Effective in version 10.2 HotFix 1, the upgrade process and the HotFix installation process maintain the contents of the reference data properties files from an earlier PowerCenter version. You do not need to edit any reference data properties file after you install the HotFix or upgrade to version 10.2
PowerCenter reads configuration information for reference data from the following properties files:
AD50.cfg. Contains properties for address reference data.
CLASSIFIER.properties. Contains properties for classifier models.
IDQTx.cfg. Contains properties for identity populations.
NER.properties. Contains properties for probabilistic models.
The HotFix installation or upgrade process writes backup versions of the properties files to the Informatica 10.2
directories. The backup files are the default versions of the files and do not contain any value that you set in the earlier installation. Each backup file name ends with the extension .bak.
Previously, the upgrade operation renamed any reference data properties file that it found with the extension .bak. The upgrade operation also created default versions of any properties file that it renamed.
Previously, if you installed a HotFix for an installation, so that the Informatica directory structure did not change, the installation process preserved the AD50.cfg file. The HotFix installation otherwise added the extension .bak to each reference data properties file that it found and created a default version of each file.
