Verification properties in the CDQAV property set

The properties in the CDQAV property set determine how the Secure Agent reads address reference data files and allocates memory for address verification. Configure the properties in the Data Integration Server service on the Secure Agent on which you'll run address verification mappings.
The following table describes the properties:
Property
Description
LicenseFileDirectoryPath
Location of the license files that activate the address reference data. You might have more than one license file, for example, if you use batch reference data and geocoding reference data. You might have license files for a single country, for multiple countries, or for the entire world.
The Secure Agent uses the following location by default:
[Informatica_root_directory]/avLicenseFile
If you update the locaton, select a directory that the Secure Agent can read.
Note:
For mappings in advanced mode, you must set the license file location.
RefereceDataDirectoryPath
Location of the parent directory for the address reference data files.
Default location:
[Informatica_root_directory]/avdata
The reference data download process creates a FileSetA directory in the parent directory for the data files.
Do not configure a common reference data location for more than one Secure Agent if the Secure Agents run mappings on a combination of Microsoft Azure and non-Microsoft Azure pods.
Note:
In advanced mode, the Secure Agent determines the download location.
FullPreLoadCountries
List of countries for which all reference data, including geocoding data, is loaded into memory before address verification begins. Enter the three-character ISO country codes in a comma-separated list. For example, enter DEU, FRA, USA. Enter ALL to load all data sets. The property is empty by default.
Load the full reference database to increase performance. Some countries, such as the United States, have large databases that require significant amounts of memory.
The Secure Agent downloads reference data for every country that the property identifies.
PartialPreLoadCountries
List of countries for which reference metadata and indexing structures are loaded into memory before address verification begins. The property also applies to geocoding data files. Enter the three-character ISO country codes in a comma-separated list. For example, enter DEU, FRA, USA. Enter ALL to partially load all data sets.
When you run address verification mappings in a native runtime environment, the property is empty by default. When you run address verification mappings in an elastic runtime environment, the default is ALL. When you set the value to ALL, it partially loads all data sets.
Partial preloading increases performance when not enough memory is available to load the complete databases into memory.
The Secure Agent downloads reference data for every country that the property identifies.
NoPreLoadCountries
List of countries for which no reference data is loaded into memory before address verification begins. Enter the three-character ISO country codes in a comma-separated list. For example, enter DEU, FRA, USA.
When you run address verification mappings in a native runtime environment, the default is ALL. When you run address verification mappings in an elastic runtime environment, the property is empty by default.
The Secure Agent downloads reference data for every country that the property identifies. The default value indicates that the Secure Agent will download all address reference data.
MaximumMemoryinMegabytes
The total amount of memory, expressed in megabytes, that the address verification engine may allocate for data preloading and processing. Default is 1048.
When you run address verification mappings in an elastic runtime environment and set the value to ALL for PartialPreLoadCountries, the maximum memory required is 4400.
When you run address verification mappings in an elastic runtime environment and set the value to ALL for FullPreLoadCountries , the maximum memory required is 18000.
When you run address verification mappings in an elastic runtime environment and set the value to ALL for NoPreLoadCountries , the maximum memory required is 2700.
MaximumNumberofResults
The maximum number of addresses that a node in the runtime environment can return in a single thread. The default value is 100.
DownloadCASSData
Indicates whether the Secure Agent downloads CASS reference data files for certified United States address processing. You can download the CASS data if your Secure Agent is located in the United States.
Enter Yes if the Secure Agent is located in the United States and you want to download the CASS data. Otherwise, enter No. Default is No.
CertifiedReportLocation
Indicates the location to which the Secure Agent downloads a certified report when you select the Generate report option in a verifier asset. The default location is [Informatica_root_directory]/avreports' on the Secure Agent machine.
ParallelExecutionInstances
The number of threads that the Secure Agent can create for Verifier transformations at run time. Set the value to the maximum number of Verifier transformations that you expect to run in parallel in a single mapping. Default is 5.
Note:
Set a ParallelExecutionInstances value that is greater than or equal to the number of partitions on the Source transformation in the mapping.

Tuning the verification properties

You can update the Secure Agent properties that apply to address verification mappings to ensure that you derive the optimal performance from each mapping at run time. The Secure Agent properties work with the properties on the Source transformation in the mapping to determine mapping performance.
The Secure Agent properties and the mapping source properties define the following run-time conditions:
