By Mouhamadou Diaw The ODA X4 is still in use for some customers. The last time I was asked to validate the backups . Let me explain the context. Actually the backups are done via RMAN on local in a NFS share. After these backups are backep up by Netback on tape. The goal was just to validate that the…
By Mouhamadou Diaw In my previous blog, I described the steps to deploy an ODA 19.8 by reimaging. The ODA was reimaged with the latest available version 19.8 but some components were not up-to-dated. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 [root@serveroda ~]# odacli describe-component System Version ————— 19.8.0.0.0 Component Installed…
By Mouhamadou Diaw Recently I was deploying some ODA X8-2M. To install the 19.8 software, I decide to reimage the server with the 19.8 image. In this blog I describe the main steps I did. First, we will need to download following patches from Oracle support website -Patch 30403643: Oracle Database Appliance 19.8.0.0.0 OS ISO IMAGE for all platforms -Patch…
Introduction There is no need to decrease the number of cores on your ODA when using Standard Edition 2, because your license is based on the number of physical CPU. So why would you do that? Obviously, the more cores you have, the more performance you should get. But that simply isn’t always true. Base CPU speed and Turbo Boost…
Introduction A complaint I heard from customers about ODA is the low core speed of the Intel Xeon processor embedded in the X8-2 servers: Intel(R) Xeon(R) Gold 5218 CPU @ 2.30GHz. 2.30GHz only? Because of its comfortable number of cores (16 per processor), the cruise speed of each core is limited. Is it a problem compared to a home made…
Introduction I’ve been dreaming of this kind of feature: just because most of the ODA configurations now include Disaster Recovery capabilities, through Data Guard or Dbvisit standy. If Dbvisit will obviously never be integrated to odacli, the lack of Data Guard features is now solved by the very latest 19.8 ODA software appliance kit. How Data Guard was implemented before…
By Mouhamadou Diaw The ODA software 19.6 is released and people are starting to patch. A direct patch to version 19.6 is possible from version 18.8. Before patching your deployment to Oracle Database Appliance release 19.6, you must upgrade the operating system to Oracle Linux 7. In this blog I am describing the steps I follow when patching an ODA…
During ODA deployment I could see that starting 18.7, immediately after reimaging or patching the ODA, I was getting some regular errors in the root mail box. The error message came every hour at 13 minutes and 43 minutes. Problem analysis ksplice is now implemented and use in ODA Version 18.7. It is an open-source extension of the Linux kernel…
Recently I had to add some storage on an ODA X8-2M that I deployed early February. At that time the last available release was ODA 18.7. In this post I would like to share my experience and the challenge I could face. ODA X8-2M storage extension As per Oracle datasheet we can see that we have initially 2 NVMe SSDs…
Introduction With the latest ODA X8 range, at least 80% of the customers could find an ODA configuration that fits their needs. For the others, either they can’t afford it, either they are already in the Cloud, or they need extremely large storage or EXADATA performance. Among these 80% of customers, only a few choose ODA. Let’s see how Oracle…
I have recently faced an issue deleting database on an ODA. I was getting following error whatever database I wanted to delete : DCS-10001:Internal error encountered: null. Through this blog, I would like to share with you my experience on this case hoping it will help you if you are facing same problem. On this project I was using ODA…
During a past project, we were using ODA X8-2M with one additional network card. As per my knowledge, on an appliance, additional cards are used to extend connectivity to additional network. Customer was really enforcing to have network redundancy between the 2 cards. I then took opportunity for some tests. In this post, I would like to share my experience…
