Why JDBC Thin Client Connections With TLS 1.2 Fail With Jan 2020 PSU Patch 30340202 And Succeed With Aug 2017 PSU Patch26609783 (Doc ID 2661741.1)

Last updated on APRIL 21, 2020

Applies to:

JDBC - Version 12.1.0.2.0 and later
Information in this document applies to any platform.

Goal

JAN 2020 PSU <Patch:30340202> was applied to database version 12.1.0.2.0.. After successfully applying the patch, an application using TLS 1.2 with JDBC 12.1.0.2 (ojdbc7.jar) is unable to connect to the database. At that time, changing TLS version to 1.1 solved the connection issue.
TLS 1.2 connections with AUG 2017 PSU (PSU Database Patch Set Update : 12.1.0.2.170814 (26609783) ) were working fine before the application of the JAN 2020 PSU patch.
Why is the application unable to connect to database after JAN 2020 PSU was applied?
