I recently presented my views on upgrading to Oracle 19c to the DOAG community. As part of that I pointed out how easy it was to deploy the instant client on a VM using yum and dnf. I previously wrote about the installation of the instant client in an on-premises configuration.
This post describes the (admittedly short) procedure to deploy the current instant client to an Oracle Linux 8.3 installation. The steps in this post should also allow you to deploy the instant client in an on-premises environment the same way.
The OCI VM I created is as vanilla as it gets, I didn’t even put it under OS Management control.
Initial Deployment
After the VM has been provisioned, I found the following repositories enabled:
$ sudo dnf repolist repo id repo name ol8_MySQL80 MySQL 8.0 for Oracle Linux 8 (x86_64) ol8_UEKR6 Latest Unbreakable Enterprise Kernel Release 6 for Oracle Linux 8 (x86_64) ol8_addons Oracle Linux 8 Addons (x86_64) ol8_appstream Oracle Linux 8 Application Stream (x86_64) ol8_baseos_latest Oracle Linux 8 BaseOS Latest (x86_64) ol8_ksplice Ksplice for Oracle Linux 8 (x86_64) ol8_oci Oracle Linux 8 OCI Packages (x86_64) ol8_oci_included Oracle Software for OCI users on Oracle Linux 8 (x86_64)
A quick search for the instant client reveals the following hits:
$ sudo dnf search instantclient Last metadata expiration check: 0:22:35 ago on Fri 21 May 2021 06:38:23 GMT. =================================== Name Matched: instantclient ==================================== oracle-instantclient-release-el8.x86_64 : Oracle Instant Client yum repository configuration oracle-instantclient-release-el8.src : Oracle Instant Client yum repository configuration
That isn’t the actual instant client though:
$ sudo dnf info oracle-instantclient-release-el8 Last metadata expiration check: 0:23:34 ago on Fri 21 May 2021 06:38:23 GMT. Available Packages Name : oracle-instantclient-release-el8 Version : 1.0 Release : 1.el8 Architecture : src Size : 15 k Source : None Repository : ol8_baseos_latest Summary : Oracle Instant Client yum repository configuration License : GPLv2 Description : This package contains the Oracle Instant Client yum repository configuration.
Add the Repository
So let’s add the repository:
$ sudo dnf install oracle-instantclient-release-el8 Last metadata expiration check: 0:25:04 ago on Fri 21 May 2021 06:38:23 GMT. Dependencies resolved. ==================================================================================================== Package Architecture Version Repository Size ==================================================================================================== Installing: oracle-instantclient-release-el8 x86_64 1.0-1.el8 ol8_baseos_latest 16 k Transaction Summary ==================================================================================================== Install 1 Package Total download size: 16 k Installed size: 18 k Is this ok [y/N]: y Downloading Packages: oracle-instantclient-release-el8-1.0-1.el8.x86_64.rpm 212 kB/s | 16 kB 00:00 ---------------------------------------------------------------------------------------------------- Total 201 kB/s | 16 kB 00:00 Running transaction check Transaction check succeeded.

With the repository configuration in place I should be able to install the instant client next.
Installing the instant client
The next search for the instant client is more successful. The repository configuration is added automatically, refreshed, and dnf presented the following hits:
$ sudo dnf search instantclient Oracle Instant Client 21 for Oracle Linux 8 (x86_64) 17 kB/s | 4.2 kB 00:00 =================================== Name Matched: instantclient ==================================== oracle-instantclient-basic.x86_64 : Oracle Instant Client Basic package oracle-instantclient-basiclite.x86_64 : Oracle Instant Client Light package oracle-instantclient-devel.x86_64 : Development header files for Oracle Instant Client. oracle-instantclient-jdbc.x86_64 : Supplemental JDBC features for the Oracle Instant Client oracle-instantclient-odbc.x86_64 : Oracle Instant Client ODBC oracle-instantclient-release-el8.x86_64 : Oracle Instant Client yum repository configuration oracle-instantclient-release-el8.src : Oracle Instant Client yum repository configuration oracle-instantclient-sqlplus.x86_64 : Oracle Instant Client SQL*Plus package oracle-instantclient-tools.x86_64 : Tools for Oracle Instant Client
I wanted to use SQL*Plus, which should pull the dependent *basic package as well. And it does:

Thankfully, sqlplus is in the path, and can be executed without setting PATH, or LD_LIBRARY_PATH.

Nice! A quick check on yum.oracle.com reveals the same instant client is available over there, too.
Have fun!
