Requirements for Installing Oracle 11.2.0.4 RDBMS on RHEL7 or OL7 64-bit (x86-64) (Document ID 1962100.1)

Applicable:
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 article explains what is required to successfully install Oracle database 11.2.0.4 on rhel7 (or higher 7.x version) 64-bit (x86-64.
These guidelines apply to cluster (RAC) or standalone/single instances.

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

Range:
Since it is the expressed goal to keep Oracle Linux (OL) functionally IDENTICAL to RHEL,
This article also applies to 64-bit (x86-64) OL 7.0 (or higher 7.x version ).

• Quickly build a Linux operating system + Oracle database environment
• Install Oracle 10g + RAC in RedHat 5.5
• Install Oracle 11gR2 (x64) in CentOS 6.4)
• Steps for installing Oracle 11gR2 in vmwarevm
• Install Oracle 11g XE R2 In Debian

This article does not apply to the installation and planning of GI or any other oracle products.
This procedure is not meant for those planning/installing Grid Infrastructure (GI) or any other Oracle products.
 
Details:
Installing Oracle 11gR2 RDBMS release 11.2.0.4 64-bit on RHEL7 or OL7 64-bit (x86_64) installation requirements are as follows

I. Hardware:
1. Minimum hardware requirements
A) at least 1 GB physical memory
B) swap meets the following requirements:
 

RAM	Swap Space
Between 1 GB and 2 GB	The size of RAM 1.5 times
Between 2 GB and 16 GB	Equal to the size of RAM
More than 16 GB	16 GB

Note: the recommendation above (from the 11.2 Database installation guide) is the lowest recommendation.
C)/tmp must have at least 1 GB space and less than 2 TB space.
D) database software requires at least 4 GB Space
E) The database must have at least GB space.
2. Oracle database is supported on ext2, ext3, ext4, and xfs file systems (see Note: 236826.1 and Note 1632127.1 for more information)

II software:
1. as is specified in section 1.3.2 of the Oracle Database Installation Guide for 11gR2 on Linux (part number E24321-02), Oracle recommends that you install the Linux operating system with the default software packages (RPMs) and do not customize the RPMs during installation. for additional information on "default-RPMs", please see Note 376183.1, "Defining a" default RPMs "installation of the rhel OS" or Note 401167.1, "Defining a" default RPMs "installation of the Oracle Enterprise Linux (OEL) OS ".
2. Red Hat Enterprise Linux Server 7.0 (or higher 7.x version) or Oracle Linux 7.0 (or higher 7.x version)
Note: RHEL7 servers must be running Red Hat kernel 3.10.0-54.0.1.el7 (x86_64) or higher or 3.8.13-33. el7uek (x86_64) or higher with UEK kernel.
OL7 servers must also be running kernel 3.8.13-33. el7uek (x86_64) or higher version. The product RHEL does not deliver UEK Kernel.
Only in OL 7 UEK and RHCK Kernel is supported ded.

3. Required OS Components
A) The exact version number details of this list are based upon 64-bit (x86_64) RHEL 7.0. when a higher "update" level is used, the RPM release numbers (such as 4.4.4-13) may be slightly different. since updates of RHEL 7 are certified, this is fine so long as you are still using 64-bit Linux (x86_64) RHEL 7 RPMs.
B) Some of the Install Guide requirements will already be present from the "default-RPMs" foundation of Linux that you started:

Binutils-2.23.52.0.1-12.el7.x86_64

4. Additional Required OS Components (per the runInstaller OUI)
A) intentionally blank

5. Additional Required OS Components (per this NOTE)
A) Please do not rush (rush), skip (skip), minimize (minimize) This key step. This list is based on 64bit "default-RPMs" installation.
Additional RPMs (beyond anything known to Oracle) may be needed if a "less-than-default-RPMs" installation of 64-bit (x86_64) RHEL Server 6 is already med. for more information, please refer to Note 376183.1, "Defining a" default RPMs "installation of the rhel OS" or Note 401167.1, "Defining a" default RPMs "installation of the Oracle Enterprise Linux (OEL) OS ".
B) Some RPM packages are pre-required RPM packages that need to be used as the RPM package list above:

Cpp-4.8.2-16.el7.x86_64
Glibc-headers-2.17-55.el7.x86_64
Mpfr-3.1.1-4.el7.x86_64

6. Oracle Global Customer Support (GCS) has noticed the recent trend, which is caused by the installation of too many rpm packages. For example:
A .) installing your own JDK version (prior to execute the Oracle Software runInstaller) is not needed on Linux, and is not recommended on Linux. A pre-existing JDK often interferes with the correct JDK that the Linux Oracle Software runInstaller will place and use.
B .) installing more than the required version of the gcc/g ++ RPMs often leads to accidentally using (aka enabling or activating) the incorrect one. if you have multiple RDBMS versions installed on the same Linux machine, then you will likely have to manage multiple versions of gcc/g ++. for more information, please see Note 444084.1, "Multiple gcc/g ++ Versions in Linux"
7. All RPM packages in II are in Red Hat Enterprise Linux 7 64-bit (x86_64) Release media.
