Server Side Properties

The server side properties, residing in a file carnot.properties in the classpath have to be available in the Stardust runtime environment. You will find this file in the root directory of the carnot-engine.jar that is included within the carnot.ear file.

In case of Spring local mode, both Stardust property files (client and server) have to be merged.

Engine

Parameters Property Description Default Range
Carnot.Engine.Classloading.UseContextClassloader Boolean enables the usage of ContextClassLoader when loading classes by reflection. false true, false
Carnot.Engine.OverridableTimeStamps Boolean option if time stamps are overridable false
Carnot.Engine.ErrorHandling.ApplicationExceptionPropagation affects how the engine handles exceptions raised by invoked applications/services. Please refer to the chapter Exceptions for a detailed description on the usage of this property. never
  • never - The exception is consumed by the engine and not propagated to the client. The engine sets both, the activity instance and the process instance, to interrupted state and logs the exception to the audit trail. After that, the engine attempts to commit the transaction and stops the execution of the process. The activity (and process) execution may be resumed after running the process instance recovery.
    Please note that the engine does not check the status of the transaction, and therefore if the transaction is already set to rollback then all the actions performed in this transaction will be lost.
  • onRollback - The behavior depends on the status of the current transaction. If the transaction is set to RollbackOnly, similarly with "always", the engine attempts to log the original exception to the audit trail in a separate transaction and after that, the exception is propagated to the client (re-thrown).
    If the transaction is not set to RollbackOnly, then it will behave like "never" and it will attempt to interrupt the activity instance and the process instance.
  • always - The engine is automatically rolling back the transaction. The engine attempts to log the original exception to the audit trail in a separate transaction. After that, the exception is propagated to the client (re-thrown).

Carnot.Engine.Tuning.Query.DescriptorPrefetchDataDiscriminationThreshold Double Fetches all data values from the audit trail if the ratio between the actual used number of data to the total data objects defined in the model is less or equal to this value. Otherwise just those non-clustered data values are fetched which are required for the descriptors in question. 1.0
Carnot.Engine.Tuning.Query.DescriptorPrefetchBatchSize Integer This is the default for all other *PrefetchNParallel settings and is not used dedicated for any query type. 400
Carnot.Engine.Tuning.Query.InlineProcessOidThreshold Long Some queries needs to perform a preprocessing step to determine the list of process instances for which the query result is filtered. If the number of determined process instances is smaller than the configured value, then the list of OIDs will be inlined in the where clause of the query, otherwise the filtering will be performed in a post processing step. 100
Carnot.Engine.Tuning.Query.DescriptorPrefetchStructIndex Long Configuration switch to determine if indexed XPaths should be prefetched for descriptors. false
Carnot.Engine.Tuning.Query.DescriptorPrefetchStructXml Long Configuration switch to determine if structured data XML should be prefetched for descriptors from table clob_data. Operations on clob_data are performed using prepared statement only. true

Infinity.Engine.Tuning.Query.ActivateNextActivityInstance.Retries Integer Determines the number of retries until receiving an activity instance defined by the query. 5
Carnot.Engine.Tuning.GetCountDefaultTimeout Long Determines the timeout value in seconds for getCount() method call to avoid a query timeout resulting in a rollback of the complete transaction. This property is used for internal JDBC queries.
Try to use a property value as low as possible and as high as necessary:
The higher the value the longer an implicit JDBC count will wait for the correct result. On the other hand this might result in slow responses in case that the count cannot be executed in a reasonable time.
Note that this value should not to be mistaken with the timeout value which can be set for queries in general by the TimeoutPolicy!		 5 s
Carnot.Engine.Tuning.SequenceBatchSize Integer Determines the number of sequences loaded as a batch. 100

Carnot.Engine.Tuning.SupportTransientProcesses String The following values determine whether transient processing is available at all and how the corresponding model properties are handled:
  • on - is the prerequisite for executing process instances transiently. The process definition modeling property determines how it is executed.
  • alwaysTransient - all process instances will be executed transiently, if they are applicable for transient process execution. This does not depend on the corresponding modeling property of the underlying process definition.
  • alwaysDeferred - all process instances will be executed with deferred persistence. The process instance will not be persisted until it has been completed, if applicable to the process definition topology. This does not depend on the corresponding modeling property of the underlying process definition.
  • off - disables the Transient Process Instance functionality globally and the process definition modeling property as well as the process instance runtime property have no effect.
 off
Carnot.Engine.Tuning.SupportTransientProcesses.ClusterSafeObjectProvider String The provider class to be used for cluster safe objects in order to cope with transient process instances. org.eclipse.stardust.engine.core.persistence.jdbc.transientpi.ClusteredEnvHazelcastObjectProvider

  • true: ensures that during the execution of transient process instances the process instance in question and all related persistents are accessible via API (e.g. via WorkflowService#getProcessInstance(long))
  • false: in-memory storage is not exposed. Thus a significant performance improvement can be achieved due to internal optimizations, which can be done only if there's no need for exposing the in-memory storage.
