DBAs are a wealth of knowledge!

Fifteen years ago, in 2005, I remember I read the following speculation about the DBA profession: Oracle 2020 – a Glimpse Into the Future of Database Management. I was curious what would be true 15 years later. Just have a look at some of the predictions:

– 2018: Oracle 14m provides inter-instance sharing of RAM resources. All Oracle instances become self-managing.
– 2019: The first 128-bit processors are introduced.
– 2020: Oracle 16ss introduces solid-state, non-disk database management.

Looking even further we read: “Changing Role of the Oracle DBA in 2020: But the sad reality of server consolidation was that thousands of mediocre Oracle DBAs lost their jobs to this trend. The best DBAs continued to find work, but DBAs who were used for the repetitive tasks of installing upgrades on hundreds of small servers were displaced.” And further: “Inside Oracle 2020: The world of Oracle management is totally different today than it was back in 2004. We no longer have to worry about applying patches to Oracle software, all tuning is fully automated and hundreds of Oracle instances all reside within a single company-wide server.” ADB rings a bell?

Four years ago, another forecast article called The 2020 DBA: A Look Into the Future appeared in dzone.com predicting that despite the evolving role of the DBAs, DevOps has actually made database administrators more relevant than ever before.

True, as the DBA profession is still among the Top 10 jobs in Technology. DBA is #4 in Best Technology Jobs, #15 in Best STEM Jobs and #30 in 100 Best Jobs.

Now, going back to the title of this blog post. Jeff Smith’s, Russ Lowenthal’s and Chris Saxon’s Oracle DBA 2020 Data Masterclasses are something I recommend now to every DBA. Jeff raised an important topic but let us take a step back.

Last month (September 2020), FlashDBA discussed the Evolution of the DBA from 1.0 through 2.0 until 3.0:

DBA 1.0: The (Good) Old Days – clearly the old days are over. Regardless if they were good or bad is a memory-lane discussion.

DBA 2.0: The IT Generalist – I remember when saw this paper for the first time about 10-11 years ago: Oracle DBA 2.0. ASM, Direct NFS, Clusterware, VMware, Flash, Linux. The DBA had to learn OS, Storage and Network administration. With Exadata, I even heard the term DBA 2.1

DBA 3.0: The Cloud DevOps DBA – new game, rather new set! “A DBA building a database in the public cloud is making decisions which have a direct affect on the (quite possibly massive) monthly bill from AWS/Azure/GCP/OCI”.

Checking the Database Management Predictions from 2019, we can see they now we are close to:

DBA 4.0: Autonomous DBA – more attention on data management, data security, data architecture, machine learning, devops:

“Oracle Autonomous Database can quickly provision, resize, and relocate databases with little human interaction. However, as more database provisioning tasks are automated, DBAs will still need to classify the data.” – Michelle Malcher

“CEOs will force DBAs to step into more-important roles—such as data architects, data managers, and chief data offcers—as a company’s data and machine learning algorithms become important drivers of the stock price.” — Rich Niemiec

“Oracle Enterprise Manager Cloud and other third-party tools, in conjunction with Oracle Multitenant will make managing large numbers of databases easier. DBAs will be able to manage 10 times or more databases after consolidation with Oracle Multitenant.” — Anuj Mohan

“DBAs need to understand that there is a true sea change afoot, and there’s no way to stop these market forces. Hopefully, we’ll all be able to embrace this tidal wave and avoid being caught up in the undertow.” — Jim Czuprynski

I believe the adoption of a hybrid infrastructure is inevitable, and the new skills needed (such as cloud set-up, configuration, and monitoring) are mostly cloud-related. DBAs will need to be able to assess the databases and define what they are best suited for. Replication of data and databases will become more complex in hybrid environments—especially when different clouds are involved.

That is coming in few years at most (when most companies will adopt multi-cloud) and call the profession DBA 5.0 if you prefer or just DBA. Every decade has its challenges for IT professionals. Challenges are becoming more complex and DBAs are often on the front line with every new fashionable IT concept. And we can quote now Larry Ellison who said that the computer industry is the only industry that is more fashion-driven than women’s fashion.

Here are finally few additional recent articles on the topic of the future of the DBA profession (if interested to read more on the topic):
