Linux installation client oracle
Oracle Database Client installation software is available in multiple media, and can be installed using several options.
The Oracle Database Client software is available on installation media, or you can download it from the Oracle Technology Network website, or the Oracle Software Delivery Cloud portal. In most cases, you use the graphical user interface (GUI) provided by Oracle Universal Installer (OUI) to install the software. However, you can also use Oracle Universal Installer to complete silent mode installations, without using the GUI.
You cannot use Oracle Universal Installer from an earlier Oracle release to install components from this release.

Removing Earlier Oracle Instant Client Installations
Remove any earlier installations of Oracle Instant Client using yum before you start a fresh installation.
- List the currently installed Oracle Instant Client packages. For example: For Oracle Linux 7:
$ sudo yum list installed | grep instantclient$ sudo dnf list installed | grep instantclientoracle-instantclient19.5-basic.x86_64 19.5.0.0.0-1 @/oracle-instantclient19.5-basic-19.5.0.0.0-1.x86_64$ sudo yum remove oracle-instantclient19.5-basic.x86_64$ sudo dnf remove oracle-instantclient19.5-basic.x86_64$ sudo yum remove oracle-release-el7$ sudo dnf remove oracle-release-el8Installing Oracle Instant Client From the yum Server
If you are using Oracle Linux and have configured your Oracle Linux yum server, then you can install Oracle Instant Client using the yum install command.
- Install the Oracle Linux release package to configure repository definitions for Oracle Instant Client: For Oracle Linux 7:
$ sudo yum install oracle-instantclient-release-el7$ sudo dnf install oracle-instantclient-release-el8$ sudo yum install oracle-instantclient-basic$ sudo dnf install oracle-instantclient-basic$ sudo yum install oracle-instantclient-sqlplus$ sudo dnf install oracle-instantclient-sqlplusUsing versionlock to Avoid Upgrades
To ensure that you do not inadvertently upgrade Oracle Instant Client when a new major release is published, use yum versionlock after you have installed Oracle Instant Client 21c.
$ sudo yum install yum-plugin-versionlock$ sudo yum versionlock oracle-instantclient-release-el7$ sudo dnf versionlock oracle-instantclient-release-el8Configuring yum versionlock still allows automatic Oracle Instant Client release updates to 21.2, 21.3, and so on.
Manually Downloading and Installing Oracle Instant Client RPM Packages
An alternative method for installing Oracle Instant Client is to manually download and install the Oracle Instant Client packages.
- Go to the Oracle Instant Client Downloads page: https://www.oracle.com/database/technologies/instant-client/downloads.html
- Download the desired Oracle Instant Client RPM packages. Select the correct platform, architecture, and packages of your choice. For example, if your application is 64-bit, then ensure that you select 64-bit Instant Client and download the Basic Package RPM file. All installations require a Basic or Basic Light package. All other packages are optional.
- Install the packages using yum . For Oracle Linux 7:
$ sudo yum install oracle-instantclient-basic-21.3.0.0.0-1.x86_64.rpm$ sudo dnf install oracle-instantclient-basic-21.3.0.0.0-1.el8.x86_64.rpmAdditionally, you may have to perform the following tasks before you start your application:
- If you intend to colocate optional Oracle configuration files such as tnsnames.ora , sqlnet.ora , ldap.ora , or oraaccess.xml with Oracle Instant Client, then move these files to the /usr/lib/oracle/21/client64/lib/network/admin subdirectory. This is the default Oracle configuration directory for applications linked with this Oracle Instant Client. Alternatively, you can move the Oracle configuration files to another, accessible directory. Then set the environment variable TNS_ADMIN to that directory name.
- To use binaries from the tools package, use yum or dnf to install the package and then update your PATH environment variable. For example:
$ export PATH=/usr/lib/oracle/21/client64/bin:$PATH
