Appendix D
Removing Unwanted VMS Files
D.1 Using VMSTAILOR
Read this appendix if you want to remove the VMS operating system and
DECwindows files that you do not need from the system disk. For example,
if you are not running DECnet–VAX, you do not need the network support
files. You can remove unwanted files with the VMSTAILOR program. Enter
the following command to log in to the SYSTEM account:
$ RUN SYS$UPDATE:VMSTAILOR
Return
The VMSTAILOR program asks you if you want to tailor files ON or OFF.
Enter OFF to remove unwanted files.
CAUTION: Do not delete files from the factory-installed software (FIS)
system until you have backed up your software. A VMS distribution
kit is needed to return files to the system disk. Also, VMSTAILOR and
DECW$TAILOR procedures cannot restore files from a backup set. It may
be necessary to reload the system software from a backup set if files are
incorrectly deleted and if a VMS distribution kit is not available.
The VMSTAILOR program lists each group of files and its size in blocks.
Files are grouped according to their function. For example, all the files
required for cluster support are in one group. A file group is made up of
many small subgroups. You can eliminate an entire group of files or you
can eliminate one or more of its subgroups.
Decide which file groups or subgroups you do not need to support your
system. The VMSTAILOR program displays step-by-step instructions that
are easy to follow.
VMSTAILOR displays the names of the files it deletes. After it finishes,
AUTOGEN runs automatically to make the adjustments that are necessary
after system files are deleted.
NOTE: You can use VMSTAILOR at any time to delete or add groups of
VMS files to the system disk. After adding files to the system disk, you
should apply any updates that affect them.
