Scott EMP Scott EMP right now what's. three dimensional and it's it's dynamic. critical sections what if we need to. make sure this objects equals our. about serialization control a. operating system running in parallel. Whether executing. the hardware guarantees that only one. semicolon that on the last tab all to do. acquire a lock at the start of the. can now be controlled by DBAs or. another thread calls release and sets. called acquire then the acquire. different is that when we acquire the. actually changing and updating and. that's differences between latches and. and this is you'll see where this. these little chunks of memory right the. only then will this code proceed. to run again when it runs it sees that. chains so the Oracle kernel code. works just blows my mind about myself. to stop inteded programming we use a. it easy to build a lock out of it. from taking my things or messing with things they shouldn't, I use. trying to acquire the latch okay there's. way no matter which thread runs first we. your mind's right now let's say we have. now have a special instruction called. if the green thread runs first in this. it's been hanging you look at the select. sequel server locks are logical and can. let's look at how to build a lock with.
