Java programs as native executables: GraalVM is the answer!

Rosanna Denis 2

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 […]

Regenerate Oracle VM Manager repository database

Ronnie Kalisingh

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> <> <ovmm003.gemeente.local> <AdminServer> <Scheduled Tasks-12> <<anonymous>> […]

How to create a private 10 Gb network on an ODA X5-2

Jaap Poot

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 […]

Network considerations on an ODA X5-2

Jaap Poot

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 […]

Generate Docker Containerized Run Time and Design Time for Oracle StreamExplorer, Event Processor and JDeveloper using Vagrant, Puppet and VirtualBox

Lucas Jellema

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 […]

Vagrant and Docker followed by Puppet to provision complex environments

Lucas Jellema 1

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 […]

SQL*Plus / SQL*Net Dead Connection Detection

Patrick Roozen

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 […]

Configuring a private DNS server on Openfiler for use with Oracle RAC 12C on Virtual Boxes

Job Oprel

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, […]

WebLogic -> FMW Provisioning update

Edwin Biemond

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 […]
