SSIS Template to create Log file if not Exists and Delete Log file after Redention period

Here i want to explain you how to create a Log file if it is not exists and Delete Logfile after redention Period .

There are 2 major steps in this Template

1) Create Log file If not  with the Name <<SSIS Package name>>_YYYY-MM.log
2)Delete The Log file which is Older that Redention Period

To achive this we need 3 Parameters

1.SSIS_ErrorLog_Folder :  To indicate the Log file folder path
2.Log fileName :  To store the Logfile name . Here we want to craate File name which inculdes Cureent Year month  . we will keep log file on monthly basis and we have redention period of 2 months

 Expression to Createa logfile is

@[User::SSIS_ErrorLog_Folder] + @[System::PackageName]+ "_" +
(DT_WSTR,4)YEAR(GETDATE()) + "-" + RIGHT("0" + (DT_WSTR,2)MONTH(GETDATE()), 2)+ ".log"

The result will look like

\\SurendraThota\Dev\Logs\Package_2014-03.log



3.DeleteLogFileName : This variable is get the Logfile name of  last 2 months back  which will be used in deleteing that file from the log file folder .  This will used for better maintaining log file folder space .

 The expression we need to Use is

@[User::SSIS_ErrorLog_Folder] + @[System::PackageName]+ "_" +
(DT_WSTR,4)YEAR(DATEADD( "month",- 2, getdate() )) + "-" + RIGHT("0" + (DT_WSTR,2)MONTH(DATEADD( "month",- 2, getdate() )), 2)+ ".log"

\\SurendraThota\Dev\Logs\Package_2014-01.log


now we have created all the required variables

next we need to create Script task to Create Logfile if not exists and Delete if the log file exists after redention period . Use the below script to achieve this


Public Sub Main()

If (File.Exists(Dts.Variables("LogFileName").Value)) Then
         Dts.TaskResult = ScriptResults.SuccessElseFile.Create(Dts.Variables("LogFileName").Value)
End If
   If (File.Exists(Dts.Variables("DeleteLogFileName").Value)) Then
     File.Delete(Dts.Variables("DeleteLogFileName").Value)
End IfDts.TaskResult = ScriptResults.SuccessEnd Sub
End Class

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) <
