Informatica PowerCenter Data Validation Option (DVO) Installation and Configuration – Part I

The illustration below explains the steps involved to install and configure the Informatica PowerCenter Data Validation Option for usage with Informatica PowerCenter installed on a local machine. The OS and software versions used for this illustration are as below: 1. Microsoft Windows XP SP3 (32-bit) 2. Microsoft SQL Server 2008 3. Informatica PowerCenter 9.1.0 HotFix2 4. Informatica PowerCenter Data Validation Option 9.1.4.2 The Informatica PowerCenter Server and Clients, PowerCenter DVO Client and Microsoft SQL Server 2008 are all installed on the same machine in this illustration. If the Informatica PowerCenter Server is installed on a machine other than the local machine, install the Data Validation Option on the same machine as the Informatica PowerCenter Clients. Note: The installation and configuration steps may differ for different versions of the DVO Client and different database types. In this illustration, Microsoft SQL Server 2008 is used as the database to create the Data Validation Option repository tables. Prerequisite Checks

• The machine that hosts Informatica Services must be installed and configured on the same local area network as the Data Validation Option Client machine.

• The Informatica domain must contain at least one PowerCenter Integration Service. • Install PowerCenter Client on the same machine where Data Validation Option will be installed. • Setup at least one PowerCenter repository.

System Permissions You require certain system permissions to complete Data Validation Option installation and configuration. To complete Data Validation Option setup, verify that you have the permission to complete the following tasks:

• Create a database, including the ability to create schemas, tables, indexes, sequences, and views. • Create a PowerCenter connection object in the Workflow Manager. • Create a folder in a PowerCenter repository in the Repository Manager. • Create and associate a PowerCenter Integration Service with the PowerCenter repository that the

Data Validation Option user can access. (This task can be performed by the Informatica PowerCenter Administrator).

• Copy a JAR file onto the machine that hosts Informatica Services. (This task can be performed by the Informatica PowerCenter Administrator).

• Configure the Administrator tool. (This task can be performed by the Informatica PowerCenter Administrator).

• Modify the environment variables on the machine where you install Data Validation Option. • Read and write on the Data Validation Option installation directory and subdirectories.

The installation and configuration steps are explained below. STEP-1: Creation of SQL user account for DVO repository

• For this illustration, a new database infa_dvo is created in SQL Server along with a SQL user account "infa". The database role membership assigned for the "infa" user on the infa_dvo database is db_owner as shown below.

• The infa_dvo database created will contain no database objects initially as shown below.

STEP-2: Verify if the PowerCenter Repository and Integration Services are running

• For this illustration, the Informatica PowerCenter Repository ServicePowerCenter_RS and the Integration Service PowerCenter_IS are created and running in the Informatica domain Domain_bi-7984eff67b9e.

STEP-3: Creation of Informatica PowerCenter User

• This step can be carried out with the help of the Informatica Administrator. The new Informatica user to be created should have privileges to create a folder in Informatica PowerCenter Repository Manager and to create a relational connection in Informatica Workflow Manager.

• For this illustration, an Informatica user "nelrick" is created using the Informatica Administrator in the Informatica PowerCenter repository PowerCenter_RS with the below roles.

• The privileges assigned to the Informatica user "nelrick" on selection of the above roles are shown below.

STEP-4: Creation of folder in Informatica PowerCenter Repository Manager

• Login to the Informatica PowerCenter repository from the PowerCenter Repository Manager tool using the Informatica login "nelrick" created in STEP-3.

• Create a folder DVO as shown below. This folder is needed for DVO to store the mappings, sessions and workflows that get generated while performing tests and to execute these tests. This folder is to be used specifically to store only the DVO mappings. Every DVO user must have the privileges to use this folder.

• The user "nelrick" has permissions on the DVO folder as shown below. Grant permissions to other users if needed on the DVO folder.

STEP-5: Creation of relational connection in Informatica Workflow Manager

• Login to the Informatica PowerCenter repository from the PowerCenter Workflow Manager tool using the Informatica login "nelrick".

• Create a relational connection INFA_DVO that points to the DVO repository databaseinfa_dvo created in STEP-1 with the SQL user account "infa" as shown below. This is needed for Informatica PowerCenter Integration Service to connect to the DVO repository to store the test results in the DVO repository tables.

STEP-6: Verify if domains.infa file is present on the machine where PowerCenter Clients are installed

• Check if the domains.infa file is available in the following location: \clients \PowerCenterClient\. • If the domains.infa file is not available on the PowerCenter Client machine,

copy the file from the following location on the PowerCenter server machine:installation directory>\

STEP-7: Creation of environment variable on DVO Client machine

• Create an environment variable called INFA_HOME and set the value to the location of the domains.infa file as shown below. Enter only the domains.infa file path, excluding the domains.infa filename, for the variable value as shown below. The value is C:\Informatica\9.1.0\clients\PowerCenterClient\ for this illustration.
