Before you use Dynamic Data Masking to mask data for a database that uses a JDBC connection, you must configure the client.
The Dynamic Data Masking installation contains a .jar file that you must save on the client machine. The .jar file contains a Java agent, a transformer that intercepts the method calls of JDBC objects, and proxy classes for JDBC classes. You can find the .jar file in the following location:
<Dynamic Data Masking installation>\Wrappers\jdbc\GenericJDBC.jar
You must perform additional configuration steps based on the client and operating system.
Because the client looks for the Dynamic Data Masking service on the host and port, the client connection fails when the Dynamic Data Masking Server is down. To connect to the database, the Dynamic Data Masking Server must be running.
