ODA 19.11.: ORACLE_HOMEs on ACFS

By | Oracle | 4 Comments

Introduction Beginning with Oracle Database Appliance (ODA) 19.11. the ORACLE_BASE and ORACLE_HOMEs are created on ACFS. That’s good news, because there is much more space on ASM than on the internal disks, i.e. no space issues with /u01 anymore. So how does it work? ORACLE_BASE and ORACLE_HOME on ACFS When installing an ODA from scratch then ORACLE_BASE and ORACLE_HOME are already on ACFS. See an example of a freshly installed ODA X8-2M: [[email protected] ~]# odacli…

Deploying a KVM-based virtualized X8-2M ODA

By | Database Administration & Monitoring, Database management, Operation systems, Oracle | 2 Comments

Introduction Until now, High-Availability (HA) ODAs could have been deployed either in bare metal or in virtualized mode. Virtualized mode means that instead of installing a classic Linux system on the nodes, an OVM hypervisor (based on Xen) was deployed. This hypervisor had at least one VM, a special one called ODA BASE, holding all the databases and having direct path to ASM disks. Other VMs could be created, not for databases but for applications,…

Manage ODA patching with Data Guard or Dbvisit Standby

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

Introduction Building an Oracle infrastructure today without thinking about a Disaster Recovery solution (DR) is quite rare. This became obvious that a backup or a dump will not help if you do not know where to restore or import once your production server is down. And restoring a backup is definitely not the fastest way to bring back your database to life. As a consequence, Data Guard or Dbvisit Standby, depending on which edition you’re…

Does it still make sense to deploy a virtualized HA ODA in 2021?

By | Database management, Hardware & Storage, Operation systems, Oracle | No Comments

Introduction Starting from version 19.11 of the Oracle Database Appliance software bundle, OLVM will definitely replace OVM server as virtualization engine. This change has quite a big impact as there will be no more virtualized specific deployment. Bare metal will come as a standard for all ODAs, and creating VMs for applications, or even databases, will be possible on top of that, for sure if you need them. And you can decide later to use…

A typical ODA project (and why I love Oracle Database Appliance)

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

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…

ODA: odacli now supports Data Guard in 19.8

By | Database Administration & Monitoring, Database management, Hardware & Storage, Operation systems, Oracle | 2 Comments

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 19.8? Those who have been using ODA and Data Guard for a while know that…

ODA 19.6 is available

By | Database Administration & Monitoring, Database management, Hardware & Storage, Operation systems, Oracle | 6 Comments

Introduction It’s been 1 year now that 19c is available on-premise. Finally, 19c is now available today on ODA too, in a real production release. Let’s have a glance of what’s inside. Is 19.6 available for my old ODA? The 19.6 release, like most recent releases, is the same for all ODAs. But oldest ODAs will not support it. First-gen ODA (now 8 years old), X3-2 (7yo) and X4-2 (6yo) won’t support this very latest…

Should I go for ODA 19.5 or should I wait until 19.6?

By | Database Administration & Monitoring, Database management, Hardware & Storage, Operation systems, Oracle | No Comments

Introduction As you may know, Oracle Database 19c is available for new (X8-2) or older Oracle Database Appliances since several weeks. Current version is 19.5. But when you go to the official ODA documentation , it still first proposes version 18.7 not compatible with 19c databases. Here is why. 19c database is the final 12.2 First of all, 19c is an important release because it’s the terminal release of the 12.2, as 11.2.0.4 was for…
