BitronixTransactionManager

public BitronixTransactionManager()

getReference

public javax.naming.Reference getReference()
                                    throws javax.naming.NamingException

BitronixTransactionManager can only have a single instance per JVM so this method always returns a reference with no special information to find back the sole instance. BitronixTransactionManagerObjectFactory will be used by the JNDI server to get the BitronixTransactionManager instance of the JVM.

Specified by:

getReference in interface javax.naming.Referenceable

Returns:

an empty reference to get the BitronixTransactionManager.

Throws:

javax.naming.NamingException

getInFlightTransactions

public java.util.Map getInFlightTransactions()

Return all in-flight transactions.

Returns:

a map of BitronixTransaction objects using Uid as key and BitronixTransaction as value.

getOldestInFlightTransactionTimestamp

public long getOldestInFlightTransactionTimestamp()

Return the timestamp of the oldest in-flight transaction.

Returns:

the timestamp or Long.MIN_VALUE if there is no in-flight transaction.

getCurrentTransaction

public BitronixTransaction getCurrentTransaction()

Get the transaction currently registered on the current thread context.

Returns:

the current transaction or null if no transaction has been started on the current thread.

dumpTransactionContexts

public void dumpTransactionContexts()

Dump an overview of all running transactions as debug logs.

shutdown

public void shutdown()

Shut down the transaction manager and release all resources held by it.

This call will also close the resources pools registered by the ResourceLoader like JMS and JDBC pools. The manually created ones are left untouched.

The Transaction Manager will wait during a configurable graceful period before forcibly killing active transactions.

After this method is called, attempts to create new transactions (via calls to TransactionManager.begin()) will be rejected with a SystemException.

Specified by:

shutdown in interface Service

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
