Infrastructure at your Service
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.
Having recently reimaged and patched several ODA in version 19.8 and 19.9, I could see an issue with NTP. During my troubleshooting I could determine the root cause and find appropriate solution. Through this blog I would like to share my experience with you.
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 of my latest ODA project. Before choosing ODAs A serious audit of the current infrastructure…
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: feed up the database with a manual restore or an RMAN duplicate. Create a 12.2…
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. And I’m here to give you my feedback. Disclaimer You’ll need 2 ODAs for building…
ODA 19.9 has just been released for Bare Metal yesterday, and I had the opportunity to already patch a customer production ODA to this latest version. Through this blog I wanted to share my experience on patching an ODA to 19.9 as well as a new tricky skip-orachk option.
Introduction 6 months after the 19.6, the first 19c production release, here comes the 19.9 Oracle Database Appliance patch with major improvements. Will my ODA supports this 19.9 patch? First, the 19.9 release will be the same for all ODAs, as usual. Like 19.6, the oldest ODA compatible with this release will be the X5-2. Don’t expect to install 19c on older models. X4-2 is stuck to 18.8, X3-2 is stuck to 18.5 and V1…
Introduction Oracle Database Appliances rely on ASM to manage disk redundancy. And ASM is brilliant. Compared to RAID, redundancy is managed at the block level. For NORMAL redundancy, which is similar to RAID1, you need at least 2 disks, but it can also work with 3 disks, 4 disks, 5 disks and so on. There is no need for parity at the disk level. HIGH redundancy, which does not exist in RAID technology, is basically…
Introduction Oracle Database Appliances are very popular these days. And not only among new customers for this kind of engineered systems. Almost all customers already using old generation ODAs are renewing their infrastructure by choosing again ODAs, meaning that the solution is good enough and probably better than anything else. But now, public clouds are a real alternative to on-premise servers, and Oracle Cloud Infrastructure is a solid competitor vs Amazon and Azure public clouds….
I have been recently deploying some new ODA X8-2-HA. After reimaging and creating the appliance, I had to patch the ODA. The day after, checking status, I could realize that my node 0 was not working as expected. I did some interesting troubleshooting that I wanted to share hoping it might be helpful for someone.
