问题 I have a set of data which has a hierarchy of 3 levels. Each level has a name. I am looking at combining all of these names into a single string then creating a numeric hash that can be used as a hash key for a service fabric stateful service. I have seen lots online about finding data with keys but I am not sure how to actually create them in an efficient way. Ideally I would like a hash that is quick and easy to generate in SQL Server 2017 and C#. Can anyone point me in the right direction,

问题 Is it possible to periodically check the health of an application? I have two scenarios in mind: During deployment I want service fabric to rollback if the health check fails Application is successfully running but still want to periodically run a health check in case a dependency is unavailable Currently I expose a healthcheck operation and I have traffic manager polling it. I have the following to flag it as unhealthy.. var context = FabricRuntime.GetActivationContext(); context

问题 I am having a lot of issues upgrading a Service Fabric application. My original question is here. I am raising a new one now as this relates specifically to diff packaging. I have modified my package to remove the services I don't want to touch. But when I publish via Visual Studio, it does a full build. If I try to run the PowerShell script on its own by right clicking on it, it does not work: Cannot validate argument on parameter 'PublishProfileFile'. The "Test-Path $_ -PathType Leaf"

问题 After a Service Fabric Mesh Service has been deployed, how does one find the external facing IP Address. Things tried so far: Looking at the properties and settings of the service in the Azure portal Running the command az mesh app list - this shows a valid response but the IP Address is missing Running the command az mesh app show - this shows a valid response but the IP Address is missing Running the command az mesh service list - this shows a valid response but the IP Address is missing

问题 I have a system that uses stateless services hosted in Service Fabric This is running in a local dev cluster with 5 nodes Some of my services have InstanceCount set to -1 I was expecting to see multiple instances of the host executables to show in task manager but I only see 1 This is making me think there is only 1 instance Am I doing something wrong? Paul 回答1: There is not enough information to determine what the actual problem here is, but based on your description I might suspect of two

问题 I have a method in a Service Fabric Stateless Service (not an API) that sends a PING request to an external host. It works on my Local Service Fabric Cluster, but not on the actual cluster on Azure. I RDP'd to the cluster and pinged hosts, all of them resulted to "Request timed out". Anyone tried this before? I'm playing around the cluster's Firewall. 回答1: ICMP is blocked inside Azure. You can use PSPing to check connectivity though. More info here. Because the ICMP protocol is not permitted

问题 I have a stateful service in Service Fabric with multiple partitions and replicas. I have configured it so that both the Primary and ActiveSecondary replicas expose their endpoints. The purpose is so that I can leverage the secondary replicas for read operations. The problem I'm having is that inside the service I want to be able to tell it is a Primary or ActiveSecondary because some shared defaulting code needs to not run for the secondary replicas. (Because inserting defaults into the

问题 I have tried to upgrade to the ne version of the Service Fabric preview code - 1.4.87-preview - and everything seems to have gone ok, but when I try to deploy a service I get an exception on run telling me that it cannot find FabricRuntime.dll. This goes both for my upgraded project, for newly created test projects and for all samples. I can see that the DLL is present on the machine and that a system PATH has been set to the directory containing it. There seems to be nothing wrong with my

问题 I have an IReliableDictionary and need to take the items in the dictionary and move them in to an IList to return from my reliable service. It seems I can't do a .ToList of any kind, so I'm sure I'm approaching it wrong. public async Task<IList<CustomerOrderItem>> GetOrdersAsync() { IReliableDictionary<CustomerOrderItemId, CustomerOrderItem> orderItems = await this.StateManager.GetOrAddAsync<IReliableDictionary<CustomerOrderItemId, CustomerOrderItem>>(CustomerOrderItemDictionaryName);

问题 This question is continuation from previous thread. store cancellation tokens in service fabric services Opened a new thread because answering this question would not be trivial. To summarize what has been discussed regarding cancel a job / task running in particular service in some partition of service fabric: Cancellation Token limitation: Cancellation token works within the service partition and that is the limitation in partition-wise storing the instances, probably the reason why
