8). Table : Transaction T1

Time shot
Transaction Step
Actions
Time-1
Read (A,a1)
Read current employee’s load balance.
Time-2
a1:= a1 – 500
Debit the Account by INR 500
Time-3
Write(A,a1)
Write the new loan balance
Time-4
Read (B,b1)
Read the current account payable balance
Time-5
b1 := b1 + 500
Credit the account balance by INR 500
Time-6
Write(B,b1)
Write the new balance
Time-7
Commit T1
Commit entire transaction

Consider the transaction as above Table to create log entries for immediate updates. Suppose, that a failure occurs just after the transaction log record for action Write(B,b1) has been Written.
a). Show the Contents of transaction log at the time of failure.
b). What action is necessary and Why?
c). What are the Resulting value of A and B?


9). Consider the transaction as above Table to create log entries for deferred updates. Suppose, that a failure occurs just after the record is written to the transaction log?
a). Show the Contents of transaction log at the time of failure.
b). What action is necessary and Why?
c). What are the Resulting value of A and B?


10).  Consider the following Transaction Step for Immediate Update Technique. 
Initial Value of A=1000, B=2000 and C=700.
         
Transaction Step
Actions
Begin Transaction T1
Start Transaction T1
            Read (A)
Read Value A
            A:= A – 50
Deduct 50 from A
            Write(A)
Write the new value of A
            Read (B)
Read the Value of B
            B := B + 50
Add 50 to B
            Write(B)
Write the new value of B
End Transaction
Commit entire transaction T1
Begin Transaction T2
Start Transaction T2
           Read (C)
Read Value of C
           C:=C-100
Deduct 100 from C
           Write (C)
Write the new value for C
End Transaction T2
Commit Entrire transaction T2

  • Create Log entries for Above transaction steps.
  • Let us Assume that the crash occurs just after the log record for step write(B) of transaction T1 then
    • What action is necessary and why?
    • What are the resulting value of A and B
  • Let us Assume that Crash comes just after the log record for the Wrtite(C) of Transaction T2 then
    • What action is necessary and Why?
    • What are the resulting value of A and B?
  • Finally, Let us Assume that Crash occurs just after the log record for Transaction T2,Commit
    • What action is necessary and Why?
    • What are the resulting value of A and B?  
11). Consider the following log entries.
Log Entries
T1,Start
T1,A,5000,4500
T1,Commit
Checkpoint
T2,Start
T2,B,1000,1050
T2,C,4000,3900
T2,Commit
T3,Start
T3,D,2500,2000
T4,Start
T4,E,1000,1200
T4,F,1200,1400

Suppose, that system crash is occurs after the last write entry of F of transaction T4 
then What action is necessary and why?        

----------------------------------------------------------------------------------------------------------------------------------------------
 Q-2. Differentiate the following :
1). Deferred Update Vs Immediate Update
2). Rollforward Vs Rollback
3). Stable Storage Vs Disk
4). Volatile Storage Vs Non-Volatile Storage
5). System Crash Vs Media Failure
-----------------------------------------------------------------------------------------------------------------------------------------------

Q-3. Answer the following in One line?
1) If the buffer pool is large enough that uncommited data are never forced to disk, is UNDO still necessary?
2) How about REDO?
3) If updates are always forced to disk when a transaction is performed, is UNDO still necessary?
4) How about REDO?
5) After a soft crash, where in the log should Analysis start?
