Significant difference in temperature windows vs linux

Lately I monitored CPU and motherboard heat levels in both windows and linux.
I installed TPFancontrol in windows and Ksensors in ubuntu.
The results were more than eloquent :
the average temperature was 50 - 55 celcius in windows and 30 - 35 celcius in ubuntu!
this translates to 1800 rpm in windows and 0 zero or 1800 rpm max in linux !
If you want your laptop to run cooler and thus achieve longer life go with linux !
However, I cannot determine what causes this 20-degree difference...
note
I have the T500 with T9400 CPU and use the Intel GPU.

windows uses more hardware resource.try to change the settings for performance.
system properties > advanced > performance > settings > adjust for best performance

Difference in read/write between Windows Vs Linux

Hi,
Can you please write, whether it is a bug or my ignorance. I thought, if a java program runs in Windows then it will run in other platform too, without editing any code. It proved me wrong. So is it a bug?
Ref: Fedora linux version 5
Kernel ver. 2.6.17
jdk version - build 1.5.0_06-b05
I was working on a web service. The server side program connects to an application using socket program and sends back data to client.
While it was working very fine with Windows XP. When I moved the service to Linux (above said linux). The program stopped working. When I explored it, I found 3 things.
1. I was using PrintWriter
PrintWriter outputStream = new PrintWriter(new OutputStreamWriter(socket.getOutputStream()), true);
to write into the socket. It works fine in Windows but not in Linux. ie. it sends different bytes in linux. Thus fails. When I changed it to BufferedOutputStream it works fine.
BufferedOutputStream outputStream = new BufferedOutputStream (socket.getOutputStream());
2. I was using BufferedReader to read
BufferedReader inputStream = new BufferedReader(new InputStreamReader(socket.getInputStream()));
data from socket. It reads. But byte varies from expectation. The same program works very well with windows.
I used DataInputStream now. that works. but..
DataInputStream inputStream = new DataInputStream(socket.getInputStream());
3. While reading it was suppossed to read 2098 bytes, instead it reads 1448 bytes. It reads correctly in Windows, but not in the above said linux.
Is it a bug or there is a difference in reading and writing from socket between Windows and Linux ( even though it is same JVM).
Thanks
Sasi.

Thanks a lot for both of you.
I believe, \r\n Vs \n could not be the reason.
Because, I was sending binary data.Then you should not be using Writer at all!
>
With regard to "utf-8", I thought of that but I did
not try to issue it in the function. Because, I was
trying to send and receive raw binary data.Then you should not be using Writer at all!
>
Now, You may ask that why did you use PrintWriter.
Because, the data had unsigned byte values. Makes no difference - you should not be using Writer at all!
So I
converted everything in to char array and send it.Will cause you problems at some point on some platform unless you use Base64 or HEX encoding.
especially, whereever unsigned byte was required, I
used (byte & Oxff). It worked very well with
Windows. So I just go ahead doing other things.I use byte & 0xff for dealing with unsigned valued but your use sounds dangerous.
>
Here my question is, I assumed that if a program is
written in java and complied on jvm x, then
irrespective of the underlying OS, if the jvm is the
same x, then the program should run without error. Is
it wrong. If it is not wrong, then is it a jre bug?Your program will work if you have not used any implicit or explicit platform dependencies. For example, if in your program then you have hard codes a path as "C:\Program Files" then it will work on Windows (but then only if it has a C drive) but not on Unix.
Any program has to deal with a number of platform specific features and Java protects you from them as much as possible BUT you must deal with things like Locale, EOL and default character encoding.
No! Of course it is not a jre bug. You have coded to a specific platform and are then are suprised when it fails on other platforms.

Differences on Windows and Linux JVM about java.util.zip package

Hello, there!
I need some help if someone else has already face this problem.
I have a Java server that process the bytes of a SWF File stored in the server and ouptut it to the user through a Servlet. The file was decompressed and re-compressed using the java.util.zip package (Deflater/Inflater).
Everything works fine on Windows Server 2008 server. But now we need to migrate the server to Linux. The problem is that when I test the website now, the file seens to be corrupted.
What really intrigues me is that everything runs normal on Windows Server configuration, when changed to Linux, the final file seens to be corrupeted... what could possible be the cause? Is there any difference between java.util.zip package on Window and Linux JVM?
My Windows Server is:
. Windows Server 2008 (6.0 - x86)
. Apache 2.2.11
. Tomcat 6.0.16.0
. Java JDK 1.6.0_12-b04
My CentOS Server is
. CentOS 5.4 (2.6.18-164.15.1.el5 - i386)
. Apache 2.2.3
. Tomcat 6.0.16.0
. Java JDK 1.6.0_12-b04
Please, if someone could give me a lead, I would appreciate very much!
Thank you all in advance,
CaioToOn!

Thank you for the answer, but no. The path is correct.That's not what he meant. Zip file/directory entries are supposed to use / as the path separator. It is possible to use \ but such Zip files will only work under Windows. You may have erred here.Ohhh, I had really missunderstood what Ray said. But, I still think that this is not the problem, since the ZIP is a single SWF file generated by Flex SDK 3.4 and compressed in the ZLIB open standard (as in page 13, at [http://www.adobe.com/devnet/swf/pdf/swf_file_format_spec_v9.pdf|http://www.adobe.com/devnet/swf/pdf/swf_file_format_spec_v9.pdf] ). This is how Flash Compiler compress the files.
jschell wrote:
If the above suggestions do not solve the problem...Specify in detail with the exact steps used how you determined that it was corrupted.The reason why I believe the SWF is getting corrupted is that when it is loaded by Flash Player (in the client-side) the Player throws a VerifyError: Error # 1033. The [documentation says (see error 1033)|http://help.adobe.com/en_US/AS3LCR/Flash_10.0/runtimeErrors.html] that this error means that the SWF file is corrupted.
As I said, what intrigues me is that this work perfectly in a Windows Server 2008 server. I just had setup a CentOS server and deployed the application. The client-remains unchanged, so why could the result change?
raychen wrote:
I would remove the side effect you are doing and send the file straight through, with decompress and compress, the servlet. It is more likely that you have a bug in your swf processor than the zip library.
I had already tried it when first coding, in Windows Server 2008, it had not worked.
Thank you all for the help.

Transaction behavior changed with change in Windows to Linux Environment

Hi All,
I am facing a very weird problem.
I have a 2 BPEL Synchronous Services lets say A & B. A calls B in its flow and B inserts a row into database and then retrieves the inserted row (as the primary key is sequence generated through a Trigger).
This flow was working perfectly when:
·     It was on windows Development Box with SOA SUITE and DB Server on the same machine.
·     All the DB adapters had jca:Address information in it.
Problem:
·     After moving them to a Unix box with a remote DB Server, I am seeing the problem that retrieval is happening before commit of insert and failing.
Point to remember:
·     Insertion, selection, assignment all are happening in the different ‘SCOPE’
·     I have tried even putting them in a single scope but error remained same.
·     I have even tried putting a wait between them, so it’s a plain “Transaction not commited “issue
I am expecting it could be an issue with the way Data source has been created or something else.
Please suggest your pointers on this.
Thank you.

Hi Win
1. There is absolutely NO changes or specific requirements to deploy a portal EAR created from Windows and deploying on Unix or Linux Env. We do this very often. I export my entire portal applicatoin (EAR, WAR and dataSync if its there) from Workshop or Eclipse (10.3.2) IDE as .EAR file. Then we can deploy this .EAR file pretty much in any Portal Domain on any Env like Linux. So first I want to clarify that there is NO need to change any files or do steps to deploy a portal EAR from Windows to Linux Env.
2. Now coming to your error, the root cause seems to be this: java.lang.ClassNotFoundException: org.apache.beehive.netui.pageflow.PageFlowContextListener
a) On Windows did you test your EAR on a Portal Domain. I assume you may have already did this.
b) Is the domain that you created on the Linux Env and its version matches exactly with what you had in Windows Env. Say in Windows if you have WLP 10.3.1, then on Linux also you should have WLP 10.3.1. If not, you need to upgrade your portal EAR first in Windows to 10.3.x and then deploy.
c) Compare the config.xml file modules specially the portal framework shared modules. They should be same in both Windows and Unix except for the location ofcourse.
d) On Windows, by any chance did you deploy any extra additional modules in the portaldomain. If so do the same on Linux Env also.
e) Other then config.xml file, all the other details are within the .EAR file itself like weblogic.xml, weblogic-application.xml file etc etc.
f) So better compare you config.xml file in both the working and not working Envs.
g) Also on Linux, are you deploying on Single Server domain or cluster domain. If cluster, make sure you deploy your portalEar only to Cluster because none of hte shared modules are deployed to Admin. So deploy only to cluster.
Thanks

Copy of a CD (created by Disk Utility) not recognized by Windows or Linux

I created a copy of AutoCAD 2005 (not pirating it... just wanted a backup copy of the install CD).
I used Disk Utility (File > New > Disk Image From Folder) to successfully create a DMG file on my MacBook. I could mount the DMG and browse all the files on it.
I then burned a CD (Disk Utility > select DMG > click burn), which mounts fine on OSX. However, my Windows and Linux boxes will not recognize it (while they recognize the original CD just fine).
I tried again, this time setting the file format to DVD/CD master. It made a CDR file, which I burned to CD. Got the same result: Windows and Linux don't recognize it while OSX does.
So instead I burned the files to a CD ala drag and drop using Finder. This time the CD was recognized by Windows and I used it to install AutoCAD.
However, my understanding is that doing it this way won't work for a bootable CD, so I'd like to figure out why Disk Utility wasn't able to make an exact copy.
Any thoughts? Problem with copy protection? Problem with the CD's file system?
Details about the optical drive in my MacBook (1st gen 2.0GHz, 2GB RAM):
MATSHITA DVD-R UJ-857:
Firmware Revision: HBE4
Interconnect: ATAPI
Burn Support: Yes (Apple Shipped/Supported)
Cache: 2048 KB
Reads DVD: Yes
CD-Write: -R, -RW
DVD-Write: -R, -RW, +R, +RW
Burn Underrun Protection CD: Yes
Burn Underrun Protection DVD: Yes
Write Strategies: CD-TAO, CD-SAO, DVD-DAO
Media: No
MacBook 1st gen CoreDuo 2.0GHz, 2GB RAM Mac OS X (10.4.8)

Yeah OS X's Disk Utility doesn't burn using the ISO 9660 file system while Finder does (I could swear I made a copy of an MS Office CD with Disk Utility, but maybe I'm remembering wrong). Anyway, Disco (a program I got in a MacHeist bundle) will make an exact copy of CDs. Anyone looking for a free solution, check out LiquidCD and burn, which may have the ability to copy Windows CDs (appears to be on their lists of features, but I haven't tried them myself).

Sync iPod to Mac, but store files on Windows and Linux

I am an advanced user on both mac and widows system. I had my old 3rd Gen ipod where it was in FAT32 format and would sync to a Win machine. Then I could use the ipod to transfer data (ala external harddrive) on windows and mac platforms.
So now I have a 5th Gen Ipod and Itunes on my G5. Today I wanted to use the ipod to move some files between my work windows machine and home to my mac. To make a long story short the new ipod is formatted to be hfs+ journeled system, which windows can't read.
So I figure the easy solution is to reformat the ipod to be win-dos format, let it put the ipod software on, dump the library back and I should have a 5th gen with FAT32 that can be read by windows (or linux). So here's the rub
I used Disk Utility in OSX to partition the ipod several times. the first time I just specified ms-dos format (or whatever the disk utility calls a windows partition). All went well until the updater could not put the software on the new ipod claiming that it had to be in mac format. Then I tried to split the drive and parition into a large mac/hfs partition (for all the itunes files) and a small windows partition for the ipod (for data file storage). The problem is that the updater kept selecting the fat32 partition for installation (because I had to choose master boot record in order to be able to put the windows parition on there. at least this is what I suspect was happening). Two partitions woudl mount on the desktop, but only one would control the ipod.
So why not just let the windows parition be the one partition that had the ipod control software on it, you say? Because then I'm back to the problem that the iPod Updater won't deal with updating the windows partition.
Any ideas on a work around?

My concern is that when I have to update the iPod (in the future), will the windows based updater software be required?
Only if you want to continue to use it on Windows machines.
If you want to use the Mac Upddater, it will not be read by Windows.
If I do what you are suggesting, will the ipod return to being a resident mac based sycing device even though the first update/install of the ipod software was on a windows machine?
No. You can use it on both/either Mac and WIndows.
This is why I thougth some sort of partition with space set aside for the windows partition would be the workaround?
The iPod Updater formats the entire disk, not a partition.

Does anyone know what is the major differences between the windows 8.1 option listed

Hello, I have two questions. I downloaded
Windows 8.1 Enterprise, Enterprise N, Pro VL, and Pro N VL ISO from msdn.microsoft.com. Then upgraded my computer with that ISO. That was a mistake.
Now I want to download another version, but not sure what the differences are between Windows
8.1 Enterprise with Update (x64) - DVD (English) and Windows 8.1 with Update (multiple editions)
(x64) - DVD (English).
I'm getting confused with the Enterprise and non enterprise as an option. The goal for this computer I'm trying to get the right OS for is to work on development with visual studio/azure stuff, Adobe products, and ms office. Also, I want to have windows
media player included.
First question: if anyone could let me know which one will help me do my work better than the other I would really appreciate it.
Second question: is it possible to run a clean install over
Windows 8.1 Enterprise, Enterprise N, Pro VL, and Pro N VL and change it to either of the alternative options that I'm asking about in my first question?
Thank you for any help provided.

1. Windows 8.1 Enterprise w Update is the best. It allows you for sideloading in corporate environment without additional tools and licenses.
http://technet.microsoft.com/en-us/windows/jj874388.aspx
2. N series is for EU (without IE).
3. Profesional is fine, but you will need some tools to achieve the same functionality that you have in "pack" Enterprise.
4. VL is volume license, a type of license for multiple computers (to say it simply)
5. MSDN forum is better alternative for problems like this.
6. Attached to MSDN are licenses or at least references to web resources. Read license agreements carefully and let your installation and use follow the license.

How to best partition the HDD for dual boot: Windows 8 & Linux

Hi,
I'm a newbie in Windows 8, linux, Partition....
I would like to use my new laptop with windows 8 pre-installed to the following:
Create a Dual Boot Windows 8 / Ubuntu
Create on my C drive (unique drive on my laptop):
*a partition for the system
*one for Windows 8
*one for Data and
*last one for Ubuntu OS
My aim is :
-to install VmWare on Windows 8 and run Checkpoint Splat with virtual machines to perform CCSA labs.
to install GNS3 on Ubuntu for CCNP labs but with GNS3 accessing files in the Data partition
I have a Toshiba Satellite with 750Gb and 8 Go RAM.
According to you what's the best size for my partitions?
Is there a better way to partition my C drive regarding my aim?
Best Regards
***I don't know if it's the right section, sorry for that. Feel free to move this thread in the appropriate section***

Hi,
Thank you all,
Isn't it too much 200G for Windows as i will on ly install VMWARE Workstation 9 for lab purposes and possibly a few softwares.
VMWARE installed on Windows will require 2 GB + 1 GB per host (i will use approximatively 15 hosts).
Checkpoint products will be installed on VMWARE that is installed in Windows :
- disk space needed for 3 Checkpoint gateways: 3*37 GB
- disk space needed for 2 Checkpoint gateways management servers: 2*10 GB
On Linux I'll install GNS3 with 10 GB disk space required and a few softwares.
I've got a Toshiba stellite computer with Windows 8 pre-installed.
Processor: Intel(R) Core(TM) i5-3210M CPU @2.5 Ghz
RAM: 8 Go
64 bits OS, processor x64
See below the screenshot
I've taken screenshot of my partition (below).
* Don't take into account the disk 1 (E) partition
Can u confirm that in Disk o, partitions with 450 Mo, 260 Mo and 9.48 Go are for recovery system?
I am planning to let the recovery partition as it is and divide the TI30985500A (C) partition (688 Gb) into:
- 200 Gb windows partition
-100 Gb Linux partition
-388 Gb data partition
What do you think about this partionning regarding the informations i've provided above?

What is the difference between Constant Window, Variable Window,Main Window

hello all
what is the difference between 1) Constant Window
2) Variable Window
3) Main Window in SAP SCRIPT

Hi,
Window Types
When defining a form window, you must select a window type for the window.
You can choose between three types:
Constant Windows (CONST)
Variable Windows (VAR)
Main Windows (MAIN)
Constant Windows (CONST)
Starting with Release 4.0, the system internally processes windows of type CONST similar to windows of type VAR.
Therefore, if you create a new window, always use type VAR.
Variable Windows (VAR)
The contents of variable windows is processed again for each page, on which the window appears.
The system outputs only as much text as fits into the window. Text exceeding the window size is truncated;
the system does not trigger a page break. Unlike constant windows, the page windows declared as variable windows may have different sizes on different form pages.
As far as the processing of the window contents is concerned, the system currently treats constant and variable windows alike.
The only difference is that constant windows have the same size throughout the form.
Main Windows (MAIN)
Each form must have one window of type MAIN. Such a window is called the main window of the form.
For SAPscript forms, the main window has a central meaning:
It controls the page break.
It contains the text body that may cover several pages.
It allows to fix text elements at the upper and lower margins of the allocated page window (for example, for column headings).
As soon as a window of type MAIN is full, SAPscript automatically triggers a page break and continues to
output the remaining text in the main window of the subsequent page. Page windows of type MAIN have the same width throughout the form.
The SAPscript composer thus avoids reformatting of the text after each page break.
If a page does not have a main window, the system implicitly processes all other windows of the page and continues with the subsequent page.
This page must not call itself as subsequent page (recursive call), since this would produce an endless loop.
In such a case, SAPscript terminates the output after three subsequent pages.
For printing header lines or totals, the different output areas of the main window are of special importance.

Executing WINWORD from both Windows and linux using Java

Dear All,
I have a problem when trying to use Runtime class to execute a winword document. My code is as follows.
Runtime r= Runtime.getRuntime();
try{
r.exec("rundll32"+" "+"url.dll,FileProtocolHandler"+" "+"WINWORD"+ " "+"file://C://welkom.doc");
catch(Exception ex){
System.out.println("Unable to open the doc file:"+ex);
When I execute this swing application with the above, the program is unable to open the specific file. And it says "Problem with the short cut, unable to open the file". When I run the program without the file name, it opens a new doc file.
Attn: what I want to do here is I need to open the winword file from both windows and linux. So I cannot use the relative path of the WINWORD.exe file.
Can anyone help me?
Thanks in advance.
Regards,
Bala

If you take a look at the api, there's an exec(String[]) method. This is the one you should use when calling a command with multiple parameters.
so something like...
String[] cmd = new String[] {"rundll32", "url.dll,FileProtocolHandler", "WINWORD", "file://C://welkom.doc"}
r.exec(cmd);

10gR2 to 11gR2 from Windows to Linux with 6TB Database.

Hi,
I need to do migration from 10gR2 to 11.2.0.2.0 and from Windows to Linux for 6TB database Size. As both Endian format same, I did the migration using RMAN Convert database on UAT but for same 10gR2 version.(Both Source on Target Oracle Version was 10.2.01.0). Now I have to migrate from 10gR2 to 11.2.0.2.0. So it's 2 way process.
is it possible to club these 2 way migration process ???
Are following steps right or any modification is required ??
1) Install 11.2.0.2.0 on Linux OS
2) Open Source Database (Windows) in Read Only. Generate TRANSPORT.SQL, CONVERTSCRIPT.RMAN & Pfile.
3) Copy Source datafiles in temporary location on Target OS. Also copy above files.
4) Create dummy controlfile.
5) Startup nomount with Changed pfile
6) Mount database with Dummy Controlfile.
7) Run CONVERTSCRIPT.RMAN to convert actual datafiles from Windows Platform to Linux Platform.
8) Shutdown the instance and delele Dummy Controlfiles.
9) Edit TRANSPORT.SQL and do Appropriate Changes like redolog files, datafiles path...
Now my question is, can I add ?/rdbms/admin/catupgrd.sql in TRANSPORT.SQL script after Startup upgarade command so that Complete Upgradation to 11.2.0.2.0 would be done.
10) Then run TRANSPORT.SQL on Target System (11.2.0.2.0)
Tell me if more inputs are required from my side...

The directory structure is different...that's why you need to create the tablespaces in Linux. e.g. export dump says create tablespace in D:\..., there is no such thing in Linux. You can just export it, install software, create the db, tablespaces in Linux and import into the 10g in Linux.

File Path for Windows and Linux

hi can any one give solution how to implement code for odi file copy .
i am using Same Code for Windows and Linux
OdiFileCopy "-FILE=#Var_Lookup_File_Path \ Employee.csv" "-TOFILE=#Var_Lookup_File_Path_Backup\Employee.csv" "-RECURSE=NO" "-OVERWRITE=YES" "-CASESENS=NO"
the problem of above code is
it is working in windows but my Prod is Linux environment.
in linux \ not works.. / will work
please suggest how to concatnate variable and file without' \' '/'

Thanks Phani
i think in OS command also we may give path like #variable\File Name.
So how it will replace \ with / in Linux.
Could you give code for my Scenario..
Thanks for helping

Jdev 11g pre3 Preforms on Windows contra Linux

Have been working a lot with the Jdev 11g, think it is nice and easy to work with.
Except after a little time (or bigger project) it gets really slow, takes like 30sec, when changing a property and tabbing out. (If you look a the memory usage it runs around 2-4 GB, with only Jdev running plus standard Windows stuff)
Have now been trying on:
XP prod on a Dual Core Pc with 2 GB ram
Win 2003 Server – server with 8 gb ram
Now I tried to work a little with it on a Kubuntu (running on a virtual Pc 2007 (1 GB ram), and here it seem to a much small issue with the slowdown and with the memory usage.
Should there be a different between running Jdev 11g on a Window or Linux PC?
Have anyone tried to work a longer period on a Linux PC with JDev?

Hi,
note that the IDE performance issue is mentioned in the release notes of JDeveloper 11. It also mentions that this is an area that developers are looking at in a release version TP3. Performance should not vary too much between OS.

Native WIndows or Linux on XServer Hardware

Does anyone know if I can run Windows or Linux on the XServe natively without Leopard?
-Thanks

Hello Test Bed Fred, and welcome to the AppleBoards,
Assuming you are asking about Intel based current or recent Xserves you can run Windows using virtualization like Parallels Server BME, but you can't simply install it on the machine. You can also install and run a number of *nix flavors virtualized if you want to do that.
I'm sure there are *nix installs that can be run directly on the metal - the EFI boot is the only real technical hurdle that needs to be overcome. All that being said unless the machines are free I wouldn't generally choose to do this because you're paying Apple for software you won't use to get the hardware, but you can do whatever you want.
HTH,
