Usage: jobscheduler_agent.cmd command [options] command: start [options] stop [options] abort [options] restart [options] status [options] debug [options] kill [options] install-service [options] remove-service [options] start-service [options] options: -http-port=<number> | default: 4445 -timeout=<number> | in seconds; only for stop and restart |
Start the Agent
...
Command Line Options
...
-http-port=<number>
- is the HTTP port that the Agent is listening to in order to receive requests from a JobScheduler Master:
jobscheduler_agent.cmd|sh
...
command -http-port=####
- where
####
is the numeric port.
- Without this option being used the port defaults to 4445.
- Should you want to specify a port then the following precedence applies:
- First precedence: command line option
- Second precedence: environment variable
SCHEDULER_HTTP_PORT (see below)
- Third precedence: use of default value
-timeout=<number>
- This option
Stop the Agent
Code Block | ||
---|---|---|
| ||
jobscheduler_agent.cmd|sh stop [options] |
This command will safely terminate the Agent (recommended).
- The Agent waits for running processes to be completed.
- The
-timeout=<number>
option- can be used to specify the number of seconds that the Agent will wait for tasks to stop.
- This option can be applied for
stop
andrestart
commands. - The Agent sends a SIGTERM signal to the taksk and having reached the timeout a SIGKILL signal will be sent to stop any tasks immediately.
- Any child processes will be killed by the Agent.

- Log File
- On startup the Agent creates a log file in the directory that is pointed to by the environment variable
SCHEDULER_LOG_DIR
or in thelogs
subdirectory of the Agent installation directory. - Log file names are created from a prefix and the port used by the Agent like this:
jobscheduler_agent_4445.log
- Log files are rotated for each day and are kept for one week (see ./
lib/log4j.xml
). - Rotated log files get the name of the form
jobscheduler_agent_4445.log.<yyyy-MM-dd>
- On startup the Agent creates a log file in the directory that is pointed to by the environment variable
- PID File
- On startup the Agent creates a PID file in the directory that is pointed to by the environment variable
SCHEDULER_PID_FILE_DIR
or in the log directory. The PID file contains the Process ID of the system process that the Agent is running in. - The PID file is used in order to prevent the Agent to be started twice with the same settings and it can be used for shutdown scripts that require the PID to terminate the process.
- Pid PID file names are created from a prefix and from the port used by the Agent like this:
jobscheduler_agent_4445.pid
- On startup the Agent creates a PID file in the directory that is pointed to by the environment variable
Command Line Options
- The only available option is the http port that the Agent is listening to in order to receive requests from a JobScheduler Master:
jobscheduler_agent.cmd|sh command -http-port=####
- where
####
is the numeric port.
- Without this option being used the port defaults to 4445.
- Should you want to specify a port then the following precedence applies:
- First precedence: command line option
- Second precedence: environment variable
SCHEDULER_HTTP_PORT
- Third precedence: use of default value
Environment Variables
The following environment variables can be used:
Environment Variables
The following environment variables can be used:
JAVA_HOME
- points to the location of the Java Runtime Environment (JRE).
- Without setting this environment variable Java will be used from the location specified by the system path.
- Please consider that
JAVA_HOME
does not point to the location of a JDK but to a JRE directory where thebin/java
executable resides.
SCHEDULER_HOME
- points to the directory where the JobScheduler Agent has been installed
JAVA_HOME
- points to the location of the Java Runtime Environment (JRE).
- Without setting this environment variable Java will be used from the location specified by the system path.
- Please consider that
JAVA_HOME
does not point to the location of a JDK but to a JRE directory where thebin/java
executable resides.
SCHEDULER_HOME
- the default value is the parent directory of the start script.
- Should you want to start the Agent from a directory
- points to the directory where the JobScheduler Agent has been installed.
- Without setting this environment variable the default value is the parent directory of the start script.
- Should you want to start the Agent from a directory different to the Agent installation directory, e.g. by copying the start script to some other location, then this environment variable has to be set in order to locate the JobScheduler Agent installation directory.
SCHEDULER_HTTP_PORT
- sets the port that the JobScheduler Agent is listening to.
- Without setting this environment variable the port defaults to 4445.
SCHEDULER_USER
- sets the user account that the JobScheduler Agent is operated for. This includes running jobs with the permissions of the specified user.
- This setting is available for Unix systems only. For Windows systems the user account that runs the start script is used.
- Without setting this environment variable the user acount that runs the start script is used.
- This setting can be used when running the Agent start script in system start-up and shutdown configurations that are executed by
root
, e.g. in/etc/init.d
or corresponding locations.
SCHEDULER_LOG_DIR
- sets the directory where the JobScheduler Agent log file is created.
- This setting defaults to the directory
logs
in the Agent installation directory. - For Windows systems for which the Agent is installed in the program directory that is pointed to by the
%ProgramFiles%
environment variable it is recommended not to use the default setting. Instead specify a different path via theSCHEDULER_LOG_DIR
environment variable, e.g. some location in the data directory that is pointed to by the%ProgramData%
environment variable.
SCHEDULER_PID_FILE_DIR
- sets the directory where the JobScheduler Agent pid file is created.
- This setting defaults to the directory that is specified with the
SCHEDULER_LOG_DIR
environment variable or the log directory default value.
...
- Multiple instances of the JobScheduler Agent on the same computer can be operated, e.g. for different user accounts that jobs should be executed for.
- Any number of Agent instances can be started from the same installation, however, different ports have to be used that the Agent is listening to for requests of a JobScheduler Master.
- Running the Agent for different user accounts and ports
- Use the environment variable
SCHEDULER_USER
to operate the Agent for a user account that is different from the one that starts the Agent. - Use the environment variable
SCHEDULER_HTTP_PORT
or the option-http-port=####
to start the Agent for a port that is different from the default setting. - Make sure that the directories
SCHEDULER_LOG_DIR
andSCHEDULER_LOG_DIR
andSCHEDULER_PID_FILE_DIR
are readable and writable for the different user accounts
- Use the environment variable
Add the startup options as given in the following examples to your individual startup script.
...
_PID_FILE_DIR
are readable and writable for the different user accounts
Add the startup options as given in the following examples to your individual startup script.

Process Class and Standalone Job
First create a Process Class, for example the following (find attached example: agent1.process_class.xml):
...
Second, you should define a Standalone Job and associate the Process Class defined above to the Job job (find an example attached: standalone_hello.job.xml):
