PLSQL... Script: Scrivere su un file


A User Agent, like a web browser, uses HTTP to request a HTML document



In programming the danger of exploring the small details of coding is that you get obsessed with every line of code you write, thereby greatly reducing productivity.
In general, is not worth obsessing over code.
On the other hand you should code with deliberation and intent. Steven Feurstein Oracle Magazine July /August 2004

# in this example the server has 8 processor: processor from 0 to 7
.
# I also use to assume the number and type of CPUs using the following formula:
total number of process (from 0 to 7) divided the number of physical id (0 and 1).

So doing the math on this example:


8 / 2 = 2

It means the server got 2 Quadricore CPUs
