Advanced Properties for a Table Pair

Advanced Properties for a Table Pair

You can configure bad records, a parameter file, sampling, and caching for a table pair. The properties vary based on the types of objects you select for the table pair.

Bad Records

You can configure the following properties for bad records:
Save All Bad Records for Test Execution
Saves all bad records for value, outer value, and set tests for table pairs.
Write Bad Records to:
The location where Data Validation Option writes bad records. You can select one of the following options:
  • Flat File. Data Validation Option writes bad records to the specified flat file.
  • DVO Schema. Data Validation Option writes bad records to the Data Validation Option repository.
File Name
The location and name of the flat file to which Data Validation Option writes bad records. Default location is
$INFA_HOME/server/infa_shared/BadFiles/<single table name /table pair name>/<file name>
.

Parameters

Parameter File
Name of the parameter file. Click
Add
to add a parameter file. Click
Delete
to delete the selected parameter file.

Data Sampling

You can configure the following properties for data sampling:
Enable Data Sampling
Indicator that determines if data sampling is enabled.
Apply Sampling on:
The table on which you want to apply sampling.
Percentage of Rows
Percentage of rows that you want to sample. Minimum value is .000001. Maximum value is less than 100.
Seed Value
The starting value used to generate a random number for sampling. You can enter a seed value for the following platforms:
  • PowerCenter. Minimum is 0. Maximum is 4294967295.
  • IBM DB2. Minimum is 1 - 10³¹. Maximum is 10³¹ - 1.
  • Oracle. Minimum is -2,147,483,648. Maximum is 2,147,483,647.
Use Native Sampling
The database performs the sampling. If you do not enable this option, PowerCenter performs the sampling.

Cache Size

Cache Size
Total cache used to run a PowerCenter session associated with the table pair. By default, the units are bytes. Append KB, MB, or GB to the value to specify other units. For example, you can specify 1048576, 1024 KB, or 1 MB. Select
Automatic
to enable PowerCenter to compute the cache size.
