The Service Fabric cluster exists, the applications exists and are running. The user-assigned managed identity exists in the same resource group the cluster is. NOTE: I do not know how to verify whether it is assigned to the cluster or not.
Code is trying to create a Storage queues client using the identity and I get the error below, which I think means that the fabric:/System/ManagedIdentityTokenService is not running. NOTE: I do not know how to verify whether the service is running or not.
NOTE: Very similar code worked in other clusters.
NOTE: the underlying VMSS does have the managed identity associated to it.
NOTE: I am using Storage SDK 12. The C# code does the following:
ManagedIdentityCredentials cred = new ManagedIdentityCredentials(ClientId: "XYZ...");
string queueEndpoint = string.Format("https://{0}.queue.core.windows.net/{1}", accountName, queueName);
QueueClient qc = QueueClient(new Uri(queueEndpoint), cred);
bool b = await qc.CreateIfNotExistsAsync(); // This one throws the error below.
Any guidance to fix this issue would be appreciated.
Error:
Trying to create a queue (using MSI) failed with exception Azure.Identity.CredentialUnavailableException: No managed identity endpoint found.

I have been working with HFC SDK for Node.js and it used to work, but since last night I am having some problems.
When running helloblockchain.js only few times works, most time I get this error when it tries to enroll a new user:

Other times, the enroll works and the failure appears deploying the chaincode:

This code worked yesterday, so I don't know what could be happening.
Does anybody know how can I fix it?
Thanks,
Javier.

These types of intermittent issues are usually related to GRPC. An initial suggestion is to ensure that you are using at least GRPC version 1.0.0.
If you are using a Mac, then the maximum number of open file descriptors should be checked (using ulimit -n). Sometimes this is initially set to a low value such as 256, so increasing the value could help.
There are a couple of GRPC issues with similar symptoms.
https://github.com/grpc/grpc/issues/8732
https://github.com/grpc/grpc/issues/8839
https://github.com/grpc/grpc/issues/8382
There is a grpc.initial_reconnect_backoff_ms property that is mentioned in some of these issues. Increasing the value past the 1000 ms level might help reduce the frequency of issues. Below are instructions for how the helloblockchain.js file can be modified to set this property to a higher value.
Open the helloblockchain.js file in the Hyperledger Fabric Client example and find the enrollAndRegisterUsers function.
Add “grpc.initial_reconnect_backoff_ms": 5000 to the setMemberServicesUrl call.
chain.setMemberServicesUrl(ca_url, {
pem: cert, "grpc.initial_reconnect_backoff_ms": 5000
});
Add “grpc.initial_reconnect_backoff_ms": 5000 to the addPeer call.
chain.addPeer("grpcs://" + peers[i].discovery_host + ":" + peers[i].discovery_port,
{pem: cert, "grpc.initial_reconnect_backoff_ms": 5000
});
Note that setting the grpc.initial_reconnect_backoff_ms property may reduce the frequency of issues, but it will not necessarily eliminate all issues.
The connection to the eventhub that is made in the helloblockchain.js file can also be a factor. There is an earlier version of the Hyperledger Fabric Client that does not utilize the eventhub. This earlier version could be tried to determine if this makes a difference. After running git clone https://github.com/IBM-Blockchain/SDK-Demo.git, run git checkout b7d5195 to use this prior level. Before running node helloblockchain.js from a Node.js command window, the git status command can be used to check the code level that is being used.
I am trying to run REST API from Load Runner but unable to do it. Every times its throws below exception
Action.c(4): Error -26612: HTTP Status-Code=500 (Internal Server Error) for "http://ipaddress/LoyaltyApi/api1/loyaltycard/linkcard", Snapshot Info [MSH 1 1] [MsgId: MERR-26612]
My code :
Action()

"BodyFilePath=linkcards.json",
LAST);
return 0;
}
I have tested the same URL with POST parameter in POSTMAN and it's working fine without any issue.
I am very new in this technology so unable to solved the issue. Please help.

Assuming your management has moved you to this role, have they provided you with training on the tool and a mentor for a period of time. If not they have set you up for failure.
I am currently trying to replace Hypersonic with MS-SQL 2008 R2 in JBoss AS 5.1.0GA.
I have followed the instructions in the JBoss Server Configuration Guide, however the server fails to load with this error:
2013-09-26 17:06:04,479 WARN [org.jboss.resource.adapter.jms.inflow.JmsActivation] (WorkManager(2)-3) Failure in jms activation org.jboss.resource.adapter.jms.inflow.JmsActivationSpec#8bb1eb(ra=org.jboss.resource.adapter.jms.JmsResourceAdapter#c54851 destination=queue/iam/im/jms/queue/wpUtilQueue destinationType=javax.jms.Queue tx=true durable=false reconnect=10 provider=DefaultJMSProvider user=null maxMessages=1 minSession=1 maxSession=15 keepAlive=30000 useDLQ=true DLQHandler=org.jboss.resource.adapter.jms.inflow.dlq.GenericDLQHandler DLQJndiName=queue/DLQ DLQUser=null DLQMaxResent=10)
javax.naming.NameNotFoundException: DLQ not bound
(I left out the stack trace for brevity; it isn't important.)
I have checked, and DLQ is defined in destinations-service.xml
I'm not sure where to proceed from here; every response I can find on Google seems to suggest that defining the queue in destinations-service.xml has solved the issue for almost everyone.
Any help would be appreciated.
It turns out that the instructions in the Configuration Guide aren't 100% complete. The issue was that a ChannelFactory was referenced in the mssql-persistence-service.xml; however, this environment is not clustered, and so there were no ChannelFactory objects defined.
Removing the reference to the ChannelFactory was sufficient to resolve the issue.

This only happens for two customers. The install works OK for thousands of others. I have found numerous posts via google with no answer or generic "firewall is the issue" or "customer was using dialup".
Has anyone solved this? Is this a ClickOnce bug?
Disabling firewall software on the machine did not help because a hardware firewall installed on the network was the cause (FortiGate 30B).
I doubt that it's a bug. However, it seems like it gets stuck at one file in the deployment path. Maybe it is a type of file that is blocked by a firewall.
I would just remove all files but one from the build and see if that gets downloaded ok, and then add the rest of the files one by one (or maybe type by type) and see at what file ClickOnce gets stuck downloading.
If that doesn't seem to do anything, I'd build a dummy app and deploy it with ClickOnce and see if it installs at all on the customer's box.
