If the transaction has not been marked rollback only, and all of the participants in the
transaction agree to commit, the transaction is committed and the operation terminates
normally. |

Constructor
public void commit(boolean report_heuristics)
If the transaction has not been marked rollback only, and all of the participants in the
transaction agree to commit, the transaction is committed and the operation terminates
normally. Otherwise, the transaction is rolled back (as described below) and the
TRANSACTION_ROLLEDBACK standard exception is raised.
If the report_heuristics parameter is true, the Transaction Service will report inconsistent
or possibly inconsistent outcomes using the HeuristicMixed and HeuristicHazard
exceptions. A Transaction Service implementation may optionally use the Event Service to
report heuristic decisions.
The commit operation may rollback the transaction if there are subtransactions of the
transaction that have not themselves been committed or rolled back or if there are
existing or potential activities associated with the transaction that have not completed.
The nature and extent of such error checking is implementation-dependent.
When a top-level transaction is committed, all changes to recoverable objects made in
the scope of this transaction are made permanent and visible to other transactions or
clients. When a subtransaction is committed, the changes are made visible to other
related transactions as appropriate to the degree of isolation enforced by the resources.
public void proceed_commit()
This operation is used to apply the commit for sub transactions
public void proceed_rollback()
This operation is used to rollback a transaction.
public void removeItself()
This operation is used to remove this object from POA
public void rollback()
The transaction is rolled back.
When a transaction is rolled back, all changes to recoverable objects made in the scope
of this transaction (including changes made by descendant transactions) are rolled
back. All resources locked by the transaction are made available to other transactions
as appropriate to the degree of isolation enforced by the resources.
