AMIS, Data Driven Blog – Oracle & Microsoft Azure
Getting value from IoT, Integration and Data Analytics
I’ve used Vagrant since 2015 in combination with Virtualbox for creating development machines. Recently however I’m experiencing more issues with Virtualbox. For example CPUs getting stuck when assigning multiple CPUs to a VM and issues with auto adjusting the guest resolution when resizing the VM window. These annoyances drove me […]

0 Oracle VM is end-of-life and is, since March 2021, in extended support1. In looking for a replacement hypervisor AMIS has turned to KVM. Oracle itself also uses KVM, albeit its own brand of KVM, OLKVM, in Oracle Cloud and on the new versions of its Oracle Database Appliance. Topped with […]
0 0 Like so many colleagues and fellow developers around the world, the latest Windows Update also messed up my machine’s ability to successfully run Oracle Virtual Box. When running vagrant to provision a VM, I ran into messages such as: Failed to open a session for the virtual machine. Call to […]
0 0 TL;DR: • Using GraalVM Java applications can be compiled into native standalone executables (will be demonstrated). • Native executables of small Java programs startup blazingly fast, use considerably less resources compared to running on JVM and do not even require the JRE or any other kind of runtime apart from […]
0 0 VirtualBox networking is extremely flexible. With this flexibility comes the challenge of making the correct choices. In this blog, the different options are explained and some example use cases are elaborated. Access between guests, host and other members of the network is explained and the required configuration is shown. This […]
0 0 Some quick notes to regenerate a corrupted Oracle VM manager repository database. How did we discover the corruption? The MySQL repository databases was increasing in size, the file “OVM_STATISTIC.ibd” was 62G. We also found the following error messages in the “AdminServer.log” logfile: ####<2018-02-13T07:52:17.339+0100> <Error> <com.oracle.ovm.mgr.task.ArchiveTask> <ovmm003.gemeente.local> <AdminServer> <Scheduled Tasks-12> <<anonymous>> […]
0 0 For the upgrade of Oracle VM Server 3.1.1 to version 3.4.3 we decided to create a new repository and mount this repository to the current Oracle VM environment. After cloning the virtual machines to the new repository we reclaim the repository and can start the virtual machines on the new […]
0 0 Some quick notes to “pin” (or hard partition) a virtual machine to a specific core. Download OVM utils which is found in patch 13602094 (Oracle Support): ORACLE VM 3.0 UTILS RELEASES: 1.0.2, 2.0.1, 2.1.0. When you extract the zip file you will find three zip files for the different Oracle […]
0 0 The topic of quickly creating an Oracle development VM is not new. Several years ago Edwin Biemond and Lucas Jellema have written several blogs about this and have given presentations about the topics at various conferences. You can also download ready made Virtualbox images from Oracle here and specifically for […]
0 0 In this sequel of part one I will show how you can upload your own (Oracle) Linux 7 image in the IAAS Cloud of Oracle. This post will use the lessons learnt by using AWS which I described here. The tools used are: VirtualBox, Oracle Linux 7, Oracle IAAS Documentation […]
0 0 Recently I started working on a brand new HP ZBook 15-G3 with Windows 10 Pro. And I immediately tried to return to the state I had my previous Windows 7 laptop in: Oracle Virtual Box for running most software in virtual machines, using Docker Machine (and Kubernetes) for running some […]
0 0 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 […]
0 0 Sometimes I create a VirtualBox disk for usage in a VM with a certain size. I think it will be enough for what I want to use the VM for. After using the VM for a while, it happens (often) that I need more space than I initially assigned. For […]
0 0 The context is: Windows laptop running Virtual Box. I have received a VM from a colleague that contains an Ubuntu (16.04 LTS ) based environment. The VM runs nicely. However, I do not know how to reach it from my laptop. The web application for example that runs inside, and […]
0 0 A while ago I published an article about the ODA X6-2S and X6-2M, the new entry level machines for small business. And since then Oracle introduced the ODA X6-2L and the successor of de ODA X5-2: ODA X6-2 HA. Quite a line of ODA’s. But when to choose what ODA? […]
0 0 In my previous post Network considerations on an ODA X5-2 I described a solution where I created a private network to optimize network performance between the components running on an Oracle Database Appliance. I am talking about a Virtualized setup in this article, and rebuilding the second pair of public […]
0 0 When you buy an Oracle Database Appliance (ODA) X5-2 off the shelve, you will get a machine with four times 10Gb copper Ethernet (bonded into two interfaces) for public communication and two 40Gb InfiniBand (bonded into one interface) for interconnect communication between the two ODA_BASE’s. You would think that should […]
0 0 Oracle offers a fine machine called the X5-2. Not to be confused with the ODA X5-2, which comes with sophisticated database software. The X5-2 is just bare metal. The X5-2 is a 1HE 2 socket Intel machine with limited configuration options in terms of processor speed, number of cores and […]
0 0 The objective of this article: prepare an environment for experimenting with Oracle StreamExplorer using two Docker containers inside a Linux VM running on my Windows laptop. And with the smallest number of manual steps possible – as to make the environment provisioning process highly repeatable. In recent weeks, I have […]
0 0 I came across a simple Google Chrome Addon called Simple Docker GUI. It provide a GUI that allows for easy insight in and some management of Docker containers and images. Because the tool connects to the (remote) Docker API across HTTP, it can used on a different machine than the […]
0 0 Although perhaps not a common occurrence, I would still like to be able to sometimes run GUI applications inside a Docker container. This may be required because an installer does not provide a silent option and has a GUI wizard I need to click my way through in order to […]
0 0 The Docker container build process has some limitations. The Docker file can quickly become unwieldy. Besides, by and large the Docker file has us execution fairly low level instructions – somewhat against the trend of using declarations rather than scripts to specify what environments should look like. Additionally, I have […]
0 0 This article is a continuation of the introduction to the combination of Vagrant and Docker that I started here: First steps with provisioning of Docker containers using Vagrant as provider. These first steps include how you can leverage Vagrant to create and manage a simple Docker container as well as […]
0 0 Note: the next set of (more advanced) steps with Vagrant and Docker are discussed in this article: Vagrant and Docker – Next and Advanced steps with folders, ports, volumes, linking and more. Automated environment provisioning and use of virtualization isolate environments is a topic that has become quite important to […]
0 0 Lately several people asked me how they should go about with upgrading their OVM 3.2.x environment to 3.3.x They have the backend repository running on an Oracle Database, which is no longer supported. In release 3.3, only MySQL is supported as a backend repository database. They were wondering how the […]
0 0 Recently I found myself in the unique position of having access to the beta version of the Oracle Cloud to get a glimpse at the future as Oracle sees it. This blog describes my personal experience and does not necessarily reflect Oracle’s point of view. That said, the cooperation with […]
0 0 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 […]
0 0 When Oracle Exalogic is delivered in you data center and you implemented Exalogic as a virtual platform, the Exalogic Guest Base Template (EGBT) is based on Oracle Linux 5.8. On Exalogic you can update the template to Oracle Linux 5.10. As of 21 october the new Exalogic base template is […]

0 0 Outline This post shows you how to setup an Oracle 11g database VM with the use of Vagrant and Puppet in straightforward steps. Anybody can execute this without knowledge of the internal workings of the products at hand. Even my manager, who isn’t known to be very skillful in the […]
0 0 This post is intended to be a dummy guide, best practices, or whatever you call it… about setting up a network while working with virtual boxes on a desk- or laptop. I was setting up a virtual box environment with several Virtual Boxes on my laptop, and as I’m not […]
0 0 To build an Oracle 12C RAC database – on Virtual Boxes – there’s at least shared storage needed for ASM, and a DNS-server for the SCAN-addresses. Several methods can be used for this, but for the storage in my private project I chose Openfiler, an open source management storage tool, […]
0 0 During the last few months, I have been asked a couple of times to assist in solving problems with crashing Virtual Machines in Oracle VM environments. Failing disk checks on normal filesystems, read-only filesystems. * Fsck could not correct all errors, manual repair needed [ !! ] Give root password […]

0 0 The last few weeks I was busy re-writing pf my puppet WLS module so it fully supports the power of Puppet 3 (thanks for more than 4000 downloads on puppet forge) . With Puppet 3 we now can use Hiera, Iterations and Lambdas expression. This does not sound like a big […]
0 0 Already a year has passed since I wrote about WebLogic and Fusion Middleware provisioning with Puppet. In this year provisioning got a great boost with the popularity of DevOps and provisioning tools like Puppet, Chef or in combination with Vagrant & Oracle VirtualBox. Provisioning without tooling can be hard for companies when they […]
0 0 I have come across customers running their Virtual Machines (VM) on Oracle VM 2.x wanting to migrate them to Oracle VM 3.x Most of the time the engineers think the migration to 3.x is a lot of work. I have seen situations where they installed fresh new VM’s on Oracle […]
