In this blog post I show how to install Oracle Java on Oracle Linux running in an OCI compute shape by using RPMs available yum servers available within OCI. I...

In a previous blog post, I described how to quickly create an Autonomous Database and connect to it via SQLcl. By using the the most recent Cloud Developer Image —which includes SQLcl- I was able to save a time installing and configuring. Cloud Developer Image also comes with Oracle SQL Developer pre-installed. In this post I describe how to run SQL Developer and connect it to Autonomous Database. Steps Launch Cloud Developer Image Set up OCI cli Create Autonomous Transaction...

In this blog post, I describe how to use a free trial for Oracle Cloud and the recently released, Oracle Linux-based Cloud Developer Image to provision an Autonomous Transaction Processing Database and connect to it via SQLcl, all in a matter of minutes. Think of the Cloud Developer Image as a Swiss army knife for Cloud developers. It has a ton of tools pre-installed, including: Languages and Oracle Database Connectors Java Platform Standard Edition (Java SE) 8, 11 and 12 Python...

Thanks to Chuck Anderson, Linux kernel developer, Oracle, for compiling the information in this post. Enhancements to mainline Linux continue at a steady pace, though we don’t always hear a lot about this work. With the 5.1 release upon us, we wanted to give a shout out to some important and notable additions that the 5.0 release brought to bear. Some we chose because our kernel developers are directly involved, some because they affect Oracle workloads, and others simply...

This post was updated on 20 March, 2019 to reflect changes in the way yum configuration works.   A few months ago we added dedicated repositories for Node.js to the Oracle Linux yum server. These repos also include an RPM with the Oracle Database driver for Node.js, node-oracledb, so you can connect your Node.js application to the Oracle Database. In this post I describe the steps to install Node.js 10 and node-oracledb Node.js to Oracle Database. If you are in a rush or want...

Introduction One of Oracle’s top 10 predictions for developers in 2019 was that a hybrid model that falls between virtual machines and containers will rise in popularity for deploying applications. Kata Containers are a relatively new technology that combine the speed of development and deployment of (Docker) containers with the isolation of virtual machines. In the Oracle Linux and virtualization team we have been investigating Kata Containers and have recently released...

About OCI Utilities Instances created in Oracle Cloud Infrastructure using Oracle-Provided Images based on Oracle Linux include a pre-installed set of utilities that are designed to make it easier to work with Oracle Linux images. This is a quick blog post to demonstrate how the oci-metadata command included in OCI Utilities make quick work of accessing instance metadata. Update - March 4th, 2019: This post was updated to include the --value-only option As of this writing, the...

Given that we just released Go programming language RPMs on Oracle Linux yum server, I figured it would be a good opportunity to take the goracle driver for a spin on Oracle Linux and connect a Go program to Oracle Database. goracle implements a Go database/sql driver for Oracle Database using ODPI-C (Oracle Database Programming Interface for C) 1. Enable Required Repositories to install Go and Oracle Instant Client First, install the necessary release RPMs to configure Yum...
