Is it possible to upgrade to Data Loss Prevention (DLP) 15.8 from Oracle 188.8.131.52, or does Oracle need to be upgraded to 19c first?
As per the DLP System Requirements and 15.7 MP1 Release Notes, Oracle 184.108.40.206 is not supported in DLP 15.8.
Starting with DLP 15.8, Oracle 12c (version 220.127.116.11) is not supported.
DLP 15.8 requires Oracle 12.1 or Oracle 19c (Standard or Enterprise edition).
Although the System Requirements documentation states "The Symantec Data Loss Prevention database schema is supported on all editions of Oracle." - schema support only extends to supported versions of Oracle, such as 12c (18.104.22.168) and 19c. Supported editions do not include deprecated versions (such as 11g, 10g, or 22.214.171.124).
Further clarification of our support policies, specifically in relation to the Database version for DLP, can be found in the following KB article:
If you are currently running Oracle 12.2.x, you can perform a dbupgrade or dbexport / import to Oracle 19c.
