NonStop NS-Series Operations Guide (H06.12+)

B Tools and Utilities for Operations
When to Use This Appendix
This appendix briefly describes the tools and utilities that might be available on your system to
assist you in performing the operations tasks for an Integrity NonStop NS-series server. The use
of some of these tools and utilities is discussed throughout this guide. For a list of other
documentation that provides detailed information about these tools and utilities, refer to
Appendix C, Related Reading.
BACKCOPY
Use the BACKCOPY utility to create one or two duplicate tapes for archive storage, distribution,
or disaster recovery. You can also create one or two labeled (or unlabeled) tape sets from a labeled
or unlabeled tape set. The BACKCOPY utility duplicates tapes that are made from a BACKUP
utility file-mode operation, but it cannot duplicate tapes that are made from a BACKUP utility
volume-mode operation.
BACKUP
Use the BACKUP utility to copy files from disk to magnetic tape.
Disk Compression Program (DCOM)
The Disk Compression Program (DCOM) moves disk-file extents to yield more usable space on
a disk. Use the DCOM utility to analyze the current space allocation on a disk, relocate file extents
on a disk, and reduce the number of free-space fragments. You can also combine free space into
larger extents so that files can be allocated with larger extents, which decreases the incidence of
file-system error 43 (unable to obtain disk space for file extent).
Disk Space Analysis Program (DSAP)
The Disk Space Analysis Program (DSAP) analyzes how disk space is used on a specified volume.
The DSAP utility copies the disk directory and free-space table to the current work file. By
specifying options, you can manipulate this data to produce several different reports about the
use of the disk space for that volume. The free-space table is limited only by your primary (main)
and secondary (contiguous disk space) memory requirements.
EMSDIST
The EMSDIST program is the object program for a printing, forwarding, or consumer distributor,
any of which you can start with a TACL RUN command.
Event Management Service Analyzer (EMSA)
Use the Event Management Service Analyzer (EMSA) to extract specific types of event messages
from EMS log files and to create an Enscribe database that you can query to analyze problem
trends.
File Utility Program (FUP)
The File Utility Program (FUP) is a component of the standard software package for the NonStop
Kernel operating system. FUP software is designed to help you manage disk files, nondisk devices
(printers, terminals, and tape drives), and processes (running programs) on the Integrity NonStop
system. You can use FUP to create, display, and duplicate files; load data into files; alter file
characteristics; and purge files.
