NAME

       pbs_server - start a pbs batch server

SYNOPSIS

       pbs_server [-a    active]    [-d config_path] [-p port]    [-A acctfile]    [-L logfile]    [-M mom_port]
       [-R momRPP_port] [-S scheduler_port] [-H hostname] [-t type]

DESCRIPTION

       The pbs_server command starts the operation of a batch server on the local host.  Typically, this command
       will be in a local boot file such as /etc/rc.local .  If  the  batch  server  is  already  in  execution,
       pbs_server will exit with an error.  To insure that the pbs_server command is not runnable by the general
       user community, the server will only execute if its real and effective uid is zero.

       The  server  will  record a diagnostic message in a log file for any error occurrence.  The log files are
       maintained in the server_logs directory below the home directory of the server.  If the log  file  cannot
       be opened, the diagnostic message is written to the system console.

OPTIONS

-a active Specifies if scheduling is active or not. This sets the server attribute scheduling. If
the option argument is "true" ("True", "t", "T", or "1"), the server is active and the PBS
job scheduler will be called. If the argument is "false" ("False", "f", "F", or "0), the
server is idle, and the scheduler will not be called and no jobs will be run. If this
option is not specified, the server will retain the prior value of the scheduling
attribute.

-d config_path Specifies the path of the directory which is home to the servers configuration files,
PBS_HOME. A host may have multiple servers. Each server must have a different
configuration directory. The default configuration directory is given by the symbol
$PBS_SERVER_HOME which is typically /usr/spool/PBS.

-p port Specifies the port number on which the server will listen for batch requests. If multiple
servers are running on a single host, each must have its own unique port number. This
option is for use in testing with multiple batch systems on a single host.

-A acctfile Specifies an absolute path name of the file to use as the accounting file. If not
specified, the file is named for the current date in the PBS_HOME/server_priv/accounting
directory.

-l scheduler_port
Specifies the host name and port number of listening schedulers. By default pbs_server
communicates to the scheduler on the loop back address at port 15004. If the scheduler and
pbs_server are not on the same host the -l option tells pbs_server where to find the
scheduler. When using TORQUE in high availability mode the -l option should be used to
let TORQUE know where all potential schedulers are located. If pbs_server and the
scheduler are not on the same node the -l option or the -S option must be used in order
for TORQUE to communicate with the scheduler.

-L logfile Specifies an absolute path name of the file to use as the log file. If not specified, the
file is one named for the current date in the PBS_HOME/server_logs directory, see the -d
option.

-M mom_port Specifies the host name and/or port number on which the server should connect the job
executor, MOM. The option argument, mom_conn, is one of the forms: host_name,
[:]port_number, or host_name:port_number. If host_name not specified, the local host is
assumed. If port_number is not specified, the default port is assumed. See the -M
option for pbs_mom(8).

-R mom_RPPport Specifies the port number on which the the server should query the up/down status of Mom.
See the -R option for pbs_mom(8).

-S scheduler_port
Specifies the port number to which the server should connect when contacting the
Scheduler. By default pbs_server looks for the scheduler on the loopback address at port
15004. The -S option changes the default to the value given in the option argument. The
option argument, scheduler_conn, is of the same syntax as under the -M option.

-H hostname Causes the server to start under a different hostname as obtained from gethostname(2).
Useful for servers with multiple network interfaces to support connections from clients
over an interface that has a hostname assigned that differs from the one that is returned
by gethostname(2).

-t type Specifies the impact on jobs which were in execution, running, when the server shut down.
If the running job is not rerunnable or restartable from a checkpoint image, the job is
aborted. If the job is rerunnable or restartable, then the actions described below are
taken. When the type argument is:

hot All jobs are requeued except non-rerunnable jobs that were executing. Any
rerunnable job which was executing when the server went down will be run
immediately. This returns the server to the same state as when it went down.
After those jobs are restarted, then normal scheduling takes place for all
remaining queued jobs.

If a job cannot be restarted immediately because of a missing resource, such as a
node being down, the server will attempt to restart it periodically for upto 5
minutes. After that period, the server will revert to a normal state, as if warm
started, and will no longer attempt to restart any remaining jobs which were
running prior to the shutdown.

warm All rerunnable jobs which were running when the server went down are requeued.
All other jobs are maintained. New selections are made for which jobs are placed
into execution. Warm is the default if -t is not specified.

cold All jobs are deleted. Positive confirmation is required before this direction is
accepted.

create The server will discard any existing configuration files, queues and jobs, and
initialize configuration files to the default values. The server is idled.

FILES

       $PBS_SERVER_HOME/server_priv
                      default directory for configuration files, typically /usr/spool/pbs/server_priv

       $PBS_SERVER_HOME/server_logs
                      directory for log files recorded by the server.

Signal Handling

       On receipt of the following signals, the server performs the defined action:

       SIGHUP The current server log and accounting log are closed and reopened.  This allows for the prior  log
              to be renamed and a new log started from the time of the signal.

       SIGINT Causes an orderly shutdown of pbs_server.

       SIGUSR1, SIGUSR2
              Causes server to increase and decrease logging levels, respectively.

       SIGTERM
              Causes an orderly shutdown of pbs_server.

       SIGSHUTDN
              On systems (Unicos) where SIGSHUTDN is defined, it also causes an orderly shutdown of the server.

       SIGPIPE
              This signal is ignored.

       All other signals have their default behavior installed.

EXIT STATUS

       If the server command fails to begin batch operation, the server exits with a value greater than zero.
