  1. The transaction manager writes the transaction commit record to the transaction manager log file.

  2. The transaction manager initiates phase two of the two-phase commit process. The transaction manager sends an xa_commit_entry message, in parallel, to each enlisted XA resource manager.

  3. The resource manager commits and then replies to the xa_commit_entry message.

  4. When all the resource managers on the system complete phase two, the transaction manager writes a forget record to its log file. Optionally, the transaction manager can do a lazy log file write to economize on log I/Os. The transaction manager then forgets the transaction.
