The following table describes all available "session" parameters, their meaning and examples of their usage:

Div
classpagebreak


hw_model

Parameter

hw_model

Type

Text string, case sensitive

Value

Virtual VAX/PDP11 system hardware model to be emulated.

Use a default configuration template for each particular model as a starting point for a custom configuration. This would ensure that the parameter is set correctly.

Example:

set session hw_model="VAX_6610"

Available models are:

  • PDP_1193

  • PDP_1194
  • MicroVAX_3100_Model_96
  • MicroVAX_3100_Model_98
  • MicroVAX_3600
  • MicroVAX_3900
  • MicroVAX_II
  • VAXserver_3600
  • VAXserver_3600
  • VAXserver_3600_128
  • VAXserver_3600_512
  • VAXserver_3900
  • VAXserver_3900_128
  • VAXserver_3900_512
  • VAX_4000_Model_106
  • VAX_4000_Model_108
  • VAX_4000_Model_700
  • VAX_4000_Model_705
  • VAX_6000_Model_310
  • VAXstation_4000_Model_90
  • VAX_6610
  • VAX_6620
  • VAX_6630
  • VAX_6640
  • VAX_6650
  • VAX_6660

configuration_name

Parameter

configuration_name

Type

Text string

Value

Name of the Charon-VAX / Charon-PDP instance (it must be unique):

set session configuration_name="MSCDV1"

(warning)  In provided templates this parameter is specified in the included configuration file "configuration_name.icfg".

The value of this parameter is used as a prefix to the event log file name (see below).

From the example above, the Charon-VAX / Charon-PDP 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).

(warning) It is strictly recommended to use the "configuration_name" parameter if more than one Charon instance runs on the same server.

log

Parameterlog
TypeText string
Value

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

Panel
borderColor#3AAADC
bgColor#FFFFFF
titleColor#FFFFFF
titleBGColor#3AAADC
titleLog specified as a file name

It is possible to overwrite the existing log file or to extend it using the "log_method695730385" parameter.

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

Example:

set session log="C:\Charon\vax4106prod.log"


Panel
borderColor#0062AB
bgColor#FFFFFF
titleColor#FFFFFF
titleBGColor#0062AB
titleLog specified as a directory

Charon-VAX / Charon-PDP automatically creates individual log files for each Charon-VAX / Charon-PDP execution session. If the log parameter is omitted, Charon-VAX / Charon-PDP creates a log file for each Charon-VAX / Charon-PDP 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 log_file_size695730385) and/or when the log file is older than a specified number of days (see log_rotation_period695730385).

(info) A shortcut 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. No trailing backslash character is allowed.

Example:

set session configuration_name="vax4106prod"

set session log="C:\Charon\Logs"

The execution of the virtual machine will create a log file, named C:\Charon\Logs\vax4106prod-2016-10-13-10-00-00-000000000.log (for example) and a shortcut named C:\Charon\Logs\vax4106prod.log pointing to this file. The shortcut will be updated when the log rotation will occur.

(info) Starting with version 4.11 build 204-11, log file numbering is implemented when log rotating is used: when starting the Charon emulator the first log file name will be like <configuration_name>-YYYY-MM-DD-hh-mm-ss-xxxxxxxxx.log where xxxxxxxxx will be 000000000, this number will increase with each log rotation to make it easier to find a log file set (1st log file at start + all its rotated files)

Parameterlog_file_size
TypeText string
Value

If log rotation is enabled, the log_file_size parameter determines the log file size threshold at which the log is automatically rotated. Rotating log file size is multiple of 64K

  • "unlimited" or "0" (default) - the feature is disabled
  • "default" - default size is used (4Mb)
  • <size>[KMG] - size of the current log file in bytes with additional multipliers:

    • K - Kilobyte - multiply by 1024

    • M - Megabyte - multiply by 1024*1024

    • G - Gigabyte - multiply by 1024*1024*1024

Example 1:

set session log_file_size="default"

Example 2:

set session log_file_size=10M

(info) Minimum LOG File size is 64K, maximum is 1G. Setting a size less than 64K effectively makes the log file size unlimited.
