How can i prove rac on linux is better than on windows ?

Hi all,
Is there any document or any thread on this forum which will help me prove that RAC on linux is better than on windows. Actually i did not recommend to my management windows os for RAC, now the management wants the reason why did not recommend windows. I want some sort of proof or any document to prove my point. Please help ......

> now the management wants the reason why did not recommend windows
Then give them reasons. TCO. In-house experience and skills with Linux. Official support from vendors like Sun for Linux on their servers. Linux being used as the core development platform for Oracle. Linux proven as a cluster-based operating system - it leads the supercomputer/cluster market by a significant percentage.
According to www.top500.org (listing the 500 fastest/biggest computers clusters on this planet)*:
Operating System Family Top500
Linux 85.20 %
Mixed 6.80 %
Unix 6.00 %
Windows 1.20 %
BSD Based 0.40 %
Mac OS 0.40 %
* (In other words, if Linux is good enough to run 85% of the world's fastest computers, it is more than good enough to run your company's RAC)
There are numerous sound reasons for choosing Linux over Windows. But do not make performance claims that you cannot ever hope to backup with technical evidence.

I cannot find my receipt for my ipod how can i prove it isnt a year old

I cannot find my receipt for my ipod and its under a year old how can i prove this

Hi cantfindanything,
I am gathering you are trying to get an iPod repaired by Apple.
In the US for iPod Touch Generation 5:
Every iPod comes with a one-year limited warranty and 90 days of complimentary telephone technical support.
If you are trying to get a replacement or repair job, Apple will just need your Serial Number, found on either the back of your iPod Touch or in: Settings, General, About, Serial Number.
When Apple receives this number, their database will be able to show up your information including device purchase and activation.
To get a repair job/replacement, it is best to talk to Apple on the phone or go to your nearest Apple store to find out possible resolutions.
To contact Apple call:
1-800-MY-APPLE
You can also take the iPod into your closest Apple Store and give them your serial number and they will be able to help you: http://www.apple.com/retail/storelist/
Many Thanks for your question and Happy New Year!

Hi, China6450.
Thank you for visiting Apple Support Communities.
I would recommend setting up Manually manage music. This will only allow music to be synced from the computer to the iPod nano. Here are some helpful articles that will walk you through the process.

How can we use Custom MessageBox in SelectionChangedEvent of LongListSelector for Windows Phone 8

Dear Sir/Madam,
How can we use Custom MessageBox in SelectionChangedEvent of LongListSelector for Windows Phone 8.
Actually my problem is that When i am using Custom MessageBox in SelectionChangedEvent of LongListSelector,when i am click Open(Left Button) it's working fine and navigated correctly,But when i am Click the No(Right Button) then it stayed in same page
but all that page is in stuckup i mean that page is not working and not doing any event.
My C#.net Code
private async void userPageLongListSelector_SelectionChanged(object sender, SelectionChangedEventArgs e)
if (e.AddedItems.Count > 0)
if (userPageLongListSelector.SelectedItem == null)
return;
if (dbTenMin == null)
dbTenMin = new Database(ApplicationData.Current.LocalFolder, "tenMInDBSchema.db");
await dbTenMin.OpenAsync();
var res = (sender as LongListSelector).SelectedItem as _10Min._10MinClass.minUserPages;
var resIndex = (sender as LongListSelector).ItemsSource.IndexOf(userPageLongListSelector.SelectedItem);
string selectedPageName = res.userPages.ToString();
string selectedPageDesignUser = res.pageDesignUser.ToString();
int selectedIndex = resIndex;
CustomMessageBox messageBox = new CustomMessageBox()
Caption = "Message...!",
Message = "This form need offline datalist,Please load now.",
LeftButtonContent = "Open",
RightButtonContent = "No"
messageBox.Dismissed += (s1, e1) =>
switch (e1.Result)
case CustomMessageBoxResult.LeftButton:
string uidAndpwd = _10MinClass._10MinStaticClass.csUidAndPwd.ToString();
_10MinClass._10MinStaticClass.csDataListPageDetails = selectedPageDataDetailsForSchema.ToString();
_10MinClass._10MinStaticClass.csAllDataLists = offlineDataBaseDataListNam;
_10MinClass._10MinStaticClass.csNotCreatedSchemaNameOfDBList = notCreatedDataLists;
userPageLongListSelector.SelectedItem = null;
if (dbTenMin != null)
dbTenMin.Dispose();
dbTenMin = null;
NavigationService.Navigate(new Uri("/10MinformDataList.xaml", UriKind.Relative));
else
NavigationService.Navigate(new Uri("/10MinformDataList.xaml", UriKind.Relative));
break;
case CustomMessageBoxResult.RightButton:
break;
case CustomMessageBoxResult.None:
break;
default:
break;
messageBox.Show();
Same custom messagebox code working in Phone_BackKeyPress event i am writing the code in Right Button that e.OriginalSource.ToString(); then it is working fine.
But It is not working in Selection Changed Event in LongListSelector control in Windows Phone 8.
Please help me,as soon as possible.
Thanks & Regards,
SrinivaaS.

What happens if you leave the implementation for LeftButton empty as well , does the page gets stuck in that case also, if you press left button?
i.e.
CustomMessageBox messageBox = new CustomMessageBox()
Caption = "Message...!",
Message = "This form need offline datalist,Please load now.",
LeftButtonContent = "Open",
RightButtonContent = "No"
messageBox.Dismissed += (s1, e1) =>
switch (e1.Result)
case CustomMessageBoxResult.LeftButton:
break;
case CustomMessageBoxResult.RightButton:
break;
case CustomMessageBoxResult.None:
break;
default:
break;
messageBox.Show();

Purchases made under 1 Apple ID are permanently associated with that Apple ID and CANNOT be transferred to another Apple ID. So if you want to keep those songs, you'll need to always have access to your dad's account.

How can I print a prn file on HP6500; I have windows xp

How can I print a prn file on HP6500; I have windows xp

Perhaps some additional information would be helpful. Does the HP6500 refer to a printer? If yes, is the print driver and software installed on the computer that has XP? I assume "prn" refers to some picture file or not?

how can I connect two thunderbolt monitors to my macmini in windows 8 and bootcamp? Works fine in OSX

Did you try to hook up both monitors to the Belkin adaptor? Trying will determine if your monitor has a bad input port. See if the Belkin adaptor is the problem. I have never used that specific adaptor, but I have always had luck with the Dr. Bott's DVI for ADC adaptor. Best of luck.

I'm not concerned about sending to the long address list. I just can't get the email and window that says "cannot send emai using the server..." to go away. The default must be "retry", because although I cannot see the choices at the bottom of the window if I hit return it trys again... and then of course comes back with the very long pop up window that I cannot see the bottom of so I can tell it to quit trying...

How can i restrict a user not open more than 3 sessions in database

how can i restrict a user not open more than 3 sessions in database.For this i have already create a profile and set CONCURRENT_SESSIONS=3 and assing that profile to user but the problem is there.

You will simply need to use the following parameter in your CREATE PROFILE syntax.
CREATE PROFILE normal_user
LIMIT SESSIONS_PER_USER 2;
but the resource limits set for a profile are enforced only when you enable resource limitation for the associated database.
you could do this either by having an initialization paramater which will invoke as soon as the database starts or try using ALTER SYSTEM command
