Parameterconfiguration_name
TypeText string
Value

Name of CHARON-VAX instance (unique):

set session configuration_name="MSCDV1"

The value of this parameter is used as prefix to the event log file name when multiple log files are configured (see below).

From the example above, the CHARON-VAX log file will have the following name:

MSCDV1-YYYY-MM-DD-hh-mm-ss-xxxxxxxxx.log

xxxxxxxxx is an increasing decimal number starting from 000000000 to separate log files with the same time of creation (in case the log is being written faster than one log file per second).

log

Parameterlog
TypeText string
Value

The log file or directory name is where the log file for each CHARON-VAX execution session is stored.

titleLog specified as a file name

It is possible to overwrite the existing log file or to extend it using the "36802882952452log_method" parameter.

(info) The "log_method" parameter is effective only when a single log file is specified, not a directory.

Example:

set session log="/charon/vax4106prod.log"

titleLog specified as a directory

CHARON-VAX automatically creates individual log files for each CHARON-VAX execution session. If the log parameter is omitted, CHARON-VAX creates a log file for each CHARON-VAX execution session in the directory where the emulator was started. In these two cases, the log rotation mode is enabled, meaning a new log file is created each time the virtual machine is started and when the log file size exceeds the one specified (see 36802882952452 log_file_size) and/or when the log file is older than a specified number of days (see 36802882952452 log_rotation_period).

(info) A symbolic link located in the same directory will be created, pointing to the active log file. Its name is based on the hw_model parameter or the configuration_name parameter if specified.

If the "configuration_name" parameter of the session is specified, the log file name is composed as follows:

<configuration_name>-YYYY-MM-DD-hh-mm-ss-xxxxxxxxx.log

If the "configuration_name" parameter is omitted, the log file name will have the following format:

<hw_model>-YYYY-MM-DD-hh-mm-ss-xxxxxxxxx.log

where "xxxxxxxxx" is an increasing decimal integer, starting from 000000000 to separate log files with the same time of creation (in case the log is being created faster than one log file per second).

(warning) Only existing directory can be specified. If the directory specified does not exist, this will be considered as a flat file.

Example:

set session configuration_name="vax4106prod"

set session log="/charon/logs"

The execution of the virtual machine will create a log file, named /charon/logs/vax4106prod-2016-10-13-10-00-00-000000000.log (for example) and a symbolic link named /charon/logs/vax4106prod.log pointing to this file. The link will be updated when the log rotation will occur.

log_method

Parameterlog_method
TypeText string
Value
  • "overwrite" (default)
  • "append"

Determines if previous log information is maintained.

Info
This parameter must be specified only in addition to “log” parameter on the same line.

This parameter is applicable only if the CHARON-VAX log is stored in a file that is specified explicitly with the "log" parameter.

Example:

set session log="log.txt" log_method="append"


log_file_size

Parameter

license_key_id

TypeText string
Value

A set of Sentinel Key IDs that specifies the license keys to be used by CHARON. It is also possibly to use a keyword "any" to force CHARON to look for suilable suitable license in all available keys if the license is not found in the specified keys.

Example:

set session license_key_id = "1877752571,354850588,any"

Based on the presence of this parameter in the configuration file, CHARON behaves as follows:
 

  1. No keys are specified (the parameter is absent)
    CHARON performs an unqualified search for any suitable key in unspecified order. If no key is found, CHARON exits.

  2. One or many keys are specified
    CHARON performs a qualified search for a regular license key in the specified order. If it is not found, CHARON exits (if the keyword "any" is not set).

If the keyword "any" is specified then if no valid license has been found in the keys with specified ID’s all other available keys are examined for valid license as well.

Note

The order in which keys are specified is very important. If a valid license was found in the key which ID was not the first one specified in configuration file, then available keys are periodically rescanned and if the key with the ID earlier in the list than the current one is found CHARON tries to find a valid license there and in case of success switches to that key.
