Parameter Files in DVO

We can use parameter file in Informatica DVO while defining the where clause of either table pair or single pair. However there are certain rules in order to use.

We must add the parameters to the parameter file before we can add the parameters to a table pair or single table definition.

The parameters in the parameter file must be in the format
$$parameter name=value.

We need to place the parameter file in a location which is accessible by the Data Validation Option Client or DVOCmd that runs the tests.

If we specify the location of the parameter file in the Data Validation Option Client, enter the parameter file location as a network path.
Example, if the Informatica services runs on Windows, use the following syntax:
\\Host name of the Informatica services machine\shared folder path\parameter file name

If we specify the parameter file on a UNIX machine, the Data Validation Option Client on Windows cannot access the parameter file. In this case, we need to install DVOCmd on the UNIX machine and verify that DVOCmd has access to the parameter file.

We can use a parameter file for one or more table pairs and single tables.

Parameter file option is available if the user is having the enterprise license.

Steps to add a Parameter to a WHERE Clause in Table pair \ Single pair :

1.   We need enterprise license,to use a parameter in the WHERE clause to dynamically change the WHERE clause after each test run.

2.   Create the parameter file and add the parameters as per the above guidelines

3.   Place the parameter file in a location that is accessible by the Data Validation Option Client or the DVOCmd command line that runs the tests that require the parameters as per the above guidelines

4.   If the parameter file is kept on a UNIX machine, install DVOCmd on the UNIX machine and verify that DVOCmd has access to the parameter file.

5.   On the Advanced tab of a table pair or single table definition, specify the location and name of the parameter file.

6.   On the Advanced tab of a table pair or single table definition, specify the name, datatype, scale, and precision of each parameter.

What is Data Validation Option ? What can be tested ? To answer above two questions, Data Validation Option is a ETL Testing tool which comes along with power center and enables to test and validate data Data Validation Option reads table definitions from Power Center metadata repositories, and checks the data for inconsistencies Verify that moved or transformed data is complete and accurate and has not been changed because of errors in the movement or transformation process Will not check the correctness of transformations or mappings designed in Informatica Data Validation stages A typical workflow or stages for data validation consists of multiple tasks- 1. Data Validation Option reads one or more Power Center metadata repositories 2. We define the validation rules(creation of tests) in Data Validation Option 3. We run the rules(tests) to ensure the data conforms to the validation rules. When we do this, Data  Validation Option performs the following tasks: ...

Data ware house is relational database which is subject oriented, integrated, time-variant and nonvolatile collection of data used to support strategic decision making process Subject Oriented Data warehouses are designed to help you analyze data. For example, to learn more about your company's sales data, you can build a warehouse that concentrates on sales. Using this warehouse, you can answer questions like "Who was our best customer for this item last year?" This ability to define a data warehouse by subject matter, sales in this case, makes the data warehouse subject oriented. Integrated Integration is closely related to subject orientation. Data warehouses must put data from disparate sources into a consistent format. They must resolve such problems as naming conflicts and inconsistencies among units of measure. When they achieve this, they are said to be integrated. Nonvolatile Nonvolatile means that, once entered into the warehouse, data should not cha...
