startRecovery

XAResourceHolderState startRecovery()
                             throws RecoveryException

Prepare the recoverable XAResource producer for recovery.

Returns:

a XAResourceHolderState object that can be used to call recover().

RecoveryException - thrown when a XAResourceHolderState cannot be acquired.

endRecovery

void endRecovery()
          throws RecoveryException

Release internal resources held after call to startRecovery().

Throws:

RecoveryException - thrown when an error occured while releasing reserved resources.

setFailed

void setFailed(boolean failed)

Mark this resource producer as failed or not. A resource is considered failed if recovery fails to run on it.

Parameters:

failed - true is the resource must be considered failed, false it it must be considered sane.

findXAResourceHolder

XAResourceHolder findXAResourceHolder(javax.transaction.xa.XAResource xaResource)

Find in the XAResourceHolders created by this XAResourceProducer the one which this XAResource belongs to.

Parameters:

xaResource - the XAResource to look for.

Returns:

the associated XAResourceHolder or null if the XAResource does not belong to this XAResourceProducer.

init

void init()

Initialize this XAResourceProducer's internal resources.

close

void close()

Release this XAResourceProducer's internal resources.

createPooledConnection

XAStatefulHolder createPooledConnection(java.lang.Object xaFactory,
                                        ResourceBean bean)
                                 throws java.lang.Exception

Create a XAStatefulHolder that will be placed in an XAPool.

Parameters:

xaFactory - the vendor's resource-specific XA factory.
