prepare(gid)
Initiates the beginning of a two-phase commit. A global identifier parameter is required, which is a value unique across all processes involved in the commit. It must be a string of DB_GID_SIZE bytes. More info...
discard()

This method frees up all the per-process resources associated with the specified transaction, neither committing nor aborting the transaction. The transaction will be keep in “unresolved” state. This call may be used only after calls to “dbenv.txn_recover()”. A “unresolved” transaction will be returned again thru new calls to “dbenv.txn_recover()”.

For example, when there are multiple global transaction managers recovering transactions in a single Berkeley DB environment, any transactions returned by “dbenv.txn_recover()” that are not handled by the current global transaction manager should be discarded using “txn.discard()”.
