If you install Dynamic Data Masking on UNIX, verify that the machine where you perform the installation has Java SE 8.
The Dynamic Data Masking installer, Dynamic Data Masking Server, and Management Console require Java Development Kit (JDK) SE 8 to run. On UNIX, you must install Java SE 8 before you start the installation so that the Dynamic Data Masking installer runs properly. The Java directory must be in the system path.
On Windows or Linux, you do not need to install Java. The Dynamic Data Masking installer contains the Java SE 8 files.
