Why is this configuration wrong?

Selecciona una de las siguientes respuestas posibles:

  • A. You must choose an XA driver when a data source participates In global transactions.

  • B. "One' Phase Commit" always returns "ready" during phase one of the two-phase commit process’ so it is possible you will have heuristic errors in the database.

  • C. "One-Phase Commit" processes this data source last In the global transactions, if the EJB must go last, you cannot use this configuration.

  • D. "One-Phase Commit" only allows this data source to participate in global transaction, so you cannot have a global transaction that includes an EJB.
