Oracle instance parameter
Oracle Instance Parameter are documented in the "NEXEED Industrial Application System" Operations Manual in the section "4.4.1. Oracle database - Instance parameters".
Securing data on the network (service to database)
Oracle supports two ways to encrypt the Data between Client and Database: Database Native Network Encryption and Transport Layer Security.
Since Transport Layer Security uses a Certificate that expires, we recommend Native Network Encryption.
The setting must be set on the Oracle Database in sql.net For details check the topic 18.3.2 in the Linked Documentation
