Solaris 10 (5.11) Questions

I have read many posts that do not seem to relate to my system so I am trying to get answers here. I have several questions regarding root's environment settings, use of LD_LIBRARY_PATH, logging of general errors, and menu configurations. To me there does not seem to be a clear definition of solaris setup. Some of the information on the Sun site that appears to be related to my issue I cannot access. If this is "open" software I think there should be more information available.
1) I have changed root's shell to bash (I know some people think this is bad but I want the system to be usable) and given root a home (/root) in passwd file. I am using root in a terminal using "su".
a) I have added .bash_profile and .profile files in / and /root.
b) I have set values in /etc/profile and /usr/dt/config/dtspcdenv to no avail.
c) HELP! What files control root's environment? When I modify one of these files, what do I need to do to get the changes implemented when I use "su"?
2) LD_LIBRARY_PATH
a) I was trying VirtualBox (from a terminal as "su") and received errors about not finding libGL.so, so I wanted to change LD_LIBRARY_PATH to see what the affect would be.
b) My system had no LD_LIBRARY_PATH definition to start with (set and export did not show any settings)
c) Because of (2) I just created a LD_LIBRARY_PATH that pointed to the location of lbGL.so (in my primary user profile). When I logged in the next time, I got an error about nautlis not being able to start and suggested running bonobo-slay (I think this is the correct command) to correct the problem. It also mentioned that it could be a LD_LIBRARY_PATH setting. I think it mentioned "bonobo activation start files" but that message was not distinct enough for me to determine what path might be missing from LD_LIBRARY_PATH.
d) Searching on the net (using an MS Windows box) I found references to a couple of other paths that should be in LD_LIBRARY_PATH, so I added those and the system would let me login.
e) HELP! Can somebody define the use and setting of LD_LIBRARY_PATH? Is there any documentation for the operation of Solaris when LD_LIBRARY_PATH is not defined versus when it is defined?
3) Since I changed LD_LIBRAY_PATH, I cannot run the menu selection Preferences.Main Menu. I get a busy cursor and then nothing.
a) Obviously I could remove my definitions for LD_LIBRARY_PATH and it would probably work, but that does not help me understand what is happening.
b) I thought that if I ran the command from a terminal, I might see an error message that helped me fix the problem.
c) HELP! How do I know what command is run when I make that menu selection?
d) HELP! Are errors, that keep an application from running, logged any where? I have searched through /var/log files and found nothing.
4) Menu configurations
a) I believe I am running gnome and I have a java menu button on my task bar.
b) HELP! What determines the contents of this menu when I select it.
c) The gnome menu definitions seem to be a LOT more obscure than those for KDE.
d) HELP! Can anybody point me towards a thorough documentation of the gnome menu configuration?
Thanks,
wor

Wow. A gazillion questions in one.
As the other responder indicated, use `su -` to set the environment of root (the "-" is the key).
If you changed root's home directory to /root, then you don't need to add stuff to /. You just need to add it to /root. I've done the same sort of stuff, but I switched to ksh rather than bash.
You can use `crle` to see what the default libraries are that the loader will reference when there is no LD_LIBRARY_PATH. A `man crle` will actaully tell you quite a bit about the loader's actions.
In Solaris, many of the log files are in /var/adm. But, application specific stuff may not show up in the system logs.
You can find lots of documentation at http://docs.sun.com -- view it by browsing or searching. You should spend some time getting to know it so that you can find your way around in it. Also check man pages. You may not get all the man pages initially when you use `man ...` However, if you try `find / -type d -name man`, you will find the location of lots of other man directories. Then you can get specifics for them by doing `man -M /usr/sfw/share/man wget` (just as an example). The -M gets you into other man page directories.

New to Solaris - dual boot question

I have been using OpenSolaris on my ThinkPad T400s, dual booting with Windows 7. I want to give Solaris 10 a try. I've had it running in Virtual Box under OS X for a while, and I think I'm comfortable enough to try it out on my ThinkPad. Here is my question: will the Solaris Interactive installer let me install Solaris 10 in my existing OpenSolaris partition? And if it does, will it modify the bootloader so that I can still dual boot with Windows 7? I dont want to have to destroy partitions and re-install Windows. Once its on my hard drive, I can add myself as a user, install the Intel 5300 wireless driver, etc... Anyone have any other issues with Solaris 10 on a T400s?

Okay, well as usually happens, when I resort to help I end up solving my own problem.
In this case however, I still don't have a good grasp of what is going on.
I deleted the partition table with sgdisk --zap-all /dev/sda and then used gdisk to recreate it, specifically setting the code for /dev/sda1 to ef00.
I then reformatted the FAT partition, leaving the other one alone. After mounting /dev/sda1 to /boot and reinstalling linux and grub, I ran:
grub-install --target=x86_64-efi --efi-directory=$esp --bootloader-id=arch_grub --recheck
as described in the wiki, and
grub-mkconfig -o /boot/grub/grub.cfg
And it worked, including automatically detecting Windows on the other drive. Not sure what went wrong the first time but I'm glad to get it working.

New to Solaris (unix) - basic questions (please)

Hello!
I am completely new in Solaris World, and in fact in Linux too. All I can do (may be) is to walk throught dir tree. I have one big question and many many small ones. I've just installed Solaris 10 (writing this there), I am very happy and I don't know what to do. I hope you can give me some advice. Well, the big question is where to get information about how to do basic tasks I've been doing in windows?
The smaller questions (problems) is:
1) When I boot solaris it actually goes to console, and no window system (GNOME, CDE) appears. I've already been lucky for 2 times and I managed to launch windows by typing 'gnome-terminal', but it ofter respond with something and no window system lauched. Can I do so, that window system launched automatically?
2) I have primary partition on my hard drive with FAT 32 to share files with WindowsXP. Where can I see these files in Solaris (may be I should mount, how?)
3) How can I see files on my USB flash (how to mount)
4) Do I have to install drivers for my monitor(video card) in Solaris?
5) When I type 'man' its ok, but 'man ls' respond 'No manual entry for ls' (and all other commands. How to fix it?
6) Where I should store my files (doc, music etc. ). In windows its typically on different partitions (folders)
Thank you, and hoping for help.

Well you've a long road ahead. But heres a start:
Answer to Question 1) /usr/dt/bin/dtconfig -eQuestion 2) If there are FAT32 driver in Solaris 10 (There weren't to my knowledge in Sol9 or earlier) you would need to mount them.
'man mount'
Question 3) would be similar to the answer to question 2, although you may be able to configure autofs for it 'man autofs'
Question 4) Not necessarily, but to get full functionality of your video card, yes - see manufacturers website
Question 5) Your MANPATH environment variable is bad OR you did not install them .... try 'pkginfo SUNWman' if it returns anything but not found try 'MANPATH=/usr/man:/usr/share/man:/usr/sfw/man ;export MANPATH' You can add additionaly directories pointing to manpage install locations by adding a colon followed by the directory.. first off hit 'man man'
Question 6) Gnome will help once you get it going (see answer 1). Otherwise store it however you like, just don't let the root partition get full or you'll likely crash it.

10g RAC on Solaris 10 containers - Question on Approach

Hi All
To introduce a little, I am trying to set-up 10g RAC (active-active) on Solaris 10 Containers. For the disaster recovery site, I was considering an option for storage replication across datacenters. As I look at the situation where the database could be highly transactional, I wanted to go for this option hoping I might be better able to recover db on dr site if a failure happens and also alleviate some load from the prod servers. In this regard I have a set of questions for which if you could share your experiences, thoughts .. I am sure will help my preperation.
1 Is Oracle Supported on Solaris 10 containers? I believe it is not supported and ofcourse am getting into the certification matrix for this with oracle. Anyways, any work around tried out by anyone ?
2 Which product is better in terms of performance while co-existing and co-functioning with Oracle? Sun Cluster!!! Vertas Cluster!!! any other? I am unable to link to any recommendations from Oracle and hence trying to understand the generic or say standard approach to this.
3 I understand on Prod site, Oracle remains active-active on two node cluster while I will mirror my SAN between Prod site and DR site on a timely basis, while DB is up and running. This mirroring has to be only an asynchronous mirroring for some limitations. I am unsure about my recoverability if we need to switch over to DR. Will I be able to recover the Database to a point when my last mirroring has been completed successfully when I say the mirroring happened while the Prod db is up and running (hot backup type on disk level). Until now I used a cold backup for Storage replication and I was sure to bring it up there. This hot backup kind of attempt is raising unrest and questions about the abilities.. :-(
4 I also have come across a term called federated databases? Is it similar to what I am trying to achieve here? Storage level replocation across data centres?
I know it takes some time to get to the end of it and finally implement it, but your inputs will certainly help me get things straight before I hit this first click. Thanks for all your inputs, advices, suggestions. :-)
Regards!
Sarat

According to Oracle "Both Oracle 9i R2 and 10g R2 databases have been certified to run in a Solaris Container."
There are references here :- http://forums.sun.com/thread.jspa?threadID=5397695
"Oracle databases (RAC and non-RAC) have been certified to run in a global Solaris 10 Container"
What storage are you using ? (filesystem, ASM ?) Personally I prefer ASM now, but it does depend on the storage platform and backup strategy.
What backup infrastructure do you have ? RMAN backup directly to tape is better than file copy.
For DR standby purposes I would use Dataguard instead of disk mirroring / storage replication. It is much more flexible (e.g can switch direction of replication, do incremental backups from the standby etc).
I would use CRS instead of VCS. CRS is built for the job, and integrates with netca, dbca, etc for service management, and also integrates with Dataguard Broker for standby switchover.

Solaris 10 Patch Question

Assuming two identical systems installed side-by-side
and operated by the same owner. Both machines are
registered with Sun Microsystems and possess valid
licenses for Solaris 10. The owner has determined the
same Software Update (formerly called a �patch�) is
required for both systems. The SWU (Software Update)
is only available from Sun Microsystems. Only one of
the systems is covered by a Sun Service Plan that
provides access to the SWU, the other is a
self-maintained system without any service plans
whatsoever.
     System A     System B
Valid Solaris 10 License     yes     yes
Active Sun Service Plan     yes     no
Service Method     Sun Service Plan     Self Maintained
Questions:
Can SWU obtained from Sun for System A be used on
System B?
a.     if the SWU is only made available with a Sun Online
ID + Service Plan? (In other words, a �restricted� or
�behind-the-firewall� SWU)
b.     If the SWU is only made available with a Sun Online
ID? (In other words, a �public� SWU, such as a
hardware driver update).
c.     Will Sun accept time and materials POs for software
troubleshooting?
d.     Will Sun accept time and materials POs for hardware
troubleshooting?

No, it doesn't have an OBP, instead it uses a BIOS, which is quite different from the OBP.
Normally; doing init 0 on a x86 box will just bring you to a state where it offers to reboot.
On x86 you also have the "Configuration Assistant", which does some tasks which would be performed by the OBP on the SPARC architecture.

Solaris 10 installation - questions

Hello,
I'm going to install Solaris 06/06 on my PC. I have some questions about the installation and steps before the installation itself.
First of all, summarize of what I have:
PC checked by device detection tool and all necessary drivers that are not shipped with Solaris
160 GB hard disk - 100GB of NTFS partition with Windows XP, 60GB of "untouched" space - no filesystem, no created partition (is it ok this way? or rather create partition with raw data?)
I've read many discussion boards and web pages related to topic of coexistence of win XP and Solaris on one disk. It seems that XP and Solaris can work on one hard disk without problems.
However, I must admit little fears of possible problems - i.e. threat of corrupting of the access to ntfs partition or the ntfs partition itself. I'll backup all important data, that's without question, however losting of that partition would be very annoying. I have no possibility to make exact disk image.
I've noticed on the forums that grub, a solaris boot loader, sometimes doesn't include win xp partition in its menu. It could be added there, however I've noticed too that some people had big problems with this as they were unable to boot win xp from grup even though they added windows item to grup. This is the thing I fear most - I think that the correct setting during installation cannot corrupt other (in my case Win XP) partition but by installing grub, there is (according the posts on message boards) the chance of possible problems of cutting out Win XP from booting.
Could this be prevented or repaired by the backup of master boot record and in case the problems with booting will occur replace MBR modified by Solaris installation by the backup to back to the state when XP is booting automatically? If so, could you recommend any tool for MBR backup?
Thanks for any comments or advices.

Hello!
First of all,i don`t know any tool that u could use to make a backup of your MBR.
Anyway,dual booting is a problem that i have had in the past. In my opinion, Solaris and Windows will never run without problems (from the Windows point of view). I have tryied many versions of Unix/Linux toghether with Win XP (on the same system);there`s always some kind of problems...sooner or later.
Last week i have installed Solaris 10 toghether with Win XP on a PIII Compaq Deskpro.No problem at the begining.After 1 day, the WIn OS crashed (the PC blocks when i start WinXP).
So, in my opinion, if u want to have a fully functional Solaris system, install it on a separate PC,even if it`s an older one (for example, i have Solaris installed on a PIII/500 MHz/512 RAM bought with 50 euro - depends what u want to do with your Solaris system).
Good luck!
Best regards,
N.

Solaris Memory Allocation Questions

Hi,
I am a Columbia University engineering graduate student doing research on Solaris 10 Operating System. I just have 3 quick questions that I was unable to find answers for on the Sun Documentation website. If any1 can help me answer these questions or point me to resources that do I would really appreciate it. The questions are as follows.
1. Does Solaris 10 provide developers with methods to ask for memory that only programs running with a certain security key or privilege can access?
2. Also, can develops ask for private memory? I understand that during write on shared memories, copy-on-write will generate a copy of the shared memory page and make that private to the process but I am not sure if there are ways to allocate private memory at the beginning.
3. Does Solaris 10 provide developers with methods to ask for memory that is fixed in memory and not pageable? I understand that by asking for ISM then the pages are locked in memory. But I was wondering if there are methods that an application can call that does this without having to share memory.
Thanks,
Larry Chen

Solaris 10 changed everything to be based on process privileges (see the output of "ppriv -vp" for a list). It's not clear to me on a brief inspection which limits access to a processes address space but that is the mechanism.
2. Also, can develops ask for private memory? I understand that during write on shared memories, copy-on-write will generate a copy of the shared memory page and make that private to the process but I am not sure if there are ways to allocate private memory at the beginning.Anytime you allocate heap space (eg. a call to "malloc") you get private memory. Well, technically you get it as soon as you reference it -- the call to malloc just generates the mappings, the page fault when you access it instantiates the page in RAM.
3. Does Solaris 10 provide developers with methods to ask for memory that is fixed in memory and not pageable? I understand that by asking for ISM then the pages are locked in memory. But I was wondering if there are methods that an application can call that does this without having to share memory.Yes. First you must have the process privilege of "proc_lock_memory". After that you can call "mlock"

Solaris 7 compatibility question

We have to deliver statically-linked binaries to a site that is running Sparc/Solaris 7. We are running Solaris 8 but have an old workstation that is still running Solaris 2.5.1.
Two questions:
1. If we compile and statically link our binaries on Solaris 2.5.1, will they run correctly on Solaris 7?
2. If we compile and statically link our binaries on Solaris 8, will the run correctly on Solaris 7? (Seems unlikely, but it can't hurt to ask!)
Thanks

Hello,
I'm wanting to install a windows system on my iMac. My question is can I install the new Windows 7 on my iMac. If so, can I purchase a Microsoft Windows 7 Home Premium 32-bit 1-Pack for System Builders - OEM? This is what I would buy from a site such as newegg. Or, do I have to buy the full retail home version which is of course a lot more expensive.
The biggest question is can I do this with bootcamp. My current version only lists XP and Vista. Will Windows 7 work as well? I have not upgraded to the new snow leopard. Do I have to do that as well?
I sure would appreciate any info.
Thanks
That should work, i dont think theres a limit or lowest denominator for installing the latest windows on the mac

Never heard of or used WinClone? that does a good job at backing up the Windows partition...throws into a nice little image file you can save off to an external somewhere safe

General Solaris 8 patch questions

I�m relatively new to Solaris administration, although I have managed HP-UX machines. Patch management seems to be an very important task. When installed the 8_Recommended bundle across various platforms, I notice that I get a variety of different ERROR return codes ( including 8, 2, and 25). If there is a place for more basic admin questions, please let me know. Here are my questions:
1.     Are the patch clusters typically cumulative? By this I mean does the cluster resolve all dependencies required to successfully install the full bundle? If not, how would you ensure that you have all of the patches required by the cluster. This seems as if it could be a very tedious process.
2.     Is there a way to specify saved patches in some location other then /var/sadm:
3.     When installing a patch, is it required to install the patch in /var/spool/sw? I had problems when I failed to do this.
4.     Is there a way to tell the patchadd or install_cluster command to enforce all patch dependencies.?
Any other patch management tips would be useful. It seems as if Solaris makes this very difficult considering that the logging is not very good the install_cluster command does not seem to check for dependencies, it just installs all the patches and you have to figure out what patches didn�t install and why. This can be very time consuming if you have to do this for 15-20 machines.
Many Thanks

Solaris Management Console question

Just wondering. I have tried to use the Solaris Management console several times. I have a solaris 10 box setup with a fress full install and when I launch the console the window comes up:
======================================
Configuring the management Server
Starting the server for the first time may take a few minutes.
Please allow configuration to continue until you see
"Welcome to the Solaris Management Console".
======================================
It never goes past that. I have tried it on a couple of different installs and I do not think it has ever worked for me. I must be missing something simple. Can anyone point out what I am doing wrong?

running "/etc/init.d/init.wbem start" did the trick. I had suspected that a service might need to be started.
It works well on the global zone, but I am having trouble with it on my local zone. I suspect it is something I have done with that zone because I have been testing on it. I am going to spawn a new local zone and test it on that.

Solaris installation related questions/problems

I've recently purchased Sun's Solaris 8 OE media kit 2/02.
I tried installing them on two computers and experienced the following problems:
On my Pentium 3, I get the following messages when during the first steps of installation:
Determining bus types and gathering hardware configuration data...
Warning:Resource Conflict - both devices are added
NON-ACPI device: PNP0C01
Memory: 9FC00-9FFFF, FFE0000-FFF7FFF,FFF8000-FFFFFFFF,

Most surprisingly, the installation worked!!!
However, if anyone understands what the above means, its implications or other important information, I'd like to hear it and its workarounds if any.
On my newly purchased Pentium 4, I had to first remove my Ethernet card to prevent system boots during installation. My problem is that I have some hardware conflicts.
I have a "15 LCD monitor from LG.
Display adapters: ASUS vn179 DDR v28.32
GeForce 4 MX 440 64 MB BV17 Internal (MV)
I think that these two are causing the problem.
As a result, I cannot install Solaris with the windowing system.
I cannot see these types when choosing hardware devices.
Please advise on this matter.
I tried choosing some other hardware from the configuration list but the installation halted.
Am I doomed with this computer not having Solaris on it?
Last is a matter of Solaris residing on a single harddisk with other OS.
I want to have Solaris, Redhat Linux 7.3 and Windows XP Professional.
In what order should I install the OSs?
Is it recommended to make partitions before any of the above installations take place?
Which OS should go into each partition if it makes a difference?
P.S.
I'm a total newbie to Solaris and plan doing some Java programming on it.
So using a GUI is absolutely essential to me.

Hi TH,
You can install UPK server with WS 2008 R2 SP1 without any issues(may it be standard or enterprise edn.). Oracle database 11.2.0.4 can be used as well.
You can refer the installation guide for version 12.1 incase you have any queries.
You would only need to open the database port(eg 1527) or so on the subject server. There are no other specific port opening requirement on the firewall (port 80 must be open as well, but mostly it is not blocked on servers).
Let us know if you have any further queries or if you have any issues.

Solaris Express Developer Questions

Currently I am running Solaris Express Developer however i noticed there is no Subversion or CVS installed by default.
The version I am running is as follows.
bash-3.00$ uname -a
SunOS solaris-devx 5.11 snv_55b i86pc i386 i86pc
Any ideas if there is a newer version, and whether it has subversion and cvs installed by default?
Thanks

I have looked at the latest download for Solaris Express, Developer Edition 2/07 which is what I am running now.
I have connected the Sun Update Manager and I receive no updates.
Currently I am trying to use this as my development platform/workstation at work. Developing java applications seems to be well catered for however some sections of the desktop environment look a little rough.
I am having issues printing from Evince and Gimp, which seem to be using a different printing interface to other applications.
It seems that this "Developer Platform" may be a little green for use as a workstation without some proper update mechanisms...

Solaris Beginner NIC Questions...

I have been kicking around installing Solaris for a while, and i finally did it. Everything looks great and is working fine, except for my network card. I've done some research, and I am pretty sure I need to install the Tulip drivers for it, but being new to Solaris, I don't even know where to begin.
My network card is a CNet PRO200WL PCI Fast Ethernet Card with a Davicom DM9102 chipset. This was listed as compatable with the Tulip drivers, so i downloaded the Tulip drivers, popped them on a CD, and now have them on the desktop of my Solaris machine. I looked at the readme, but am still confused as to what exactly I need to do to install the driver and configure it with my network card.
Any help would be greatly appriciated. I love what I've heard about Solaris, and I am anxious to get it online to really see what it can do.
Also, on a similar note, after installation, I had the network connection lo0 set to 127.0.0.1 . I assume that lo0 is just a loopback when no network card is detected? Or is this what needs to be configured? Thanks again.

Do the Solaris dnet drivers work?
According to http://www.sun.com/bigadmin/hcl/devicelist/ they should work out of the box.
You should can check with a ifconfig dnet0 plumb.
If this works, an ifconfig -a shows your dnet0 device and all is well.
Put your hostname or IP into the +/etc/hostname.dnet0+(or create a empty file +/etc/dhcp.dnet0+ if you use DHCP) file and your Solaris should boot up with network enabled.
If the Solaris dnet driver doesn't work out of the box you could try the recommended steps described at http://www.sun.com/bigadmin/features/techtips/assign_device_to_driver.jsp
If the above steps don't help, you could try a third party driver.
You didn't say what Tulip drivers you downloaded. Are they Masayuki Murayama's from http://homepage2.nifty.com/mrym3/taiyodo/eng?
I didn't try the tu drivers, but generally his drivers work very well (Using the nfo driver myself)
The Readme explains the required steps to configure the drivers pretty well.
In general you can check if your system works with Solaris quite easily with Sun's Device Detection Tool ( http://www.sun.com/bigadmin/hcl/hcts/device_detect.html ). It should tell you if your hardware works out of the box, if there are third party drivers or if there are no drivers at all.
The lo devices is the loopback device and it is always configured, regardless if there are other NICs or network at all.

Joern

Oracle on Solaris - General UNIX Question

Anyone have a way to list out the hidden (dotfiles) only on a Solaris box? ls -a shows both hidden and normal files I just want to list the hidden files and directories.
Thanks

it's hard to list only hidden files and directories at the same time.
It's easier to use 2 commands one list hidden files like first poster did
and
ls -l | grep ^d | awk -F' ' '{print $9}'
to list all directories.

Solaris Remote Desktop Question...

Hello;
I have a quick ? for all you Solaris gods! :-)..
Is there a software package that will allow me to see a session of someone logged on!? For instance...
Windows Desktop, TeamViewer, etc., are packages that will interact with the currently logged on user & both people see the same thing, etc.
I have checked NXServer and VNC, and it doesn't seem that either of them do this, but rather use "individual" sessions so to speak!?
An I correct!? Or have I just setup the configuration files wrong!?
Thank you for the help in advance! This is important!

VNC can do this as long as both users are connected to the same session. VNC doesn't let you drop in on a session started outside of VNC.
I'm less familiar with NX, but I thought it was the same.

Solaris file descriptor question

Hi,
We have an application on Solaris 2.6 and
the shell in which the server runs has a
file descriptor limit of 1024. What does
this mean? Does this mean that every process
from the shell will have 1024 fds? What
is the maximum # of fds that a solaris 2.6
system can provide?
When I run "sysdef", I get:
ffffffff:fffffffd file descriptors
How do I interpret this line?
Is this 64K - some value?
If system limit is 64K and if each
shell has 1024, how are the fds allocated
to the shells?
What I mean is:
say I have 3 shells each with descriptor
limit of 1024, then is the distribution
something like 1024-2047 for shell 1,
2048 - 3071 for shell 2 (i.e. 3072) and
3072 - 4095 for shell 3?
Appreciate any explanation of this anyone
can offer.
thanks,
mshyam

Hi There,
About File Descriptors and Their Limitations:
All versions of Solaris (including Solaris 7 64-bit) have a default "soft" limit of 64 and a default "hard" limit of 1024.
Processes may need to open many files or sockets as file descriptors. Standard I/O (stdio) library functions have a defined limit of 256 file descriptors as the fopen() call, datatype char, will fail if it can not get a file descriptor between 0 and 255. The open() system call is of datatype int, removing this limitation. However, if open() has opened 0 to 255 file descriptors without closing any, fopen() will
not be able to open any file descriptors as all the low-numbered ones have been used up. Applications that need to use many file descriptors to open a large number of sockets, or other raw files, should be forced to use descriptors numbered above 256. This allows system functions such as name services, to work as they depend upon stdio routines.
(See p 368 "Performance and Tuning - Java and the Internet").
There are limitations on the number of file descriptors
available to the current shell and its descendents. (See the ulimit man page). The maximum number of file descriptors that can be safely used for the shell and Solaris processes is 1024.
This limitation has been lifted for Solaris 7 64-bit which can be 64k (65536).
Therefore the recommended maximum values to be added to /etc/system are:
set rlim_fd_cur=1024
set rlim_fd_max=1024
To use the limit command with csh:
% limit descriptors 1024
To use the ulimit command with Bourne or ksh:
$ ulimit -n 1024
However, some third-party applications need the max raised. A possible recommendation would be to increase rlim_fd_max, but not the default (rlim_fd_cur). Then rlim_fd_cur can be raised on a per-process basis if needed, but the higher setting
for rlim_fd_max doesn't affect all processes.
I hope this helps your understanding about systemwide file descriptor max limit in conjunction with shell and per process file descriptor limits.
