Numbers of Oracle DB usage on different operating systems

Hi all,
I am looking for numbers that breakdown in what proportion Oracle DB is used in different operating systems, specifically the percentage of use in each group of operating systems.
- Windows
- OpenVMS
- Linux
- Unixes.
- Others
Could someone provide some numbers or a link to where I could get the information?
I am especially interested in windows and OpenVMS...
Best wishes to all
Andre

Hi Andy,
I'm seeing lot of companies prefer Unix(Solaris, HP, Linux) as a production. My experience working with 3 big clients like Cingular (USA), Orange (UK) & SKY(UK) they have many solaris oracle and few HP oracle (Orange).
Cheers,

Jvm 1.4,1.5 default memory usage in Ram in different operating systems

Hi ,
Can anyone help me with the default memory occupied by Jvm in different operating systems ?
I have practically seen that jdk1.4,jdk1.5,jdk1.3 has around 64 Mb as the
default size on 32 bit machines .
I am in need of the similar data for jvms on Solaris,Unix and Linux machines . Also much curious to know about the default memory occupied on 64 bit machines. It would be really great if the statistical data is present in any link .
Thanks and Regards
Suman

Default Heap sizes on 64 bit JVM are by default 30% bigger then the 32bit version to accomodate the extra memory used by 64 bit object pointers instead of 32 bit.
This link plus documents close to it answers most questions.

DB Restoration in different Operating system

Dear Experts,
In SAP supporting Database, which DB will allow the database backup that can be restored in different Operating System Platform.
Say for example: I will take a database backup on windows system and i want to restore the same in different OS other than windows.
BR,
Jai

Generally: Not supported.
Each operating system stores the data in different block sizes plus it may have different endianesses.
For Oracle there are various options:
- OOO (see Note 1508271 - Oracle to Oracle Online Migration - Triple-O)
- transportable tablepsaces (Note 1367451 - Oracle 10g: Transportable Database)
- standard R3load procedure (hetergoeneous sytem copy)
For all those migrations you need to have a certified migration consultant on-site (see http//service.sap.com/osdbmigration).

Java Program in Different Operation Systems

Just one question? can I use a java program (.jar) compiled in windows, in my solaris only by copying the .jar , or do I need to compile it with the solaris SDK?
Thanks in advance for your help and sorry for my ignorance.
Javier

Hi,
It is not required to recompile bcoz the .jar file contains .class files which are independent of Operating system which will be taken care (interpreted) by JVM.
Actually there is different JVM's for different operating systems(Windows 98,Unix,OS/2). No need to have differend java class file for different operating system. Pls, remember Java is platform independent language.

HELP!! Authorization in the same laptop with different operation systems

My BF installed Win 7 operation system on his laptop yesterday and re-authorized it when he used iTunes. However, when he finished authorization, a dialog block showing that "*Including this one, you have authorised two computers out of your available 5*" appeared; what's worse, when he connected his iPhone to the laptop, it deleted all the bought apps in the iPhone, instead of synchronizating.
I also want to install Win 7 operation system, but I'm afraid that the same thing would happen again (to my iTouch).
We're quite confused that why the authorization in the same laptop with different operation systems is counted as two times. Friends who know please tell us whether this is the case.. If not, please tell us how to deal with it as we frequently re-install operation system for quicker operation.

It's the *operating system* that is authorised, not the particular user profile or the hardware. Before upgrading/reinstalling deauthorise and you won't run out...

Memory Allocation under Different Operating Systems

Hello
What is the exact behavior of java -Xmsn -Xmxn under different operating systems?
I am running my application on windows and linux.
In linux i specify java -Xms512M -Xmx512M and it seems to only initially allocate 22M (i have enough space on the machine).
I also do the same on windows and it seems to allocate 97M or so.
Does any understand what exactly happens when you allocate min and max memory on different operating systems? Are these options fully functioning?
Thanks

AS far as I know -Xms is the minimum size of the heap, and when the VM will be created it'll bild a heap of this size.
Ussually on servers this parameters are fixed to the same size, to the limit of memory that the machine has. This has one advantage: everytime the heap increases your application may be stopped because of the need of ollocate new memory. If you make the initial size of the heap to bhe equal to the minimum this never will occur, despite the starupo of the application will be slower due to the need of allocating big amounts of Ram.
About what you have seen, I'm afraid you are doing something wrong. This parameter works, and if you stated that -Xms128m, the initial heap of your aplication will be this (I've just checked it under Windows 2000).

Multicasting using different operating systems

Hi,
I was testing the multicast example from the Java Tutorial (http://java.sun.com/docs/books/tutorial/networking/datagrams/broadcasting.html). The example does not seem to work with machines running different operating systems. I tried running the example server on Solaris machines and the client on Linux machines, and vice versa. The only machines that receive data are the machines running the same OS. The machines are on the same subnet and are all using Java v1.3.1.
Any ideas on how to get this working?
Thanks,
Andrew

Did more testing. Seems to work between Linux and Windows (NT/2000). But not between Solaris and anything.

Using different operating systems?

Can compiled code be moved to a machine with a different operating system and still run ok?

Yes. You should beasble to write a prog in Windows and Run it on a Mac. When you compile it only compile some of the code. Once the program is run the rest of the code compiles. Each OS has its own Java Virtual Machine or Java Runtime Environment

Exchange Datasfrom different operating systems

Guys ?
Without any jailbreaking do iPhones can exchange datas from different operating systems like Android ?

Sorry no not for music.
Music needs to be in your itunes library and then sync your phone to it.

Just wondering if I can have a different operating system......

Just wondering if I can have a different operating system on an external drive....
You know have Tiger in the main, and Leopard on an external. I always thought that the you can only do that with the 2 internal drives....
Thx....

I believe you can do that, but for an external drive to be bootable, I think it has to be either FW or eSATA.

Extra licence for different operating system?

I have Lightroom 5.7 on my home PC, running Windows 7. I plan to get a small laptop computer for travel, possibly a Macbook Air. Would I need to pay for another license for the different operating system?

IPop Use with different operating systems Windows And Mac Osx

so the quetion is this can i use my IPod with different Operatin systems?
I have a MacBook at home where i keep all my Music in and at the office i have a Windows network i would like to carry some music from home to the office using my IPod. I thought that a solution is to Partition my Ipod 40G in 2 parts and have one of them FAT so that my Windows operating system can view it.
Did any of you done it? and if so How? did you loose the use of some of the IPod functions?
let me Know if there are ways to carry music using your Ipod from the MacOSX to Windows Prof or home edition thanks!
Donatello

Your problem has nothing to do with data vs music. Music IS data. I've used my iPod for data and music since the first iPod was released. There's no reason to think the two OS versions are involved either.
Look at your usage practices - and I'm not necessarily suggesting you are abusing your computer. Has one of your computers crashed while the iPod was connected? This could cause data damage that might explain the problem. Have you ever disconnected the iPod without un-mounting it first?
You might also be creating fragmentation problems if you frequently add and remove data files while at the same time adding and removing music. One decision I made when I was using my iPod to transport lots of movies and photos for a project was to NOT make any music changes during that busy two week period.

Client copy between different operating systems.

Hi Experts,
Our production system is running on HP-UX OS. We are installing a standby quality system and planning to do a client copy to this system from production by taking this into transport domain. But this new system is in windows. So, is it possible to perform a client copy where the source system is HP -UX and target system is windows??
Regards,
Amit.

Hi Amit,
Follow SAP Note 552711 for client copy. Refer to qns no 4 & 5, which is relevant for your question.
Can I create client copies in a heterogeneous system landscape?
Remote copies or client transports can also be carried out between different database and operating systems.

Drivers for different Operating Systems in one Task Sequence

Hi,
I would like to implement a solution for our deployment process. We are using UDI Wizard, and in this moment in time we are deploying only Windows 7 x64 and Windows 8.1 x64.
Here is how it looks in UDI:
Drivers for our HP laptops are setup and working with Windows 7 x64, but when I choose Windows 8.1 x64 from my dropdown menu in UDI, during the deployment process I get the driver package that is made for Windows 7 x64 version.
What am I missing here? Ofcourse i added all of this conditions to see if it works because I am testing it right now:
If possible we would like to use the same TS for both OS (and in the future Windows 10).
Thanks,

Hi Jason,
thanks for your reply. As I tried to explain above, I just added many conditions to see if it would work, random throwing of everything, nothing more. Well it didnt.
It worked like this:
1. First you configure the operating systems in UDI wizard, then their name is what counts.
2. Then you implement OS into UDI task sequence, and for that to works you also use OSDImageName variable.
For example Windows 7 x64 Enterprise you Add condition->TS variable->OSDImageName equals "Windows 7 x64 Enterprise", I got that name from UDI wizard. For Windows 8 x64 the same, just make another step including Install Operating system Windows
8 and change the variable according to the name.
3. Then create install driver steps both for different OS and also add the condition like bellow:
You have to specify both conditions in order to work, otherwise it will install both driver packages.
Thanks,

Oracle's block size and operative system cluster

hallo,
I would like to move our oracle's database 10.2g from server in a datacenter with Vmware environment, where the net admin will install windows 2008 with 64 bit.
Now, the net admin strong believe that if oracle's block size is near at size of cluster of the cooked filesystem, oracle perfomance will increase, and he wants to set oracle's block size to 64 K
It's a right idea or a mistake?
thanks' in advance anyone answers.

I think he's probably had more experience with SQL Server - which is more closely integrated with the operating system, which means this type of thinking can be of some help. SQL Server has a fixed extent size of 64K (8 x 8KB pages) and an algorithm that allows it to use readahead on extents, so it's fairly common practice to synchronise the SQL Server extents with the operating system allocation unit - which is why, historically, SQL Server admins would set up the O/S with a 64KB allocation unit and fuss about aligning the allocation unit properly on the hardware.
This type of thinking is not quite so important in Oracle systems.
