Identity Population Data Requirements

A mapping that performs identity match analysis reads reference data files called identity populations. You purchase and download the identity population files from Informatica. Copy the population files to the PowerCenter Integration Service machine or to a shared directory on a machine that the PowerCenter Integration Service can access.

You must copy or install the population files to a directory with the name

default

The PowerCenter Integration Service can read the location of the population file directory from the

IDQTx.cfg

configuration file or from the SSAPR environment variable. The PowerCenter Integration Service looks for the location in the

IDQTx.cfg

file. If the

IDQTx.cfg

file is not present or does not specify a location, the PowerCenter Integration Service looks for the location in the SSAPR environment variable.

The

IDQTx.cfg

file and the SSAPR environment variable specify the path to the parent directory of the

default

directory. The path does not include the directory name.

The PowerCenter installer writes the

IDQTx.cfg

file to the following path:

[PowerCenter_Installation]/server/bin

The

IDQTx.cfg

file uses the IdentityReferenceDataLocation property to specify the location of the population file directory. Update the property with the current location of the directory.

For example, you might set the following path on the IdentityReferenceDataLocation property:

[PowerCenter_Installation]/services/DQContent/INFA_Content/identity/

You can set an absolute path or a relative path to the default directory on the IdentityReferenceDataLocation property. Set an absolute path to a directory on the PowerCenter Integration Service machine or to a shared directory on a machine that the service can access. Set a relative path to a directory on the PowerCenter Integration Service machine.

The PowerCenter Integration Service reads a relative path from the following directory:

[PowerCenter_Installation]/server/bin

For example, to specify a relative path to a population file directory in the

bin

directory, set the following relative path:

IDQTx.cfg Properties

When you set the IdentityReferenceDataLocation property in the

IDQTx.cfg

file, you can also set the following properties:

IdentityCacheDir: Path to the directory that stores temporary data files created when the mapping runs. The path identifies a parent directory. The PowerCenter Integration Service writes the temporary files to directories below the location that you specify.; The property has the following default value:; ./identityCache
IdentityIndexDir: Path to the directory that contains the temporary index files created when the mapping runs. Identity match analysis uses the index to sort records into groups before match analysis. The path identifies a parent directory. The PowerCenter Integration Service writes the index files to directories below the location that you specify.; The property has the following default value:; ./identityIndex

A Developer tool user can set the cache directory path and the index directory path in the Match transformation. The PowerCenter Integration Service uses the path in the

IDQTx.cfg

file if the Match transformation does not specify the path.
