Hello friends, today we are going to learn about one more
SSIS task which is “Reorganize index task”.This task is more useful for DBAs, generally DBAs run a
query batch to reorganize indexes on production server in a scheduled manner.
Due to DML Operations (insert, update, delete), Indexes get fragmented and we
need to defragment the indexes by reorganizing or rebuilding the indexes. Lets
see how we can implement “Reorganize index task”.
First of all we will take a “Reorganize index task” in
control flow region(As shown below).
We will right click on the task and click on “Edit” menu
that will bring a new screen to us(Shown Below).
Now we will configure the server detail for which we want to
reorganize the indexes. To configure the server, we will click on the “New”
button(shown in the above screenshot) that will open up a new window(As shown
in the below screenshot).
In the “Connection Name” field , we will provide the
relevant name to the connection(In my case connection name is Myserver). In
second field “Select or enter a server name”, we will write the SQL Sever
name(In my case server name is Neeraj-PC). We can choose the server name by
clicking on the button(encircled by red color) that will bring a new screen
with the list of SQL server instances available(shown in the below screenshot).
We will
select any one server from the list of servers and click on “OK” button to save
the settings. After clicking on “OK” button we are back to the previous
screen(As shown below).
We have already defined the “Server Name”, now we will
provide the Database name in which we want to reorganize the indexes. To define
the database name, we will click on the combo box(indicated above by red arrow)
that will bring a new window(Shown below).
Below are the details for all
fields available in the above window.
All Databases: If we choose this
option, reorganize operation will be performed on all the databases available
on the server.
System databases: If we choose
this option, reorganize operation will be performed on only System
databases(Tempdb, Msdb, Master, Model).
All User databases: if we choose
this option, reorganize operation will be performed on all user databases
except(Tempdb, Master, Model, Msdb).
These Databases: if we choose
this option, we need to select those databases from the list on which we want
to perform the reorganize operation.
Ignore databases where the state
is not online: We should check this option this will prevent to perform
reorganize operation for offline databases.
We will click on the “OK” button
to save the settings and we will be back to the original screen.
Now, we need to specify the
objects on which we want to perform the reorganize operation. “View” option is
listed here to perform reorganize operation on “indexed Views”. I have selected
“Table” option in this example and after that we need to click on combo
box(indicated by red arrow).
As soon as we click on the combo
box, a new window will appear(As shown below).
In the above window either we can
specify “All objects” or specific table names. In my case only one table is
being shown, reason being I have only one table with index on it. We will click
on “OK” button to save the settings and then click “OK” further to close all
opened screen. We are done with our package, we will press “F5” key to run the
package and below is the result.
Green color of the task indicates
that our package ran successfully. I hope this article will help you in your
projects, please feel free to ask any question related to this article.
