New blog article by AMIS: My “Sinatra-Solution” for Error Code 235 of OMSPatcher 13.8.0.2 - and How I resolved it …. My Way 235 … 235 … isn’t it an Interstate in Oklahoma? Is Oracle telling me that I’m now working with only 0.72% of all naturally occurring uranium? Was I testing the maximum speed of a BMW 3series? Or did somehow an Un-locked Control File Transaction (ORA-235) occurred during my OMS-system patch? No. All I did, was testing a patch with OMSPatcher 13.8.0.2 and it failed to lo...

New blog article by AMIS: How to securely access remote content without using a VPN: Use a proxy server accessed through an SSH tunnel - There are numerous occasions that I was limited in my work because of connectivity which could not be trusted. For example; I could not download large installers due to a proxy anti virus tool which manipulated downloads causing files to become corrupted. I needed to visit a website to find a solution to a problem, but the local proxy server found the cont...

New blog article by AMIS: ADF Performance Monitor: Monitoring with Percentiles - What is best metric in performance monitoring – averages or percentiles? Statistically speaking there are many methods to determine just how good of an overall experience your application is providing. Averages are used widely. They are easy to understand and calculate – however they can be misleading. This blog is on percentiles. Percentiles are part of our recent new 7.0 version of the ADF Performance Monitor...

You can find it here: First steps with REST services on ADF Business Components. I will continue my exploration in the world of ADF REST. We are now going to configure the URL and test the new service. After you run your application, you will see the endpoint in your JDeveloper log: The first thing you will probably notice is t...

New blog article by AMIS: Crash recovery of Oracle databases using Commvault - Some time ago I published an article about creating a RMAN backup using Commvault. See: https://technology.amis.nl/2018/03/01/creating-rman-backups-using-commvault/ . In this article I describe how to execute a crash recovery using Commvault. You need to do a crash recovery when you lost all your datafiles, redolog files, control files and spfile. For example when all the harddisks on which the oracle database fi...

New blog article by AMIS: Oracle’s extended support – when is it free of charge - It’s such a simple, basic and old question I got from a colleague: “Do you have to pay for extended support?”.  And if so, how much I have to pay for it. So basic and yet… always have to check again  the waived support, what prices and where to find this information. It’s getting more important for Oracle Database 11g, which is at the end of the ‘waived’ support. What kind of support you actually get in premie...

This way you spend minimal time setting up the skeleton of your application, letting you focus on adding functionality. This is done by combining a few tools. Let’s take a closer look. Should you be interested in the code itself, go ahead and get it here. Tools NPM/Yarn Be sure to install a...

New blog article by AMIS: Oracle Service Bus 12.2.1.1.0: Service Exploring via WebLogic Server MBeans with JMX - In a previous article I talked about an OSBServiceExplorer tool to explore the services (proxy and business) within the OSB via WebLogic Server MBeans with JMX. The code mentioned in that article was based on Oracle Service Bus 11.1.1.7 (11g). In the meantime the OSB world has changed (for example now we can use pipelines) and it was time for me to pick up the old code and get it...

New blog article by AMIS: Running Istio on Oracle Kubernetes Engine–the managed Kubernetes Cloud Service - In a recent post, I introduced the managed Oracle Cloud Service for Kubernetes, the Oracle Kubernetes Engine (OKE): https://technology.amis.nl/2018/05/25/first-steps-with-oracle-kubernetes-engine-the-managed-kubernetes-cloud-service/. A logical next step when working with Kubernetes in somewhat challenging situations, for example with microservice style architectures and deployments, i...
