Infrastructure at your Service
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 to life. As a consequence, Data Guard or Dbvisit Standby, depending on which edition you’re…
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, …). As a consequence, do not sell used storage devices. Main reason to follow this advice…
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 of that, for sure if you need them. And you can decide later to use…
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 / /u01 and /opt filesystems. Below the state of our filesystems [[email protected] Downloads]# df -h /…
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 example) the use of ACFS filesystems is mandatory As I already told you, it’s more…
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 older models. X4-2 is stuck to 18.8, X3-2 is stuck to 18.5 and V1 is…
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 listeners: odacli -h | grep listener nothing! The wrong way to configure a listener One…
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 using these old machines, you should know that there is a lot of differences compared…
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 but I think it is not compatible with the latest odacli. However, for a long…
