Administrating a LysKOM site
============================
For lyskomd 1.9.0
This document is a short description of how to administrate a LysKOM
database on your site.
The first thing you will have to do is to follow the instructions in
the file INSTALL. This will set up the LysKOM system with a database
containing a few necessary conferences and one person - the
administrator.
Once the LysKOM system is running, there is not much you will have
to do to keep it that way. One thing to remember is that the current
release of the server has an incomplete handling of garbage collection
of the database. The database is split into two files, the
information file and the text file. Newly written texts are
concatenated to the text file and old texts are never removed. The
information file contains information about conferences, users and
where in the text file the texts are. This file is properly garbage
collected, but not the text file.
There is a program called dbck (Data Base Check) which is used to
check the consistency of the LysKOM database. This program can also
be used to shrink the text file. To do this, just type `dbck -g' in
the database directory, or give additional switches to dbck to use the
correct directory. See further the manual page for dbck. When dbck
is to be run on the database, the LysKOM server *must* be stopped, or
unrepairable damage may result. See below for a description on how to
stop the server.
There is a program called updateLysKOM which is used to ensure
continuous operation. This program is run with certain intervals and
if the LysKOM server has died for some reason, updateLysKOM restarts
it. If the server is still running properly, updateLysKOM sends a
signal (SIGUSR1) to it, which causes the server to write some
statistics to a file named etc/lyskomd-log in the lyskom directory.
Taking the server down cleanly can be done in two ways: through the
use of the LysKOM protocol on a socket, preferably through the use of
a suitable client, or by sending the signal SIGHUP to it. This will
cause the server to save the database and close all client
connections. It will also create a file named etc/memory-usage in
which the memory usage of the server is reported.
To prevent updateLysKOM from restarting a server, create a file
named /usr/lyskom/etc/status. The file should contain a valid mail
address on the first line. UpdateLysKOM will not restart the server
as long as that file exists. In addition, if the file is between 1
and 2 hours old an email will be sent to the mail address found in the
file. If the file is older than that, an error message will be
printed on stderr and updateLysKOM will exit with a non-zero exit
status. cron is expected to deliver the error message to an operator.
The shell script komrunning can be used to start and stop the LysKOM
server. With no arguments, it will report the status.
komrunning off
will shut down the server, creating the file /usr/lyskom/etc/status,
while
komrunning on
will restart it. The actual stopping and starting of the server will
be done by updateLysKOM the next time it is run. komrunning only
creates the lock file.
