Thanks.

Solaris 10:

If you want to count number of processes in the Interactive class
casued by interactively logged on users.

ps -elc | grep IA | wc -l

Default number of user procs is 29.995
youll need a 100 MB Ram per user
each JDS user will run an average of 35 processes

29995/35 = 857 users *100 MB = 86 GB Ram

therefore the smallest machine where this can become a concern
is a SunFire 2900 with 12 ultrasparc IV CPU and 96 GB ram.

is there a way to customize F1, F2, F3 etc. with commands like ps -ef?

I'm getting tired to write commands like "ps -ef | more" or "ls -ltr".
(Yes, I know I can specify aliases).

SUN Solaris 8 with SUN Keyboard
SUN Ultra 5

There is when you're using bash or tcsh.

To map F6 to "ps -ef" in tcsh, use the bindkey built-in:

$ bindkey -c ^[[17~ "ps -ef"

To enter the F6 key sequence, press "control-v F6". Obviously,
this can be placed in your start-up file (.cshrc).

In bash, the same is achieved through the "bind" built-in. Use "read"
to find the key sequence emitted by F6

$ read
^[[17~

The ^[ is the ESC character, which in bash is represented by
\e (backslash e), so to map F6 onto "ps -ef" you'd type:

$ bind '"\e[17~": "ps -ef^M"'

(Press "control-v control-m" to enter the Return.)

On start-up, bash reads the ~/.inputrc file to map keys or character
sequences to shell commands.

Take care,

A very apt subject. Anyone recognizing their question for what it is
like that deserves help :), so at the risk of helping a competitor,
doesn't Sun include CPU profiling tools with the OS? I would think
that with a little luck, you could take a profile of the kernel and
see how much CPU was being consumed by SW RAID routines. You then make
the broad handwaving ass-u-me-ption that a HW RAID controller would
make all of that go poof. And perhaps a little bit more since the
multiple I/Os to the JBODs for RAID writes would also go poof,
becoming "hidden" behind the HW RAID controller.

I have doubts about this. ISTR, that you said that CPU was maxed out. Unless

the system is devoting CPU time to Software RAID; e.g. SVM or Veritas,

hardware RAID is unlikely do do a thing for you! If you, in fact, relieve an

IO bottleneck with hardware RAID, you'll just be throwing more load on the

CPU and/or memory.

Additional CPUs are not guaranteed to help either. If the application is not

such that it can run in multiple processes, or it can't use threads,

additional CPUs won't be much help.

How long is a piece of string? Twice the distance from the middle to either

end!!

BTW, didn't the customer also by the cheapest machine they thought would do

the job? IMHO, when you buy a new machine it should have sufficient capacity

to handle at least three years of anticpated growth. When you outgrow it, it

becomes your test and development system and you buy a new box for

production.

Well, the theory is that significant processing time IS being spent on
Solaris Volume Manager. But I'm trying to get a feel - from Sun, from this
peer group, anywhere really - on a typical amount.

I'm not sure I buy the second part of your argument. Funnily enough it's a
paraphrase of what the customer said: "I'd be disappointed if we don't see
at least 10% idle time at peak". What you say of course is true as far as
you go - the cpus may take up the slakc to their limit with other types of
activity - but overall you'd expect the peaks to fewer and shorter.

BTW, didn't the customer also by the cheapest machine they thought would

They bought the box, then adequate, last summer but didn't anticipate the
growth!

All true but the output of svcs -a does not tell you which service is
the removable media service.

If SUN chose a self descriptive name that would not matter.

If all you have is "smserver" you would probably not guess removable
media. I would guess sado/maso porn server. ( Not that I am into that
).

I suppose I will just write a little shell script that generates a list
of all the services, does a svcs -l on each one and picks out the
english description. That will have the same net effect.

Hi, I have read some/most of the USB/firewire posts and and based on
the experiences of others, decided to give it a shot. I needed alot
more storage and SCSI storage was kinda out of the question basewd on
the amount of storage needed.
The Solaris experience wasn't as clean as that of the MAC, but I am
glad to say that this stuff does work. The USB interface works better
than does the firewire. At least for me it does.

I think thats the case for everyone.

The good:
- It works. I increased the strorage capacity of my Ultra 60 for alot
cheaper than purchasing equivalent sized SCSI drives. Speed is not an
issue for what I plan on storing on the drives. The USB drives are for
long term backup of lots of data. Will eventually go with 500gb drives
once the prices on those drives come down a bit.
- Can now swap in and out drives as need be without rebooting.
The bad::
- Using the USB interface, I can't have the unit powered on when
Soalris is booting. When I do, a message appears that says soemthing to
the effect that it can't connect to the device sitting at the other end
of the USB interface. After Solaris comes up, I can then turn the unit
on and it will see the drives. Both of them.

That could be your "tower"s busted firmware? I built up a Promise tower
last year (non USB admittedly) - had to turn off all RAID on it and
set the powerup state to "JBOD" - then used smc to configure it.
Even then the "LUNS" were restricted to 400 GB
So 2 were made instead of 1. Been in production for about a year now.

My direct attached stand alone USB drive has to be turned on first or
I cant mount it as a regular disk..

vfstab entry:
/dev/dsk/c3t0d0s0 /dev/rdsk/c3t0d0s0 /ion_160 ufs
1 yes -

- I can't have vold running. When vold is running, I can't see the
drives at all.

Again it could be broken firmware. I have vold running no problem

- Can't use the firewire interface. When I do, I can only see 1 of the
drives. Driver problem?

Maybe. I doubt its worth the bother to get FW going if USB works OK.

- When using the firewire interface, when I reboot Solaris and the unit
is powered on, I get a kernel panic. So I'm sticking with USB for now.

Thats expected behaviour on Solaris 10. Only 1 device is supported I
believe and thats a camera.. : > Im surprised it doesnt panic ANY time
you turn it on. but then Im using a Blade 1000/2000.

Maybe the next release of Solaris will correct the problem? If I wanted
to use the firewire interface, then I have to power the unit on after
Soalris has been booted.

You can try Nevada (Solaris 11) drivers - they worked for me.

yes, that's OK. But the printed line is generated by the executable
a.out, which doesn't fork at all...

You don't understand; "a.out" may not fork() but the way the
pipe line is constructed the shell fork()s and then runs a.out
*in the parent*.

Like this:

if (fork() == 0) { /* Ok, start building pipe - child of shell */

pipe();
switch (fork()) {
case: 0 /* Child */
/* setup pipe */
/* run the first process in the pipeline */
exec(...)
_exit(1);
default: /* Parent */
/* setup pipe */
/* run the second process in the pipeline */
exec("a.out");
_exit(1);
case -1: perror("fork");
}
}

So the shell forks in the subprocess to build the pipeline; and then
uses that subprocess to execute the last process in the pipe (a.out).
That last process then has the other process as child.

sh -> a.out -> other process

and not what you might expect:

sh -> other process
-> a.out

You don't understand; "a.out" may not fork() but the way the

*in the parent*.

I did understand what you mean. I just wanted to point out that this
kind of behavior is a little bit surprising, as a.out shouldn't need to
be aware of the context it is living in. But that seems to be an invalid
assumption on my part. As I pointed out in my other posts, /bin/sh seems
to be the only one surprising its children with this odd kind of
implementation. I agree, you save on fork. But I really care about the
unexpected gift of getting a pid from calling wait, when I wouldn't
expect it to return something else than -1.

BTW: I just x-checked /usr/xpg4/bin/sh: it returns -1. In contrast,
OSF1's /bin/sh behaves the same way as the one of Solaris.

Thanks anyway for your clarification. I guess I will have to go and
review some code concerning this issue...

Cheers,
Tom

Solaris' /bin/sh is different to ksh, bash, and zsh in this respect.
This is really confusing. Do I guess correctly that this is one of the
/bin/sh oddities that some people might rely on and that cannot be
changed because of backward compatibility guarantees?

Thanks,
Tom
