Not sure if this has been mentioned some where, but it used to be that
UNIX would lower priority of processes that had accumulated a lot of CPU
time. So the Oracle Background processes would get lower priority over
time. Stopping and starting an instance will fix this again ;-)

Anjo - The way that I would put it is that the operating system (any
multitasking o.s.) must make a decision on which process to give which
processor next and for how long. It is more complex than the o.s. just
picking the highest priority process from the run queue (processes that are

Hi all,
I'd like to run a file (r2) at 15:10 Apr 2. Below was

I tried EOF according to the on-line doc, and also
try control-C or a period or a control-D

I do not understand the difference between these two commands:
script_file log_file
script_file | tee log_file
As I understand, the first runs and redirects its standard output to a log
file. The second runs and pipes its standard output to the tee command,
which copies its
The tee command simply does what you say: it writes a copy to a file
as well as writing it to the console. You could get a similar result by
tail -f log_file
script_file log_file
Are you writing a script that needs to have two stream outputs? Or is it
important that you watch the script as it
The TEE command basically duplicates the output. It sends a copy to the
file specified and a copy to the standard output. This is the difference in
just redirecting it. When you redirect it, none goes to standard out, just
to the file specified.

tee copies its standard input to its standard output AND the log_file.

I do not understand the difference between these two commands:

The tee command duplicates its input, sending one copy to the file, and the
other to the screen (or the next command in the pipe).
You get to see your data and save it too.

This is from the HP-UX man page for tee:
DESCRIPTION
The tee command transcribes the standard input to the standard output
and makes copies in the files.
What this means in relative English is that the output is recorded to a file
(as in script_file log_file) but you see it

tee copies it's standard input both to standard output and the file. You can
see what it does and have a log file after that.
BTW man tee is faster than putting this onto the list
