Update the Classifier Model and Probabilistic Model Property Files in PowerCenter

The PowerCenter Integration Service reads configuration settings for classifier model files and probabilistic model files from property files. The classifier model property file name is

CLASSIFIER.properties

. The probabilistic model property file name is

NER.properties

During the upgrade process, the installer writes empty property files to the following location:

<Informatica installation directory>/server/bin

If the installer finds a

CLASSIFIER.properties

file or

NER.properties

file at the location, it renames the files with the following names:

CLASSIFIER.properties.bak

NER.properties.bak

To maintain the classifier model and probabilistic model properties that you defined before you upgraded, update the upgrade files with the contents of the backup files. Or, delete the upgrade files, and remove the

bak

extension from the backup file names.
