execute(TwoPhaseCommit... objects)
Executes a 2-phase commit algorithm by first
TwoPhaseCommit.prepareCommit() all objects and only if all succeed,
it proceeds with TwoPhaseCommit.commit() . |
public static void execute(TwoPhaseCommit... objects) throws TwoPhaseCommitTool.PrepareCommitFailException, TwoPhaseCommitTool.CommitFailException
TwoPhaseCommit.prepareCommit()
all objects and only if all succeed,
it proceeds with TwoPhaseCommit.commit()
. If any of the objects
fail on either the preparation or actual commit, it terminates and
TwoPhaseCommit.rollback()
all of them.
NOTE: it may happen that an object fails to commit, after few have already successfully committed. This tool will still issue a rollback instruction on them as well, but depending on the implementation, it may not have any effect.
NOTE: if any of the objects are null
, this method simply
skips over them.
TwoPhaseCommitTool.PrepareCommitFailException
- if any of the objects fail to
TwoPhaseCommit.prepareCommit()
TwoPhaseCommitTool.CommitFailException
