<P>Traces Volume Location Server operations
|

|
|
<P><STRONG>Description</STRONG>
|
||
|
|
<P>The <B>VLLog</B> file records a trace of Volume Location (VL) Server
|
||
|
|
(<B>vlserver</B> process) operations on the local machine and describes
|
||
|
|
any error conditions it encounters.
|
||
|
|
<P>If the <B>VLLog</B> file does not already exist in the
|
||
|
|
<B>/usr/afs/logs</B> directory when the VL Server starts, the server
|
||
|
|
process creates it and writes initial start-up messages to it. If there
|
||
|
|
is an existing file, the VL Server renames it to <B>VLLog.old</B>,
|
||
|
|
overwriting the existing <B>VLLog.old</B> file if it exists.
|
||
|
|
<P>The file is in ASCII format. Administrators listed in the
|
||
|
|
<B>/usr/afs/etc/UserList</B> file can use the <B>bos getlog</B>
|
||
|
|
command to display its contents. Alternatively, log onto the server
|
||
|
|
machine and use a text editor or a file display command such as the UNIX
|
||
|
|
<B>cat</B> command. By default, the mode bits on the
|
||
|
|
<B>VLLog</B> file grant the required <B>r</B> (<B>read</B>)
|
||
|
|
permission to all users.
|
||
|
|
<P>The VL Server records operations only as it completes them, and cannot
|
||
|
|
recover from failures by reviewing the file. The log contents are
|
||
|
|
useful for administrative evaluation of process failures and other
|
||
|
|
problems.
|
||
|
|
<P>The VL Server can record messages at three levels of detail. By
|
||
|
|
default, it records only very rudimentary messages. To increase logging
|
||
|
|
to the first level of detail, issue the following command while logged onto
|
||
|
|
the database server machine as the local superuser <B>root</B>.
|
||
|
|
<PRE> # <B>kill -TSTP</B> <VAR>vlserver_pid</VAR>
|
||
|
|
|
||
|
|
</PRE>
|
||
|
|
<P>where <VAR>vlserver_pid</VAR> is the process ID of the <B>vlserver</B>
|
||
|
|
process, as reported in the output from the standard UNIX <B>ps</B>
|
||
|
|
command. To increase to the second and third levels of detail, repeat
|
||
|
|
the command.
|
||
|
|
<P>To disable logging, issue the following command.
|
||
|
|
<PRE>
|
||
|
|
# <B>kill -HUP</B> <VAR>vlserver_pid</VAR>
|
||
|
|
|
||
|
|
</PRE>
|
||
|
|
<P>To decrease the level of logging, first completely disable it and then
|
||
|
|
issue the <B>kill -TSTP</B> command as many times as necessary to reach
|
||
|
|
the desired level.
