Introduction Building an Oracle infrastructure today without thinking about a Disaster Recovery solution (DR) is quite rare. This became obvious that a backup or a dump will not help if you do not know where to restore or import once your production server is down. And restoring a backup is definitely not the fastest way to bring back your database…
TL;DR If hardware stays inside your data center, it’s ok to secure erase storage devices. If it leaves your data center (decommission, move to another location), it’s best to physically destroy (shredder) it. Storage devices are not only hard drives, solid state drives, but also the ones holding data temporarily like memory modules (RAM) and CPUs (containing caches, register, …).…
Introduction Starting from version 19.11 of the Oracle Database Appliance software bundle, OLVM will definitely replace OVM server as virtualization engine. This change has quite a big impact as there will be no more virtualized specific deployment. Bare metal will come as a standard for all ODAs, and creating VMs for applications, or even databases, will be possible on top…
In this blog I am describing the steps to patch an ODA HA from the version 19.8 to version 19.10. The patching was done with a customer. Thanks to Pierre. The name of the servers were changed The ODA is an X8-HA with following nodes -server-aa -server-ab Before starting the patches, be sure that you have enough space on /…
Introduction Modern Oracle Database Appliances still support 11gR2, but there are several drawbacks using this old version: if you want/need support for your databases, you should pay for Market Driven Support (11gR2 is even no more under extended support – it ended at the end of 2020) some ODA features will not work with 11gR2 (odacli Data Guard feature for…
Introduction 4 months after the 19.9, here comes the 19.10 version of the Oracle Database Appliance patch. Let’s have a look at what’s new. Will my ODA supports this 19.10 patch? The 19.10 release will be the same for all ODAs, as usual. The oldest ODA compatible with this release is the X5-2. Don’t expect to install this version on…
Introduction Oracle Database Appliance has quite a lot of nice features, but when looking into the documentation, at least one thing is missing. How to configure multiple listeners? Odacli apparently doesn’t know what’s a listener. Let’s find out how to add new ones. odacli Everything should be done using odacli on ODA, but unfortunately odacli has no commands for configuring…
Introduction ODA started to become popular with X3-2 and X4-2 in 2013/2014. These 2 ODAs were very similar. The X5-2 from 2015 was different with 3.5 inches disks instead of 2.5 inches and additional SSDs for small databases (FLASH diskgroup). All these 3 ODAs were running 11gR2 and 12cR1 databases and were managed by the oakcli binary. If you’re still…
By Franck Pachot . You want to learn and practice your ODA command line and GUI without having an ODA at home? It should be possible to run the ODA image on VirtualBox but that’s probably a hard work as it is tied to the hardware. About the configuration, you can run the Oracle Appliance Manager Configurator on your laptop…
Introduction One of the advantage of Oracle Database Appliance is its fast deployment. Most often, the initial setup of a lite ODA (with a reimaging) only takes half a day, from unboxing until a first test database is available. Trust me, it’s hard to do better. For some reason, for example if you need to patch to the latest release…
I recently needed to configure bonding between 2 network cards on a customer side and I wanted trough this blog to share my findings and how I built it showing some traces. I will also do a short comparison of what is possible or not on the ODA. Why should I use bonding? Bonding is a technology which will allow…
