Examples of com.sleepycat.db.Transaction.commit()

com.sleepycat.db.Transaction.commit()
End the transaction. If the environment is configured for synchronous commit, the transaction will be committed synchronously to stable storage before the call returns. This means the transaction will exhibit all of the ACID (atomicity, consistency, isolation, and durability) properties.
If the environment is not configured for synchronous commit, the commit will not necessarily have been committed to stable storage before the call returns. This means the transaction will exhibit the ACI (atomicity, consistency, and isolation) properties, but not D (durability); that is, database integrity will be maintained, but it is possible this transaction may be undone during recovery.
In the case of nested transactions, if the transaction is a parent transaction, committing the parent transaction causes all unresolved children of the parent to be committed. In the case of nested transactions, if the transaction is a child transaction, its locks are not released, but are acquired by its parent. Although the commit of the child transaction will succeed, the actual resolution of the child transaction is postponed until the parent transaction is committed or aborted; that is, if its parent transaction commits, it will be committed; and if its parent transaction aborts, it will be aborted.
All cursors opened within the transaction must be closed before the transaction is committed.
After this method returns the {@link com.sleepycat.db.Transaction Transaction} handle may not beaccessed again, regardless of the method's success or failure. If the method encounters an error, the transaction and all child transactions of the transaction will have been aborted when the call returns.

@throws DatabaseException if a failure occurs.
