Configuration Settings

Engine has the ability to configure settings for a tenant, package, or registration. The listing of settings below will note the most specific level at which a particular setting may be configured. This is not a complete listing of the available configuration settings, though it does include everything we expect new customers might want to change.

A level of "special", "base", or "system" indicates a setting that must be set system-wide, and will apply to all tenants. The difference between them is the possible methods of configuring a value for the setting. Settings marked "base" or "special" can only be configured in the settings file mentioned below. Those marked "system" can be configured either in the properties file or through the API.

Your Engine delivery includes a template for a settings file used to configure values you want to apply system-wide. The configuration file (RusticiEngineSettings.config) should be referenced by your web.config file in the appSettings section.The configuration file (RusticiEngineSettings.properties) should be placed in your application server's classpath.

Settings Reference

Each setting is defined as follows:

SettingIdentifier (level [, default: defaultValue])

description of setting

The level is the most specific level at which the setting may be configured. Settings may always be configured at a lower (less specific) level, If a setting is configured at multiple levels, the most specific level will be used.

From less specific to most, the levels are:

• system (including base and special)
• tenant
• package
• dispatch destination
• dispatch
• registration

Note: Engine strives to have sensible defaults for all settings, so generally you do not need to configure a value for the majority of those listed here. If you aren't sure if you should be changing a particular setting or not, or what you should set it to, please reach out and ask us.

xAPI Settings

xAPIEnabled

xAPIRewriteStatementModifier

If rusticiRewrite=true is passed on the statements request, then this setting will be used to modify statements as they are returned. It is expected to be a JSON object with an 'overlay' and/or a 'knownRegistrationOverlay' property. These overlays, from each configuration level (eg: system, tenant, and registration) will be merged into any statements read from this tenant (the knownRegistrationOverlay will only be applied to statements for which the registration can be looked up). The ID for the statement will be changed and the original ID will be noted in an extension property. See 'Dynamic Setting Values'

xAPIMaxRequestSizeInBytes

The maximum number of bytes to accept in an xAPI request before returning an error. The default is 5 mebibytes.

xAPIObjectStoreRepairs

Some customers who upgraded to Engine 2015.1 from earlier versions of Engine and were using xAPI may experience bugs arising from the keys in the upgraded object store not matching the scheme used in 2015.1 and later. Setting this allows customers to fix this issue by automatically searching for certain objects based on the location they would have had in 2014. The valid choices here are UriHashCase and DocumentHashCase. Both options should be enabled for Java customers with this problem; only UriHashCase is necessary for .NET customers. In both cases, be sure to consult with Engine support before enabling, so we can confirm this problem applies to you.

xAPIEnablePublicEndpoint

If set, allows unauthenticated access to a public xAPI endpoint.

xAPILaunchTokenLifeInSeconds

Sets the initial life of the TinCan Launch Token. This time is only set when the token is first created. Default is 8 hours.

xAPILaunchTokenUpdateLifeInSeconds

Sets the updated life of the TinCan Launch Token. This time will be added to the expiry every time the token is accessed. Default is 0.

xAPILaunchTokenCleanupIntervalInSeconds

How long to wait between each execution of the background task that cleans up expired xAPI launch tokens. Default is 2 hours.

UsePlayerForTinCanLaunches

Sets whether Tin Can launches should use Engine's player rather than launching the course directly.

AllowWritableUserAgentProfile

Allow launched cmi5 or Tin Can content to write to the user agent profile of the learner associated with the course launch.

CharsToNonRandomizeUuid

How many characters from the start of some uuids should be set in deterministic way to improve clustering. The maximum allowed value is 6 and a value between 2 and 4 is recommended

IntervalInSecondsPerGroupingOfUuids

Sets the length of interval used to normalize some uuids. For example if set to 600, the ids created during that period of 600s (10 minutes) would start with the same characters, with the amount of characters used determined by 'CharsToNonRandomizeUuid'

LRS Settings

SystemHomepageUrl

The absolute URL of the canonical, permanent, homepage for this system. Ideally this really is the homepage a user would use to access the system, but this must be canonical and permanent: that is, it is a single URL the system can be identified by. This setting is required for xAPI, in order to create actor objects for users in the system. It is also used to construct activity IDs during SCORM to xAPI conversion.

xAPIFilesPath

This setting is a fallback for both xAPILargeDocumentsPath and xAPILargeAttachmentsPath. If those settings are not given, this setting will be used instead.

xAPILargeDocumentsPath

The root path or file store (see file stores) where large xAPI documents will be stored (see xAPIMaxDocumentSizeForDatabaseInBytes to define "large").

xAPILargeAttachmentsPath

The root path or file store (see file stores) where large xAPI attachments will be stored (see xAPIMaxDocumentSizeForDatabaseInBytes to define "large").

HashContentFilesForActivityId

Specifies whether or not non-xAPI content files should be hashed to generate an activity ID during import. If true, then all of the files in the content directory are hashed to generate the activity ID. If false, then only the manifest file is hashed.

xAPIValidations

xAPI validations that are required to pass the conformance test (and indeed to conform to xAPI), but were not present in prior releases of Engine. These should be left on if possible, but are provided as a setting to enable non-conforming requests to work if needed. To disable all xAPI validations, use the value "none".

xAPIPostProcessContextParameters

Only relevant if TinCanPostProcessContext is overriden, or as a way to consume extraneous parameters so they are not flagged as 'unexpected'. Comma-delimited, case sensitive list of xAPI parameters to pass to the TinCanPostProcessContext integration method requestParameters collection. This is needed because xAPI requires us to consider any unexpected parameters an error, so if an integration uses parameters from the xAPI call it needs to declare that usage. The default value contains extra parameters the combination of the Engine player and the TinCan launch process recomendation typically cause to be sent.

EnableExistingActivityIdParserWarnings

When enabled (default), parser warnings will be generated during import of packages with activities that are either already mapped to a package, or recorderd in the LRS.

xAPIMaxSizeForDatabaseInBytes

Setting that determines the max number of bytes to put into a DB for a document or attachment before trying to store the document in a file store (see xAPILargeDocumentsPath and xAPILargeAttachmentsPath). Unfortunately, documents and attachments stored in the database must be kept entirely in memory, and so it is advantageous to put larger documents and attachments in the filestore, which supports streaming (low memory usage).

xAPIUrlPrefix

The URL prefix that is used for xAPI requests.

xAPIUrl

The full URL that is used for xAPI requests. If the value is not specified, a default value of {RusticiEngineUrl}/{xAPIUrlPrefix}/ will be used. Note: xAPI requests will fail if xAPIUrl does not contain /{xAPIUrlPrefix}/

LrsAuth Settings

LrsAuthCallbackMaxCacheSize

The number of cache entries at which to obliterate the auth callback cache to prevent excessive memory usage.

LrsAuthCallbackUrl

Call back URL that will provide basic auth authorization. Will convert username:password@hostname to basic authentication if provided.

LrsAuthCacheSecondsSuccess

The default amount of time to cache a successful LRS auth callback. Can be overridden via auth callback response for each individual request if necessary

LrsAuthCacheSecondsFailure

The default amount of time to cache an unsuccessful LRS auth callback. This value acts as a timeout that will prevent multiple quick requests (eg, DoS) to the callback page should there be an issue connecting or getting a response.

xAPIBasicAccounts

A set of xAPI accounts can be optionally specified. To use one of these accounts, the same username and password must be sent over HTTP basic auth to the xAPI endpoint. These should be separated by newlines, and must be of the form username:password:role. A bcrypt password hash may be used for the password portion. The roles are as follows:
* user : typical, default permissions, allowing the account to assert any statement, and read only those statements they have asserted or play some role in
* read-only : allowed to read all statements and state documents, but not write anything
* write-only : allowed to write any statement or xAPI document, but not read anything
* root : allowed to read and write any statement or xAPI document

API Settings

ApiAlternateIdDelimiter

A delimiter that may be used instead of | when passing External IDs to API calls, since | can be a problem in URL paths.

ApiRoot

The root path (under the main application path) for the API (before the API version).

NancyConsolePassword

Password for the Nancy Diagnostic Console (/RusticiEngine/_Nancy). Leave blank to disable. (.NET only)

ApiImportResultsPostBackUrl

Specifies a URL to which to post import results, will convert username:password@hostname to basic authentication if provided. You can use the value 'noop' to disable postbacks configured at a lower level (e.g., disable postbacks for a single tenant when a value has been configured at the system level for everyone).

ApiPostbackProcessorSleepSeconds

How long to sleep between checking for postback tasks to retry (note: the first try is always immediate, either by being synchronous or by triggering an async check of the queue.)

ApiResultLimit

Maximum number of items to return in a list at once.

ApiResultLimitSinceNotSpecified

Maximum number of items to return in a list at once when the 'since' parameter is available and not used. The only reason since is not a required parameter is to make testing the API easy, and long lists are not required for that.

ApiDoNotCheckAuthentication

For use when API authentication will be handled by a proxy or other software outside of Engine. All API calls will be allowed, IsAllowed() will not be called.

ApiEnableV2

Is the v2 API enabled? If false requests to the v2 API will be rejected regardless of the credential specified.

ApiIndentJson

Format the JSON returned from the API nicely, useful when developing but should usually be turned off in production for performance and payload size reasons.

ApiBasicSystemAccounts

A set of basic auth "accounts" comprising different API users for the system. The setting takes the form of `username:password[:role]` (the role is optional). A bcrypt password hash may be used for the password portion. At this moment, the only valid role is `root`.

ApiBasicTenantAccounts

A set of basic auth "accounts" comprising different API users for a particular tenant. The setting takes the form of `username:password[:role]`, where the role is optional. At this moment, the only valid role is `tenant`.

ApiTokenSecret

Secret used to sign tokens generated by the API, currently used in signed launch links. If the string starts with '0x' the remainder will be interpreted as hexidecimal.

PreviousApiTokenSecret

The previous ApiTokenSecret used to allow ApiTokenSecret rotation. Tokens previously built with it can continue to be validated, but it will not be used when creating new tokens.

ApiTokenPostbackValidHours

Number of hours the token used to authenticate SCORM runtime postbacks (when using signed launch links) is valid.

ApiUseSignedLaunchLinks

If enabled, launch links generated by the API will be signed, and only signed launch links will be accepted by the player (so launch links must be generated via the API).

ImportLinkLocation

The path to the import page used when you have generated an import URL to POST to.

DefaultImportRedirectLocation

Default redirect URL to redirect to after import via `defaultui\import` page if none was supplied.

JobTimeoutSeconds

The number of seconds until a `RUNNING` job is marked `TIMEOUT`.

ApiPingCheckDatabase

Determines whether a simple connectivity check of the Engine database should occur in the execution of the /ping resource.

ApiCourseDeleteAttemptDeleteFiles

Controls whether or not deleting a course through the API should also attempt to delete the course's files. This functionality will only work for courses that are located within the FilePathToContentRoot that you have configured. It will not delete the metadata files for remote AICC or Tin Can courses.

ApiMaxAuthTokenLifetimeSeconds

Maximum amount of seconds from now an API token expiration may be set to, when creating a token. Note: there is no way to invalidate individual tokens besides waiting for them to expire, so be careful with long lived tokens.

WebHookAuthConfiguration

Configuration for WebHookAuth plugin. See Integrating With Engine / Web Hooks in documentation

WebHookCustomUserAgent

Custom user agent header to set for web hook requests.

SystemWebHookAdditionalHeaders

Additional headers which will be added to web hook requests which are not associated with a tenant, or for which a tenant override isn't set. Comma delimited list in the format of 'headerName:value'

TenantWebHookAdditionalHeaders

Additional headers which will be added to web hook requests for a given tenant. If this is not set for a given tenant, or if the request is not tied to any tenant, the list from 'SystemWebHookAdditionHeaders' will be used. If this is set for a given tenant, this list overrides the list in 'SystemWebHookAdditionalHeaders'. Comma delimited list in the format of 'headerName:value'

WebHookLoggedMessageBodyMaxLength

When a web hook failure is logged, the logged MessageBody should be truncated to what length? A value of "0" will not show the MessageBody.

SubscriptionClientCertificatePath

Client Certificate to be used by subscription event notifications

SubscriptionClientCertificatePassword

Password for the Client Certificate used by subscription event notifications

ApiRollup Settings

ApiRollupRegistrationPostBackUrl

Specifies a URL to which to post activity and status data within an interval in which dirty data is available or as soon as possible when the course is completed. You can use the value 'noop' to disable postbacks configured at a lower level (e.g., disable postbacks for a single tenant when a postback url has been configured at the system level).

ApiRollupRegistrationSynchronous

The initial attempt to post registration data will occur synchronously as the course is being completed.

ApiRollupRegistrationAuthType

Indicates how to authorize against the given postbackurl, can be 'form' or 'httpbasic'. If form authentication, the username and password for authentication are submitted as form fields 'username' and 'password', and the registration data as the form field 'data'. If httpbasic authentication is used, the username and password are placed in the standard Authorization HTTP header, and the registration data is the body of the message. This field is set to 'httpbasic' by default.

ApiRollupRegistrationAuthUser

User name to use when posting registration data.

ApiRollupRegistrationAuthPassword

Password to use when posting registration data.

ApiRollupRegistrationFormat

Level of detail in the information that provided when posting registration data. It may be one of three values: 'course' (course summary), 'activity' (activity summary, or 'full' (full detail), and is set to 'activity' by default. The information will be posted as JSON, using the schemas for the registration /progress or /progress/detail resources depending on the format selected, with an additional wrapper specifying the registration ID.

ApiPostbackTimeoutSeconds

Timeout in seconds for API rollup registration postback.

ApiRollupRegistrationDuringSession

Should rollup registration postbacks be sent during a learning session, instead of waiting for the learner to exit?.

Database Settings

SystemDatabaseEnabled

Should the system database be used? Note: if disabled, features that use system wide queues such as PENS and xAPI pipes will not work. Multiple tenants per DB are not supported without a system database. This setting must be set as desired upon initial installation of Engine, changing it on a existing system is likely to result in data loss.

UseSystemDatabaseForTenantSettings

Should the system database be used to store tenant settings (other than the connection string)? Note: if disabled, setting tenant settings other than connection string will fail until a valid connection string is configured for the tenant.

SystemDatabaseConnectionString

The connection string to use when connecting to the system schema

DatabaseSchema

The DBMS-level schema to use when connecting to the database. At this moment, it is not possible to specify different tenant and system DBMS schemas.

TenantDatabaseConnectionString

The connection string to use when connecting to the tenant schema. For customers using multiple tenant DBs, this should be set to NOT_CONFIGURED in your configuration file.

TenantDatabaseReadReplicaConnectionString

The connection string to use when connecting to the read replica for a tenant schema.

ReadReplicaMaximumExpectedLagMS

The expected maximum expected amount of lag time before the read replica reflects updates. Used to set X-Experience-API-Consistent-Through, and may be used in a future version of Engine to determine what other reads may be safely serviced via the replica.

DataPersistenceEngine

A string (`sqlserver`, `mysql`, `postgresql`, or `oracle`) corresponding to the DBMS flavor in use.

DatabaseTimeoutSeconds

The timeout (in seconds) to set on database operations. This setting applies only to .NET.

DatabaseRetryCount

The number of retries we should attempt an database action when contending for shared locks.

MaxPersistableStringLength

The maximum string length (in characters) to allow through to the database.

TenantIdLength

The length, in bytes, of the tenancy field in the database

StoreRuntimeDataAsLob

Determines whether runtime data received from player should be stored in a lob column or normalized.

UseNativePostgreSqlUpserts

By default, Engine will use the INSERT / ON CONFLICT upserts for PostgreSQL databases instead of first trying to insert and then updating if there's a conflict. Must be using PostgreSQL 9.5+ to use this setting. To disable the behavior for older versions of PostgreSQL, set this value to false.

Upsert Settings

MaxRowsPerDatabaseUpsert

The maximum number of rows we should send in a single datbase upsert (merge) statement. Set to 0 for no limit.

MaxUpsertSizeInBytes

The maximum size of each upsert (merge) statement in bytes. Set to 0 for no size limit. This setting is usually only necessary for MySQL customers with a very small max_allowed_packet value.

MaxParametersPerDatabaseUpsert

The maximum number of parameters to include in a single database upsert/merge statement. Set to 0 for no limit. The default of 2100 is based on limits inherent to SqlServer.

AttemptInsertBeforeUpsert

If true, attempt to use inserts before upserts. This can result in a signficant performance gain in systems where inserts would generally be expected to succeed, such as the Engine upgrade tool. The use of this setting is not supported with PostgreSQL and can result in errors.

Tenancy Settings

TenancyEnabled

AllTenantNames

List of tenants for when Engine needs to iterate over all tenants in a systemless installation.

TenantSettingSyntaxEnabled

Enable tenant setting prefix syntax (tenantName.settingId) for configuring tenant specific settings in the configuration file. Disabling this when not in use can save memory on systems with a large number of tenants.

ProxiedRequests Settings

ForwardedHost

The original (before proxying) value of the "Host" header field in Engine requests (i.e. the targeted host of a request at its origin). As with the "Host" HTTP header, this value may come with a port number appended.

ForwardedProtocol

The original (before proxying) protocl used to send requests to Engine. If the Engine server is behind an SSL Offloading proxy, this value will likely be HTTPS.

Encryption Settings

EncryptionPassword

This setting gives the secret key used for encryption of configuration settings, and xAPI pipe passwords. If this is set to a 128 bit value expressed as hex in the format '0xABCD...', it will be used as the encryption key. If not, it will be used to generate a key, which will introduce a small delay the first time the key is needed.

PreviousEncryptionPassword

For use when changing passwords. Set this to the prior value of EncryptionPassword so values encrypted with it can continue to be decrypted until encrypted with the new password.  Note: for fallback to a previous password to work, the Encryptor must detect and throw an exception when decryption fails.

Encryptor

An implementation of RusticiSoftware.ScormContentPlayer.Logic.Encryption.IEncryptor to be used for encryption and decryption of configuration settings and/or external IDs.

PreviousEncryptor

The previously used implementation of RusticiSoftware.ScormContentPlayer.Logic.Encryption.IEncryptor used, so values encrypted with it can continue to be decrypted until encrypted with the new encryptor. Note: for fallback to a previous encryptor to work, the main Encryptor must detect and throw an exception when decryption fails.

ConfigurationEncryptionExceptions

A comma delimited list of setting ids to encrypt or avoid encrypting, ignoring the default for that setting. Prefix settings to encrypt with '+' and settings to avoid encrypting with '-'.

EncryptConfigurationSettings

If true (and encryption passsword is specified), configuration settings of type 'secretString' will be encrypted.

HashAccountPasswords

If true then when storing configuration settings of type 'accounts', any passwords provided that are not bcrypt hashes will be converted to bcrypt hashes.

Misc Settings

Plugins

Comma separated list of implementation definitions that dictates which plugins are loaded by Engine if available. Plugins that are loaded by default can be disabled by listing the plugin preceded by '-' (i.e. '-ContentConnector.YouTube').

GenerateTinCanLaunchStatements

Specifies whether to generate and save 'launched' statements during Tin Can launches

TinCanInteractionsEnabled

If enabled, Engine will extract runtime interaction details from certain xAPI statements and include them in the progress data reported by the API and the registration postback (in 'full' format).

UseStatementTimestampInRegistrationUpdates

Normally the FirstAccessDate and CompletedDate values are set to the current time when the statement is processed and we update the registration state from it. This switches to using the timestamp value from the statement triggering the registration update for these values where applicable.

ValidateManifestsUsingXsd

Whether to additionally validate manifests using an XML parser as well as the Engine validation

SSPEnabled

Can be disabled if no content is ever going to use SSP. Marginal player performance may be perceived by doing so.

DefaultCommCommitFrequency

RusticiEngineUrl

Context path to which Engine has been deployed

WebPathToContentRoot

A web path (URL) pointing to the directory that is hosting your course content. If you're hosting the content on the same domain as Engine, then you can exclude the domain in your URL (i.e. "/path/to/content/root").

WebPathToContentRootHistory

A list of historical values used for WebPathToContentRoot, which allows the launch links of packages uploaded when these historical values were in effect to be updated so as to reflect the current value. These entries are not required to be in historical order.

ContentAuthCookieFactory

For generating cookies to allow access to content. Definition for an 'ICookieAuthFactory' implementation. Format: 'full.class.name|assembly.name, constuctorarg1, arg2, arg3' (assembly name is not needed for Java, or where class is in RusticiSoftware.Engine). Engine provides an implementation for Amazon CloudFront. Example for CloudFront authentication cookies that will expire in 8 hours: 'RusticiSoftware.ScormContentPlayer.Logic.Utilities.CloudFrontCookieFactory, /fullpath/to/privatekey.pem, keyPairId, 480'

SimpleQueueRetryInitialDelaySeconds

How long to mark tasks as ineligible for processing when picking them up. This time will be doubled after each retry.

SimpleQueueMaxRetries

How many times to attempt a queued item before giving up. Note that the last retry will have a delay of 2^(n-1) * SimpleQueueRetryInitialDelaySeconds

ApiPostbackProcessorMaxBatchSize

Maximum number of rollup registration tasks to dequeue for processing at once.

FilePathToContentRoot

The path to the directory or file store (see file stores) where uploaded and unzipped files should be placed.

FilePathToUploadedZippedPackage

The path or file store (see file stores) where uploaded zip files should be placed. In a future release this may be used to allow different Engine instances to receive an upload and process the import, but for now there is no reason this shouldn't just be set to a temporary directory on the local file system.

StorePlayerDebugLogsInFileStoreOnExit

Determines whether or not the player debug logs will be saved to the file store automatically when the player exits. With this setting set to true, if PlayerDebugLogsStorageLocation is set, then the player debug logs will be stored in the location configured by that setting.

PlayerDebugLogsStorageLocation

The path to the directory or file store (see file stores) where the player debug logs will be stored. If this setting is configured, then clicking 'Save Debug Log' in the debugger will save the player debug logs to this location.

RedirectOnExitUrlAcceptedRegex

This regex will be used to check the RedirectOnExitUrl values passed in the launch URL (not the RedirectOnExitUrl configuration value). If it passes, then the RedirectOnExitUrl value in the launch URL will be used to redirect the user on course exit. If it does not pass, then it uses the configuration value for RedirectOnExitUrl.

RedirectOnExitUrl

The URL the application should redirect to when the learner exits a course

DefaultModernPlayerTheme

(Deprecated) See 'ModernPlayerCustomizationStylesheetUrl'. The modern player theme to use unless otherwise specified in the launch URL.

RedactLogs

Redact personally identifiable information and credentials when logging.

SQLDebugLogMinimumExecutionMS

When DEBUG level loging is enabled so Engine's SQL statements are logged, only log statements that take at least this many milliseconds to execute.

RedactedItems

Comma delimited, case insensitive list of regular expressions (start and end anchors will be added) to match columns, configuration setting ids, or external ID class names to redact, if RedactLogs is enabled (otherwise this list has no effect).

UnRedactedColumns

Comma delimited, case insensitive list of regular expressions (start and end anchors will be added) to match columns that should NOT be redacted even though they appear in a table referenced in 'RedactedTables', if RedactLogs is enabled (otherwise this list has no effect).

RedactedTables

Comma delimited, case insensitive list of regular expressions (start and end anchors will be added) to match tables to redact (all columns that appear in one of these tables are redacted), if RedactLogs is enabled (otherwise this list has no effect).

WhenToRestartRegistration

Determines whether or not to restart a registration when launching it.

AllowedRequests

Comma delimited whitelist of non-API request types that are allowed (see documentation for SecureMethod enum for valid entries).

AiccSessionPerLaunch

If true, the AICC session ID will be created for each launch, and only valid until that launch session has terminated. Otherwise sessions will be precreated for a registration and valid as long as that registration exists.

UpdateRunTimeDataLockExpireSeconds

How many seconds to lock the registration for when updating SCORM runtime data. Specifying 0 disables registration locking.

UpdateRunTimeDataLockWaitSeconds

How long to wait for a lock on the registration when updating SCORM runtime data.

ManifestDirPathAcceptedRegex

This regex will be used to check the manifestDirPath in a preview launch. If the manifestDirPath matches this regex, then the manifest will be downloaded and validated. Otherwise preview launch will throw an exception. By default this setting is empty, meaning that nothing will be accepted and preview launch will always throw an exception.

Cmi5EntitlementKeyAlternate

Value to be provided to AUs in cmi5 `LMS.LaunchData` as the alternate entitlement key.

EnableRecordingMetrics

If true, Engine will record various metrics and enable an endpoint that exposes those metric values for reporting.

Cmi5RequireLearnerPreferencesReadBeforeInitialized

The cmi5 spec states, "On startup, the AU MUST retrieve the Learner Preferences document from the Agent Profile." disabling this setting will ignore that requirement.

EnforceStrictCmi5

If true, Engine will enforce cmi5 requirements strictly.

ApplicationInstanceId

A unique indentifier to be set on a particular instance of Engine, which is probably best done through an environment variable. Currently only used to refer to instances in the 'BackgroundProcessors' setting value.

BackgroundProcessors

Use this setting to list which background processors will run or not. A background processor will default to its particular setting unless explicitly stated as activated or deactivated. For the 'Instance' value, set and refer to a particular 'ApplicationInstanceId' setting or use 'All' to affect all instances.

BackgroundProcessorManagerSleepSeconds

The maximum interval of time at which Engine will check on its background processors.

Caching Settings

ExternalCacheConfiguration

Configuration for the external cache. For memcache this is a JSON object with a 'servers' property which is the list of cache servers to use in 'hostname:port' format, and 'timeoutMs' (default 2000) and `updateTimeoutMs` (default 4000) properties which are the timeouts in milliseconds for cache read/update requests respectively.

ExternalCacheKeyPrefix

Prefix for external cache keys to avoid collisions with other systems using the same cache. If multiple Engine installations will share a cache, each one should set this to a different value.

LocalCacheExpiryMilliSeconds

How long items may persist in the local cache, in milliseconds. For typical server farm installations, this should be how old a stale value it is acceptable to use, as cache invalidations will not propogate to local caches. Each entry is in cachedObject|milliseconds format, and default applies to any cached object without its own value. cachedObject|-1 indicates no expiration, which is only appropriate for single-server installations. CachedObject|0 disables the local cache for that object type. If a remote cache is in use, these values should probably be lowered until traffic to the remote cache becomes a bottleneck.

ExternalCacheExpiryMinutes

How long items may persist in the external cache, in minutes. Defaults to 10 days. This should generally be set to at least a day, as the only reason to expire external cache items is as a fallback in case an invalidation call fails. cachedObject|-1 indicates no expiration, cachedObject|0 disables the external cache for that object type.

LocalCacheDisableForLowFrequency

For installations with many Engine application servers (particularly with an external cache enabled) it may not be worth the memory usage or locks to store entries that are unlikely to be frequently used in a short time period. Enabling this setting disables the local cache by default for such items. Note that configuring a LocalCacheExpiryMilliSeconds entry for such an item will override this behavior.

LocalCacheMaxEntries

The maximum number of entries that will be retained in the local memory cache before items will be evicted (currently via TinyLFU on Java).

LocalCacheEnabled

Is the local cache enabled? Disabling the local cache is not recommended unless an extremely fast and reliable external cache is used.

Offline Settings

OfflineContentPathAcceptedRegex

This regex will be used to check the pathToContent parameter when exporting an offline course. If the pathToContent matches this regex, then the offline course will be exported, otherwise the export will throw an exception. By default this setting will deny all paths so is required if the pathToContent param is to be used. Note: 'AllowedRequests' must also be set to include 'OFFLINE_SERVICES' to allow exporting courses for offline use.

OfflinePathToContentRoot

Path to the directory or file store that is the root of where offline package content can be found.

OfflineZipOutputLocation

The path to the directory or file store (see file stores) where offline zip files should be placed.

ConcurrentLaunch Settings

ConcurrentLaunchDetectionEnabled

Enable or disable concurrent launch detection.

ConcurrentLaunchDetectionHistoryRows

The number of launch history entries to load when detecting concurrent launches.

ForceExitConcurrentLaunches

If true, force exit of previous launch without showing concurrent launch detected page.

LaunchHistoryExpiration Settings

ShouldExpireLaunchHistory

If true, purge old launch history entries. This can potentially save a lot of DBMS storage space.

ExpireLaunchHistoryAfterDays

The minimum number of days that should pass before purging a launch history entry.

xApiStatementPipe Settings

xAPIStatementPipeEnabled

If true, enable the statement pipe feature.

xAPIStatementPipeSleepTimeMilliseconds

When no pipes are ready to be processed, the statement pipe thread will sleep for this many milliseconds.

xAPIStatementPipeCooldownMilliseconds

The minimum amount of time, in milliseconds, that the statement pipe thread will wait to poll an endpoint for new statements after running out of new statements.

xAPIStatementPipeMaxBackoffHours

When piping statements, we may encounter an error when calling the API of either LRS. If we do, we retry after a set amount of time, that doubles with each successive failure. This value sets a maximum amount of time (in hours) we will wait between retries. If 0 is given, there is no maximum.

xAPIStatementPipeBatchSize

The maximum number of statements that we will send at a time when using the statement pipe feature.

xAPIStatementPipeWebTimeoutMilliseconds

The timeout, in milliseconds, we will use when sending GET and POST requests to the LRSes involved in a statement pipe. This number is set fairly high by default to accomodate batches involving many attachments.

xAPIStatementPipeLockTimeSeconds

The amount of time, in seconds, a given machine can lock a statement pipe for exclusive use. This value should encompass the 'clock drift' between machines and any delays due to possible slow connections or failed timeouts.

xAPIStatementPipeMaxAttempts

The maximum number of times a statement pipe can fail (in a row) before Engine stops trying. With default backoff settings, the time between attempts quickly approaches xAPIStatementPipeMaxBackoffHours. So with default settings, this is roughly the # of days Engine will try a failing pipe for. Saving the pipe configuration again (specifying either the source or target url) will reset the attempt count, and restart the pipe.

DeliverCustomization Settings

RemoteDeliverPageUrl

Web path (absolute or relative) location of the deliver HTML and player static files. Must be set to an absolute URL for LTI 1.3 platform support.

Note: As of version 21.1.7.219, there is a file, playerConfigurationUrl.json, in the /player folder that is deployed on the remote server. This will need to be modified to include the appropriate playerConfigurationUrl property value that points back to the PlayerConfiguration page in Engine (e.g., 'https://mydomain.com/RusticiEngine/PlayerConfiguration.jsp'). At runtime, for these remote deployments, Engine will retrieve this JSON file to determine what URL to use to retrieve the player configuration data.

RemoteDeliverPageUrlMap

Mapping of keys to urls formatted as 'key1|url1, key2|url2'. When a remoteUrlKey in additionalValues matches a key in this list, the URL specified in this list will be used instead of RemoteDeliverPageUrl for that launch.

Note: As of version 21.1.7.219, there is a file, playerConfigurationUrl.json, in the /player folder that is deployed on the remote server. This will need to be modified to include the appropriate playerConfigurationUrl property value that points back to the PlayerConfiguration page in Engine (e.g., 'https://mydomain.com/RusticiEngine/PlayerConfiguration.jsp'). At runtime, for these remote deployments, Engine will retrieve this JSON file to determine what URL to use to retrieve the player configuration data.

ModernPlayerCustomizationScriptUrl

Web path (absolute or relative) to a JavaScript file to load during modern player start up to allow for customization of player execution.

ModernPlayerCustomizationStylesheetUrl

Web path (absolute or relative) to a CSS file to load during modern player start up to allow for customization of player appearance.

PrivacyPolicyUrl

Web path (absolute or relative) that should be linked to as the privacy policy document.

IntermediatePageLoadAtStart

Whether to load the intermediate page in the content frame at launch before the loader takes over. Turning this off leads to a small performance optimization, but at the risk of the user not seeing a loading message particularly in multi SCO/AU courses with no automatic first SCO/AU load.

Player Settings

OriginTrialTokens

Comma separated list of origin trial tokens that you wish to use with Rustici Engine player.

ExitPlayerOnSingleScoClose

If set to 'false', the player will not exit and redirect on SCORM 'exit' or 'suspend all' requests. If the content window is closed, the player will behave more like a multi-sco course, and the learner can relaunch the sco from the navigation pane.

PlayerIsAvailableOffline

Specifies whether the package is available to take offline

RedirectOnRefreshUrl

Optional URL the application should redirect to when the learner refreshes the deliver page, which otherwise may result in a the content being re-launched. This can happen when the user deliberately refreshes the page, or uses the back button (except in IE where the back button just shows the existing page from cache and does not reload from the server, or re-run scripts)
Re-launch is a problem if the content was not suspended, as a new attempt will be generated which will not have all the details from the prior attempt (the prior attempt will still be shown in history).  So even though the user may have completed the initial attempt, they may appear to be incomplete.
This is an unusual problem, and frequently re-launching after a refresh is the best choice, so for now we only recommend assinging a value to this property if you have run into the problem described above.  The redirect page should minimally make it clear to the user how to get back into the content.

RedirectLaunchPageOnExit

When using any 'New Window' variant for PlayerLaunchType, if this setting is enabled, automatically returns the launch page to the LMS when the player window closes. This setting has no effect if the player launch type is frameset.

SupplementalQueryStringParametersForAllActivities

Specifies parameter names that, when appended to the launch url, will be forwarded to all content activity pages.

UseDeltaRecordResultsPayload

If this setting is enabled, the payloads for RecordResults requests will be trimmed to only include data that has been updated since the previous successful RecordResults request. This can greatly reduce the size of the RecordResults payload.

RecordResultsMaxPayloadSizeInBytes

ForceFramesetUserAgentRegex

The regex used to determine if a learner's User-Agent should force the course to launch as though the PlayerScoLaunchType were set to FRAMESET, ignoring the configured value. The default value of this setting will not match any User-Agent. This check can be disabled by setting ForceFramesetByRegex to false.

ForceFramesetByRegex

If a learner's User-Agent matches the regex defined by ForceFramesetByRegex, then the SCO will be launched in a frameset, ignoring the PlayerScoLaunchType. These settings can be used to force a package to launch within a frameset on mobile devices while launching the SCO in a new window for desktops.

PlayerPreventWindowResize

Specifies whether the player should allow the learner to resize its windows.

UseLegacyMobileFramesetBehavior

Determines how to handle mobile launches. When set to true, then Engine will use the old behavior (where forceFrameset is needed to do a frameset launch, and SuppressNavbarWhenForcedFrameset is needed to hide the navbar). When set to false, mobile launches will be treated the same way as desktop launches.
