Why Automation Matters : Patching and Upgrading

As I said in a recent post, you know you are meant to, but you don’t. Why not?

The reasons will vary a little depending on the tech you are using, but I’ll divide this answer into two specific parts. The patch/upgrade process itself and testing.

The Patch/Upgrade Process

I’ve lived through the bad old days of Oracle patching and upgrades and it was pretty horrific. In comparison things are a lot better these days, (more...)

Implementing API Platform Book extract

An extract of our new book Implementing API Platform has been made available by the publishers Packt here. Of course you could enjoy all the content by buying the book directly from Packt (go here) or from book retails such as Amazon (here).

The Death of TLS 1.0 and 1.1 : Should You Panic?

There have been some stories recently about the death/deprecation of TLS 1.0 and 1.1. They follow a similar format to those of a few years ago about SSLv3. The obvious question is, should you panic? The answer is, as always, it depends!

Web Apps

For commercial web apps you are hopefully doing the right thing and using a layered approach to your architecture. User traffic hits a load balancer that does the SSL (more...)

Oracle Podcasts – Beer & Pizza

We have been fortunate enough to participate an ArchDev podcast about meetups – https://blogs.oracle.com/developers/pizza%2c-beer%2c-and-dev-expertise-at-your-local-meet-up

The podcast talks about the differences between the meet-ups and events such as conferences, what we try to get out of a meetup and the effort put into arranging them.

Why Automation Matters : Reliability and Confidence

In my previous post on this subject I mentioned the potential for human error in manual processes. This leads nicely into the subject of this post about reliability and confidence…

I’ve been presenting at conferences for over a decade. Right from the start I included live demos in those talks. For a couple of years I avoided them to make my life simpler, but I’ve moved back to them again as I feel in some (more...)

Why Automation Matters : Lost Time

Sorry for stating what I hope is the obvious, but automation matters. It’s mattered for a long time, but the constant mention of Cloud and DevOps over the last few years has thrown even more emphasis on automation.

If you are not sure why automation matters, I would just like to give you an example of the bad old days, which might be the current time for some who are still doing everything manually, with (more...)

Oracle Code – Capgemini Blog

I have a new blog post over on the Capgemini site – https://www.capgemini.com/2018/06/oracle-code-london/ talks about the way Oracle has changed its engagement towards developers and the Oracle Code London event that I presented at – first mentioned at Oracle Code London – Presentation & Periscope Interview

 

Creating an Oracle Database Vagrant box

Oracle recently launched a new GitHub repository for providing people with Oracle software inside Vagrant boxes. If you have ever setup an Oracle database inside a VirtualBox VM, whether it is as your sandbox environment, to explore Oracle database, or to use it as a full-on development environment, things have just gotten a lot easier … Continue reading "Creating an Oracle Database Vagrant box"

Oracle Code London – Periscope Interview

Whilst in London Wednesday to present Microservices in a Monolith World at the Oracle Code London,  I also participated in an interview streamed via Periscope.  The interview can be seen at https://www.pscp.tv/w/1jMKgqBrwYyJL 

 

Documenting APIs on the Oracle API Platform

The last week or two I have been working on a new API Platform utility to add to my existing tools (see here). This tool addresses the question of generating documentation.  Much as been said about API documentation and the quality of it, check out these articles :

If you look at these articles and others, there are some common themes, which are:

  • Document the URI / payload
  • Describe (more...)

Creating an Oracle Rest Data Services Docker image

Oracle has added Oracle Rest Data Services (ORDS) to the Docker build files family on GitHub, which means that you can now easily dockerize ORDS. If you don’t know yet what ORDS is, it’s a free technology from Oracle that allows you to REST-enable your Oracle databases. More specifically, with ORDS you can just fire … Continue reading "Creating an Oracle Rest Data Services Docker image"

UKOUG Tech 18 Conference

The call for papers for the U.K. Oracle User Group’s 2018 Conference in December is out. The committee are looking for papers across not just core Oracle technologies like the database and SOA Suite but newer technologies such as Event Hub. With Oracle’s engagement with developers and the commitment to open source the UKOUG has moved to engage with these users as well. So the committee will welcome submissions about open source tech that (more...)

Lessons in Oracle Cloud Password Management

Oracle Cloud is growing and maturing at a tremendous rate if the breadth of PaaS capabilities is any indication.  However, there are a few gotchas out there, that can cause some headaches if they get you. These typically relate to processes that impact across different functional areas. A common middleware stack (API CS, SOA CS, OIC etc) will look something like the following:

cloudPassword

As the diagram shows when you build the cloud services, the (more...)

Enabling SFTP-only access on Linux

Recently I had the need to share a zip file with a bunch of people that was big enough not to fit into email anymore. So I wanted to get it onto my server so that folks could grab it via SFTP from there. SFTP is setup by default on my Linux environment, so them … Continue reading "Enabling SFTP-only access on Linux"

Data Warrior #HappyDance! Guess who joined @Snowflakedb

It going to be a big day at Snowflake. Two of my good friends are joining my team.

Deploying a Kubernetes cluster with Vagrant on Virtual Box

Oracle has just included Kubernetes support for its VirtualBox Vagrant GitHub repository. With that it’s now easier than ever to get a Kubernetes cluster up and running inside VMs. If you have not come across Vagrant yet, it’s a great tool by HashiCorp for “Development Environments Made Easy“. tl;dr Install VirtualBox Install Vagrant Clone the GitHub … Continue reading "Deploying a Kubernetes cluster with Vagrant on Virtual Box"

Manually installing a Maven artifact in your local repository

I find myself once again in the situation that I have to install the Oracle JDBC driver into my local Maven repository. Usually this is easily accomplished via mvn install:install-file -Dfile=<path-to-file> -DgroupId=<group-id> -DartifactId=<artifact-id> -Dversion=<version> -Dpackaging=<packaging>, see Guide to installing 3rd party JARs for more details on that. However, this time I was thinking to go the … Continue reading "Manually installing a Maven artifact in your local repository"

Managing API Policy Versioning in Oracle API Platform

Oracle’s API Platform (API-P) product avoids the use of external configuration management. If you want to better understand why, then checkout our forthcoming book as it goes into detail about why this is the case (it can be pre-release version of the book can be obtained here). In a previous blog I wrote about and illustrated the use of the API-P’s own APIs so that it was possible to see what API iterations had (more...)

Tracing Executions in an API Environment

As APIs become more pervasive within our solutions we see the arrival of not just design and cataloging tools such as Apiary, Apigee and others but also the arrival of gateways. The gateways provide execution of operations including validation, accounting (moneytization), routing, and other controls such as throttled checks that would often not occur until the first contact with a service bus. For example initial routing based on the API call, fine grained authentication (more...)

How to create small Docker images

When it comes to space efficiency Docker still isn’t quite as good as it could be. The layered filesystem used by Docker sometimes occupies more space than is really necessary. Over time, a couple of enhancements have made their way into Docker to allow the build of more space efficient images. The ADD instruction for example … Continue reading "How to create small Docker images"
