Attributes

Table 37-1 JTA attributes

Attribute	Description	Range of Values and Default
AbandonTimeoutSeconds	Returns the transaction abandon timeout in seconds.	Admin Console field label: Abandon Timeout Seconds Required: no Default: 86400 Minimum: 1 Maximum: 231-1
BeforeCompletionIterationLimit	The maximum number of cycles the transaction manager will perform the beforeCompletion synchronization callback. Nothing prevents a Synchronization object from registering another during beforeCompletion, even those whose beforeCompletions have already been called. For example, an EJB can call another in its ejbStore() method. To accomodate this, the transaction manager calls all Synchronization objects, then repeates the cycle if new ones have been registered. This count sets a limit to the number of cycles that can happen.	Admin Console field label: Before Completion Iteration Limit Required: no Default: 10 Minimum: 1 Maximum: 231-1
CheckpointIntervalSeconds	Interval at which the transaction manager creates a new transaction log file and checks all old transaction log files to see if they are ready to be deleted. Default is 300 seconds (5 minutes); minimum is 10 seconds; maximum is 1800 seconds (30 minutes).	Admin Console field label: Checkpoint Interval Seconds Required: no Default: 300 Minimum: 10 Maximum: 1800
ForgetHeuristics	Returns a boolean indicating whether the transaction manager will automatically perform an XAResource forget operation for transaction heuristic completions.	Admin Console field label: Forget Heuristics Required: no Default: true
MaxResourceRequestsOnServer	Maximum number of concurrent requests to resources allowed for each server.	Required: no Default: 50 Minimum: 10 Maximum: 231-1
MaxResourceUnavailableMillis	Maximum duration in milliseconds that a resource is declared dead. After the duration, the resource will be declared available again, even if the resource provider does not explicitly re-register the resource.	Required: no Default: 1800000 Minimum: 0 Maximum: 263-1
MaxTransactions	The maximum number of simultaneous in-progress transactions allowed on a server.	Admin Console field label: Max Transactions Required: no Default: 10000 Minimum: 1 Maximum: 231-1
MaxUniqueNameStatistics	The maximum number of unique transaction names for which statistics will be maintained. A transaction name typically represents a category of business transactions (such as "funds-transfer")	Admin Console field label: Max Unique Name Statistics Required: no Default: 1000 Minimum: 0 Maximum: 231-1
MaxXACallMillis	Maximum allowed duration of XA calls to resources. If a particular XA call to a resource exceeds the limit, the resource is declared unavailable.	Required: no Default: 120000 Minimum: 0 Maximum: 263-1
Name	The name of this configuration. WebLogic Server uses an MBean to implement and persist the configuration.	Required: no
Notes	Optional information that you can include to describe this configuration.	Required: no
TimeoutSeconds	Returns the transaction timeout in seconds.	Admin Console field label: Timeout Seconds Required: no Default: 30 Minimum: 1 Maximum: 231-1
