failed to add cache item with API

Question

hi,

when i use the downloaded sample code, i got exception when doing add method. it say:

Microsoft.ApplicationServer.Caching.DataCacheException was unhandled
  HelpLink=http://go.microsoft.com/fwlink/?LinkId=164049
  Message=ErrorCode<ERRCA0017>:SubStatus<ES0006>:There is a temporary failure. Please retry later. (One or more specified cache servers are unavailable, which could be caused by busy network or servers. For on-premises cache clusters, also verify the following conditions. Ensure that security permission has been granted for this client account, and check that the AppFabric Caching Service is allowed through the firewall on all cache hosts. Also the MaxBufferSize on the server must be greater than or equal to the serialized object size sent from the client.)

    ...

looks there is security issue, could you anyone point out i need to do next?

thanks.

Answer 1

Hi,

 Can you please paste the output of Get-CacheClusterHealth cmdlet in cache admin powershell and also the code snippet on how you're constructing the DataCacheFactory and DataCache ?

Answer 2

thank you look at this question, here it is.

PS C:\Windows\system32> Get-CacheClusterHealth

Cluster health statistics
=========================

HostName = SZDODEV02.morningstar.com
-------------------------

    NamedCache = Exp
        Healthy               = 34.38
        UnderReconfiguration  = 0.00
        NotPrimary            = 0.00
        InadequateSecondaries = 0.00
        Throttled             = 0.00

HostName = SZDOLAB93.morningstar.com
-------------------------

    NamedCache = Exp
        Healthy               = 31.25
        UnderReconfiguration  = 0.00
        NotPrimary            = 0.00
        InadequateSecondaries = 0.00
        Throttled             = 0.00

HostName = SZDOLAB94.morningstar.com
-------------------------

    NamedCache = Exp
        Healthy               = 34.38
        UnderReconfiguration  = 0.00
        NotPrimary            = 0.00
        InadequateSecondaries = 0.00
        Throttled             = 0.00

Unallocated named cache fractions
---------------------------------

i used the sample code from http://msdn.microsoft.com/en-us/library/hh351303

here is a piece:

            //Define Array for 1 Cache Host
            List<DataCacheServerEndpoint> servers = new List<DataCacheServerEndpoint>(1);

            //Specify Cache Host Details
            //  Parameter 1 = host name
            //  Parameter 2 = cache port number
            servers.Add(new DataCacheServerEndpoint("10.86.8.56", 22233));
            servers.Add(new DataCacheServerEndpoint("10.86.254.80", 22233));
            servers.Add(new DataCacheServerEndpoint("10.86.254.103", 22233));

            //Create cache configuration
            DataCacheFactoryConfiguration configuration = new DataCacheFactoryConfiguration();

            //Set the cache host(s)
            configuration.Servers = servers;
 
            configuration.SecurityProperties = new DataCacheSecurity();
            configuration.ChannelOpenTimeout = new TimeSpan(0, 2, 0);
            configuration.RequestTimeout = new TimeSpan(0, 1, 0);

           
            //Set default properties for local cache (local cache disabled)
            //configuration.LocalCacheProperties = new DataCacheLocalCacheProperties();

            //Disable exception messages since this sample works on a cache aside
            DataCacheClientLogManager.ChangeLogLevel(System.Diagnostics.TraceLevel.Off);

            //Pass configuration settings to cacheFactory constructor
            myCacheFactory = new DataCacheFactory(configuration);

            //Get reference to named cache called "Exp"
            myDefaultCache = myCacheFactory.GetCache("Exp");

///////////////////////////

I config the caching service again, this time it still get that exception. but I found there is a settings of DataCacheServiceAccountType, when I try to set this to DomainAccount, it works well. like below:

configuration.DataCacheServiceAccountType = DataCacheServiceAccountType.DomainAccount;

the Appfabric looks not easy to setup, it take me much time to get it works.
