Tamil,

thanx for the reply. What you have told me that I know and its is very standard one. I think you have not gone through my questions properly.

q1> deadlock is due to row-level locking or transaction layer locking?
How to understand whether it is row-level locking or transaction
layer locking?

q2> What I have pasted , that is 100% correct. '/' is there in rowid.
Since it is starnge to me , that's why I am asking.

Regards

Deba
