5 mistakes you should avoid with Oracle Database Appliance

By | Database Administration & Monitoring | One Comment

Introduction It has been 5 years I’m working on ODA and I now have a quite good overview of the pros and the cons of such a solution. On one hand, ODA can greatly streamline your Oracle Database environment if you understand the purpose of this appliance. On the other hand, ODA can be your nightmare if you’re not using it as it supposed to be used. Let’s discover the common mistakes to avoid from…

Reimaging an old X3-2/X4-2 ODA

By | Database Administration & Monitoring, Oracle | No Comments

Introduction X3-2 and X4-2 ODAs are still very capable pieces of hardware in 2018. With 256GB of RAM and at least 16 cores per node, and with 18TB RAW disk capacity as a standard these appliances are far from obsolete even you probably don’t have any more support on the hardware from Oracle. If you own several ODAs of this kind, hardware support may not really be a problem. If something fails, you can use…

ODA database been stuck in deleting status

By | Database Administration & Monitoring | No Comments

Facing an internal inconsistency in the ODA derby database is very painful (see https://blog.dbi-services.com/oda-lite-what-is-this-odacli-repository/ for more info about the derby database). I have recently faced a case where the database deletion was failing and the database remained then in “Deleting” status.  Connecting directly to the internal derby database and doing some self cleaning is very risky and should be performed at your own and known risk. So, in most of the case, a database inconsistency issue…

Patching ODA lite to 12.2.1.4.0

By | Database Administration & Monitoring, Database management, Oracle | No Comments

Here is how to apply the latest patch for your ODA. As usual the Oracle documentation is not 100% accurate. I applied this patch on 2 ODAs X7-2M previously deployed in 12.2.1.2.0, no intermediate patch was needed. 1) Download the patch The patch number is 28216794. This patch will update the following components:  dcs (odacli), operating system, bios/firmwares, ilom, GI, dbhomes and databases. Download and copy the patch to a temporary folder on the server,…

ODA, network interface and configure-firstnet

By | Database Administration & Monitoring | No Comments

Deploying new ODA X7-2S or 2M, I have been curious how configure-firstnet would interact with the fiber and copper ethernet network interfaces. Reading documentation on the web, I could not clearly understand if it is mandatory to have the ODA connected to the LAN when performing an ODA reimage and/or running the configure-firstnet in additionnal of having ILOM connection. After digging deeper and few tests, I wanted to share my experience in this blog.

How reimaging detects the ODA hardware?

By | Database Administration & Monitoring | No Comments

A long time ago, ODA referred to the only model that existed (nearly). Actually, not so long time ago, as ODA X3, X4 and X5 were released between 2013 and 2015. And it was quite the same hardware. Now there is 3 current models in the X7 range, and they were 4 in the previous generation (X6). ODA is now divided in 2 main lines. High Availability models, understand 2 nodes and a shared storage…

ODA migration challenges: Non-OMF to OMF + 11.2.0.3 to 11.2.0.4

By | Database Administration & Monitoring | One Comment

To do some application and performances tests, I had to copy a database from a third party Linux server to an ODA X7-2M. Looks pretty simple on the paper, but 2 small challenges came into the game. The first was that of course the source database was in Non-OMF while ODA works fully in OMF. The second was that the source database is running 11.2.0.3 which is not supported and cannot be installed on the…

ODA Lite: What is this ‘odacli’ repository?

By | Oracle | One Comment

By Franck Pachot . When ODA Lite was introduced, with ODA X6-2 S/M/L, and now with ODA x7-2 S/M, a new ‘odacli’ was there to manage it. It will probably replace the oakcli for ODA HA as well in the future. One big difference: it uses a repository to record the configuration and the operations. I don’t really like it because when something fails you are blocked. Oracle Support can modify the directory, but they…
