HP OpenVMS Version 8.4 for Integrity and Alpha servers SPD 82.35.19
Class Scheduler for CPU Scheduling
The Class Scheduler is a SYSMAN-based interface for
defining and controlling scheduling classes for Open-
VMS systems that allows you to designate the percent-
age of CPU time that a system’s user may receive by
placing users into scheduling classes.
Batch and Print Queuing System
OpenVMS provides an extensive batch and print capa-
bility that allows the creation of queues and the setup of
spooled devices to process non-interactive workloads in
parallel with timesharing or real-time jobs.
The OpenVMS batch and print operations support two
types of queues: generic queues and execution queues.
A generic queue is an intermediate queue that holds a
job until an appropriate execution queue becomes avail-
able to initiate the job. An execution queue is a queue
through which the job (either print or batch) is actually
processed. Because multiple execution queues can be
associated with a generic queue, OpenVMS enables
load balancing across available systems in an Open-
VMS Cluster system, increasing overall system through-
put.
Print queues, both generic and execution, together with
queue management facilities, provide versatile print ca-
pabilities, including support for various print file formats.
Accounting Utility
For accounting purposes, OpenVMS keeps records of
system resource usage. These statistics include pro-
cessor and memory utilization, I/O counts, print sym-
biont line counts, image activation counts, and process
termination records. The OpenVMS Accounting utility
allows you to generate various reports using this data.
Audit Analysis Utility
For security auditing purposes, OpenVMS selectively
records critical, security-relevant events in the system
security audit log file. These records contain the date
and time the event occurred, the identity of the asso-
ciated user process, and information specific to each
event type. This information helps the system manager
maintain system security and deter possible intruders.
The OpenVMS Audit Analysis utility allows you to gen-
erate various reports from this data.
Autoconfigure and AUTOGEN Utilities
The Autoconfigure and AUTOGEN utilities automatically
configure the available devices in the system tables and
set system parameters based on the peripheral and
memory architecture. This eliminates the need for a tra-
ditional system generation process when the hardware
configuration is expanded or otherwise modified.
The OpenVMS AUTOGEN command procedure sets
several system parameters automatically by detecting
the devices installed in a configuration. A feedback op-
tion allows you to generate a report of recommended
parameter settings based on previous usage patterns.
Backup Utility
The Backup utility provides both full-volume and incre-
mental file backups for file-structured, mounted volumes
and volume sets. Individual files, selected directory
structures, or all files on a volume set can be backed
up and restored. Files can be selected by various dates
(such as creation or modification) and can be backed up
to magnetic tape, magnetic disk, or Write Once Read
Many (WORM) optical disk. The Backup utility can also
be used to restore a saveset or list the contents of a
saveset.
The Backup utility has been extended to support volume
up to 2 TiB. Backup utility has also been enhanced to
create and restore a compressed save set. The com-
pressed save set can be created on disks and magnetic
tapes. The compression ratio depends on the data con-
tent in the files.
A Backup API is included for invoking backup routines
from an executable procedure.
The Backup Manager for OpenVMS provides a screen-
oriented interface to the Backup utility that assists users
in performing routine backup operations. The Backup
Manager is menu driven and provides:
• Access to the save, restore, and list operations with-
out having to understand Backup command syntax
• The ability to create, modify, recall, and delete
Backup Manager templates that describe the Backup
save operations
Recordable DVD
OpenVMS provides the capability on Alpha and Integrity
server systems to record locally mastered disk volumes
or disk image files onto a CD-R, CD-RW, DVD+R or
DVD+RW optical-media recording device on specific
drives and configurations.
Recordable CD
OpenVMS provides the capability to write once to CD-R
media using an application shipping in the base oper-
ating system. The feature supports only those writable
CD devices (CD-RW) that ship with supported Alpha
systems and supported Integrity servers. For the ap-
plication details, see the OpenVMS documentation set.
For platforms supporting the CD-RW hardware option,
