As a longtime Linux user/admin and beginning Oracle DBA I now know that all memory should be occupied by Oracle, not by OS. :-)
Serious mode on: I'm sure it's a big problem to be narrow expert. They can be brilliant specialist in their field, but one step aside and they are absolutely helpless.
- illumin8 15y agoThanks for the great comment. I really wish more people like yourself at least understood Linux memory management. I think it will truly help you to be an exceptional DBA. I can also understand how an expert DBA might not know or care too much about the OS underneath his software, although I would argue that if you understand the OS fundamentals, you will be that much better at whatever specialty you have.
- ivan78 15y agoThank you. I'm on my way to become exceptional DBA. Oracle is only 2 years younger than me, but unfortunately it has been developing much faster than I am. It literally takes years just to become familiar with all these layers of Oracle technologies. So, it's really hard to blame DBAs for not knowing how underlying OS works. :-)
