Method Detail

recoverXAResources

public static void recoverXAResources(Enumeration xaResources)

Recovers the in doubt transactions from the provided list of XAResource objects. This method is never called by the recovery thread, and its the application threads which wants to pass in the XA resources that call this.

Parameters:

xaResources - enumerated list of XA Resources to be recovered

getRestart

public static byte[] getRestart()

Gets the restart data for the process.

Returns:

The restart data.

setRestart

public static void setRestart(byte[] bytes)

Sets the restart data for the process.

Parameters:

bytes - The restart data.

waitForRecovery

public static void waitForRecovery()

Waits for recovery to complete.

waitForResync

public static void waitForResync()

Waits for resync to complete.

waitForResync

public static void waitForResync(int cmtTimeOut)

Waits for resync to complete with timeout.

Parameters:

cmtTimeout - Container managed transaction timeout

isIncompleteTxRecoveryRequired

public static Boolean isIncompleteTxRecoveryRequired()

sizeOfInCompleteTx

public static int sizeOfInCompleteTx()

recoverIncompleteTx

public static void recoverIncompleteTx(XAResource[] xaresArray)

registerTransactionRecoveryFence

public static void registerTransactionRecoveryFence(TransactionRecoveryFence fence)

Register the implementation of Transaction recovery fence. This service is started as soon as all the resources are available.

startTransactionRecoveryFence

public static void startTransactionRecoveryFence()

Start Transaction recovery fence.

startResyncThread

public static void startResyncThread()
