Oracle Apex on Autonomous with custom ORDS

In one of my recent blogs I’ve described how you can use Nginx as a reverse proxy to assign your custom domain name to the Oracle Apex on Autonomous database. But you still use the default ORDS managed by Oracle. What if you want to change some ORDS parameters? For example you might decide to change the “low” type of connection to “high” or “medium”. In this post I will describe how to install your custom ORDS to work with Autonomous databases in standalone mode, using only Tomcat and Apache http server with Tomcat as the frontend.

Oracle Apex on ATP with custom domain

If you have an Apex app on top of your Oracle Autonomous database you have the application URL like https://m5c5hpup7eqqydh-glebatp01.adb.us-ashburn-1.oraclecloudapps.com/ords/r/covid/covid-ontario/covid_ontario. This is already better than it used to be before and have a friendly path in the URL but what if you want to use your own domain address and custom URL? This blog is about how to set it up using reverse proxy. The way with a custom ORDS is a subject for another post.

So, you have your own domain registered in DNS, for example apex.gleb.ca and an application like I’ve listed above. What you want to do is to make the application URL as https://www.apex.gleb.ca/covid/ . What we are going to use is a virtual machine with a Nginx web server serving as a reverse proxy to your Apex application created on the Oracle Autonomous database.

Oracle Database Service for Azure

Recently Oracle and Microsoft announced availability of their new service – Oracle Database Service for Azure. It raises the level of integration and interoperability between Oracle Cloud and Microsoft Azure. With the new service Microsoft’s customers are able to create and manage Oracle databases created in Oracle cloud and use them for applications located in Azure. That sounds great and moves us one step closer to a real multi-cloud environment. Before proceeding, let me clarify what I mean as the “real” multi-cloud. I mean an environment where different pieces of the same IT service are located in different clouds working as a whole.

MongoDB on Oracle Autonomous

Earlier this year Oracle announced support for MongoDB API on the Oracle Autonomous database family. It has been recognized as a huge milestone by Forbes and multiple other analysts, technical and market experts. In my opinion it was logical and fully predicted one more step to the main idea of “Converged Database”. I didn’t coin that term – Oracle was using it for two or three years as of now. The main idea is to create a fully managed database platform supporting the most of APIs and interfaces and put the data together under the Oracle Autonomous Database umbrella. Here I will try to look inside and understand what it is, how it works, what is supported and what is not.

Data Pump Export on Oracle Autonomous

The blog was supposed to be a small how-to but it has grown to a bigger one and hopefully might help to avoid some minor problems while exporting data from an Autonomous Database (ADB) in Oracle Cloud (OCI). It is about exporting data to the Oracle DataPump format to move data to another database or as a logical “backup”.

Oracle documentation provides sufficient information but I find it more and more difficult to navigate considering the number of options and flavours for Oracle databases. There are some new ways and tools around Oracle OCI ATP which can help in some cases. If you want you can jump directly to the end to read the summary.

Blog on Oracle OCI ARM free tier.

This blog was primarily driven by questions from my peers and colleagues who wondered where my blog was hosted and how it was created. It might help to move from a hosting platform to your own website and where to start.

Like most bloggers I started my blog using one of the hosting platforms but soon after found some limitations in choosing appearance, plugins and was a bit annoyed by some commercial banners on my page. After a while I decided to move to my own site. I bought a domain name for myself and created my own environment using the WordPress software on a cloud VM. It didn’t cost me too much but it was not entirely for free. When Oracle introduced some additions to the always free set of resources. I decided to give it a try and move my blog entirely to the OCI free tier.

For those who would like to skip the reading and try, I have a set of Terraform scripts on GitHub. They haven’t been updated lately and use not the latest versions but can be a good place to start.

Moving Oracle database to the cloud. 12.2 standalone to 19C RAC PDB.

I see more and more Oracle databases are moving to the public cloud or to a hybrid cloud solution. Depending on the platform, size and used options it could be a different path but the general approach boils down to three main options – Oracle RMAN backup and restore, Oracle Data Guard or Oracle Data Pump with or without transportable tablespaces. Here I want to share our approach for migration from 12.2 standalone database to 19c RAC container as PDB in the Oracle Cloud Infrastructure (OCI).

Linux LVM for Oracle Database on OCI

Oracle Database as a service (DBCS) on Oracle Cloud Infrastructure (OCI) had been traditionally built based on Oracle Grid Infrastructure with ASM as the main storage layer for the database, however Oracle recently has started to offer a Linux LVM as the storage alternative. Which option is the better alternative? Let’s review some of the differences between the two options.

Copy files to Oracle OCI cloud object storage from command line.

This blog post is bit longer than usual but I wanted to cover at least three options to upload files to the Oracle OCI object storage. If you need to just upload one file you can stop reading after the first option since it covers probably most of needs to upload a single file. But if you want a bit more it makes sense to check other options too. Continue reading “Copy files to Oracle OCI cloud object storage from command line.”

Oracle Cloud Infrastructure multi-factor authentication

For some time we didn’t have a multi-factor authentication in the Oracle cloud and those short-lived numeric codes were one of the best way to reinforce your protection and prevent a bad actor to break your credentials. It is not 100% protection but it is well better than a username and a password. Just recently I read in the Oracle Infrastructure cloud blog about new native multi-factor authentication for Identity and Access Management (IAM) system on Oracle Cloud Infrastructure (OCI). Of course, I went directly to my account and started to test it. Continue reading “Oracle Cloud Infrastructure multi-factor authentication”
