ejbContainer - EJB Container (ejbContainer)

Defines the behavior of the EJB container.

NameTypeDefaultDescription
poolCleanupIntervalA period of time with second precision30sThe 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.
cacheSizeint
Min: 1
2053The number of stateful session bean instances that should be cached in memory.
cacheCleanupIntervalA period of time with second precision3sThe 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.
startEJBsAtAppStartbooleanSpecifies 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
maxUnclaimedRemoteResultsint
Min: 1
1000The 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.
unclaimedRemoteResultTimeoutA period of time with second precision24hThe 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.
contextServiceRefA reference to top level contextService element (string).The context service used to manage context propagation to asynchronous EJB method threads.

asynchronous > contextService

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

timerService

Defines the behavior of the EJB timer service.

NameTypeDefaultDescription
lateTimerThresholdA period of time with minute precision5mNumber 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.
nonPersistentRetryIntervalA period of time with second precision300sWhen 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.
nonPersistentMaxRetriesint
Min: -1
-1When 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.
persistentExecutorRefA reference to top level persistentExecutor element (string).Schedules and runs EJB persistent timer tasks.

timerService > persistentExecutor

Schedules and runs EJB persistent timer tasks.

NameTypeDefaultDescription
enableTaskExecutionbooleantrueDetermines whether or not this instance may run tasks.
initialPollDelayA period of time with millisecond precision0Duration 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.
pollIntervalA period of time with millisecond precision-1Interval 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.
retryIntervalA period of time with millisecond precision1mThe 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.
retryLimitshort
Min: -1

Max: 10000
10Limit 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.
taskStoreRefA reference to top level databaseStore element (string).defaultDatabaseStorePersistent store for scheduled tasks.
contextServiceRefA reference to top level contextService element (string).DefaultContextServiceConfigures how context is captured and propagated to threads.
pollSizeint
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.
