Processing Options for SSAS Objects

PROCESSING OPTION SSAS2008

Process Default: (Applicable for **All objects)
Performs the minimum number of tasks required to fully initialize the object. The server converts this option to one of the other options based on the object state.

Process Full (Applicable for All objects)
Drops the object stores and rebuilds the object. Metadata changes, such as adding a new attribute to a dimension, require Process Full.

Process Update (Only for Dimensions) 
Applies member inserts, deletes, and updates without invalidating the affected cubes.

Process Add (Only for Dimension & Partition)
Adds only new data.

Process Data (Dimension, cube, measure group, partition)

Loads the object with data without building indexes and aggregations.

Process Index(Dimension, cube, measure group, partition)
Retains data and builds only indexes and aggregations.

Unprocess (All Objects) 
Deletes the object data or the data in the containing objects.

Process Structure ( Only CUBE)
Deletes the partition data and applies Process Default to the cube dimensions.

Script task recompilation Error

A package that has a script task runs fine in visual studio, but the package fails as a job with following error on DEV Server.

"Script could not be recompiled or run: Attempted to read or write protected memory. This is often an indication that other memory is corrupt"

OR

“Error 1 Validation error. Script Task : The task is configured to pre-compile the script, but binary code is not found. Please visit the IDE in Script Task Editor by clicking Design Script button to cause binary code to be generated.”

Answer:

• Check the pre-complied property of script task.
• Change it to TRUE
• Add the following code in your script, before imports statement.

                    Option Strict Off

                    Option Explicit On
                    Imports System

                    .

Checking for the file?

Question:

Many times I observed on MSDN SSIS forum that developers are facing problem for checking the file in a particular folder. There are 2 types of checking:

1> Is any file exist in the folder?

OR

Count number of files in a directory through SSIS

2> A particular file is exist [for example c:\Manish\demo.txt]

Answer:

1> Is any file exist in the folder? OR Count number of files in a directory through SSIS?

For checking the file existence in a directory, there are 2 ways

1: File Property task

File Properties Task .  It will detect file existence. Check the link.

2: Script task

Step1: Take a ForEachLoop container.

Step2: Map to the particular directory.

Step3: Inside that you have to use a script task and there you can write following code to count the no of files.

Step4: Define the following variable @ package level 

User::Count

---------------------------
|   ForEachLoop             |
---------------------------
|
|            --------------
|            |Script Task |
|            --------------
|
---------------------------

Step5:

Public Sub Main()

    Dts.Variables("User::Count").Value = Dts.Variables("User::Count").Value + 1

    MsgBox(Dts.Variables("User::Count").Value.ToString())

    Dts.TaskResult = ScriptResults.Success

End Sub

    
Now you can access the count variable

2> A particular file is exist [for example c:\Manish\demo.txt]

You can use a script task to check if the file exists or not. Suppose I have demo.txt in C:\Manish then I will use a script task with code as:

Public Class ScriptMain

    Dim flag As Boolean

    Public Sub Main()

        flag = File.Exists("C:\MyFolder\demo.txt")

        If flag = True Then

            System.Windows.Forms.MessageBox.Show("File Exists")

        End If

    Dts.TaskResult = Dts.Results.Success

    End Sub

End Clas

Divide Single column to multiple columns

Question:
I have a column as : act=TUNING; svid=629; VCN=180; TI=949290689; TO=949291183; TT=494; FPID=(586653033-494)
Now i want to take the values of svid,VCN,TI,TO,TT,FPID into seperate columns.
How can i do it in ssis.
The column sizes are not standard all the time.
In one of my table in the DB , i have the token strings like token1 => svid= and token2 => ;
So now how can i use these tokens to pull the data of 629. 

Please check the above question @msdn forum

Answer:

Please write the following expression in your derived column (C2 is column name)
(click on the image for larger view)

After this you just need to replace the following with the blank string
act =
svid =
TT=
TI=
TO=

Load MS Access data to SQL server

Question: How to transfer MS Access data to Sql Server 2005?

Answer:
There are 2 ways for achieving this
1) SSMS: Import & Export Wizard
2) BIDS: Create a New SSIS package

First approach is easy and gives you flexibility to modify the SSIS package(If required)
I hope you can try this your self .

Let me know if you need my help for this.

Second approach: 
Open the BIDS and create a new package

Step1:
a) Create a new OLE DB Source connection.
b) Select the provider as "Native OLE DB\ Microsoft Jet 4.0 OLE DB Provider".
c) Select the Database file name. [Check the Image Below]

Step2:
a) Take a DFT.
b) In DFT drag "OLE DB Source", "OLE DB Destination" [or take any destination as per your requirement]
[Check the Image below]

Step3:
Before executing the package please makes sure that destination table should have the correct data type. [if not use data conversion task]


I hope this will help you. If you need more assistance or clarification, please leave the comment.
