EM 12c: Configure Enterprise Manager 12c Cloud Control to Accept Connections with TLSv1.0 Protocol

(Doc ID 1602983.1)

Last updated on DECEMBER 27, 2017

Applies to:

Enterprise Manager Base Platform - Version and later
Information in this document applies to any platform.


Enterprise Manager Cloud Control can use either the http or https protocol for communication between

1) Browser clients and OMS
2) OMS and Agent

When https is used for communication, the client and server can negotiate to use a particular SSL protocol version such as SSLv2, SSLv3, TLSv1 for the communication. By default, the OMS server does not accept connections using SSLv2 but accepts SSL connections using SSLv3 or TLSv1, as negotiated during the SSL handshake with the client.

This document provides the steps for configuring the OMS,Agent and WLS in EM 12c setup to accept connections only using TLSv1.0 protocol, which is the highest supported protocol with EM 12c.

Configuring TLSv1 only mode is also required to overcome POODLE Vulnerability

Note : For TLS versions 1.1 and 1.2, JDK 7 is needed. However EM 12.1.0.x has been certified only with JDK 6 and not with JDK 7. Using TLS 1.1 & 1.2 is supported with EM 13c, which uses JDK 7.
Details are in:
