This is an unusual situation and is normally due to a system
failure, storage device failure, disk full condition, thread
interrupt, or a bug of some kind. When a transaction is in this
state, the Environment will have been
invalidated by the error.
In a replicated environment, a transaction in this state is not transferred to replicas. If it turns out that the transaction is indeed durable, it will be transferred to replicas via normal replication mechanisms when the Environment is re-opened.
commit method throws an exception and the
transaction is in the
POSSIBLY_COMMITTED state, some
applications may wish to perform a data query to determine whether
the transaction is durable or not. Note that in the event of a
system level failure, the reads themselves may be unreliable, e.g.
the data may be in the file system cache but not on disk. Other
applications may wish to repeat the transaction unconditionally,
after resolving the error condition, particularly when the set of
operations in the transaction is designed to be idempotent.
public static final Transaction.State COMMITTED
Note that a transaction may be in this state even when an exception
is thrown by the
commit method. For example, in a
replicated environment, an
InsufficientAcksException may be thrown after
the transaction is committed locally.
