Parameter

log_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.

  • "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

Examples:

set session log_file_size="default"


set session log_file_size=10M

(warning) Minimum LOG File size is 64K, maximum is 1G. Setting size less then 64K effectively makes the LOG File unlimited.

log_rotation_period

Parameterlog_rotation_period
TypeText string
Value
  • "default" - default value, 7 days. This values is used even if the "log_rotation_period" is not specified.
  • "daily" or "1"
  • "weekly" or "7"
  • "never" or "0"
  • <N> - in N days

If the rotation log mode is enabled this parameter controls switching to next log file based on period of time passed. If enabled the switching to next log file appears at midnight.

Examples:

set session log_rotation_period="weekly"


set session log_rotation_period=14

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 a 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 re-scanned 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.

license_id

Parameter

license_id

TypeText string
Value

A set of license identifiers that specifies the licenses to be used by CHARON. This parameter is applicable only to licenses on which Stromasys placed restrictions on what products can be combined on a single license key. Please contact your Stromasys representative or VAR for more information.

Example:

set session license_id = "2718281828,314159265"

If this parameter is set, Charon considers for validation only the available licenses with license ID parameter set and equal to one of the license ID's specified in the configuration. This prioritized list corresponds to the "Product License Number" line in the Product section of the license.

license_key_lookup_retry

Parameterlicense_key_lookup_retry
TypeText String
Value

In case the CHARON-AXP license connection is not present when the guest starts up, this parameter specifies how many times CHARON-AXP will try to establish the connection and, optionally, a period of time between retries.

Syntax:

set session license_key_lookup_retry = "N [, T]"

Options:

  • N - Number of retries to look for license keys.
  • T - Time between retries in seconds. If not specified 60 seconds are used

Example 1

set session license_key_lookup_retry = 1

If license key is not found during initial scan, do only one more attempt after 60 seconds.

Example 2

set session license_key_lookup_retry = "1,30"

Same as above but retry in 30 seconds.

Example 3

set session license_key_lookup_retry = "3,10"

If license key is not found during initial scan, do 3 more attempts waiting 10 seconds between them.

Example 4

set session license_key_lookup_retry = "5"

If license key is not found during the initial scan, do 5 more attempts waiting 60 seconds between them.

affinity

Parameteraffinity
TypeText string
Value

Overrides any initial process affinity mask provided by the host operating system. Once specified it binds the running instance of the emulator to particular host CPUs.

Used for soft partitioning of the host CPU resources and/or for isolating host CPUs for other applications.

By default the CHARON-AXP emulator instance allocates as many host CPUs as possible. The “affinity” parameter overrides that and allows explicit specification on which host CPU the instance must run on.


Note

The "affinity" parameter defines the total number of host CPUs to be used both for emulated Alpha CPUs and for CHARON-AXP application itself (including the CPUs to be used for I/O - they are controlled by "n_of_io_cpus" parameter described below).

Host CPUs are enumerated as a comma separated list of host system assigned CPU numbers:

set session affinity="0, 2, 4, 6"
