Indexing the Databases

Index the databases referenced in a Mapping file you run the Match or Merge processes. While indexing the databases the UUID tool scans the data in each of the databases and loads the data into temporary files that are recorded in the Index Directory. If any changes are made to the database files or the Mapping file, then perform the index process again before you perform the Match or Merge process.

To index the databases

1. After setting the Working Directories, and defining the User Databases in the UUID tool, save the definitions as a Mapping file. If a Mapping file already exists click Load and load the mapping file into the UUID tool.
2. In the User Databases section of the UUID tool click Run Index.

   The UUID Index window opens and displays a progress bar for the index process. Depending on the size of your databases this process may take a couple of minutes.

   If an error occurs during the index process, an error message is issued as part of the progress report displayed in the lower part of the UUID Index window, and the cause of the error is indicated in the log file.

   If you neglected to Save the mapping file prior to trying to Run Index, a Save As window opens for you to save the file. After saving the file the UUID Index process begins automatically.

3. (Optional) To view a log of the index process click View Log to open the log. The log contains a line for each record that was scanned in each of the databases included in the mapping file.

   At the end of the progress display, the message Finished building Index files is displayed when the index is successfully built.

4. Click Done when the Index process is complete.
