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
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.
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??
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
One tip for those who are new.... "Do not skip".

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
Today is my exam😅
Same here 😢
Thanks 😊
Thank you so much sir.

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.
Thanx ❤
Sher exam se 2 din pahle aata h or gate Smasher ka vdeo dekh k pass kr jata h 😊😅
sir can you also explain 2 phase Commit Protocol?
Sir Explain Multiple mode locking schema and add in this series
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??
Sir according to you locking and shrinking phase starts and end together but in last table when T1 is shrinking but T2 is growing

Watching this before 20min of exam

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