Interface TransactionManager

All Superinterfaces:

ClientTransactionManager, TransactionManager

All Known Subinterfaces:

ServerTransactionManager

public interface TransactionManager

extends ClientTransactionManager

Allows XA resources to register and unregister themselves with the Transaction Manager on startup. It also allows a transaction to be suspended and resumed.

RESOURCE_TYPE

static final String RESOURCE_TYPE

A constant that is used as the type of the resource registration property that determines the resource type of the resource being registered.

See Also:

TransactionManager.registerResource(String, XAResource, Hashtable), TransactionManager.RESOURCE_DATASOURCE, TransactionManager.RESOURCE_JMS, TransactionManager.RESOURCE_JCA, TransactionManager.RESOURCE_OTHER, Constant Field Values

RESOURCE_DATASOURCE

static final String RESOURCE_DATASOURCE

This indicates the resource being registered is datasource.

See Also:

TransactionManager.registerResource(String, XAResource, Hashtable), TransactionManager.RESOURCE_TYPE, Constant Field Values

RESOURCE_JMS

static final String RESOURCE_JMS

This indicates the resource being registered is jms.

See Also:

TransactionManager.registerResource(String, XAResource, Hashtable), TransactionManager.RESOURCE_TYPE, Constant Field Values

RESOURCE_JCA

static final String RESOURCE_JCA

This indicates the resource being registered is jca.

See Also:

TransactionManager.registerResource(String, XAResource, Hashtable), TransactionManager.RESOURCE_TYPE, Constant Field Values

RESOURCE_OTHER

static final String RESOURCE_OTHER

This indicates the resource being registered is xa resource other than datasource, jms and jca.

See Also:

TransactionManager.registerResource(String, XAResource, Hashtable), TransactionManager.RESOURCE_TYPE, Constant Field Values

ENLISTMENT_TYPE

static final String ENLISTMENT_TYPE

A constant that is used as the name of the resource registration property that determines the enlistment style of the resource being registered.

See Also:

TransactionManager.registerResource(String, XAResource, Hashtable), TransactionManager.ENLISTMENT_DYNAMIC, TransactionManager.ENLISTMENT_STATIC, TransactionManager.ENLISTMENT_STANDARD, Constant Field Values

ENLISTMENT_DYNAMIC

static final String ENLISTMENT_DYNAMIC

This enlistment mode requires the resource to dynamically enlist with the transaction manager when accessed by the application.

See Also:

TransactionManager.registerResource(String, XAResource, Hashtable), TransactionManager.ENLISTMENT_TYPE, Constant Field Values

ENLISTMENT_STATIC

static final String ENLISTMENT_STATIC

Registering the XA resource statically means that the transaction service always enlists the resource when a transaction is attached to a thread. In other words, the resource is not expected to enlist itself when used. It is important to emphasize the fact that once a resource is registered statically, it gets automatically enlisted in every transaction.

See Also:

TransactionManager.registerResource(String, XAResource, Hashtable), TransactionManager.ENLISTMENT_TYPE, Constant Field Values

ENLISTMENT_STANDARD

static final String ENLISTMENT_STANDARD

Allows an application or XAResource adaptor to register a XA resource dynamically, typically before the resource is made available to the application. The resource should enlist itself once with the transaction that it participates in. The Transaction Manager will perform subsequent re-enlistment of the resource in the transaction if necessary. Delistment is optional.

See Also:

TransactionManager.registerResource(String, XAResource, Hashtable), TransactionManager.ENLISTMENT_TYPE, Constant Field Values

INTERLEAVING_ENLISTMENTS

static final String INTERLEAVING_ENLISTMENTS

A constant that is used as the name of the registration property that controls interleaving enlistments. When set to false, only a single thread will be allowed to be enlisted with a particular XAResource instance at any given time. Other threads attempting to enlist with an XAResource instance that is already enlisted will be blocked until the other application thread delists the resource from its transaction. The default value is true.

See Also:

TransactionManager.registerResource(String, XAResource, Hashtable), Constant Field Values

CALL_SET_TRANSACTION_TIMEOUT

static final String CALL_SET_TRANSACTION_TIMEOUT

A constant that is used as the name of the registration property that controls whether the transaction manager sets the resource timeout. When set to true, the transaction manager will call XAResource.setTransactionTimeout for each resource enlistment with a value approximately equal to that of the global transaction timeout. The default value is false.

See Also:

TransactionManager.registerResource(String, XAResource, Hashtable), Constant Field Values

LOCAL_ASSIGNMENT_OF_REMOTE_RESOURCES

static final String LOCAL_ASSIGNMENT_OF_REMOTE_RESOURCES

A constant that is used as the name of the registration property that controls how participating resources are assigned to servers. When set to true, a resource enlisted in the transaction on a non-coordinating server will be assigned to the coordinating server to perform XAResource operation if that resource is registered on the coordinating server. Setting this option to false will cause the transaction manager to always assign resources to a server where the resource was enlisted. The default value is true.

See Also:

TransactionManager.registerResource(String, XAResource, Hashtable), Constant Field Values

ASYNC_TIMEOUT_DELIST

static final String ASYNC_TIMEOUT_DELIST

A constant that is used as the name of the registration property that controls whether an enlisted resource is delisted by a different thread that is processing the transaction timeout prior to the timeout thread's invocation of XAResource.rollback.

See Also:

TransactionManager.registerResource(String, XAResource, Hashtable), Constant Field Values

THREAD_AFFINITY

static final String THREAD_AFFINITY

A constant that is used as the name of the registration property that controls whether an enlisted resource needs thread affinity. i.e, XA.start and XA.end should happen on the same thread.

See Also:

TransactionManager.registerResource(String, XAResource, Hashtable), Constant Field Values

RECOVER_RETRY_DURATION_SECONDS

static final String RECOVER_RETRY_DURATION_SECONDS

A constant that is used as the name of the registration property that controls whether recover will be retried for the specified duration in seconds. The default value is 0.

See Also:

Constant Field Values

RECOVER_RETRY_INTERVAL_SECONDS

static final String RECOVER_RETRY_INTERVAL_SECONDS

A constant that is used as the name of the registration property that controls the frequency in seconds at which the recover operation is performed on the resource. The default value is 30. Setting this registration option has no effect unless there is a positive value assigned for the RECOVER_RETRY_DURATION_SECONDS registration option.

See Also:

TransactionManager.RECOVER_RETRY_DURATION_SECONDS, Constant Field Values

CALL_SET_DELIST_TMSUCCESS_ALWAYS

static final String CALL_SET_DELIST_TMSUCCESS_ALWAYS

A constant that is used as the name of the registration property that controls whether the transaction manager sets the delistment flag . When set to true, the transaction manager will call delistment with the XAResource.TMSUCCESS flag before prepare.

See Also:

TransactionManager.registerResource(String, XAResource, Hashtable), Constant Field Values

CALL_SET_DELIST_TMSUCCESS_INSTEAD_OF_TMSUSPEND

static final String CALL_SET_DELIST_TMSUCCESS_INSTEAD_OF_TMSUSPEND

A constant that is used as the name of the registration property that controls whether the transaction manager sets the delistment flag . When set to true, the transaction manager will call delistment with the XAResource.TMSUCCESS instead of calling delistment with the XAResource.TMSUPEND.

See Also:

TransactionManager.registerResource(String, XAResource, Hashtable), Constant Field Values

FIRST_RESOURCE_COMMIT

static final String FIRST_RESOURCE_COMMIT

registerStaticResource

void registerStaticResource(String name,
                            XAResource xar)
                            throws SystemException

Allows an application or XAResource adaptor to register a XA resource statically, typically before the resource is made available to the application. Registering the XA resource statically means that the transaction service always enlists the resource when a transaction is attached to a thread. In other words, the resource is not expected to enlist itself when used. It is important to emphasize the fact that once a resource is registered statically, it gets automatically enlisted in every transaction.

While optional, this call improves performance during an enlistResource operation. If an enlistResource call is made and the resource (or another instance of its type) has not previously been registered, the transaction service automatically registers the new resource dynamically using the class name of the resource as the name. See below for description of registering a XA resource dynamically.

In a multi-tenant environment this register method must be invoked with the proper CIC (component invocation context) on the calling thread. This CIC will be used for subsequent transaction resource callbacks. The registerStaticResource method has the following parameters:

Parameters:

name - The name of the resource. This name is used in error messages as well as in the branch qualifier part of all transaction ids supplied to the resource.

xar - A reference to a XAResource object that is subsequently used to handle recovery. It can also be the weblogic extension weblogic.transaction.XAResource.

Throws:

SystemException
