Persistent Scheduled Executor (persistentExecutor)

Schedules and runs persistent tasks.

Attribute name Data type Default value Description
contextServiceRef A reference to top level contextService element (string). DefaultContextService Configures how context is captured and propagated to threads.
enableTaskExecution boolean true Determines whether or not this instance may run tasks.
id string   A unique configuration ID.
initialPollDelay A period of time with millisecond precision 0 Duration of time to wait before this instance might poll the persistent store for tasks to run. A value of -1 delays polling until it is started programmatically. Specify a positive integer followed by a unit of time, which can be hours (h), minutes (m), seconds (s), or milliseconds (ms). For example, specify 500 milliseconds as 500ms. You can include multiple values in a single entry. For example, 1s500ms is equivalent to 1.5 seconds.
pollInterval A period of time with millisecond precision -1 Interval between polling for tasks to run. A value of -1 disables all polling after the initial poll. Specify a positive integer followed by a unit of time, which can be hours (h), minutes (m), seconds (s), or milliseconds (ms). For example, specify 500 milliseconds as 500ms. You can include multiple values in a single entry. For example, 1s500ms is equivalent to 1.5 seconds.
pollSize int

Minimum: 1

  The maximum number of task entries to find when polling the persistent store for tasks to run. If unspecified, there is no limit.
retryInterval A period of time with millisecond precision 1m The amount of time that must pass between the second and subsequent consecutive retries of a failed task. The first retry occurs immediately, regardless of the value of this attribute. Specify a positive integer followed by a unit of time, which can be hours (h), minutes (m), seconds (s), or milliseconds (ms). For example, specify 500 milliseconds as 500ms. You can include multiple values in a single entry. For example, 1s500ms is equivalent to 1.5 seconds.
retryLimit short

Minimum: -1

Maximum: 10000

10 Limit of consecutive retries for a task that has failed or rolled back, after which the task is considered permanently failed and does not attempt further retries. A value of -1 allows for unlimited retries.
taskStoreRef A reference to top level databaseStore element (string). defaultDatabaseStore Persistent store for scheduled tasks.
contextService
Description: Configures how context is captured and propagated to threads.
Required: false
Data type:
Attribute name Data type Default value Description
baseContextRef A reference to top level contextService element (string).   Specifies a base context service from which to inherit context that is not already defined on this context service.
jndiName string   JNDI name
onError
  • IGNORE
  • FAIL
  • WARN
WARN Determines the action to take in response to configuration errors. For example, if securityContext is configured for this contextService, but the security feature is not enabled, then onError determines whether to fail, raise a warning, or ignore the parts of the configuration which are incorrect.
IGNORE
Server will not issue any warning and error messages when it incurs a configuration error.
FAIL
Server will issue a warning or error message on the first error occurrence and then stop the server.
WARN
Server will issue warning and error messages when it incurs a configuration error.
contextService > baseContext
Description: Specifies a base context service from which to inherit context that is not already defined on this context service.
Required: false
Data type:
