exrecover daemon

IBM recommends that this environment variable be set by a system
administrator as opposed to a user setting it for their environment. If the
latter occurs and the user sets the TMP_VI directory to something different
than what exrecover recognizes as TMP_VI, the user will need to run the
exrecover daemon manually to allow the temporary files to be converted to
the recoverable files used by vi (located in /etc/recover/$LOGNAME).
Note: A system administrator should NOT set TMP_VI to
/etc/recover/$LOGNAME. Also, the administrator should not set
TMP_VI to any directory where a pathname component is an
environment variable with a user’s value different than the
initialization process’s value (for example, $HOME). vi temporary
files are converted into a form recoverable by vi when exrecover is
run during IPL. Since exrecover is issued during IPL, it is owned by
the initialization process and will therefore contain different values for
certain environment variables, if those environment variables are set.
Throughout the file system, there may exist some temporary files
that can only be converted by exrecover. This conversion can be
done manually by a system administrator (to recover files owned by
all users) or by a single user (to recover only their own files).
TMPDIR
The default directory. When this environment variable is set, exrecover
looks in this directory for the ex and vi working files.
TMP If TMPDIR is not set, TMP specifies the directory to be searched when
looking for the ex and vi working files.
If both TMPDIR and TMP are not set, exrecover uses the directory that the C/C++
Run-Time Library function tempnam() would use.
exrecover uses the following localization environment variables:
v LANG
v LC_ALL
v LC_MESSAGES
v NLSPATH
See Appendix F for more information.
exrecover uses the following files:
/tmp/VIl*
Line table files.
/tmp/VIn*
Name files.
/tmp/VIt*
Paged text files.
/etc/recover
The directory containing subdirectories of user names whose files have
been recovered. Only users with the appropriate privileges, such as the
system administrator, can create the /etc/recover directory.
/etc/recover/$LOGNAME/VIn*
Contains the name of the file that was being edited.
