a MOP server and then boots remotely from the system disk served by a disk server in the local area VAXcluster. See also boot server, disk server, MOP server.

save set: The format in which the Backup utility stores files. The OpenVMS operating system is shipped in this format.

scratch disk: A blank disk or a disk with files you no longer need.

source drive: The drive that holds the distribution kit during an upgrade or installation.

spin up, spin down: To spin up means to bring a disk drive up to operating speed; to spin down means to bring it to a gradual stop.

standalone BACKUP: A subset of the BACKUP utility that is booted into main memory instead of running under the control of the OpenVMS operating system. Standalone BACKUP is used to back up and restore the system disk and to install OpenVMS operating system software.

standalone system: A computer system with only one VAX computer.

system disk: The disk that contains or will contain the OpenVMS operating system. An OpenVMS system disk is set up so that most of the OpenVMS files can be shared by several VAX computers. In addition, each computer has its own directory on the system disk that contains its page, swap, and dump files.

target drive: The drive that holds the system disk during an upgrade or installation.

transaction log: A log used by DECdtm services to record information about transactions. The Log Manager Control Program (LMCP) is used to create a transaction log.

UETP (User Environment Test Package): A software package that tests all the standard peripheral devices on your system, various commands and operating system functions, the system's multiuser capability, DECnet for OpenVMS, and the VAXcluster environment.

VAXcluster environment: A computer system consisting of a number of VAX computers. There are three types of VAXcluster environments: CI only, local area, and mixed interconnect.

VMSTAILOR: A software program that lets you add or remove optional OpenVMS files from your system disk.
