问题 I am experiencing an intermittent issue with SQL Azure. I am copying a readonly SQL Azure database (V12) from one elastic pool into another. Once the database is copied, I set it to read/write using: $"ALTER DATABASE [{databaseName}] SET READ_WRITE" This sometimes fails with the error: The operation cannot be performed on database *** because it is involved in a database mirroring session or an availability group I have tried implementing retry logic with backoff but that doesn't work. I have

Availability of Azure storage account

由 百般思念 提交于 2019-12-24 13:06:03
问题 This page says that the availability of an azure storage account is computed as (billable requests)/(total requests). Billable requests mean all the requests excluding those which experienced anonymous failures (except network errors), throttled requests, server timeout errors and unknown errors. Now,what I see on the azure portal for my storage account is a straight line continuously at 100%, meaning that the account is available at 100% availability continuously. The line is without any

Towards understanding availability of xdg-open

由 北城余情 提交于 2019-12-24 04:45:08
问题 I want to open an image, and in Windows I do: #include <windows.h> .. ShellExecute(NULL, "open", "https://gsamaras.files.wordpress.com/2018/11/chronosgod.png", NULL, NULL, SW_SHOWNORMAL); I would like to use a Linux approach, where it's so much easier to run something on the fly. Example: char s[100]; snprintf(s, sizeof s, "%s %s", "xdg-open", "https://gsamaras.files.wordpress.com/2018/11/chronosgod.png"); system(s); In my Ubuntu, it works. However, when running that in Wandbox ( Live Demo ),

Use different implementations of a class depending on iOS version?

由 北战南征 提交于 2019-12-11 01:27:25
问题 iOS 11 recently added a new feature I would like to use but I still need to support older versions of iOS. Is there a way to write the same class twice and have newer versions of iOS use one version of the class and older versions of iOS use the other? (Note: Originally I used if #available(iOS 11, *) but I had to use it in so many places that I thought it would just be cleaner to have 2 versions of the class if possible. Maybe there's a way of using @availble somehow? I was focused on using

How should applciation using active/passive redundant model be containerized using kubernetes?

由 对着背影说爱祢 提交于 2019-12-10 15:17:03
问题 I have an distibuted application running on virtual machines, among which I have one service running on active/passive mode. The active VM provides service via a public IP. Should the active VM fail, the public IP will be moved to the passive VM and the passive VM will become active and starts to provide service. How this pattern fit in containerized application managed by kubernetes? If I use replication controller with replicas =1, in case of node/minion failure, replication controller will

Objective-C @available guard AND'ed with more conditions

由 可紊 提交于 2019-11-30 14:35:18
问题 Objective-C has an @available expression in XCode 9+ / LLVM 5+ that allows you to guard a block of code to at least a certain OS version so that it won't emit unguarded availability warnings if you use APIs that are only available on that OS version. The problem is that this availability guarding is that it only works if it's the sole expression in the condition of an if . If you use it in any other context, you get a warning: @available does not guard availability here; use if (@available)

The problem is that this availability guarding is that it only works if it's the sole expression in the condition of an if .

CAP theorem - Availability and Partition Tolerance

由 流过昼夜 提交于 2019-11-27 16:34:45
While I try to understand the "Availability" (A) and "Partition tolerance" (P) in CAP, I found it difficult to understand the explanations from various articles. I get a feeling that A and P can go together (I know this is not the case, and that's why I fail to understand!). Explaining in simple terms, what are A and P and the difference between them? Chris Heald Consistency means that data is the same across the cluster, so you can read or write from/to any node and get the same data. Availability means the ability to access the cluster even if a node in the cluster goes down. Partition
