AWS – Build your own Oracle Linux 7 AMI in the Cloud
I always like to know what is installed in the servers that I need to use for databases or Weblogic installs. Whether it is in the Oracle Cloud or in any other Cloud. One way to know is to build your own image that will be used to start your […]
Oracle Compute Cloud – Uploading My Image – Part one
Recently (October 2016) I had the opportunity to attend an Oracle Compute Cloud workshop that was very interesting. As a side effect I got access to the Cloud for a month thus I could experiment with the Cloud outside the workshop as well. I’ve had some experience with Amazon EC2 […]
RAC and preventing Active Data Guard: My experiences
When you happen to have a customer that want’s to use Data Guard on Oracle RAC without a license for Active Data Guard then you might want to read this post. You probably have searched on the internet (just like I did) and already found this nice post from Uwe: http://uhesse.com/2013/10/01/parameter-to-prevent-license-violation-with-active-data-guard/ […]
SQL*Plus / SQL*Net Dead Connection Detection
Recently I came across the situation where I knew for a fact that my sessions to the database were dead because I pulled the power plug out of my application server for a failover test. But the sessions stayed visible in the database and kept their locks therefore the failover failed. Now how […]

In my recent post I already mentioned it a little bit: Integrating your manual Data Guard Broker configuration in OEM Cloud Control can become a sort of climbing a Mountain. And it doesn’t have to be. But first a short description of the situation. I have a working Data Guard broker […]
How to add your Standby Cluster Database to Cloud Control
The last few months I’ve been working with Oracle Data Guard, reading lots of manuals and (parts of) books, to make smart decisions and get a solid foundation. I consider myself part of the people who like to work with the command line. That way you really get to understand what […]
You consolidated your applications in one database, but now one application needs recovery…
Imagine this: You have consolidated you applications into one database (version 10gR2). You take a full backup every Tuesday and Thursday evening and an archivelog backup every few hours. These backups go to an NFS share, and not straight to tape. Everything is running fine until one day a new […]

My First Steps with RAC One Node 11gR2 (11.2.0.2)
I’ve been using RAC (10gR2) for years now and I was wondering how RAC One Node differs from RAC. That’s why I used a few ‘old’ RAC servers that we had ‘laying’ around to install a RAC One Node Cluster. I also used that cluster to get some hands on […]
10gR2 RAC service failover and ORA-12545
A few years ago I was lucky to be able to start working for a client that has Oracle RAC clusters. There we encountered lot’s of interesting issues, and one of them was that several client applications couldn’t seem to connect to the RAC cluster whenever a service was failed […]
Remote printing to Windows printservers from Solaris
Recently I found myself in the situation that we had gotten an incident about some application that couldn’t print anymore to the printers it was printing before. This was a big issue and we had to work on it immediately, since it had to be fixed yesterday. Sounds familiar? Apparently […]

Hotsos 2008, Day one
Hotsos 2008, first day of the symposium Today I had to make some difficult choices: There are too many presentation to see or just not enough me to go around. Finally I choose to attend: The Keynote by Cary Millsap Semantic Query Optimization by Toon Koppelaars Leveraging Oracle’s Extended SQL […]
Hotsos 2008, here we come…
It was supposed to happen in 2007, but due to some private issues I never made it to Hotsos that year. I have been wanting to attend since several years but was not succesfull in talking my (former) employer(s) into it. Actually the lack of growth in a professional way […]
