Difference in Download Performance Rates Between Binary Files (IE mysql ibd) and Txt file

Hi !
i would thank you if anyone could clarify this to me .
im testing passing traffic from one DC to another DC .
if the file is a text file ie: SpeedTest.txt , i can download in about 20MB/s .
if the file is a binary file ie :SpeedTest.ibd (mysql) , i can download in about 2MB/s .
all tests were made using Rsync on Linux Machines . ( but it also happens with scp/sftp etc )
so i guess its something with encoding or perhaps hashing that is make per "chunk" ?
what is this happening , and if you know , what is the best way to pass binary files ? ( i use rsync because it use multiple sessions thus faster )
Thanks A lot !

Not sure about the exact differences but loading pdf files to view in a browser seems to have a high overhead (as in memory required to load and display the file). For that reason I prefer to view all pdf's in the reader. It's just quicker to load and smoother when scrolling to read.

Difference in data transfer rates between winXP and Linux server?

Hello all,
I am using a winXP laptop to act as my server (all usb external hard drives are connected to it) but the data transfer rates can be really slow. Is Linux faster in that regard? Can a Linux based server provide faster data transfer rates?
Thanks for any help.
Bmora96

Linux cannot make hardware go any faster - so if WinXP and its drivers are making optimal use of those USB drives and the USB data transfer pipe, Linux will not make it faster. (but installing Linux and going Tux are always excellent ideas that need no real reason either ;-) )
Real question you should be asking is if using a notebook in a server role is wise thing to do?

Difference between db file sequential read and scattered read

Hi,
Oracle Version : 10.2.0.1
Operating system: Linux
Can any one please help me what is the difference between db file sequential read and scattered read or please give any best related links .
Thanks & Regards,
Poorna Prasad.

>
A sequential read is a single-block read. Single block I/Os are usually the result of using indexes.
A db file scattered read issues a scattered read to read the data into multiple discontinuous memory locations. A scattered read is usually a multiblock read. It can occur for a fast full scan (of an index) in addition to a full table scan.

What is the difference between data file & control file

what is the difference between data file & control file

Dear Deba s
Control file
Every Oracle Database has a control file, which is a small binary file that records the physical structure of the database. The control file includes:
The database name
Names and locations of associated datafiles and redo log files
The timestamp of the database creation
The current log sequence number
Checkpoint information
For more info look into these
[Control File Basic|http://download-east.oracle.com/docs/cd/B19306_01/server.102/b14231/control.htm#i1006143]
Data File
You manage Data File in your Oracle database as part of Space Management. You can extend, create, drop, and alter tablespaces.
You especially need to avoid tablespace overflow, which is when a tablespace runs out of freespace in the allocated file or files. This happens when an object requires a new extent but there is either no freespace or insufficient freespace in the tablespace
For more info look into these links

Itunes won't download, binary file won't save to computer.

Every time I click on the "Download Now" button, I am able to select what folder I want to download the binary file to.
Once I click save, nothing else happens. I am taken to the "Thank you for downloading itunes" screen, but there is no record of my download anywhere, and the file is simply not saving.

So weird...I don't know why so many folks have this problem. Why won't the silly file download from Apple? When I click "save file" absolutely nothing happens. A dialogue box should pop up asking me where to save it.
My solution was to finally download it from one of the many file servers. I used one called "filehorse" and it downloaded right away.
How can one use their nifty iOS device if they can't install itunes on their computer?!
I tried the recommended "fixes", one of which included deleting the "temp" folder (which was not so easy to delete, required booting to safe mode command prompt) but made no difference. This was all using Firefox. IE is the only other browser on my computer, which seems to be permanently broken (most sites do not show properly even after using IE's "reset" feature).
I refuse to install Chrome, I tried it once and it sucked. Hopefully Apple will fix this silly issue so that next time I need to download iTunes, I can do it. Thank you!

Difference between image file and .bin file

I want to know whats the difference between img and bin file and which is better

Functionally and generically, they are the same thing for devices like routers and switches and firewalls ...
Some "images" consist of more than one binary file ... like code for specific blades or modules (like a radio module on an AP).
In most cases, it's just a naming convention and they are the same.
For some systems, like computers, a binary file is an executable ... it gets loaded into some flavor of memory, usually RAM, and the instructions are executed. During the initial load, some code is typically executed to initialize the various sub-systems. All of this initialization takes time (think about booting a desktop or laptop computer from power-on to "ready-to-go").
One way to speed things up a little is to save the initialized environment as an "image" or snapshot of the "ready-to-go" state of the device.
Once the snapshot is saved, it can be loaded directly into a block of memory without the need of all of the initialization code or interpretation of the binary code. This tends to make things "boot" faster. As long as the system's hardware configuration hasn't changed since the snapshot / image was taken, it should be exactly as if the device was never turned off. Some desktop and laptops have a "hibernate" mode .. everything is powered down, but it boots up as fast as the snapshot image can be pushed into the memory from the hard drive.
If you have a specific example, post it up.
Good Luck
Scott

How do i disable to pop up asking me if i want to save or cancel the binary file i am trying to download?

everytime i download a show or movie from the internet a pop up asks me:
"you have chosen to open xxxxxx which is a: Binary File from: httpxxxxx would you like to save this file - SAVE or CANCEL"
this never used to happen on the older versions of firefox. it is so annoying - is there any way to turn it off?
i am running mac os 10.5.8 and no, there is no option to click a 'don't ask me again' feature in the pop-up dialog.

I'd first try downloading an installer from the Apple website using a different web browser:
http://www.apple.com/quicktime/download/
If you use Firefox instead of IE for the download (or vice versa), do you get a working installer?

Issue in downloading Binary File on Safari 5 (MAC OS)

Hi,
We are working on an application, which download binary file when clicks the button, when i am using Safari 6 the below code snippet download file successfully.
Image:
Safari 6: on clicking Export file downloaded:
code:
String userAgent = request.getHeader("user-agent");
            if (userAgent.toLowerCase().indexOf("mac") >= 0) {
                response.setContentType("application/octet-stream");
            } else {
                response.setContentType(TEXT_CSV);
            // These Lines were added to make it work on the secure https
            // connection
            response.setHeader("Pragma", "public");
            response.setHeader("Cache-Control", "max-age=0");
            response.setHeader("Content-Disposition", "filename=contacts.csv");
but when we use safari 5 on MAC its not downloading the file, it simply display the content on browser it self
Image:
and file is not downloaded in this case, can some one tell what should be the contentType(""); should be set to download the file in Safari 5, so that the file can be downloaded in case of Safari 5.
Thanks in advance:)

You can set content type to:
response.setContentType("application/vnd.ms-excel");
file will download on safari 6

When trying to download it says binary file download and it starts but doesnt finish

as i try to download the little box pops up and says binary file save or cancel . So i save and it starts downloading the little line starts across and it gets to the end and disappears and leaves a empty box and nothing else happens

Which player? Do you mean Flash, or maybe the Windows Media Player plugin?

You have to run the installers with Firefox closed.

When I try to download a software up date for another program in Binary File (eg CCleaner or a Microsoft file) in FireFox they all just come up in the download window as 'Cancelled'? When I go to the destination folder the download file icon is there wit

When I try to download a software up date for another program in Binary File (eg. C Cleaner or a Microsoft file) in Firefox they all just come up in the download window as 'Canceled'? When I go to the destination folder the download file icon is there with 0 Kb's for size...Then when I click 'RETRY' the download it appears to download fully, but when I go into the destination folder the downloaded file is not there? I need to know if there is something in the Firefox options to resolve this problem or much more!!

If all .exe files are blocked, antivirus software is most likely configured to block them. See if you can download these with your antivirus and/or security software disabled.

Firefox crashed when I try to download a binary file

In this instance it is IE8 which I am trying to download (for business purposes I need Activex controls). When I currently open IE it runs as a process rather than an application. I have tried to download IE8 and google's Chrome but Firefox crashes as soon as I try to save the Binary files.

Sorry you are having problems. Can you give an example preferably of some small publicly available file and the site you are trying to download it from ?
As a simple example of a download (ok it is a .png image file not not a .exe file) but can you try to download a copy of your avtar/icon, as used on these forums. In Windows one method is that you right click & should get an option save. <br/> Mine alongside uses the link
* https://support.mozilla.com/media/uploads/avatars/avatar-257447.png
Are you able to download such an image, then see it in your download manager, and find it on your computer.
Once you have got Firefox to save your binary file you can use it. In the case of the .exe file you are trying to download that should be usable as intended with your Windows Operating System, the avatar also should be easily opened and viewed.
P.S.
You could try installing the add-on https://addons.mozilla.org/en-US/firefox/addon/opendownload-10902/ if you wished to adapt Firefox to run .exe files instead of just save them.

When I try to download a .exe file extension, Firefox designates it as a binary file which is useless to me.

using Windows 7 with i3 processor all the latest updates. Firefox is the ONLY browser that gives me this problem. I should not have to turn off my antivirus or go into my config files, write code or anything to have this simple task to work. If I buy a download for a program and get one shot at the download which is an executable file, I should not have it come up as a Binary file and can not use it to load the program that I just ordered.

Binary file corrupted when downloading

Hi. I'm trying to download binary files using a JSP. This is my code:
<%
     response.setContentType(report.getContent_type());
     response.setHeader ("Content-Disposition", "attachment;filename=\""+report.getNombre()+"\"");
     byte[] file = report.getFile();
     ServletOutputStream sos = response.getOutputStream();
     sos.write(file);
     sos.close();
%>
It seems to work, but when i'm going to open the downloaded file, it's corrupted, and when I compare it with the original one, all bytes that follow the first '\0' character have been replaced by '\0'. The file size is the same, but not the content.
I'm using Websphere as application server. Maybe this problem is related with the server, or maybe I'm doing something wrong. Any ideas?
Thanks.

I'm surprised that you didn't event get a IllegalStateException. Rather move all your logic to a servlet, jsps usually add whitespace where scriplets were and could corrupt your content.

Read binary files that are wraped in the downloaded executable signed jar

Hello, there:
I have created a Swing application and created a signed jar file and uploaded it to my site. The signed jar includes class packages, and a folder of binary files which are the datasource for my application.
jws downloads this signed executable jar, it'll automatically run it, but it has problems reading the binary folders wrapped in itself (the app is supposed to read the folder's structure and use the info to create a JTree object, and read the file's content as well). Is it the file path conversion problem? Do we need to use URL instead? I tried it after reading some threads on this forum but didn't make it.
As an alternatives, I want JWS to unjar the jar file and expand it to exploded files. I manually unjar it and run the app from command line, it works fine.
Plus, the app is supposed to manipulate the binary files when it's in process, like saving new content back to the files, zip the files and upload them to the remote sql server. therefore, I think it's easy to have it run when it's expanded.
So here is the question: JWS by default is running the executable jar, is there a way to tell JWS to unzip the jar and find the main class in the exploded files and run it?
Thanks a lot for your suggestions,
Sway

You can get to any resource in a jar file in your classpath. The code below will return InputStream for resource.bin nested two packages down.
InputStream in = YourClass.class.getResourceAsStream("/com/mypackage/resouce.bin"); //use '/' instead of '.'You can open a FileOutputStream to write that file.
OutputStream out = new FileOutputStream("myTempResource.bin");
IOUtil.streamAndClose(in,out);If the resouce is a nested zip or nested jar then you can use the Java Zip utilities to unwrap the stream.
