Virtual Alpha 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="AlphaServer_ES40"

Available models are:

Name of the CHARON VM (it must be unique):

set session configuration_name="MSCDV1"

  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 VM 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).

It is strictly recommended to use the "configuration_name" parameter if more than one CHARON VM runs on the same server.

• "all" (default)
• "info"
• "warning"
• "error"

Defines the message types to be shown. The parameter is a string of comma delimited words.

Example:

set session log_show_messages="error, warning"

log_file_size

If log rotation is enabled, the log_file_size parameter determines the log file size threshold at which a new log is automatically created. 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 

  • M - Megabyte

  • G - Gigabyte

Example 1:

set session log_file_size="default"

Example 2:

set session log_file_size=10M

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

• "default" - default value, 7 days. This value is used even if the "log_rotation_period" is not specified.
• "daily" or "1"
• "weekly" or "7"
• "never"
• <N> - in N days where N is greater than 0

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

Example 1:

set session log_rotation_period="weekly"

Example 2:

set session log_rotation_period=14

Specifies if repeated messages should be filtered or not. Possible values are "on" and "off" (default).

If the value is "on", immediately following messages with the same identifier and system error code are not listed in the log but they are counted. When a different log message is generated, the repeat count of the earlier log message is reported with the entry "The previous message has been repeated N times." and the counter is cleared.

Stromasys highly recommends to let this value to "off" otherwise important information will not be reported in the log file.

Example:

set session log_repeat_filter="off"

• <period-in-seconds>

Defines a period of flushing log to disk.

Default period is 60 seconds (it means that every minute log file is flushed to disk)

Examples:

set session log_flush_period=30

license_key_id

license_id

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.

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.

Limits the number of emulated CPUs.

Example:

set session n_of_cpus=3

The maximum number of CPUs enabled by CHARON VM is specified by the license key. It cannot exceed the original hardware restrictions. See table below.
