Introduction Oracle Database Appliance now fully supports virtualization with KVM, and this could be interesting for some of us. If you’re using Enterprise Edition, you probably decreased the number of cores to comply with your licenses. Now you can increase your core configuration with more cores, some being dedicated to your databases, and some for user-managed VMs. Let’s find out…
Introduction Patch 19.13 is now available on ODA. It’s time to test it. What’s new? This version brings October’s PSU to database and grid homes with their bug fixes, as usual. It also brings 21.4 for DB Systems (21c being an innovation release, understand just for testing). Something new that some of us have been waiting for a while, a…
Introduction As virtualization is available for all ODAs now, you could ask yourself if it’s a good idea to use this virtualization or not. Databases can be created as bare metal, but also within a DB System for better isolation. And both can be used on the same ODA. If you’re looking for how to deploy an ODA with KVM…
Introduction Patching an Oracle Database Appliance is sometimes quite tough and you often struggle to solve failures at different steps. Regarding ILOM and BIOS patching errors, a simple workaround is possible. Errors when patching ILOM and/or BIOS This is something I recently had on an ODA X7-2S when trying to apply patch 19.11. Patching of the test server was OK,…
Introduction Beginning with Oracle Database Appliance (ODA) 19.11. the ORACLE_BASE and ORACLE_HOMEs are created on ACFS. That’s good news, because there is much more space on ASM than on the internal disks, i.e. no space issues with /u01 anymore. So how does it work? ORACLE_BASE and ORACLE_HOME on ACFS When installing an ODA from scratch then ORACLE_BASE and ORACLE_HOME are…
Introduction Until now, High-Availability (HA) ODAs could have been deployed either in bare metal or in virtualized mode. Virtualized mode means that instead of installing a classic Linux system on the nodes, an OVM hypervisor (based on Xen) was deployed. This hypervisor had at least one VM, a special one called ODA BASE, holding all the databases and having direct…
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…
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 You can say everything about Oracle infrastructure possibilities but nothing compares to experience based on the realization of real projects. I did quite a lot of ODA projects during the past years (on other platforms too), and I would like to tell you why I trust this solution. And for that, I will tell you the story of one…
Introduction On ODA, you create your databases with odacli create-database. You can create a complete database, and it takes about 10 minutes, and you can also create an instance-only database. It will simply and quickly create a record in the ODA registry, start the instance with a basic pfile, and that’s it. Then you’re supposed to do the next step:…
Introduction I always thought integration of Data Guard was a missing feature on Oracle Database Appliance. For sure, you can configure Data Guard manually as you do on a classic server, but as an appliance, ODA should have proposed an easier way for configuring that. After years of waiting for this feature, it’s now available, and I just tested it.…
