A more secure connection to a pdb with the Oracle Wallet

A more secure connection to a pdb with the Oracle Wallet

Wallets are cool! Since 9i oracle is pushing us towards services for connecting to a database. Since pdb’s have arrived, you get less and less choice to connect without a service. Recently I discovered passwords stored in environment variables in order to connect to the pdb. A short talk to the author of the script learned me that he just wants to connect to a pdb, so I offered the solution to store the password in the oracle wallet. Here is how…

Aws s3 outage

Aws s3 outage

Today our aws friends suffered from an outage. This raises some questions.  Suppose your entire organization is built on cloud products. All of them are closely related. This means a total outage for the organization.  What about costs? Personally I am not an aws user, but would this outage be like “sorry dear customer, but you’re going to pay even we had this unplanned outage”. If you’re mission critical, let’s say you’re end users are depending on it. Would it…

Why the sun shines for Oracle and it’s Cloudy for others

Why the sun shines for Oracle and it’s Cloudy for others

First of all, I ‘d like to mention that this draft has been put back from schedule several times over and over again. Asking myself the question, should I really do this? But then again … This is a blog, a very personal humble opinion and you should not agree with me, I can be wrong, I can be right. The truth is probably in between. So, the title “Why the sun shines for Oracle and it’s cloudy for others”,…

A basic overview of the command. If you log on to the cells as root, it…

A warm welcome to exadata SL6-2

A warm welcome to exadata SL6-2

Last years Oracle Openworld, uncle Larry announced the sparc based exadata SL6-2, so this means that we have to give the sparc chips a warm welcome to the Exadata family. During the conference I wrote 2 blogposts. You can find them here and here. To recap, a little picture of the new one in the family: Nowadays, we’re used to the big X for the exadata’s. This is for the x86 infrastructure they are running on. So SL stands for “Sparc…

The first performance related impressions of the new ODA X6-2M

The first performance related impressions of the new ODA X6-2M

New toys are always fun! When Oracle announced their “Small” ODA’s in the X6-2 generation, we were excited to test them. We were not the only ones, so it took a while before getting one, but the first week of january, it was playtime. An ODA X6-2M was delivered to our demoroom and testing could begin. Normally I would start a blog post by “how to install” it. Actually this is very simple and very well documented. If you want me to…

ORACLE DB IN THE AZURE CLOUD – PT2

ORACLE DB IN THE AZURE CLOUD – PT2

During the BI in the cloud project, one of the aspects we had to test is the network. Here is how we did it to figure out how the network performs and most of all, is it stable? One of the most important things in a cloud environment is the network. It connects devices to eachother and makes it possible to have communication between devices. Sounds obvious, right? Some tests we have done, were relying very heavily on the network, such…

Oracle DB in the Azure cloud – Pt1

Oracle DB in the Azure cloud – Pt1

A few months ago (about october) ago we were contacted with the simple question: Can you run an oracle database in the cloud, the Azure cloud. Well … it depends. The little detail was, that the database is about 34TB and there are a few other multi TB databases AND there are a lot of copies of them. And … the final decision for go live is … end of 2016.  Well, we accepted the challenge. The deadline was strict, so that’s also…

Documentation bug in ovm for Exadata

Documentation bug in ovm for Exadata

A while ago a customer gave me a heads up about the “bug” concerning the default passwords for root and celladmin. I was thinking a bit further and I wondered if the “documentation bug” I found while adding a new OVM in the virtualised exadata is solved. The official documentation can be found here . Then “Managing Oracle VM Domains on Oracle Exadata Database Machine” and then “Creating Oracle RAC VM Clusters” brings you to the point I want to warn you…
