Isolation level

[feci]

Hi,

where can I find some info about xaDisk supported isolation levels?

Hi Tomas,

With 1.1, here is how isolation is implemented during various
operations:

create(F) Exclusive lock on F (F is file or dir)
delete(F) Exclusive lock on F (F is file or dir)
move(F1, F2) Exclusive lock on F1/F2 (F1/F2 are file or dir)
write(F) Exclusive lock on F (F is file)
truncate(F) Exclusive lock on F (F is file)
read(F) Shared lock on F (F is file)
length(F) Shared lock on F (F is file)
exists(F) Shared lock on F (F is file or dir)
copy(F1, F2) Shared F1, Exclusive F2 (F1/F2 are file)

listFiles(D) Incurs No Locking.


Hope that helps.


Thanks,
Nitin
