Method Details
-
begin
Create a new transaction and associate it with the current thread.- Throws:
NotSupportedException
- Thrown if the thread is already associated with a transaction and the Transaction Manager implementation does not support nested transactions.SystemException
- Thrown if the transaction manager encounters an unexpected error condition.
-
commit
void commit() throws RollbackException, HeuristicMixedException, HeuristicRollbackException, SecurityException, IllegalStateException, SystemExceptionComplete the transaction associated with the current thread. When this method completes, the thread is no longer associated with a transaction.- Throws:
RollbackException
- Thrown to indicate that the transaction has been rolled back rather than committed.HeuristicMixedException
- Thrown to indicate that a heuristic decision was made and that some relevant updates have been committed while others have been rolled back.HeuristicRollbackException
- Thrown to indicate that a heuristic decision was made and that all relevant updates have been rolled back.SecurityException
- Thrown to indicate that the thread is not allowed to commit the transaction.IllegalStateException
- Thrown if the current thread is not associated with a transaction.SystemException
- Thrown if the transaction manager encounters an unexpected error condition.
-
getStatus
Obtain the status of the transaction associated with the current thread.- Returns:
- The transaction status. If no transaction is associated with the current thread, this method returns the Status.NoTransaction value.
- Throws:
SystemException
- Thrown if the transaction manager encounters an unexpected error condition.
-
getTransaction
Get the transaction object that represents the transaction context of the calling thread.- Returns:
- the
Transaction
object representing the transaction associated with the calling thread. - Throws:
SystemException
- Thrown if the transaction manager encounters an unexpected error condition.
-
resume
void resume(Transaction tobj) throws InvalidTransactionException, IllegalStateException, SystemException Resume the transaction context association of the calling thread with the transaction represented by the supplied Transaction object. When this method returns, the calling thread is associated with the transaction context specified.- Parameters:
tobj
- TheTransaction
object that represents the transaction to be resumed.- Throws:
InvalidTransactionException
- Thrown if the parameter transaction object contains an invalid transaction.IllegalStateException
- Thrown if the thread is already associated with another transaction.SystemException
- Thrown if the transaction manager encounters an unexpected error condition.
-
rollback
Roll back the transaction associated with the current thread. When this method completes, the thread is no longer associated with a transaction.- Throws:
SecurityException
- Thrown to indicate that the thread is not allowed to roll back the transaction.IllegalStateException
- Thrown if the current thread is not associated with a transaction.SystemException
- Thrown if the transaction manager encounters an unexpected error condition.
-
setRollbackOnly
Modify the transaction associated with the current thread such that the only possible outcome of the transaction is to roll back the transaction.- Throws:
IllegalStateException
- Thrown if the current thread is not associated with a transaction.SystemException
- Thrown if the transaction manager encounters an unexpected error condition.
-
setTransactionTimeout
Modify the timeout value that is associated with transactions started by the current thread with the begin method.If an application has not called this method, the transaction service uses some default value for the transaction timeout.
- Parameters:
seconds
- The value of the timeout in seconds. If the value is zero, the transaction service restores the default value. If the value is negative a SystemException is thrown.- Throws:
SystemException
- Thrown if the transaction manager encounters an unexpected error condition.
-
suspend
Suspend the transaction currently associated with the calling thread and return a Transaction object that represents the transaction context being suspended. If the calling thread is not associated with a transaction, the method returns a null object reference. When this method returns, the calling thread is not associated with a transaction.- Returns:
- Transaction object representing the suspended transaction.
- Throws:
SystemException
- Thrown if the transaction manager encounters an unexpected error condition.
