Interface InterposedTransactionManager

public interface InterposedTransactionManager

InterposedTransactionManager is used by a bi-directional gateway for importing foreign transactions into WLS. Gateway implementors obtain a XAResource interface from the WLS Transaction Manager to import foreign transactions into WLS, and to coordinate the foreign transactions.

InterposedTransactionManager is available via JNDI lookup under the path of "weblogic.transaction.coordinators." and from weblogic.transaction.TxHelper.

Note that we do not yet support importing the same foreign transaction into different WLS domains via our Client InterposedTransactionManager.

Method Summary

Modifier and Type	Method and Description
Transaction	getTransaction() Gets the transaction object that is associated with the current thread
Transaction	getTransaction(Xid xid) Given an Xid returns the corresponding transaction object, if any
XAResource	getXAResource() Obtains the XAResource object associated with this Transaction Manager instance
void	setClusterwideRecoveryEnabled(boolean isClusterwideRecoveryEnabled) Specifies whether recovery operations for a distributed transaction are applied to all the servers of the cluster hosting InterposedTransactionManager rather than just the server hosting the InterposedTransactionManager.

Method Detail

getXAResource

XAResource getXAResource()

Obtains the XAResource object associated with this Transaction Manager instance

Returns:

the XAResource interface implemented by the WLS Transaction Manager. It is used by the gateway for subsequent import and coordination of the foreign transactions.

getTransaction

Transaction getTransaction()

Gets the transaction object that is associated with the current thread

return The transaction object that is associated with the current thread

Returns:

Transaction

getTransaction

Transaction getTransaction(Xid xid)

Given an Xid returns the corresponding transaction object, if any

Parameters:

xid - Specifies the Xid, whether it is a foreign Xid or a WLS Xid

Returns:

The transaction object that is associated with the given Xid

setClusterwideRecoveryEnabled

void setClusterwideRecoveryEnabled(boolean isClusterwideRecoveryEnabled)

Specifies whether recovery operations for a distributed transaction are applied to all the servers of the cluster hosting InterposedTransactionManager rather than just the server hosting the InterposedTransactionManager. When set, this value overrides the value of the ClusterwideRecoveryEnabled attributed set on the server.

Parameters:

isClusterwideRecoveryEnabled - If true, recovery operations are applied to all servers in the cluster hosting the InterposedTransactionManager
