b If TS(Ti ) W-timestamp(Q), then the read operation is executed, and Rtimestamp(Q) is set to the maximum of R-timestamp(Q) and TS(Ti ) 2 Suppose that transaction Ti issues write(Q) a If TS(Ti ) < R-timestamp(Q), then the value of Q that Ti is producing was needed previously, and the system assumed that that value would never be produced Hence, the system rejects the write operation and rolls Ti back b If TS(Ti ) < W-timestamp(Q), then Ti is attempting to write an obsolete value of Q Hence, the system rejects this write operation and rolls Ti back c Otherwise, the system executes the write operation and sets W-timestamp(Q) to TS(Ti ) If a transaction Ti is rolled back by the concurrency-control scheme as result of issuance of either a read or write operation, the system assigns it a new timestamp and restarts it To illustrate this protocol, we consider transactions T14 and T15 Transaction T14 displays the contents of accounts A and B: T14 : read(B); read(A); display(A + B) Transaction T15 transfers $50 from account A to account B, and then displays the contents of both: T15 : read(B); B := B 50; write(B); read(A); A := A + 50; write(A); display(A + B) In presenting schedules under the timestamp protocol, we shall assume that a transaction is assigned a timestamp immediately before its rst instruction Thus, in schedule 3 of Figure 1613, TS(T14 ) < TS(T15 ), and the schedule is possible under the timestamp protocol We note that the preceding execution can also be produced by the two-phase locking protocol There are, however, schedules that are possible under the two-phase locking protocol, but are not possible under the timestamp protocol, and vice versa (see Exercise 1620) The timestamp-ordering protocol ensures con ict serializability This is because con icting operations are processed in timestamp order The protocol ensures freedom from deadlock, since no transaction ever waits However, there is a possibility of starvation of long transactions if a sequence of con icting short transactions causes repeated restarting of the long transaction If. internet 500 upc UPC promocje 1zł | czerwiec 2019 | Oferta na Newsweek.pl

When doing circuit analysis with a network that contains resistors, we apply KCL and KVL using Ohm s law to relate the voltage to the current as necessary The best way to proceed is to look at some examples EXAMPLE 2-5 Find the three unknown currents shown in Fig 2-8 SOLUTION We will denote the voltage across each resistor R by VR First we apply KVL to each of the two panes or loops in the circuit Going in a clockwise direction, the loop on the left-hand side of Fig 2-8 gives 7 + V5 = 0 where V5 is the voltage across the 5 resistor in the center We conclude from KVL that V5 = 7 V Using Ohm s law (26) we can nd the current through the abonament net upc Optický pevný internet | UPC.cz
