Infrastructure at your Service
Introduction Sometimes you face interesting challenges with unusual environment. One of my customer needed a automated and flexible backup solution. Said like that nothing very complex you will say. But if I mention that some databases were 60TB big with more than 30 filegroups and around 600 database data files each and moreover synchronized in an AlwayOn availability group, it is not the same story and you can easily imagine that working with standard backup…
Introduction For years, Oracle used the same mechanism for database versioning. A major version, represented by the first number. And then a release number, 1 for the very first edition, and a mature and reliable release 2 for production databases. Both of them having patchsets (the last number) and regular patchset updates (the date optionally displayed at the end) to remove bugs and to increase security. Jumping from release 1 to release 2 required a…
Introduction I’m not that excited with all these events arround Oracle technologies (and beyond) but it’s always a good place to learn new things, and maybe the most important, discover new ways of thinking. And regarding this point, I was not disappointed. Franck Pachot: serverless and distributed database Franck talked about scaling out, it means avoid monoliths. Most of the database servers are this kind of monoliths today. And he advises us to think microservices….
Today I participate to SOUG Day which takes place in Lausanne at the “Centre Pluriculturel et social d’Ouchy”.
Introduction I was reimaging an X6-2M ODA after various patching troubles, and everything was fine. After several databases created, the next ones could no more be created. DCS-10802: Insufficient disk space on file system: database. Expected free space (MB): {1}, available space (MB): {2} I’ve spent some time on it, and finally found the cause of the problem. And the solution. Context After successfully reimaged an X6-2M ODA with 18.5, and applied the patch for…
Sooner or later all of us have to change a parameter on the database. But how is this put into execution when using a Patroni cluster? Of course there are some specifics you have to consider. This post will give you a short introduction into this topic.
Since Oracle 11g files created by the database belong by default to the Linux group oinstall. Changing the default group after creating the central inventory is difficult. In this Blog I want to show how locally created archived redo can be in group dba instead of oinstall. One of my customers had the requirement to provide read-access on archived redo to an application for logmining. To ensure the application can access the archived redo, we…
Introduction Reimaging an ODA is a good practice for a lot of reasons. To make your ODA cleaner if it’s running for many years and if you patch regularly. To simplify patching because if you’re late you could have to apply multiple intermediate patches to reach the target version. Or simply because you need to change the configuration (for example network configuration) and you want to make things clean, and be sure that future patches…
Microsoft, Amazon, Google and Oracle offer infrastructure services whose names change, but the concepts remain the same. It may be that you are interested in the cloud too, but it’s still not clear because you find much information all over and it’s hard to make decisions. Isn’t it?
As a SQL Server DBA we have the habit to migrate databases from an instance to another one or to a new environment. But migrate a database from on-premise to the Azure Cloud is an operation that we don’t deal with every day. As a reminder, Azure SQL Database is a relational database-as-a-service (DBaaS) which gives the ability to manage your databases directly from the Cloud with the performance of your choose, reliability, security and…
