Oracle DB Upgrade 12.1 auf 12.2

Ich bin gerade dabei einige Datenbanken von 12.1 -> 12.2 upzugraden. Dazu setzte ich den DBUA ein und bin sehr positiv überrascht. Viele Checks werden im Dialog abfragt und diese werden dann während des Upgrade Prozess umgesetzt. Der Upgrade läuft reibungslos durch auch wie in meinem Fall auf RAC Datenbanken.

Möchte man den Pre-Upgrade vorab durchführen und dies per Skript steuern, dann kann man auf Metalink dazu ein Skript herunterladen. Dieses Skript sammelt (more...)

Introducing SQLdb360: merging eDB360 and SQLd360, while rising the bar to community engagement

Today, we are very happy to release SQLdb360, a new tool that merges together eDB360 and SQLd360, under a single package.

Tools eDB360 and SQLd360 can still be used independently, but now there is only one package to download and keep updated. All the new features and updates to both tools are now in that one package.

The biggest change that comes with SQLdb360 is the kind invitation to everyone interested to contribute (more...)

User Research at the Forefront of Technology

Editor’s note: For posterity’s sake, I’m reposting some content that we created during our time at Oracle. These statements and views are those of the author and do not reflect those of Oracle’s current user experience organization.

What do you do when you don’t have users yet?

Oracle’s approach to researching emerging technologies isn’t really about the technology; it’s about the users: observing, listening, empathizing, and learning about our users and what matters to them.

exachk 18.2.0_20180518 released

Oracle released the new Version of exachk. The version is shown as 18.2.0_2018052018 so far so good. The next sentence in the Note is: „What’s new in exachk 12.2.0.1.4 may be found in the „What’s New in 12.2.0.1.4″ section of the User’s Guide available here..“

The new Release model from Oracle is really confusing. From my point of view it makes no sense that you download (more...)

Export – Import Business, Again


"At first it was difficult to tell just what had changed—it all looked the same
and it all smelled the same—but, for some reason, nothing sounded the same."
-- Norton Juster, The Phantom Tollbooth

Doing things just because “they’ve always been done that way” may not be the best reason to stick with old and accepted processes and utilities. Oracle has changed significantly over the years and those improvements shouldn’t be ignored simply because (more...)

Playing with ADWC (Autonomous Data Warehouse Cloud Service)

Oracle has launched Oracle 18c and the Autonomous Data Warehouse Cloud Service (ADWC). Many people call the Oracle 18c as the Autonomous database, and this is a huge mistake! Oracle 18c (that is in reality Oracle 12.2.0.2) is not an

A week of PostgreSQL

One of the attractive things of my job is this… Just a bit more often than every now and then, you get the opportunity to get out and meet people to talk about Postgres. I don’t mean the kind of talk I do every day, which has more of a commercial touch to it. – Don’t get me wrong, that is very important too! – But I mean, really talk about PostgreSQL, be part of (more...)

Epilogue

The AppsLab experiment ended this week as nearly all of us were laid off from Oracle.

Noel and I decided to keep this blog running, both as a historical resume of sorts and as a way for all of us who worked in ‘Lab over the years to share our ongoing adventures and talk about technology.

We had a good run, thanks to executive leaders like Paul and Jeremy, and I will always remember the (more...)

Oracle and More…

It has been over a year I wrote my last blog post. I would admit I was being lazy to write, but the good part is not anymore !!

I plan to take out some time and write at least 2 blogs every month and share my learning with the community and to learn from the community.

With the current pace of change in technology, it very important to keep up with it, though sometimes it (more...)
