Requirements for installing Oracle Database 19c release(19.19 or higher) 64-bit on OL9 64-bit or RHEL9 (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.
- Download the Oracle Database 19c software(LINUX.X64_193000_db_home.zip) from OTN - https://www.oracle.com/technetwork/database/enterprise-edition/downloads/oracle19c-linux-5462157.html
- After you download the Software, Verify the integrity of the Downloaded Software
Note 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.
- Latest OPatch Utility
- Below Set of Fixes
- 19.22 List of Fixes
19.22 GI RU 35940989
For DB Installation - 19.22 DB RU 35943157 and 19.22 OCW RU 35967489 are required
For Client Installation - Only 19.22 DB RU 35943157
- 19.22 List of Fixes
Important Notes
- OCW MLRs are required to be applied even to SI DB Homes, because they contain Fixes necessary for the DB Home to support Installer prerequisite expectations for UEK and RHCK kernels on OL9. Same support is needed even for RHEL 9 also.
- Earlier listed Fixes for 19.19,19.20 and 19.21 have been withdrawn due a regression noticed in one of the Fixes and other Fixes are included in 19.22 RUs. Development strongly recommends applying 19.22(or newer) DB RU & OCW RUs to reduce the number of Fixes required for a certified/successful installation.
Hardware
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 space allocation relative to RAM
| RAM | Swap Space |
| Between 1 GB and 2 GB | 1.5 times the size of the RAM |
| Between 2 GB and 16 GB | Equal to the size of the RAM |
| More than 16 GB | 16 GB |
NOTE: The above recommendations (from the Oracle® Database Installation Guide 19c 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.
d. 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.
e. Approximately 7.2 GB of local disk space for the Database Software Files.
f. 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)
Software
Certified Operating System (Please see exact Requirements below)
Oracle Linux 9
Red Hat Enterprise Linux 9
a. For Minimal Linux Installation :
A minimal Linux installation option is either a custom installation where you select the Minimal option from Package Group Selection, or where you deselect all packages except for the Base pack. A minimal Linux installation lacks many RPMs required for database installation, so you must use an RPM package for your Oracle Linux release to install the required packages. The package you use depends on your Linux release
b. For a Default Linux Installation
Oracle recommends that you install your Linux operating system with the default software packages (RPMs).
A default Linux installation includes most of the required packages and helps you limit manual verification of package dependencies. Oracle recommends that you do not customize the RPMs during installation.
Kernel requirements
The following kernels are supported:
Oracle Linux 9 with the Unbreakable Enterprise Kernel 7: 5.15.0-1.43.4.2.el9uek.x86_64 or later
Oracle Linux 9 with the Red Hat Compatible Kernel: 5.14.0-70.22.1.0.2.el9_0.x86_64 or later
Red Hat Enterprise Linux 9: 5.14.0-70.22.1.0.2.el9_0.x86_64 or later
NUMA can be turned ON.No issues reported on OL/RHEL 9 when NUMA is ON.
Oracle Universal Installer requires an X Window System (for example, libx)
The libx packages are part of a default Linux installation.
If you perform an install on a system with a reduced set of packages, then you must ensure that libx or a similar X Window System package is installed
At least 1 GB of space in the /tmp directory.
Runlevel : 3 or 5
Oracle User Environment Configuration Checklist :
For new installs, if you have not configured an oraInventory directory, then the installer creates an Oracle inventory that is one directory level up from the Oracle base for the Oracle Grid Infrastructure install, and designates the installation owner's primary group as the Oracle Inventory group.
The oinstall group must be the primary group of all Oracle software installation owners on the server. It should be writable by any Oracle installation owner.
Oracle recommends that you create groups and user accounts required for your security plans before starting installation. Installation owners have resource limits settings and other requirements.
If you have an existing Oracle software installation, and you are using the same user to install this installation, then unset the following environment variables: $ORACLE_HOME,$ORA_NLS10, and $TNS_ADMIN, $ORACLE_BASE, $ORACLE_SID
By default, your operating system includes an entry in /etc/fstab to mount /dev/shm. However, if your Cluster Verification Utility (CVU) or Oracle Universal Installer (OUI) checks fail, ensure that the /dev/shm mount area is of type tmpfs and is mounted with the following options:
rw and exec permissions set on it
Without noexec or nosuid set on it
Set the default file mode creation mask (umask) to 022 in the shell startup file.
Storage Checklist for Oracle Database
At least 7.5 GB for Oracle Database Standard Edition 2.

Minimum Operating System Software/RPM Requirements
Note - The default RPM Versions that come with OL/RHEL 9 are OK.Hence,the minimum recommended versions for each RPM,have not been documented.This is an intended change with 19c.

Starting with 19c,Development has decided not to document the Package Versions anymore.
The RPM Versions that come with the certified minimum specified OS Version+Service Pack(i,e OL 9 OR RHEL 9) are all that are needed.
However,the Customers are free to update the RPMs to the latest versions.
The Oracle ORAchk utility provides system checks that can help to prevent issues before and after installation. These checks include kernel requirements, operating system resource allocations, and other system requirements.
Before you perform a fresh database installation:
./orachk -profile preinstall
Running Oracle Database Setup Wizard to Install Oracle Database
Log in as the Oracle installation owner user account (oracle) that you want to own the software binaries.
To install Oracle Database 19c on Oracle Linux 9 or Red Hat Enterprise Linux 9, Download the 19.3 Oracle Database software binaries from Oracle Technology Network (OTN), and then apply the 19.19 or 19.20 latest/newest Database Release Updates (DB RU) along with the respective One-Off Patches+Merge Patches+OCW Merge Patches during the the Oracle Database installation or upgrade process.
***Installation of the mentioned Patches is mandatory****
Create the Oracle home directory and extract the image files that you have downloaded in to this Oracle home directory. For example:
$ mkdir -p /u01/app/oracle/product/19c/dbhome_1
$ chgrp oinstall /u01/app/oracle/product/19c/dbhome_1
$ cd /u01/app/oracle/product/19c/dbhome_1
$ unzip -q /tmp/db_home.zip
The Oracle Database installation process involves the following Steps -
- Download latest OPatch from Patch 6880880. Once downloaded , Unzip into $ORACLE_HOME. Rename old OPatch Folder, Do not overwrite.
- Execute the runInstaller command with the -applyRU option to apply the 19.22 DB RU & OCW RU Patches and perform the Binary Installation -
19.22 GI RU Patch 35940989
$ export CV_ASSUME_DISTID=OL8
