Equivalent of alloc_oages in solaris 10

Hi All,
Currently iam porting my linux 10 gig network driver into solaris .
I have a question regarding Memory allocation ,
1. For performance tuning we directly allocate pages in linux
( using alloc_pages) and just unmap them ( using pci_umap)
Is there any equivalent in solaris .
2. Is there any sample driver which implemented this paging
mechanism .
Ramya

Thank you alan
even after setting the max file descriptor to 8192, the output from pfiles show as 4096
Current rlimit: 4096 file descriptors
would you know if there is something wrong with the command which i am using - projmod -s -K 'process.max-file-descriptor=(basic,8192,deny)' PROJECTNAME( I am issuing this command as root)
thank you

NLS_LANG Equivalent on the Solaris Machine

What the equivalent Enviornmental Variable on Solaris for report6i

Hi,
Reports 6i also uses the same environment variable NLS_LANG as in windows.
You may want to set it in solaris using the command:
"setenv NLS_LANG "Traditional hinese_Taiwan.ZHT32CNS11643-86"

Hibernation in Solaris 10

Is there any hibernation facility which allows the machine to shutdown by saving the contents on the RAM on hard disk and allows user to resume the work from the point he left at (equivalent to Windows) in Solaris 10?

You can hunt around for frkit which is what we used to have to install for OpenSolaris to get that functionality. It works fine for later builds of OpenSolaris up to and including Solaris 11 release. After that you may or may not have issues.

Recursive ctags under solaris 10

Hi,
i am new to solaris development.
Under linux for recursive ctags we use " ctags -r .".
What will be the equivalent recursive ctags under solaris 10 ?
With thanks in advance,

I think writing to NTFS is nearly impossible (due to changes of the NTFS version, security stuff, and so on).
However reading from an <u>unencrypted</u> NTFS partition seems to be a possible thing. I do not know if a tool or a driver <u>already</u> exists but I think it is a possible task to write a tool that reads from NTFS partitions.
I think writing a tool that reads from UFS partitions under Windows is an easy task, too. I wrote such a tool for reading the EXT2 file system under Windows long time ago.

Confused about ZFS filesystems created with Solaris 11 Zone

Hello.
Installing a blank Zone in Solaris *10* with "zonepath=/export/zones/TESTvm01" just creates one zfs filesystem:
+"zfs list+
+...+
+rzpool/export/zones/TESTvm01 4.62G 31.3G 4.62G /export/zones/TESTvm01"+
Doing the same steps with Solaris *11* will ?create? more filesystems:
+"zfs list+
+...+
+rpool/export/zones/TESTvm05 335M 156G 32K /export/zones/TESTvm05+
+rpool/export/zones/TESTvm05/rpool 335M 156G 31K /rpool+
+rpool/export/zones/TESTvm05/rpool/ROOT 335M 156G 31K legacy+
+rpool/export/zones/TESTvm05/rpool/ROOT/solaris 335M 156G 310M /export/zones/TESTvm05/root+
+rpool/export/zones/TESTvm05/rpool/ROOT/solaris/var 24.4M 156G 23.5M /export/zones/TESTvm05/root/var+
+rpool/export/zones/TESTvm05/rpool/export 62K 156G 31K /export+
+rpool/export/zones/TESTvm05/rpool/export/home 31K 156G 31K /export/home"+
I dont understand why Solaris 11 is doing that. Just one FS (like in Solaris 10) would be better for my setup. I want to configure all created volumes by myself.
Is it possible to deactivate this automatic "feature"?

There are several reasons that it works like this, all guided by the simple idea "everything in a zone should work exactly like it does in the global zone, unless that is impractical." By having this layout we get:
* The same zfs administrative practices within a zone that are found in the global zone. This allows, for example, compression, encryption, etc. of parts of the zone.
* beadm(1M) and pkg(1) are able to create boot environments within the zone, thus making it easy to keep the global zone software in sync with non-global zone software as the system is updated (equivalent of patching in Solaris 10). Note that when Solaris 11 updates the kernel, core libraries, and perhaps other things, a new boot environment is automatically created (for the global zone and each zone) and the updates are done to the new boot environment(s). Thus, you get the benefits that Live Upgrade offered without the severe headaches that sometimes come with Live Upgrade.
* The ability to have a separate /var file system. This is required by policies at some large customers, such as the US Department of Defense via the DISA STIG.
* The ability to perform a p2v of a global zone into a zone (see solaris(5) for examples) without losing the dataset hierarchy or properties (e.g. compression, etc.) set on datasets in that hierarchy.
When this dataset hierarchy is combined with the fact that the ZFS namespace is virtualized in a zone (a feature called "dataset aliasing"), you see the same hierarchy in the zone that you would see in the global zone. Thus, you don't have confusing output from df saying that / is mounted on / and such.
Because there is integration between pkg, beadm, zones, and zfs, there is no way to disable this behavior. You can remove and optionally replace /export with something else if you wish.
If your goal is to prevent zone administrators from altering the dataset hierarchy, you may be able to accomplish this with immutable zones (see zones admin guide or file-mac-profile in zonecfg(1M)). This will have other effects as well, such as making all or most of the zone unwritable. If needed, you can add fs or dataset resources which will not be subject to file-mac-profile and as such will be writable.

Is there a photo voltaic power source component for multisim 11?

i am looking for a component for a photovoltaic cell source.does multisim 11 have anything like this.

the best explination of the curcuit equivalent of a photo(solar cell) seems to be found in wiki
solar cell perameters to out put current and voltage
I = output current (amperes)
IL = photogenerated current (amperes)
V = voltage across the output terminals (volts)
RS = series resistance (Ω).
I0 = reverse saturation current (amperes)
n = diode ideality factor (1 for an ideal diode)
q = elementary charge
k = Boltzmann's constant
T = absolute temperature
RSH = shunt resistance (Ω)
then the edffected based on physical size of the cell
J = current density (amperes/cm2)
JL = photogenerated current density (amperes/cm2)
J0 = reverse saturation current density
(amperes/cm2)
rS = specific series resistance (Ω-cm2)
rSH = specific shunt resistance (Ω-cm2).
not sure if this helps i will check with my professor on this matter as well.

Solaris equivalent of kill -16 in linux

i am running a process in solaris 9(console) . i know its pid . To halt the process i have given "kill -16 pidvalue" . This halts the process . Later when i gave the same command (ie . kill -16 pidvalue )it resumes (continues)the process .
While giving the same command ( ie . kill -16 pidvalue ) in Linux the process corresponding to the pid value gets permanantly killed ( ie the process becomes nonexistant ) , so next time when i am giving the command (kill -16 pidvalue) in Linux i get an error message on console which says " process is nonexistant " .
So can u suggest the appropriate numeric value or alphabet which should follow kill to halt the process in Linux. In a way i am looking for "solaris equivalent of kill -16 in linux ".

kill -STOP
kill -CONT
should work on both.
I don't know why -16 (USR1) would work on Solaris 9.

Accounting Software - Solar Accounts Equivalent?

Currently I am using Solar Accounts via Bootcamp. I have to say I hate using Windows 7 on my Macbook Pro - just so clunky and the trackpad interfacing is awful.
I'm looking at Moneyworks - and have dabbled with Nano Accounts - though that has issues as yet not resolved for Snow Leopard.
I would LOVE a Mac equivalent of Solar Accounts - and I'm sure i would not be alone.
Is there anything out there yet that is similar to Solar Accounts for Mac that I may have missed?

Hi there - I was looking for a computer based system as I'm not always online. Plus the cost of those is quite high and cumulative!

Solaris 8 (I know not 9): Equivalent "GHOST" or "Ignite" product?

Is there any product for Solaris 8 that is similar to the "Ghost" product for PCs OR for HP-UX's Ignite product. We use both of these products here at work but will be getting a Blade 100 system with Solaris 8 on it and I want to be able to image it COMPLETELY in the event it crashes since it will be the only Solaris system we have. I want the image to be an absolute exact duplicate of its entirety for that boot disk.
For example, we use HP's Ignite product to perform an entire mirror of the drive back to tape. So all you do in the event of like the boot disk going out is replace the drive, put the DAT tape in the tape drive, boot up off of that tape and the ENTIRE VG00 is restored. I mean EVERYTHING in VG00.
Anything like that for Solaris?
Thanks, please write.
Angie

There are a Flar Archive format, this format is similar to ignite or mksysb but you need a jumpstart server (like ignite server or NIM server), or when you are reinstalling from CD select the Flash install.
See in blue prints for jumpstart
and the man page of "flarcreate".

Equivalent of sys/ptrace.h on Solaris 10

HI,
We are using the <sys/ptrace.h> as par to our shell scripts. This file, <sys/ptrace.h> is supported both on Linux and Solaris 8.
But somehow it's missing in Solaris 10 and I heard it's supported. Is it true??
Please could somebody who has worked on this provide what could be the alternative to this.
Thanks for you time.

#prstat -a will show you the top processes, while use /usr/ucb/ps -auxww to list all the running processes.
you will be able to see what is causing 100% CPU Usage.
you can also check with #iostat -xcn 2 to view disk performance statistics
In recent days I got the similar issue with Solaris 10 on SPARC Platform. where the top process were regarding our transaction switching middleware application when we align our application team they found multiple network connections were coming. Multiple unwanted connections were causing 100% CPU sys utilization.
to view connections we used snoop.
Hope this help.

PostThreadMessage, PeekMessage equivalent for solaris

Hi all,
Iam new to porting and have been trying to find out solaris specific Cpp(or C) APIs for some of the win32 APIs for Thread handling. All these APIs are in the windows.h header.
PostThreadMessage
PeekMessage
GetMessage
DispatchMessage.
and if I am not too much ambitious can you people point me to some documentation which talks about the windows.h file and solaris implementation for the APIs in that file?
Thanks in advance,

Sysdef command in Solaris 10.

Hi All,
sysdef command in Solaris 10 ( 5.10, s10_58 ) no more reports the message queue related Kernel
parameters i.e msgsys:msginfo_msgmax ( MSGMAX ) etc. For more info refer the link below :
http://docs.sun.com/db/doc/816-7137/6md5paukq?a=view
Since sysdef command no more reports the above parameters, what is the other way we can get the
same in Solaris 10? We have written our script in such a way that it greps for MSGMAX from the outcome
of sysdef and gets its value and perform certain operations. Quick reply would be greatly appreciated.
Thanks

We have written our script in such
a way that it greps for MSGMAX from the outcome
of sysdef and gets its value and perform certain
operations. Quick reply would be greatly appreciated.msgmax (maximum per-message size) has been removed completely -- there is no equivalent on Solaris 10. Instead, the
maximum total bytes on the queue, process.max-msg-qbytes (previously msginfo_msgmnb) is the only restriction on what can be placed in a SysV message queue.
To retrieve the current value of this in a script, you can use:prctl -P -n process.max-msg-qbytes -t privileged $$ | tail -1 | read x x value x x xNote that this is no longer a system-wide tunable -- the administrator can control this on a per-project basis. (see projects(1))

Solaris 10 X86 kernel patch 118844-30 ... probably bad

I installed the patch on some Dells. Seemed to run fine.
Actually, I installed 121127-01, 113000-07, and 118344-06
first since they were required by 118844-30.
Some problems have now turned up.
1. When you power cycle one of the patched machines they
refuse to boot with
Warning - The following files in / differ from the boot archive:
/boot/solaris/bootenv.rc
to continue booting .. #svc clear system/boot-archive
and then demand the root password.
2. Randomly, when you do a reboot, a patched machine will claim
that the hardware has changed and demand that you run
kdmconfig. Simply going in and out of kdmconfig, without
changes, does the job. Weird.
3. I went to patch the next machine and after the patch
install and reboot, it was a total brick, with the error
File not executable
Panic : No entry point in kernel/unix
Press any key to reboot
And, naturally, this patch cannot be backed out. For yucks
I tried the equivalent patches on a sparc. No problems. So
I think Sun effed up the GRUB stuff in the kernel patch

Ok ... I noticed that deep down in the README for the patch
they say to do a "reboot -r". Cute. We'll try that.
That seemed to go ok, but when I tried a power cycle, it
wouldn't boot, claiming
SMF database integrity check of /etc/svc/repository.db
failed making me run
/lib/svc/bin/restore_repository
which turned out to be a struggle.
My advice - stay FAR AWAY from this patch. At minumum,
it makes the power up boot process VERY delicate. Wait
for the -32 rev, which I predict will not be long in coming.
Thank you sun.
