Compare Linux with Solaris

We have tested the I/O performance on Intel-Solaris 7.0 and Intel-RedHat Linux.
We found that Intel-Linux has much better performance than Intel-Solaris.
Now, we are thinking to install Oracle 8i on Intel-Linux.
However, before we make this decision, we would like to hear more opinions about
the advantages and disadvantages of running Oracle on these two different
operating systems. We'll appreciate, if you can give me your opinions.
Thanks

This from experience of running large-db ecommerce site on intel linux with redhat 6.1, oracle 805 and 8i, with some java functions, intermedia, time-series module, 4 different servers on aolserver 2.33 and aolserver 3.0 on 1 machine: it's stable.
I never had a crash, and no locking or restarting due to either aolserver or oracle.
With a few minor modifications in linux to support some enterprise functions (raw devices, async io) linux on intel with oracle is almost ready to kick sun's ass. (at least on the 1 to 8 cpu server market)

This is actually supposed to be a Java forum, so you are way off topic. And you would be better off to consider what software you are going to use first, and then decide what hardware you are going to run it on.

[SOLVED] SGA_MAX_SIZE pre-allocated with Solaris 10?

Hi all,
I'm about to build a new production database to migrate an existing 8.1.7 database to 10.2.0.3. I'm in the enviable position of having a good chunk of memory to play with on the new system (compared with the existing one) so was looking at a suitable size for the SGA... when something pinged in my memory about SGA_MAX_SIZE and memory allocation in the OS where some platforms will allocate the entire amount of SGA_MAX_SIZE rather than just SGA_TARGET.
So I did a little test. Using Solaris 10 and Oracle 10.2.0.3 I've created a basic database with SGA_MAX_SIZE set to 400MB and SGA_TARGET 280MB

$ I wasn't sure whether Solaris 10 was one of the OSs with truly dynamic memory for the SGA but had hoped it was... this seems to say different. Really I'm just after some confirmation that I'm reading this correctly.
Thanks.

I don't want to get bogged down in too many details, as the links provided in previous posts have many details of SGA tests and the results of what happened. I just want to add a bit of explanation about the Oracle SGA and shared memory on UNIX and Solaris in particular.
As you know Oracle's SGA is generally a single segment of shared memory. Historically this was 'normal' memory and could be paged out to the swap device. So a 500 MB SGA on a 1 GB physical memory system, would allocate 500 MB from the swap device for paging purposes, but might not use 500 MB of physical memory i.e. free memory might not decrease by 500 MB. How much physical memory depended on what pages in the SGA were accessed, and how frequently.
At some point some people realised that this paging of the SGA was actually slowing performance of Oracle, as now some 'memory' accesses by Oracle could actually cause 'disk' accesses by paging in saved pages from the swap device. So some operating systems introduced a 'lock' option when creating a shared memory segment (shmat system call if memory serves me). And this was often enabled by a corresponding Oracle initialisation parameter, such as lock_sga.
Now a 'locked' SGA did use up the full physical memory, and was guaranteed not to be paged out to disk. So Oracle SGA access was now always at memory speed, and consistent.
Some operating systems took advantage of this 'lock' flag to shared memory segment creation to implement some other performance optimisations. One is not to allocate paging storage from swap space anyway, as it cannot be used by this shared memory segment. Another is to share the secondary page tables within the virtual memory sub-system for this segment over all processes attached to it i.e. one shared page table for the segment, not one page table per process. This can lead to massive memory savings on large SGAs with many attached shadow server processes. Another optimisation on this non-paged, contiguous memory segment is to use large memory pages instead of standard small ones. On Solaris instead of one page entry covering 8 KB of physical memory, it covers 8 MB of physical memory. This reduces the size of the virtual memory page table by a factor of 1,000 - another major memory saving.
These were some of the optimisations that the original Red Hat Enterprise Linux had to introduce, to play catch up with Solaris, and to not waste memory on large page tables.
Due to these extra optimisations, Solaris chose to call this 'locking' of shared memory segments 'initimate shared memory' or ISM for short. And I think there was a corresponding Oracle parameter 'use_ism'. This is now the default setting in Oracle ports to Solaris.
As a result, this is why when Oracle grabs its shared memory segment up front (SGA_MAX_SIZE), it results in that amount of real physical memory being allocated and used.
With Oracle 9i and 10g when Oracle introduced the SGA_TARGET and other settings and could dynamically resize the SGA, this messed things up for Solaris. Because the shared memory segment was 'Intimate' by default, and was not backed up by paging space on the swap device, it could never shrink in size, or release memory as it could not be paged out.
Eventually Sun wrote a work around for this problem, and called it Dynamic Intimate Shared Memory (DISM). This is not on by default in Oracle, hence you are seeing all your shared memory segments using the same amount of physical memory. DISM allows the 'lock' flag to be turned on and off on a shared memory segment, and to be done over various memory sizes.
I am not sure of the details, and so am beginning to get vague here. But I remember that this was a workaround on Sun's part to still get the benefits of ISM and the memory savings from large virtual memory pages and shared secondary page tables, while allowing Oracle to manage the SGA size dynamically and be able to release memory back for use by other things. I'm not sure if DISM allows Oracle to mark memory areas as pageable or locked, or whether it allows Oracle to really grow and shrink the size of a single shared memory segment. I presumed it added yet more flags to the various shared memory system calls.
Although DISM should work on normal, single Solaris systems, as you know it is not enabled by default, and requires a special initialisation parameter. Also be aware that there are issues with DISM on high end Solaris systems that support Domains (F15K, F25K, etc.) and in Solaris Zones or Containers. Domains have problems when you want to dynamically remove a CPU/Memory board from the system, and the allocations of memory on that board must be reallocated to other memory boards. This can break the rule that a locked shared memory segment must occupy contiguous physical memory. It took Sun another couple of releases of Solaris (or patches or quarterly releases) before they got DISM to work properly in a system with domains.
I hope I am not trying to teach my granny to suck eggs, if you know what I mean. I just thought I'd provide a bit more background details.

Performance (Linux or Solaris)

Hi folks,
We have been asked by many clients which performs better / faster (Linux vs Solaris).
The environment is:
Intel Xeon Server Hardware
Local Disk (SAS) - RAID 5
Single Server install
Single Location
VirtualBox as Hypervisor
I am asking for your feedback / experience with Linux vs Solaris implementing VDI 3.4.1

Hi,
we have done some extensive testing on this. One of our clients had some severe issues with performance on Linux after a migration from solaris to linux (on the same hardware) the system load/utilization went up by a factor of 4-5 (server could easily handle 200 sessions with solaris and only 40-50 with linux). We never managed to find the root cause (or a solution) for this and migrated back to solaris.
But we tried to replicate this issue in the lab (without success). So what we did was this:
Install Solaris 10 and Linux on one hard drive each and also install SRS 5.3.1 (we also tried this with a few older versions). We set up kiosk sessions to connect to a windows terminal server (we did not bother to compare virtualbox perfoamce) and launch a web browser to a website with loads of flash and moving content. We had about 20 DTUs connect to this server and monitored the system load, utilization and so on of the Xnewt processes. At one point we also automatically started some audio stream to measure the performance of utaudiod. The result (for 2 different servers) was that linux and solaris are really close to each other in performance terms. Solaris showed a little less utilization, about 5-10% maybe. But really quite negligable.
Long story short: we have seen really poor performance with linux once but in all other cases linux performed almost as well as solaris. And we never compared the virtualbox hypervisors which might be yet another story.

Help with Solaris.....any help would be nice

I have to write a paper comparing and contrasting Solaris with DOS/MSDOS.....you wouldnt think this would be hard but it is......is ththere a place where I can find a head to head comparsion? If not perhaps some of you familiar with Solaris could give me some points to start with......I should point out I have never used or seen Solaris I am completely new to this area and it may seem simple but the truth is Im a little overwhelmed by all the information....cant see the forrest for the trees...........so any help would be nice ....thanks in advance

Hi,
Solaris is so much more advanced an OS than DOS that a comparison is not straightforward, but here are some less than exhaustive suggestions. Please bear in mind I m not a DOS person, and these are just my personal thoughts on the subject; apologies to Microsoft afficionados for any mistakes.
Similarities:
Both DOS and Solaris are Operating Systems. They provide access to machine resources, like a printer port, or a disk ( through the filesystem), by providing an Application Programming Interface, thus saving programmers from learning the underlying details and machine language of each machine they use. So for example in DOS compiler routines make use of INT 21h to access system services.In solaris we use the system call interface (which does a similar thing underneath).
They also both provide a command shell for ordinary users. In DOS we have command.com, in Solaris you may use Korn shells for example.
Differences
DOS is a single user operating system. Solaris is multiuser, multitasking and multiprocessing.
That is to say Solaris supports multiple programs running on the system at the same time. It will context switch between them to give the illusion of concurrency on a uniprocessor system (time-slicing). On a multiprocessor some tasks will run concurrently.
Many users can log on to a Solaris system (via a serial terminals, or a network connection (telnet or X windows)) and run programs at the same time. Full networking facilities are built in.
Dos only provides the ability to fileshare across the network, using the add on Lan Manager.
Because multiple users run processes (threads/tasks ...) concurrently, Solaris provides extensive security, which DOS doesnt. Each process is owned by a user and runs in its own virtual memory space and is prevented from interfering with any other process memory or other users processes. The operating system and its data is held in protected kernel memory and not directly accessible to processes, so malfunctioning user program cant crash the system accidentally or maliciously.
Devices and files are protected through filesystem permissions, so a device or file has an owner, a group owner and various permissions attributes such as read/write/execute.
Solaris also implements filesystem Access Control Lists (ACLs).
Solaris runs in 32bit protected mode on x86 processors, giving it access to the full address range of the processor (4GB using 4k pages). DOS uses the 16bit segmented memory model.
On ultrasparc systems or the forthcoming Intel Itanium systems, Solaris runs in 64bit mode, giving it access to vastly more memory and
faster computation. (note also DOS only runs on x86 processors).
Who are you writing the paper for? It would probably help some of the readers here with posting suggestions. Some specific questions would be good too.
However, you should try to get access to a solaris system on a network and maybe have a friendly sysadmin show you around a bit.
Do you know anyone with a LINUX system? Solaris and LINUX are variants of the UNIX OS and for your purposes a comparison of LINUX and DOS may suffice.
Hope that is some help.

Adding the /etc/host.deny file like linux in solaris 10.

Dears,
I need to add a file which will works like the file of /etc/hosts.deny of Linux in Solaris.
If it is possible in the same manner please let me know that, and if it need some other trick to deny a specific host to access the system please tell me the way to do that.
Eagerly waiting to hear from you.
BR//
Sohel.

IPfilter can deny a specific IP address access to the host - enable IPFilter with svcadm and edit the /etc/ipf/ipf.conf file to add the IP to block. An example could be:
block in log quick on bnx0 proto tcp from 192.168.1.5/32 to any
I use IPfilter to pass and block all sorts of specific IP addresses as well as block/allow specific ports (like only specific hosts can use port 22, ssh).

Help with Solaris 10

Hello,
I just got ahold of a SunBlade 100 system (that's having video problems, I already posted what the problem is in the Hardware section) and I would like some help with Solaris 10. I have never used Sun before, and I figured why not get a machine and start learning. =)
Anyways, I do alot of web design and networking...on Mac's though.
I'm setting this system up on a Rack along with a Win Xp box, a Mac G4, and a Linux Mint machine.
I also have two of these Scsi towers that came with the Sun System. They can each hold I believe 8-10 Drives each? Not sure..that i want to setup at a later time.
My questin is this. I'd like to run websites off my Sun system. But i'm not sure how to transfer my files from iWeb to the Sun, and how to control the sites on the system, as well as turning the site on, off, etc.
I'd also like to store music on it as well. Because I can have alot of Scsi drives, i figured I can get quite large amount of storage for songs. I'd like to set it up to where I can give someone a login information and a website (ex. myuploadsite.net) and they can go in, and upload there music. But, I'd like to make it to where I can make the website in iWeb, and run it off the Sun system, and store all the files on the Sun as well.
And my last question is this. How do I remote desktop to a Sun System from a Mac. I'm using Apple Remote Desktop, and the way the rack is setup, is that I remote connect to the Xp, linux, and Mac box's (saves monitors, and space. =), and also because I'm usually never home...
Thanks in advance for the help!
Oh, and if anyone has a Instant Messanger and wouldn't mind having a chat with me, that would be great.

hi all
1st of all, thank u for support...
then i need some explaination for the installation of 119090-25 (iscsi driver + target) installation
this patch requrires kernel patch (118833-36-1) that requires 3 other patches 118918-13, 119042-09 and 119578-30
now i have some questions for kernel installation patch... on my server is running oracle and i ask if this upgrade should give some problem with services running.
could u guide me through this adventure? I repeat i'm totally newbie and i'm reading as much as possible to understand as best i can solaris 10
thank u
sorry for my english

Compatible Laptops with Solaris 10?

Hi,
I want to buy a laptop that will be compatible with Solaris 10, but since it's still beta, they don't have any test suite certified systems on the list yet.
Can anyone suggest a cheaper laptop that is compatible with 10? I assume any laptop that works with 9 will also work under 10.
I'd like to get one with minimal configuration...I don't really want to have to edit text files and install xfree to get things working. It will be a dual-boot system with windows, and I anticipate having to re-install Solaris here and there since Windows is territorial when that needs to be re-installed...
If anyone has any suggestions, please reply.
Thanks in advance.

A good starting point is Linux. If the laptop runs Linux very well out of the box, and you use stable distro such as JDS (this is based on Linux 2.4.19), then you have a better chance.
Another point is Xfree86, since Solaris 10 now bundles it.
I'm using Dell 8500 with nvidia. Don't use it, since you don't want to search for drivers. I had to manually get the ethernet working.
hope it helps

Compilation aborted, too many Error messages.
I have checked on __builtin_expect and it I cannot find it in with the system's include files. I have also looked at the web and from what I read I understand the for solaris this is not strictly necessary.
The package was developed at Universitaet Trier, and there is an email I have used, but just in case, I would be grateful to see how I could - without knowing the full code get it to compile and useable.

You can try the following macro definition to convert uses of __builtin_expect to standard code (but without branch-prediction information):
#define __builtin_expect(e, n) ((e)==(n))I think the correct definition would be:
#define __builtin_expect(e,n) (e)

Sharing windows hp printer with solaris

hi
I have hp laser jet P1102 printer which i want to share with solaris. I have added the printer in solaris using lpadmin but i am not able to print to this printer.
I have another printer which is laserjet 1320 which is added to solaris box in the same way and i am able to print without any issues.
i would like to know if there is any step to know if a printer would print successfully from unix.
looking forward to your support.

thank you very much for your reply
so when i buy a new printer i how do i know it will be able to print from solaris. By comparing the above two printers i can see that one printer is Postscript enabled which is actually printing from solaris. So if i buy a printer that supports posscript will it print properly?
please correct me if my understanding is wrong becuase we need to buy a printer which will print from solaris.

Hi MuraliDharan V,
It would had been better if you had searched first;
Here is one
Advantage for Linux64-bit Versus Solaris-x86_64 OS in RAC
And beside that your question is incomplete:
-What Oracle? Database, etc
-Which Version? 9i, 10g, etc
Aside from that a simple search on google might have answered your question as well.
But I think there is some new trend of dumping questions here before searching.
