We know that during the ODA patching, a new grid version will be installed. To avoid the /u01 file system to fill up, we need to cleanup the old version. In this blog, I will show you how you can do it and also few changes coming with version 19.29, as you might need a reboot before. Remember that until…

This tutorial showing main steps how to perform upgrade, its not procedure to upgrade your production environment, please checkout official documentation from oracle and do proper planning and prechecks before you do…
I had to perform a duplicate database between 2 ODAs and was always facing an ORA-65500 at the begin of the RMAN operation. Looking a bit deeper in the log outputs pointed me out that it was due to some changes in the way RMAN makes the duplicate in 12c and cluster resources management. Basically up to 12c when RMAN…
In a previous article, I have shown how to configure two servers in order to deploy a two-nodes 12c cluster. This time, I am going to describe the Grid Infrastructure 12c installation process using Oracle Universal Installer (OUI). We assume that cluvfy tool has returned no errors (see previous blog). Install Grid Infrastructure Connect as grid and launch the Oracle…
La version 12c d’Oracle Grid Infrastructure introduit de nombreuses nouveautés dans le support d’ACFS, le système de fichiers clusterisés d’Oracle. Nous abordons dans ce posting la capacité d’ACFS d’être le système de fichier de votre base de données ainsi que sa capacité de mise en œuvre des snapshots.

Grid infrastructure 12c has recently been released. In this posting, I will show that the installation prerequisites are quite similar between Grid Infrastructure 11g and 12c. We will see parts of them during a review for the deployment of Grid Infrastructure on a two nodes RAC database cluster. Server hardware requirements Let’s see the hardware part. Grid infrastructure 12.1 Grid…
Dans ce blog post, nous allons nous intéresser à la gestion des PDBs (Pluggable Database) dans Oracle 12c. Plus exactement, nous allons nous pencher sur l’arrêt et le démarrage automatiques des PDBs en utilisant le Server Control (srvctl) du Grid Infrastructure de la 12c. Le contexte Au préalable, il faut avoir installé Grid Infrastructure et créé une CDB (Container Database)…
Last February, I performed an operating system rolling upgrade on a four-nodes RAC cluster (11.2.0.2). I then faced a strange problem when restarting the operating system… The first step of the procedure was to stop all Grid Infrastructure and Database services running on the first node as well as to disable Cluster and ASM autostart. The following command is supposed…
Last february, I had the chance to attend an Oracle presentation about ODA: Oracle Database Appliance. I found it interessant to share what I have learned about this technology. Which, I confess, convinced me. Summary Before developing the software and hardware components, here is a small overview of ODA. ODA is an all in one solution providing Hardware, Operating System,…
For a few day we had a quick request at a customer which was to replace a voting disk in an ASM disk group. The current ASM disk group (redundancy normal) had 3 disks : two located in one data center and one disk in another data center. The goal was to replace one voting disk (from the most used

A few days ago I downloaded the Cloud Control 12c binaries for Linux x86_64 from the Oracle Technet.
My friend, Hervé Schweitzer, configured an OEL 5.7 VM for test purpose and I was quite eager to install this new software. I checked the O.S settings, the required parameters, aso …, everything was fine. My OMS repository database (11.2.0.3) was ready.

My colleague Hervé Schweitzer reported a very interesting issue to me. It is about the usage of Grid Control 11g while monitoring the available space on an Oracle database – in our case a 10.2.0.3 target database. This post continues my last post about the free space management in a tablespace in relation to the recycle bin management.
