Re: Is enq: TX - row lock contention a wait or syscall

To reduce it even further, everything is just a sequence of ones and zeroes, unless we're talking a quantum computer. I am not sure whether Oracle can run on quantum computer and what kind of logic do quantum computer use. I am not sure that Boolean logic and K-tables are applicable in the world of quantum computers. And maybe quantum computers will present themselves as 16 THZ 64 core x86_512? Although I do hope that when 512 bit processors come into play, something newer than x86 architecture will be available. Despite that, it would probably be fun to work on 4 PB laptop running Windows 2048 on 128 core X86_512 CPU. Having been born in 1961, I will probably not have an opportunity to explore ORA-00600 and ORA-07445 on Oracle 2048.
