Manually Downloading and Installing Oracle Instant Client RPM Packages

An alternative to 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 package. 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.

Install the packages using yum for Oracle Linux 7 and dnf for Oracle Linux 8 and Oracle Linux 9. For example:

For Oracle Linux 8 and Oracle Linux 9 on Linux x86-64:

$ sudo dnf install oracle-instantclient19.27-basic-19.27.0.0.0-1.x86_64.rpm

For Oracle Linux 7 on Linux x86-64:

$ sudo yum install oracle-instantclient19.27-basic-19.27.0.0.0-1.x86_64.rpm

For Oracle Linux 8 on Linux for Arm (aarch64):

$ sudo dnf install oracle-instantclient19.27-basic-19.27.0.0.0-1.aarch64.rpm

For Oracle Linux 7 on Linux for Arm (aarch64):

$ sudo yum install oracle-instantclient19.10-basic-19.10.0.0.0-1.aarch64.rpm

Additionally, 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/19.27/client64/lib/network/admin or /usr/lib/oracle/19.10/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 to install the package and then update your PATH environment variable. For example:

For Oracle Linux 8 and Oracle Linux 9:
```
$ export PATH=/usr/lib/oracle/19.27/client64/bin:$PATH
```
For Oracle Linux 7:
```
$ export PATH=/usr/lib/oracle/19.10/client64/bin:$PATH
```
