Command Line Options
--http-port
- Specifies the HTTP port that the Agent is listening to in order to receive requests from a JS7 Controller. This option can be used to indicate which network interface the JS7 Agent should listen to if a hostname or IP address is specified, for example with
--http-port=myhost:4445
. - Without this option being used the port defaults to
4445
and the Agent listens to all available network interfaces. - If a port is specified then the following order of precedence applies:
- First precedence: command line option
- Second precedence: environment variable
JS7_AGENT_HTTP_PORT
(see below) - Third precedence: use of default value
- Specifies the HTTP port that the Agent is listening to in order to receive requests from a JS7 Controller. This option can be used to indicate which network interface the JS7 Agent should listen to if a hostname or IP address is specified, for example with

--
httphttps-port=myhost:4445
.- When using the HTTPS protocol for connections from a Controller instance consider additionally allowing the HTTP protocol for local connections as with
--http-port=localhost:4445
. As the Agent Start Script makes use of an HTTP connection the protocol has to be in place to allow the Agent to be started, stopped, etc. by its Start Script. - Without this option being used the port defaults to
4445
and the Agent listens to all available network interfaces. - If a port is specified then the following order of precedence applies:

--sigkill-delay
- Specifies the delay for terminating job processes on Unix in case the Agent is terminated. A value

- When using JS7 - systemd Service Files for automated Startup and Shutdown with Unix Systems users should consider that
--timeout
and--sigkill-delay
values will count towards the systemd service file'sTimeoutStopSec
setting. Users must ensure that the Agent is terminated when the systemd timeout is exceeded. - The option is available for Agents running on Unix starting from release 2.7.2, see

Switches
-c , -job-java-options=<java options>
- This option can be used to specify Java options for Shell jobs that load a JVM. This option does not apply to jobs derived from JS7 - Job Templates that are executed in the Agent's JVM.
- In order to specify a number of Java options quotes have to be used like this:

- Specifies that the
curl
utility should be used instead of the built-in HTTP client when sending commands to the Agent.
--sigkill
- Starting from release 2.7.2 the switch is ignored.
Watchdog Script agent_watchdog.sh, agent_watchdog.cmd
Technically the Agent is started and is restarted from its Watchdog Script, for details see JS7 - Agent Watchdog.
The Watchdog Script is used to terminate job processes and child processes in case that the Agent is crashed.
Instance Instance Start Script: agent_<port>.sh, agent_<port>.cmd
...
It is recommended that an individual Instance Start Script is created from the template file as this allows to specify individual start-up parameters to specified using from environment variables.
Location
...
When used for Container operation using Unix OS then the following command is used:
Code Block | ||
---|---|---|
| ||
agent_4445.sh|.cmd start-container [options] |
This The command is used to start the JS7 Agent in a container:
- The command will keep the start script running as PID 1 in order to receive later stop/kill signals ( SIGTERM, SIGKILL ) signals from the container management software.
- The command
start-docker
is an alias forstart-container

This command will terminate the Agent.
- Unix
- Job processes and child processes will be terminated and the Agent will terminate with exit code 0.
- collect PIDs of job processes,
- send SIGTERM signal to remaining job processes and child processes for which PIDs have been collected,
- wait for the grace timeout specified with the job or for stdout/stderr to be released by processes whichever is earlier,

- Windows
- Job processes and child processes will be forcibly terminated and the Agent will terminate with exit code 0.
- Using the
--timeout
option will wait for the indicated timeout that the Agent terminates. If the timeout is exceeded and if the Agent is still running, then Agent and jobs will be focibly terminated. The option accepts a number of seconds or thenever

# terminate jobs on Unix by sending SIGKILL with a delay of 10s and restart Agent agent_4445.sh|.cmd kill [options] |
The Agent process is killed.
- This corresponds to sending a SIGKILL signal with a

command (Unix) ortaskkill
command (Windows). - Should jobs be running that start detached child processes then it is not guaranteed that child processes will be killed.
Restarting the Agent

The command will restart the Agent.
- Job processes and child processes will be terminated and the Agent will terminate as explained in chapter Stopping the Agent.
- The Agent is started similar to use of the
start
command using the same options as for initial start. - The
--timeout
option for Unix/Windows and the--sigkill-delay

Debugging the Windows Service
- For general information see JS7 - Log Levels and Debug Options.
- The log level can be increased by using the Agent's Apache ProcRun Daemon Service Manager daemon/service.On On Windows systems this is installed in the Agent's
service
folder directory with a name such as asjs7_agent_<port>w.exe
where<port>
is the Agent's HTTP port. - Users can start the ProcRun Manager, select the Logging tab in the user interface and set the log level to Debug.
- The For the location of log files is explained above. see JS7 - Log Files and Locations.
- Users should consider reverting the debug log level to its original value once they are finished with debugging.
