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 published a number of articles, investigating pieces of the puzzle that come together in today’s challenge. After general introductions of the combination of Vagrant and (more...)
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 one running the Docker Engine. Because I am typically using Vagrant to spin up a Docker Host VM and subsequently the Docker Containers inside that (more...)
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 set up the software that the container subsequently will run. It can also be because my development environment management is fully containerized, including management of (more...)
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 to admit defeat: there is no way to access files outside the Docker build context (other than through HTTP download) and there is no way (more...)
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 a Virtual Box Linux VM that provides the Docker engine & infrastructure. Execution of simple Docker files was demonstrated including how to make files from (more...)
Automated environment provisioning and use of virtualization isolate environments is a topic that has become quite important to me – and to many others. From virtual machine technology, such as VMWare, VirtualBox and Oracle VM, to more recently the use of container technology and especially Docker, I am constantly trying to wrap my head around things and find ways of efficiently, smoothly hence automatedly working with environments. Vagrant has been a great tool for me (more...)
Just a quick post, we announced a while ago that we will be bringing Docker to Oracle Solaris - you can read some background and find a link to the press release here.We'll hopefully be talking about developments at this year's Oracle Openworld so maybe I'll see you there.
When using the Android SDK for testing mobile applications (for instance, created with MAF, Mobile Application Framework), you can utilize the GPU for hardware acceleration on the Windows platform. This will greatly improve the performance of the emulator. To be able to use the acceleration, you’ll need to install a separate package called Intel x86 Emulator Accelerator (HAXM installer).
Android SDK Manager
If you’re on the Linux platform, you notice that the Status is “Not (more...)
I was troubleshooting some Windows hangs on my Desktop system running Windows 8 and enabled driver verifier. Today when I tried to start VirtualBox it failed with this error message.
Failed to load VMMR0.r0 (VERR_LDR_MISMATCH_NATIVE)
Most of the online forums were asking to reinstall VirtualBox to fix the issue. But one of the thread mentioned that it was being caused by Windows Driver Verifier. I disabled it, restarted Windows and VirtualBox worked like a (more...)
Virtualbox on my Windows 8.1 stopped running 64bit guests a while ago. I did not track down this problem. Now some months later i tried again and found some confusing things.
BIOS virtualization enabled
Intel Processor Identification Utlility in 8.1: virtualization disabled
BIOS virtualization disabled
Intel Processor Identification Utlility in 8.1: virtualization enabled
With both settings: Virtualbox runs 32bit guests but no 64bit guests.
After some searching, (more...)
Some time ago a vmware server did not recognize any more a data disk. This disk was formatted with vmfs v3
(enter the vmware server via ssh and type mount..). First thing i did, was creating an image of this disk, to play around without any danger of data loss.
There is a good article how to mount vmfs
, but on debian i had to install the package otherosfs.
After i installed this (more...)
Hi All, On February 4, 2014 at 9:30 am PT I will be talking on the next OTN Virtual Developer Day about Oracle VM and Oracle Database. Come and discover the answers for the following questions: Does an Oracle Database perform well on a virtualized environment? What virtualization technology is more stable and […]
Some time ago, I received the request to migrate some Windows 2008 Servers to my Oracle VM farm and after complete the P2V migration the newly create VM would not start. It would crash on boot with blue screen and error: STOP: 0x0000007B (0xXXXXXXXX,0xXXXXXXXX,0×00000000,0×00000000) This issue is related to the storage drivers needed for the guest […]

So one more successful annual conference of All India Oracle Users Group (AIOUG) happened on November 9th and 10th at Hyderabad, India.
Earlier I used to attend Oracle database sessions at AIOUG but this time AIOUG board had done a remarkable job by extending the coverage to Solaris topics. Obviously as (more...)
A while back, I noticed this session in the Open World 2013 content catalog. I didn't think much of it at the time, other than that it had a catchy title. The other day, I downloaded the latest Exadata deployment utility via the OneCommand tool. I noticed something a little (more...)
Some time ago I made a benchmark exercise to compare the performance of an Oracle Database running in a bare metal environment versus a virtualized environment to clear some of the main questions our team and clients in Revera have,…
We will complete our lab by installing the Oracle Database software, create a Pluggable database and take a look in the Oracle Enterprise Manager Database Express. The steps to install and create an Oracle Database 12c are: 1 – Go…
