condor_on

Start up Condor daemons

Synopsis

condor_on [-help -version]

condor_on [-debug] [-pool centralmanagerhostname[:portnumber]] [-name hostname hostname -addr "a.b.c.d:port" "a.b.c.d:port" -constraint expression -all ] [-daemon daemonname]

Description

condor_on starts up a set of the Condor daemons on a set of machines. This command assumes that the condor_master is already running on the machine. If this is not the case, condor_on will fail complaining that it cannot find the address of the master. The command condor_on with no arguments or with the -daemon master option will tell the condor_master to start up the Condor daemons specified in the configuration variable DAEMON_LIST. If a daemon other than the condor_master is specified with the -daemon option, condor_on starts up only that daemon.

This command cannot be used to start up the condor_master daemon.

For security purposes (authentication and authorization), this command requires an administrator's level of access. See section 3.6.1 on page  for further explanation.

Options

-help

Display usage information

-version

Display version information

-debug

Causes debugging information to be sent to stderr, based on the value of the configuration variable TOOL_DEBUG

-pool centralmanagerhostname[:portnumber]

Specify a pool by giving the central manager's host name and an optional port number

-name hostname

Send the command to a machine identified by hostname

hostname

Send the command to a machine identified by hostname

-addr "a.b.c.d:port"

Send the command to a machine's master located at "a.b.c.d:port"

"a.b.c.d:port"

Send the command to a machine located at "a.b.c.d:port"

-constraint expression

Apply this command only to machines matching the given ClassAd expression

-all

Send the command to all machines in the pool

-daemon daemonname

Send the command to the named daemon. Without this option, the command is sent to the condor_master daemon.

Exit Status

condor_on will exit with a status value of 0 (zero) upon success, and it will exit with the value 1 (one) upon failure.

Examples

To begin running all daemons (other than condor_master) given in the configuration variable DAEMON_LIST on the local host:

% condor_on

To start up only the condor_negotiator on two named machines:

% condor_on  robin cardinal -daemon negotiator

To start up only a daemon within a pool of machines other than the local pool, use the -pool option. The argument is the name of the central manager for the pool. Note that one or more machines within the pool must be specified as the targets for the command. This command starts up only the condor_schedd daemon on the single machine named cae17 within the pool of machines that has condor.cae.wisc.edu as its central manager:

% condor_on -pool condor.cae.wisc.edu -name cae17 -daemon schedd
