NonStop Operations Guide for H-Series and J-Series RVUs

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 NonStop system. 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, see “Related Reading for Tools and Utilities”
(page 227).
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.
CLIMCMD
The CLIMCMD mechanism executes CLIM commands from the NonStop host system TACL.
CLIMCONFIG
The climconfig command is used to configure network resources on a CLIM. It works in much the
same way that SCF SUBNET configuration works in other NonStop TCP/IP products.
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.
