Charon-PAR Command-Line Options

Please note: each instance of Charon-PAR must be started in a separate directory because certain files (SSTORAGE.DAT, NVOLATILE.DAT, UA_SSTORAGE.DAT, and console.dat) will always be created in the current working directory of the emulator instance. Starting multiple emulator instances in the same directory will lead to errors due to file locking problems.

When starting Charon-PAR (the command /opt/charon/bin/charon-par), there are several command-line options that can be used. The following table provides an overview:

Option	Description
`-G <mode>` `--ditgcsync <mode>`	Do not use in a production environment unless instructed to do so by Stromasys technical support! Possible values: sync: synchronous garbage collector mode async: asynchronous garbage collector mode (default)
`-S <mode>` `--ditsync <mode>`	Do not use in a production environment unless instructed to do so by Stromasys technical support! Possible values: sync: synchronous DIT execution mode async: asynchronous DIT execution mode (default) no_dit: DIT disabled
`-K <dit-level>--dit-kind <dit-level>`	Do not use in a production environment unless instructed to do so by Stromasys technical support! Each Charon-PAR model has a built-in maximal DIT optimization level. This parameter allows to reduce this level. As result, the emulation will run with reduced performance. Possible values (from lowest to highest): dispatch, slow, medium, basic, adv
`-X <mode>` `--collect-statistics <mode>`	Collect the available statistics. Mode format: `<level>,json,<file-name>`, where level = 0-9
`-a` <name> `--instance-name` <name>	Assigns a logical name to the emulated system instance at start. This parameter will only be used in future Baremetal environments.
`-c` <console-port> `--console-port` <console-port>	Redirects the Charon-PAR console to a TCP/IP port that can be accessed via telnet (from local system only). This makes the console accessible also when the emulator runs in daemon mode. The port number can be in the range of 0-65535. However, port numbers 0-1023 are generally reserved for specific applications and should not be used.
`-f` `<filename>``--config` `<filename>`	Specifies the path to the emulator configuration file.
`-h--help`	Displays a short help information.
`-l` <logpath> `--logfile-path` <logpath>	Specifies the path to the logfile.
`-p <filename>` `--pidfile <filename>`	Name of file to store the process ID of the emulator process. Used mostly when running emulator as a daemon.
`-x` `--daemon`	The emulator is started as a daemon. This mode can be used when the emulator is to be started at system boot. It can also be used to start the emulator while connected to the system via the network to avoid license problems.
