I’m super looking forward to next weeks DevOps Enterprise Summit in San Francisco. You might ask “Why?!” since I’m a database guy and not a DevOps guy. I can understand that reaction.
I don’t know about you, but when I hear the term DevOps I have to roll my eyes and think “oh, the latest greatest tech industry buzzword.” So why would I as a DBA care about DevOps? With DevOps, as with (more...)
In my earlier blog posting I listed the different Oracle Cloud Services. Due to the massive introduction of all cloud based solutions it is difficult to have an overview of all cloud based solutions and their roadmap for launching. I have drafted an overview of these items on the image below and listed the products and links to more information.
Oracle Cloud platform as a Service roadmap
Direct access to Oracle Cloud (more...)
Disclaimer: I’m not posting to make me look better, we’ve all written code that we’re later ashamed of, and I’m no different!
This is some code from a system I was maintaining some time ago. I’ve kept it since then because it illustrates a number of things NOT to do:
(in_password IN VARCHAR2)
-- do NOT copy this code!!! ...
RETURN VARCHAR2 IS
CURSOR cur_rules IS
Microsoft recently released it first preview version of their next desktop operating system, Windows 10. In our business, we have seen many large companies just migrate to Windows 7 and the general consensus seems to be that Windows 8 is a 'consumer' operating system. In other words, it will be a while before you have to think about Windows 10, but it is our
business to be thinking about this now. We have the Windows (more...)
Every once in a while it comes to my attention that edb360 takes several hours to run. What can be done? My advice is to let it run for several hours if possible. In most environment it completes in less that 1 hour, but I have seen cases where it may take 5 or 6. The reason is simple: too many SQL statements to execute. And some of those queries are executed on top of (more...)
I modified the bind variable extraction script that I normally use to make it more helpful to me.
Here was my earlier post with the old script: blog post
Here is my updated script:

set echo on
set linesize 32000
set pagesize 1000
set trimspool on
column NAME format a3
column VALUE_STRING format a17

This article describes how to standardize your JDeveloper Installation as requested in Planning & Getting Started – Team, Skills and Development Environments. It is part of the ADF Architecture Practice lessons and describes the installation with examples for windows.
In this version the Oracle Universal Installer allows the silent installation of JDeveloper. All what you need is the installer file for your platform (e.g. jdev_suite_121300_win64.exe) and a response file. You (more...)
Now that the chaos of Oracle OpenWorld and the craziness of Kscope15 abstract submissions are behind us, it’s time to get into the nitty gritty of where your Enterprise systems are headed. Mobile development plans are at the forefront of everyone’s minds right now, and if it’s not on your agenda then it’s time to get to work!
Your employees are going mobile, is your business ready?
The statistics of mobile adoption are STAGGERING; Gartner says that 40% of the workforce (more...)
This one looks like the real thing ... getting advice to "not skip" the patching process for a whole bunch of things included here.
I'm just saying ...
Just a quick note to point out that the October PSU was just released. The database has a few more vulnerabilities than usual (31), but they are mostly related to Java and the high CVSS score of 9 only applies to people running Oracle on windows. (On other operating systems, the highest score is 6.5.)
I did happen to glance at the announcement on the security blog, and I thought this short (more...)
In the last post in this series I discussed some of the various tasks that need to be performed by the flash translation layer – the layer of abstraction that sits between us and the raw NAND flash on which we desire to store our data. One of those tasks is the infamous garbage collection process (or “GC”) – and in these next couple of posts I’m going to look into GC a little deeper.
Welcome to another episode of my developer interviews. It is my pleasure to introduce Matthias Wessendorf (@mwessendorf
), whom I know since a long time already. We've been working in and around Java EE for quite a while and met again in Red Hat finally.
Matthias is working at Red Hat where he is leading the AeroGear project. Previously, he was the PMC Chair of the Apache MyFaces project. Matthias is a (more...)
In a multitenant environment, a common user is a database user whose identity and password are known in the root and in every existing and future pluggable database (PDB). Common users can connect to the root and perform administrative tasks specific to the root or PDBs. There are two types of common users :
- All Oracle-supplied administrative user accounts, such as SYS and SYSTEM
- User created common users- Their names must start with (more...)
What happens when iPhoto doesn’t export movies? One of two things, you re-install iPhoto and risk losing the movies and photos; or you drop down to the Terminal level and move the files manually before re-installing iPhoto.
Option one is easy, you open iPhoto, choose File from menu, and Export… from the File menu list. When you get to the dialog, change it Kind value to original. If everything is working, you should be (more...)
Log buffer space is a simple, yet frequently misunderstood wait event. The main reason for that is probably its name. It sounds as if it points immediately to the answer: if space in the log buffer is the issue, then increasing it surely should resolve it. Well, unfortunately even though log buffer space is simple, it’s not that simple.
Log buffer is an area in memory (SGA, to be more specific) where (more...)
I'm an Uber user, its a great service outside of cities with decent public transport. But I have been thinking about where they will justify the $17bn valuation and give people a return on that $1.2bn investment. At the same time I've been following the autonomous car pieces with interest and I think there is a pretty clear way this can end, especially as Uber have already said they are going
