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 a NonStop S-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 extents. 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.
