3 bos_setrestart - Sets when the BOS Server restarts processes
10 B<bos setrestart> S<<< B<-server> <I<machine name>> >>>

22 The B<bos setrestart> command records in the F</usr/afs/local/BosConfig>
23 file the times at which the BOS Server running on the server machine named
24 by the B<-server> argument performs two types of restarts:
30 A I<general restart>. The BOS Server will restart itself,
31 and then any AFS process marked with the C<Run> status flag in the
32 F<BosConfig> file (equivalent in effect to issuing the B<bos restart>
33 command with the B<-bosserver> flag) at this time each week. By default,
34 in a new bos installation, general restarts are disabled.
38 A I<binary restart>. By default, once per day the BOS Server restarts any
39 currently running process for which the timestamp on the binary file in
40 the F</usr/afs/bin> directory is later than the time the process last
41 started or restarted. The default is 5:00 a.m. each day.
47 Restarting a process makes it unavailable for a period of time. The B<fs>
48 process has potentially the longest outage, depending on how many volumes
49 the file server machine houses (the File Server and Volume Server reattach
50 each volume when they restart). The default settings are designed to
51 coincide with periods of low usage, so that the restarts disturb the
52 smallest possible number of users.
54 If the setting specified with the B<-time> argument is within one hour of
55 the current time, the BOS Server does not restart any processes until the
56 next applicable opportunity (the next day for binary restarts, or the next
57 week for general restarts).
59 The command changes only one type of restart setting at a time; issue the
60 command twice to change both settings.
66 =item B<-server> <I<machine name>>
68 Indicates the server machine on which to set a new restart time. Identify
69 the machine by IP address or its host name (either fully-qualified or
70 abbreviated unambiguously). For details, see L<bos(8)>.
72 =item B<-time> <I<time to restart server>>
74 Specifies the restart time. By convention the general restart is defined
75 as weekly (specifies both a day and a time), and the binary restart is
76 defined as daily (specifies only a time). However, it is acceptable to
77 define a daily general restart or weekly binary restart.
79 There are four acceptable values for either type of restart setting:
85 The string C<never>, which directs the BOS Server never to perform the
86 indicated type of restart.
90 The string C<now>, which directs the BOS Server to perform the restart
91 immediately and never again.
95 A time of day (the conventional type of value for the binary restart
96 time). Separate the hours and minutes with a colon (I<hh:MM>), an use
97 either 24-hour format, or a value in the range from C<1:00> through
98 C<12:59> with the addition of C<am> or C<pm>. For example, both C<14:30>
99 and C<"2:30 pm"> indicate 2:30 in the afternoon. Surround this parameter
100 with double quotes (C<"">) if it contains a space.
104 A day of the week and time of day, separated by a space and surrounded
105 with double quotes (C<"">). This is the conventional type of value for the
106 general restart. For the day, provide either the whole name or the first
107 three letters, all in lowercase letters (C<sunday> or C<sun>, C<thursday>
108 or C<thu>, and so on). For the time, use the same format as when
109 specifying the time alone.
113 If desired, precede a time or day and time definition with the string
114 C<every> or C<at>. These words do not change the meaning, but possibly
115 make the output of the B<bos getrestart> command easier to understand.
119 Sets the general restart time.
123 Sets the binary restart time.
125 =item B<-cell> <I<cell name>>
127 Names the cell in which to run the command. Do not combine this argument
128 with the B<-localauth> flag. For more details, see L<bos(8)>.
132 Assigns the unprivileged identity C<anonymous> to the issuer. Do not
133 combine this flag with the B<-localauth> flag. For more details, see
138 Constructs a server ticket using a key from the local
139 F</usr/afs/etc/KeyFile> or F</usr/afs/etc/KeyFileExt> file.
140 The B<bos> command interpreter presents the
141 ticket to the BOS Server during mutual authentication. Do not combine this
142 flag with the B<-cell> or B<-noauth> options. For more details, see
147 Prints the online help for this command. All other valid options are
154 The following command sets the general restart time on the machine
155 C<fs4.example.com> to Saturday at 3:30 am.
157 % bos setrestart -server fs4.example.com -time "sat 3:30" -general
159 The following command sets the binary restart time on the machine
160 C<fs6.example.com> to 11:45 pm.
162 % bos setrestart -server fs6.example.com -time 23:45 -newbinary
