8.12 Increasing Free Space on the System Disk
If quotas are not in use on the system disk, ignore the "No such file" message for
QUOTA.SYS. Most inconsistencies (including "marked for delete") can be repaired
by entering the following command:
$ ANALYZE /DISK_STRUCTURE /REPAIR SYS$SYSDEVICE:
8.12.2 Using VMSTAILOR and DECW$TAILOR
To remove files you do not need from the system disk, use VMSTAILOR. For
example, if you are not running DECnet for OpenVMS, you do not need the
network support files. For complete information about using VMSTAILOR to
remove files, see Chapter 10.
If you are running DECwindows Motif, use DECW$TAILOR to add or remove
DECwindows base support, workstation support, and fonts.
Note
Files installed on alternate devices cannot be tailored.
8.12.3 Purging System Files
In most cases, you can purge the following OpenVMS system files to free space on
your system disk. However, before you purge any of these files, read Appendix F
to make sure you do not purge a file version you might want to keep.
SYS$SYSTEM:SHUTDOWN.COM
SYS$SYSTEM:STARTUP.COM
SYS$LIBRARY:ENCRYPSHR.EXE
SYS$LIBRARY:*RTL*.EXE
SYS$LIBRARY:*SHR.EXE
SYS$MANAGER:EDTINI.EDT
SYS$MANAGER:DBLSTRTUP.COM
SYS$MANAGER:*.TEMPLATE
SYS$EXAMPLES:XADRIVER.MAR
SYS$LIBRARY:CDDSHR.EXE
SYS$LIBRARY:EPC$FACILITY.TLB
SYS$MESSAGE:EPC$MSG.EXE
SYS$STARTUP:VMS$LAYERED.DAT
To purge a file, enter the PURGE command followed by the file specification. For
example:
$ PURGE SYS$SYSTEM:SHUTDOWN.COM
8.13 Restoring Your System Password Dictionary
The OpenVMS VAX operating system screens potential passwords for
acceptability. The DCL command SET PASSWORD takes the user’s proposed
password, converts it to lowercase (if necessary), and compares it to entries in
a system dictionary. If the proposed password is found in the dictionary, it is
rejected as a valid user password, and the user must suggest another. Many
system managers modify the system password dictionary to include words of
significance to their site.
During the upgrade, the procedure replaces the existing system password
dictionary with a new one. If you had modified the dictionary and want to restore
your local additions, you must merge the file containing your additions with the
new system file.
