Hi Jose,
If you recently purchased Oracle Standard for DLP, I recommend you download the 19c version of Oracle. The file name will either be WINDOWS.X64_193000_db_home.zip or LINUX.X64_193000_db_home.zip, depending on what OS platform you plan to install it to.
Here is a link for the
DLP Oracle 19c Implementation guide that has instructions for installing the database needed for the DLP Enforce. Note that the database creation process uses some template files provided by Symantec, so make sure that in your product downloads portal that you also pull down 19.3.0.0_64_bit_Installation_Tools_Windows.zip or 19.3.0.0_64_bit_Installation_Tools_Linux.tar.gz (again, depending on what platform you are installing the database to).
Here are links to the installation guides for
DLP 15.7 on Windows and
DLP 15.7 on Linux, depending on what OS platform you will be installing DLP Enforce to.
