SSIS Error Code 0xC002F304 and its solution

Error code :

Code: 0xC002F304     Source: Web Service Task Web Service Task     Description: An error occurred with the following error message: "Microsoft.SqlServer.Dts.Tasks.WebServiceTask.WebserviceTaskException: Could not generate the proxy for the specified Web service. The following errors were encountered while generating the proxy: Source file 'C:\Windows\TEMP\2d0vea3n.0.cs' could not be found  No inputs specified  .     at Microsoft.SqlServer.Dts.Tasks.WebServiceTask.WebServiceTaskUtil.Invoke(DTSWebMethodInfo methodInfo, String serviceName, Object connection, VariableDispenser taskVariableDispenser)     at Microsoft.SqlServer.Dts.Tasks.WebServiceTask.WebServiceTask.executeThread()".  End Error  Error: 2010-12-03 11:09:52.72  

When it will Occur :
 when we are using web service Task in ssis package and that package is used to create a Sql agent Job.

Soltion :
we need to Make sure that the account that the job is running under (the proxy account) has write permissions to C:\Windows\TEMP.

If support team is not agreeing to do any writes on System folder .

web service task will use the temp directory settings from the user’s profile/environment (%TEMP%). We need to  specify a new directory by changing the TEMP environment variable value for the user account running the package.


To move the TEMP/TMP folders in a clustered environment
1.     Log on to a node in the cluster as the Cluster service account.
2.     Right-click My Computer and select Properties.
3.     Select Advanced.
4.     Click Environment Variables.
5.     In the User variables for <account name> area, select TEMP and click Edit.
6.     In the Variable value field, enter the new path for the TEMP environment variable and click OK.
7.     In the User variables for <account name> area, select TMP and click Edit.
8.     In the Variable value field, enter the new path for the TMP environment variable and click OK.
9.     Click OK to close the Environment Variables dialog box and OK once more to close the System Properties dialog box.
10.  Restart the node to apply the change.
11.  Repeat steps 1 through 10 for each node in the cluster.
12.   
The solution for the issue is we need to set the Temp variable path of the Account with which the Job runs  to the Desired location apart from System folders. There is an issue with Web service task . The web service task internally takes the Temp environment variable path to store the 1.dll file , 1 .out file and 1 .err file . after the Package suceesfully executed the .dll file is removing by the package , but the other 2 files are left at that folder . if we are executing frequently the files will occupy the entire temp folder . The web service Task should remove the other 2 files also when it is executed successfully .  Microsoft need to handle this in next version.

SSAS : A connection cannot be made to redirector. Ensure that 'SQL Browser' service is running. (Microsoft.AnalysisServices.AdomdClient). + Solution

Problem : have installed Analysis service on my server machine through remote login from my service account. I am able to open Analysis services from there. When I open SSMS from the same service account on my local machine, I am not able to connect to that Analysis service. It is giving me error by saying : "A connection cannot be made to redirector. Ensure that 'SQL Browser' service is running. (Microsoft.AnalysisServices.AdomdClient). A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connection host has failed to respond 10.245.192.111:2382(System)." Solution : Based on my research, the issue was caused by the Browser Service account was changed to the domain account. In your scenario, you can try to connect to the Analysis Service using <Servername>:2383 instead of instance name. Or you can change the Browser Service account to "Local System".

SSIS Error : Unable to infer the XSD from the XML file. The XML contains multiple namespaces

Image
Problem : When we have Multiple Namespaces in the Xml Source which we need to load the Data from   as we shown below Then we will face a issue in generating XSD for that XML Error : Unable to infer the XSD from the XML file. The XML contains multiple namespaces. (Microsoft Visual Studio) Solution : First we need to avoid multiple namespaces to transform your source file to a format that doesn’t refer to the namespaces. SSIS has an XML task that can do the transformation. 1) Add the XML task to an SSIS   Control Flow and edit it. 2) Change the OperationType property value to XSLT, the SourceType to File connection and the Source to your source file that has the problem. 3) Set the SaveOperationResult property to True and expand the OperationResult branch. Set DestinationType to File Connection and the Destination to a new XML file ( ModifiedInput.XML). 4) Add the below script to a new file and save it with an xslt file extension (Input.XSLT) <
