APPLIES TO:

Oracle Database - Standard Edition - Version 11.2.0.4 to 11.2.0.4 [Release 11.2]
Oracle Database - Enterprise Edition - Version 11.2.0.4 to 11.2.0.4 [Release 11.2]
Linux x86-64

PURPOSE

This note explains the requirements that need to be met for a successful installation of Oracle 11gR2 RDBMS release 11.2.0.4 on Red Hat Enterprise Linux 7.0 (or higher 7.x version), 64-bit (x86-64).  These guidelines apply to cluster (RAC) or standalone / single instances.

It is NOT the purpose of this NOTE to repeat every "how-to" step that is presented in the 11gR2 Installation Guide manual. For example this NOTE does not include how to create the Linux OS account named "oracle", nor does it cover how to set environment variables. Both are adequately covered in Chapter 2 "Oracle Database Pre-installation Requirements" of the 11gR2 Installation Guide manual.

You can download Oracle 11.2.0.4 software from My Oracle Support (patch 13390677) 

SCOPE

 This procedure is meant for those planning/installing Oracle 11gR2 RDBMS release 11.2.0.4.0 (or higher 11.2.0.x version) on Red Hat Enterprise Linux 7.0 (or higher 7.x version) on the 64-bit (x86-64) platform. Since it is the expressed goal to keep Oracle Linux (OL) functionally IDENTICAL to RHEL, this NOTE is also completely applicable to 64-bit (x86-64) OL 7.0 (or higher 7.x version).

This procedure is not meant for those planning/installing Grid Infrastructure (GI) or any other Oracle products.
