Ur teaching skill is awesome just one small confusion. Transaction T2 has never acquired any lock on B then how could it unlock or release the lock on B ? In T2 column, at the end u have written unlock(B) it must be unlock(D), right? 8:20
Sir Below serializability word After X(a) of T1 ,T2 wants S(A) in such case as you explained ,that T2 of S(A) should wait for unlock of x(a) in T1,but you didn't mentioned that T2 will be blocked , While in right side table : First t1 has S(a) and after that if in case t2 wants X(a) then you explained that t2 will be blocked (not mentioned wait),so I am getting confused when exclusive lock over shared lock occur or vice-versa lock ,then t2 should wait or blocked
Hey I just wanted to know if I could get a further explanation as to why in the second example of T1, T2 the T2 could start its growing phase but in the previous example T2 could not start its growing phase till T1 finished their own growing phase? Thank you
In the last example, what happens if T2 starts its growing phase as it first asks for Shared lock (A), and then later, before the shrinking phase of T1 has started, it asks for an Exclusive lock(A)? Will it wait or will its growing phase be terminated??
Shrinking phase is dependent on particular transaction, if transaction t1 is done with shrinking phase t2 has nothing to do with it. Hence I feel lock of D is correct.
One tip for those who are new.... "Do not skip".
Content of every second is different and informative.
Ok
yes
it is not different but the way sir teaching far different and easy than my college teachers because they are for making things complicated and this sir for making things easy for student like us .

Sir Below serializability word
After X(a) of T1 ,T2 wants S(A) in such case as you explained ,that T2 of S(A) should wait for unlock of x(a) in T1,but you didn't mentioned that T2 will be blocked ,
While in right side table :
First t1 has S(a) and after that if in case t2 wants X(a) then you explained that t2 will be blocked (not mentioned wait),so I am getting confused when exclusive lock over shared lock occur or vice-versa lock ,then t2 should wait or blocked
Great sir.
Sir please also upload videos on digital electronic (sequential circuit)
Thank you
V great sir g
Thank you so much sir.
Thanku sir❤️

Nice
Tq sir
Yrr kya padhate hai ye banda!!!!!

Waah
the best way to prep or review the subject for me is to put on the Gate Smaschers playlist and skim at 2x speed...
Efficiencey : 100

Thanx ❤
Hey I just wanted to know if I could get a further explanation as to why in the second example of T1, T2 the T2 could start its growing phase but in the previous example T2 could not start its growing phase till T1 finished their own growing phase? Thank you
Tomorrow is my exam😂
After one hour is my exam 😂
Mine today
Same yrr
Sir according to you locking and shrinking phase starts and end together but in last table when T1 is shrinking but T2 is growing
In the last example, what happens if T2 starts its growing phase as it first asks for Shared lock (A), and then later, before the shrinking phase of T1 has started, it asks for an Exclusive lock(A)? Will it wait or will its growing phase be terminated??
Jaa rhe h bhaiya tumhare bharose
All the best
Thanks .....
i have no idea what hes saying, but it kinda helped???
Semester k hardly 20 days bache hai
Aur hum idhar aye hai concept clear karne
Kiun ki college mai to syllabus khatam kia nehi 😅😅
👍👍
Sir plz add video of net exam questions..
Lock based protocol=2 phase locking protocol same hai kyaaa????
Sher exam se 2 din pahle aata h or gate Smasher ka vdeo dekh k pass kr jata h 😊😅
Today is my exam😅
Same here 😢
Sir,in last table t2 transaction unlock D comes right?
Yes dude
Shrinking phase is dependent on particular transaction, if transaction t1 is done with shrinking phase t2 has nothing to do with it. Hence I feel lock of D is correct.
sir how is this schedule serializable when we have allowed t2 to get shared lock?
COETA 🔥
