MySQL HeatWave integrates GenAI capabilities into MySQL on OCI. We have demonstrated how HeatWave GenAI can leverage RAG’s capability to utilize ingested documents (unstructured data) in LakeHouse and generate responses to specific questions or chats. See: The common theme here is the use of data stored in Object Storage (LakeHouse). I previously discussed how to […]

In the previous post, we saw how to deploy MySQL HeatWave on Amazon. Multicloud refers to the coordinated use of cloud services from multiple providers. In addition to our previous post, where we deployed MySQL HeatWave on Amazon, we will explore how to connect with another cloud service. Oracle has partnered with Microsoft to offer […]

Yesterday I participated to the Oracle Technology Roundtable for Digital Natives in Zurich.

It was a good opportunity to learn more about AI, Cloud and HeatWave with the focus on very trendy features of this product: generative AI, machine learning, vector processing, analytics and transaction processing across data in Data Lake and MySQL databases.

It was also great to share moments with the Oracle and MySQL teams and meet customers which gave feedback and tips about their solutions already in place in this area.

I’ll try to summarize below some key take-away of each session.

Unlocking Innovation: How Oracle AI is Shaping the Future of Business (by Jürgen Wirtgen)

AI is not a new topic. But how do we …

Multicloud is a cloud adoption strategy that utilizes services from multiple cloud providers rather than relying on just one. This approach enables organizations to take advantage of the best services for specific tasks, enhances resilience, and helps reduce costs. Additionally, a multicloud strategy offers the flexibility necessary to meet regulatory requirements and increases options for […]

MySQL 9.0.0 has brought the VECTOR datatype to your favorite Open Source Database. There are already some functions available to deal with those vectors: This post will show how to deal with vectors and create our own functions to create operations between vectors. We will use the MLE Component capability to create JavaScript functions. JS […]

MySQL HeatWave 9.0 was released under the banner of artificial intelligence. It includes a VECTOR datatype and can easily process and analyze vast amounts of proprietary unstructured documents in object storage, using HeatWave GenAI and Lakehouse. Oracle Cloud Infrastructure also provides a wonderful GenAI Service, and in this post, we will see how to use […]

In MySQL HeatWave, the Database as a Service (DBaaS) offered by Oracle, Machine Learning is incorporated to provide database administrators (DBAs) and developers with an optimal experience.

Those tools are the Auto ML advisors like the autopilot indexing for example.

MySQL HeatWave is also an invaluable asset for Data Analysts, offering straightforward tools that streamline the process of creating predictive models through data training and scoring.

The Data

The data we are using is the Bank Marketing data related to marketing campaigns over phone calls of a Portuguese banking …

MySQL HeatWave is the MySQL DBaaS provided by Oracle in OCI and some other clouds. Compared to the vanilla MySQL, one of the key features of the service is that it allows you to run analytics queries (aka OLAP) very quickly using the HeatWave cluster. You can also run such queries on files using LakeHouse.

When we talk about analytics, we also think about data visualization solutions. In OCI, you can use Oracle Analytics Cloud.

In this article, we explore the procedure to establish a connection between Oracle Analytics Cloud (OAC) and a MySQL HeatWave DB instance within Oracle Cloud Infrastructure (OCI).

Deploying OAC

We consider that you already have a DB System up and running in OCI. The first step is then to deploy an Analytics …

You may have noticed that MySQL now supports creating functions (and store procedures) in Javascript using GraalVM.

This new functionality is only available in MySQL Enterprise and MySQL HeatWave.

As a developer, you can also get free access to MySQL Enterprise from Oracle Technology Network (OTN): MySQL Enterprise Download.

I also recommend you look at Øystein’s presentation during the Belgian MySQL Days: [1], [2].

Why use a JS function?

As you may know, UUIDs are increasingly popular and their usage in MySQL is limited to the UUID V1.

I already covered this in the blog post titled …

If you use MySQL Shell for Visual Studio Code, using a bastion host is the easiest method to connect to a MySQL HeatWave DB Instance on OCI.

If you already have a connection setup using a bastion to host, you may experience the same problem as me, MySQL Shell complains about an invalid fingerprint detected:

This error has nothing to do with the fingerprint of your user OCI Key. The problem is related to the key of your bastion host as you can see in the output window:

This happens if you have changed your bastion host for example.

To resolve the problem, remove the current ssh host key for the bastion host stored in your know_hosts:

$ ssh-keygen -R "host.bastion.us-ashburn-1.oci.oraclecloud.com"

Use the name of your bastion host of course.

When done, it’s already fixed, you can connect back to your MySQL HeatWave DB Instance using MySQL Shell …
