Method Summary

Modifier and Type	Method and Description
String	forceTransactionCompletion(Xid xid, boolean commit) Replays the given transaction by re-running the prepare and commit.
String	forceTransactionCompletionFromCluster(Xid xid, Address where, boolean commit) This method invokes RecoveryManager.forceTransactionCompletion(javax.transaction.xa.Xid, boolean) on the specified node.
Set<RecoveryManager.InDoubtTxInfo>	getInDoubtTransactionInfo() Same as RecoveryManager.getInDoubtTransactionInfoFromCluster(), but only returns transactions from the local node.
Set<RecoveryManager.InDoubtTxInfo>	getInDoubtTransactionInfoFromCluster() Returns a Set containing all the in-doubt transactions from the cluster, including the local node.
List<Xid>	getInDoubtTransactions() Local call that returns a list containing:
ConcurrentMap<RecoveryInfoKey,RecoveryAwareRemoteTransaction>	getInDoubtTransactionsMap()
RecoveryAwareRemoteTransaction	getPreparedTransaction(Xid xid) Local call returning the remote transaction identified by the supplied xid or null.
RecoveryManager.RecoveryIterator	getPreparedTransactionsFromCluster() Returns the list of transactions in prepared state from both local and remote cluster nodes.
void	init(RpcManager rpcManager, CommandsFactory commandsFactory, TransactionTable txTable, TransactionCoordinator txCoordinator, TransactionFactory txFactory)
boolean	isTransactionPrepared(GlobalTransaction globalTx) Checks both internal state and transaction table's state for the given tx.
void	registerInDoubtTransaction(RecoveryAwareRemoteTransaction remoteTransaction)
void	removeRecoveryInformation(Collection<Address> lockOwners, Xid xid, boolean sync, GlobalTransaction gtx, boolean fromCluster) Removes from the specified nodes (or all nodes if the value of 'where' is null) the recovery information associated with these Xids.
RecoveryAwareTransaction	removeRecoveryInformation(Long internalId) Same as RecoveryManager.removeRecoveryInformation(javax.transaction.xa.Xid) but identifies the tx by its internal id.
RecoveryAwareTransaction	removeRecoveryInformation(Xid xid) Remove recovery information stored on this node (doesn't involve rpc).
void	removeRecoveryInformationFromCluster(Collection<Address> where, long internalId, boolean sync) Same as RecoveryManager.removeRecoveryInformation(java.util.Collection, javax.transaction.xa.Xid, boolean, org.infinispan.transaction.xa.GlobalTransaction, boolean) but the transaction is identified by its internal id, and not by its xid.

Method Detail

init

public void init(RpcManager rpcManager,
                 CommandsFactory commandsFactory,
                 TransactionTable txTable,
                 TransactionCoordinator txCoordinator,

getPreparedTransactionsFromCluster

public RecoveryManager.RecoveryIterator getPreparedTransactionsFromCluster()

Description copied from interface: RecoveryManager

Returns the list of transactions in prepared state from both local and remote cluster nodes. Implementation can take advantage of several optimisations:

• in order to get all tx from the cluster a broadcast is performed. This can be performed only once (assuming the call is successful), the first time this method is called. After that a local, cached list of tx prepared on this node is returned.
• during the broadcast just return the list of prepared transactions that are not originated on other active nodes of the cluster.

Specified by:

getPreparedTransactionsFromCluster in interface RecoveryManager

removeRecoveryInformation

public void removeRecoveryInformation(Collection<Address> lockOwners,
                                      Xid xid,
                                      boolean sync,
                                      GlobalTransaction gtx,
                                      boolean fromCluster)

Description copied from interface: RecoveryManager

Removes from the specified nodes (or all nodes if the value of 'where' is null) the recovery information associated with these Xids.

Specified by:

removeRecoveryInformation in interface RecoveryManager

Parameters:

lockOwners - on which nodes should this be executed.

xid - the list of xids to be removed.

sync - execute sync or async (false)

gtx - the global transaction

removeRecoveryInformationFromCluster

public void removeRecoveryInformationFromCluster(Collection<Address> where,
                                                 long internalId,
                                                 boolean sync)

Description copied from interface: RecoveryManager

Same as RecoveryManager.removeRecoveryInformation(java.util.Collection, javax.transaction.xa.Xid, boolean, org.infinispan.transaction.xa.GlobalTransaction, boolean) but the transaction is identified by its internal id, and not by its xid.

Specified by:

removeRecoveryInformationFromCluster in interface RecoveryManager

removeRecoveryInformation

public RecoveryAwareTransaction removeRecoveryInformation(Xid xid)

Description copied from interface: RecoveryManager

Remove recovery information stored on this node (doesn't involve rpc).

Specified by:

removeRecoveryInformation in interface RecoveryManager

removeRecoveryInformation

public RecoveryAwareTransaction removeRecoveryInformation(Long internalId)

Description copied from interface: RecoveryManager

Same as RecoveryManager.removeRecoveryInformation(javax.transaction.xa.Xid) but identifies the tx by its internal id.

Specified by:

removeRecoveryInformation in interface RecoveryManager

getInDoubtTransactions

public List<Xid> getInDoubtTransactions()

Description copied from interface: RecoveryManager

Local call that returns a list containing:

 - all the remote transactions prepared on this node for which the originator(i.e. the node where the tx
 stared) is no longer part of the cluster.
 AND
 - all the locally originated transactions which are prepared and for which the commit failed
