EJB Container (ejbContainer)

Defines the behavior of the EJB container.

NameTypeDefaultDescription

cacheCleanupInterval

A period of time with second precision

3s

The interval between passivating unused stateful session bean instances when the size is exceeded. Specify a positive integer followed by a unit of time, which can be hours (h), minutes (m), or seconds (s). For example, specify 30 seconds as 30s. You can include multiple values in a single entry. For example, 1m30s is equivalent to 90 seconds.

cacheSize

int
Min: 1

2053

The number of stateful session bean instances that should be cached in memory.

poolCleanupInterval

A period of time with second precision

30s

The interval between removing unused bean instances. This setting only applies to stateless session and message-driven beans. Specify a positive integer followed by a unit of time, which can be hours (h), minutes (m), or seconds (s). For example, specify 30 seconds as 30s. You can include multiple values in a single entry. For example, 1m30s is equivalent to 90 seconds.

startEJBsAtAppStart

boolean

Specifies when EJB types will be initialized. If this property is set to true, EJB types will be initialized at the time applications are first started. If this property is set to false, EJB types will be initialized at the time the EJB type is first used by an application. If this property is not set, the behavior is determined on a bean-by-bean basis from the start-at-app-start attribute in the ibm-ejb-jar-ext.xml file. This setting does not apply to either message-driven or startup singleton beans. Message-driven and startup singleton beans will always be initialized at the time applications are started.

asynchronous

Defines the behavior of EJB asynchronous methods.

NameTypeDefaultDescription

contextServiceRef

A reference to top level contextService element (string).

The context service used to manage context propagation to asynchronous EJB method threads.

maxUnclaimedRemoteResults

int
Min: 1

1000

The maximum number of unclaimed results that the server retains from all remote asynchronous method calls that return a Future object. If the maximum is exceeded, the server purges the result of the method call that completed the longest ago to prevent memory leakage.

unclaimedRemoteResultTimeout

A period of time with second precision

24h

The amount of time that the server retains the result for each remote asynchronous method call that returns a Future object. If an application does not claim the result within the specified period of time, the server purges the result of that method call to prevent memory leakage. Specify a positive integer followed by a unit of time, which can be hours (h), minutes (m), or seconds (s). For example, specify 30 seconds as 30s. You can include multiple values in a single entry. For example, 1m30s is equivalent to 90 seconds.

asynchronous > contextService

The context service used to manage context propagation to asynchronous EJB method threads.

NameTypeDefaultDescription

jndiName

string

JNDI name

onError

  • FAIL

  • IGNORE

  • 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.
FAIL
Server will issue a warning or error message on the first error occurrence and then stop the server.
IGNORE
Server will not issue any warning and error messages when it incurs a configuration error.
WARN
Server will issue warning and error messages when it incurs a configuration error.

timerService

Defines the behavior of the EJB timer service.

NameTypeDefaultDescription

lateTimerThreshold

A period of time with minute precision

5m

Number of minutes after the scheduled expiration of a timer that the start of the timer will be considered late. When a timer does start late, a warning message will be logged indicating that the timer has started later than scheduled. The default threshold is 5 minutes and a value of 0 minutes turns off the warning message feature. Specify a positive integer followed by a unit of time, which can be hours (h) or minutes (m). For example, specify 30 minutes as 30m. You can include multiple values in a single entry. For example, 1h30m is equivalent to 90 minutes.

nonPersistentMaxRetries

int
Min: -1

-1

When a non-persistent timer expires, the timeout callback method is called. This setting controls how many times the EJB container attempts to retry the timer. If the transaction for this callback method fails or is rolled back, the EJB container must retry the timer at least once. The default value is -1, which means the EJB container retries infinitely until the timer is successful. If the value is set to 0, the EJB container does not retry the timer, however, this results in behavior that is not compliant with the EJB specification.

nonPersistentRetryInterval

A period of time with second precision

300s

When a non-persistent timer expires, the timeout callback method is called. If the transaction for this callback method fails or is rolled back, the container must retry the timer. The first retry attempt occurs immediately, and subsequent retry attempts are delayed by the number of seconds specified. If the value is set to 0, then all retries occur immediately. If you do not specify a value, the default interval is 300 seconds. Specify a positive integer followed by a unit of time, which can be hours (h), minutes (m), or seconds (s). For example, specify 30 seconds as 30s. You can include multiple values in a single entry. For example, 1m30s is equivalent to 90 seconds.

persistentExecutorRef

A reference to top level persistentExecutor element (string).

Schedules and runs EJB persistent timer tasks.

timerService > persistentExecutor

Schedules and runs EJB persistent timer tasks.

NameTypeDefaultDescription

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.

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
Min: 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
Min: -1

Max: 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.

timerService > persistentExecutor > contextService
