Applies to:
Oracle Database – Enterprise Edition – Version 12.1.0.2 and laterLinux x86-64
Purpose
This note explains the requirements that need to be met for a successful installation ofOracle Database 12.1 release on Red Hat Enterprise Linux 7.0 or Oracle Linux 7 (or higher 7.x version) 64-bit (x86-64)
It is NOT the purpose of this NOTE to repeat every "how-to" step that is presented in theOracle Database 12.1 Installation Guide. 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 "Oracle Database Installation Guide 12c Release 1 (12.1) for Linux"
Scope
This procedure is meant for those Planning / InstallingOracle Database 12.1.0.2 on RHEL 7.0 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 7.0This procedure is not meant for those Planning / Installing Grid Infrastructure (GI) or any other Oracle products.
Details
Note that only Oracle db 12.1.0.2 is certified on RHEL 7 and Oracle Linux 7 (OL 7)
Requirements for installingOracle Database 12.1 release 64-bit on RHEL 7 or OL 7 64-bit (x86_64)
Before you proceed with Installation, please take time to review every below requirement carefully to avoid any obvious issues during Installation of binaries.1. Download theOracle Database 12.1 Software- Download theOracle Database 12.1 software from My Oracle SupportNote 1194734.1 Where do I find that on My Oracle Support (MOS) [Video]- After you download the Software, Verify the integrity of the Downloaded SoftwareNote 549617.1 How To Verify The Integrity Of A Patch/Software Download? [Video]
– If you have downloaded the Software on other Machine, please transfer the zip file on the Server being Installed using Binary Mode and unzip with the Oracle Software user.
I. Hardware:
1. Minimum Hardware Requirements
a.) Ensure that your system meets the following Physical Memory requirements: Minimum: 1 GB of RAM Recommended: 2 GB of RAM or more b.) Swap disk space proportional to the system’s physical memory as follows:
RAM
Swap Space
Between 1 GB and 2 GB
1.5 times the size of RAM
Between 2 GB and 16 GB
Equal to the size of RAM
More than 16 GB
16 GB
NOTE: The above recommendations (from the Oracle Database Installation Guide 12c Release 1 (12.1) for Linux) are MINIMUM recommendations for installations. Further RAM and swap space may be required to tune/improve RDBMS performance.
c.) 1.0 GB (1024MB) of disk space (and less than 2TB of disk space) in the /tmp directory.
If the free space available in the /tmp directory is less than what is required, then complete one of the following steps: – Delete unnecessary files from the /tmp directory to meet the disk space requirement. – Set the TMP and TMPDIR environment variables when setting the oracle user’s environment.
d.) Approximately 6.5 GB of local disk space for the Database Software Files.
e.) If you intend to create a preconfigured database during the installation, then the file system (or file systems) that you choose must have at least 2 GB of free disk space. For production databases, you must estimate the disk space requirement depending on the use of the database.2. Oracle Database is supported on ext2, ext3 and ext4 file systems (see Note:236826.1 for further information)
II. Software:
1. Certified Linux Operationg Systems
Oracle Linux 6, Oracle Linux 7 Red Hat Enterprise Linux 7
2. Oracle recommends that you install the Linux operating system with the default software packages (RPMs) (refer Figure 1) and do not customize the RPMs during installation. For additional information on "default-RPMs", please seeNote 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".
3. Linux Kernel Requirements
Oracle Linux 7
Oracle Linux 7 with the Unbreakable Enterprise kernel: 3.8.13-33.el7uek.x86_64 or laterOracle Linux 7 with the Red Hat Compatible kernel: 3.10.0-54.0.1.el7.x86_64 or later
Red Hat Enterprise Linux 7 – 3.10.0-54.0.1.el7.x86_64 or later
Note 1508516.1 Is It Mandatory To Install UEK Kernel Under RHEL?
4. Required OS Components (per Release Notes, and Install Guide)
