This page contains description of OpenHub behaviour's configuration. If you want to know configuration model then see External configuration model page.

Core configuration

Asynchronous algorithm configuration

Common recommendations for configuration:

set email addresses of administrators (ohf.admin.mail) because OpenHub sends notifications to these addresses, for example when
- message processing failed
- if message waits for response from external system for more then defined interval
set username and password to access different services - parameters security.user.* (security.user.ws-* for web services, security.user.web-* for web, security.user.monitoring-* for monitoring)
path to log folder (log.folder.path)

All the following parameters (apart from log.folder.path and log.folder.pattern) are saved in database with default values. If you want to override any of these parameters then use approach described in external configuration model.

Parameter	Default value	Description
ohf.asynch.countPartlyFailsBeforeFailed	3	Count of unsuccessful tries of message processing before message will be marked as completely FAILED Time interval between tries is defined by asynch.partlyFailedInterval.
ohf.asynch.repairRepeatTimeSec	300	Max. interval in seconds how long can be message being processed, in other words how long can be in PROCESSING state. If message is still in processing then repair process (org.openhubframework.openhub.core.common.asynch.repair.RepairProcessingMsgRoute) will be started and the message state will be changed to PARTLY_FAILED. This parameter is not only for messages themselves but also for external calls and confirmations.
ohf.asynch.concurrentConsumers	30	Input asynchronous messages are waiting for processing in the priority queue. This parameter determines how many concurrent consumers (=threads) can take message from the queue and start processing. In other words this parameter detemines how many concurrent messages can be processed. For more informacetion se http://camel.apache.org/seda.html, parameter concurrentConsumers
ohf.asynch.partlyFailedRepeatTimeSec	60	How often to run process (org.openhubframework.openhub.core.common.asynch.queue.PartlyFailedMessagesPoolRoute) for pooling PARTLY_FAILED messages (in seconds). This parameter is relevant to asynch.partlyFailedInterval.
ohf.asynch.partlyFailedIntervalSec	60	Interval (in seconds) between two tries of PARTLY_FAILED messages. When this interval expires then can be message be processed again. This parameter is relevant to asynch.partlyFailedRepeatTime.
ohf.asynch.confirmation.failedLimitSec	3	Maximum count of confirmation fails when will finish further processing of confirmation, confirmation fails.
ohf.asynch.confirmation.repeatTimeSec	60	How often to run process (org.openhubframework.openhub.core.common.asynch.confirm.ConfirmationsPoolRoute) for pooling failed confirmations (in seconds) This parameter is relevant to asynch.confirmation.interval.
ohf.asynch.confirmation.intervalSec	60	Interval (in seconds) between two tries of failed confirmations. This parameter is relevant to asynch.confirmation.repeatTime.
ohf.asynch.externalCall.skipUriPattern		Regular expression that defines URIs which will be ignored by extcall component. Useful when you want to skip communication with an external system.
ohf.asynch.postponedIntervalSec	5	Interval (in seconds) after that can be postponed message processed again.
ohf.asynch.postponedIntervalWhenFailedSec	300	Interval (in seconds) after that postponed messages will fail. See Guaranteed message processing order functionality for more details.
ohf.asynch.finalMessages.processingEnabled	false	Final messages processing enabled or disabled. See Final messages handling functionality for more details. Note: cannot be defined in database, needs to be in properties (requires application restart if changes).
ohf.asynch.finalMessages.processingIntervalSec	3600	Final messages processing job interval, in seconds.
ohf.asynch.finalMessages.iterationMessageLimit	10000	Maximum number of final messages processed per job.
ohf.asynch.finalMessages.ok.saveTimeInSec	0	Duration in seconds to keep messages in OK state in the datastore. After this period expires and if there is no other action with the message, it will be processed as final (deleted by default). "0" : messages will be processed as soon as possible (depends on the value of ohf.asynch.finalMessages.processingIntervalSec parameter) "-1": messages in this state will be kept indefinitely
ohf.asynch.finalMessages.cancel.saveTimeInSec	2592000 (30d)	Duration in seconds to keep messages in CANCEL state in the datastore.
ohf.asynch.finalMessages.failed.saveTimeInSec	2592000 (30d)	Duration in seconds to keep messages in FAILED state in the datastore.
ohf.asynch.finalMessages.deleteProcessor.enabled	true	Enable/disable processor that does delete messages Note: to enable this processor then also the whole processing job must be enabled - see ohf.asynch.finalMessages.processingEnabled

Web console configuration

Parameter	Default value	Description
ohf.admin.console.messages.limit	100	Maximum count of messages which can be displayed in filtering.
ohf.admin.console.session-concurrency.limit	2	Maximum count of concurrent user sessions at one moment.

Miscellaneous configuration

Parameter	Default value	Description
ohf.cluster.actualNodeInstance.code	LocalNode	Property which identifies node in cluster environment. This property is used for example by logging platform to mark log event with stamp of specific cluster node and for binding with database node record.
ohf.mail.admin.enabled	false	True for enabling sending emails to administrators.
ohf.mail.admin		Administrator email(s) If more emails, then separated them with semicolon if empty then email won't be sent.
ohf.mail.from	OpenHub framework <openhub@openwise.cz>	Email address FROM for sending emails
ohf.mail.smtp.server	localhost	SMTP server for sending emails
ohf.dir.temp		Directory for storing temporary files, related to file upload component.
ohf.dir.fileRepository		File repository directory where files will be stored, related to file upload component.
ohf.server.localhostUri.check	false	Enable/disable checking of ohf.server.localhostUri
ohf.server.localhostUri	http://localhost:8080	URI of this localhost application, including port number. Related to cluster nodes evidence. If ohf.server.localhostUri.check=true then this URI is checked during OpenHub initialization.
ohf.disable.throttling	false	True for disabling throttling at all. See throttling component.
ohf.endpoints.includePattern	^(spring-ws\|servlet).*$	Pattern for filtering endpoints URI - only whose URIs will match specified pattern will be returned, related to endpoints overview.
ohf.requestSaving.enable	false	True for enabling saving requests/responses for filtered endpoints URI.
ohf.requestSaving.endpointFilter	^(spring-ws\|servlet).*$	Pattern for filtering endpoints URI which requests/response should be saved.
ohf.alerts.repeatTimeSec	300	How often to run checking of alerts (in seconds)
log.folder.path	${log.folder}, value is from Maven profile	Path to folder with application logs, used in logs searching in admin GUI.
log.file.pattern	(^.\\.log$\|^.\\.log\\.2\\d{3}-(0[1-9]\|1[0-9])-[0\|1\|2\|3]\\d?_\\d*\\.gz$)	Defines format of log file names (include filter) which will be taking into logs searching in admin GUI.
ohf.uri.inputPattern	^(spring-ws\|servlet).*$	Pattern for filtering input routes (used in Stopping mode)

Throttling

Throttling functionality is implemented by throttling component where you find description of the configuration.

Alerts

See alerts for description.

Restrict Spring bean inicialization

If there are many Spring beans with route definitions then startup time for loading ESB application can be quite long. This functionality enables to include only those Spring beans which should be initialized or exclude those Spring beans which we don't want to initialize.

It can be handy during development because it's possible via system properties to restrict set of Spring beans (=Camel routes) which will be initialized.

There are two handy classes for these purposes: org.openhubframework.openhub.common.spring.SystemIncludeRegexPatternTypeFilter and org.openhubframework.openhub.common.spring.SystemExcludeRegexPatternTypeFilter

Both type filters are handled by system or environment property. springIncludePattern for SystemIncludeRegexPatternTypeFilter class, springExcludePattern for SystemExcludeRegexPatternTypeFilter class. System property has higher priority.

Example of system property definition for exclude filter (excludes all Spring beans under org.openhubframework.openhub.modules package and sub-packages):

-DspringExcludePattern=org\.openhubframework\.openhub\.modules\..*

Include filters are applied after exclude filters.

Configuration checking

Configuration checker (org.openhubframework.openhub.core.conf.ConfigurationChecker) enables to check selected configuration parameters during application start:

ohf.server.localhostUri - checks URI availability (must be explicitly enabled by parameter ohf.server.localhostUri.check, default value is false)
ohf.endpoints.includePattern, ohf.requestSaving.endpointFilter - checks regular expressions

You can implement your own checking functionality by org.openhubframework.openhub.core.conf.ConfCheck.
