ODA
ODA vnetwork bridge with no IP address
It is not mandatory to setup an IP address on a bridge interface. A bridge forwards packets at MAC layer. But of course, if I would like to reach the DB System or the Compute Instance from the ODA, then an IP address will be needed on the bridge interface. I have demonstrate and explain this in one of my…
ODA and Dbvisit : Create a SNAPSHOT database?
As you might know, Oracle doesn’t offer any disaster recovery solution for their Oracle Standard Edition databases. Oracle Data Guard ensures high availability, data protection and disaster recovery for Oracle Enterprise Edition database only. Dbvisit is a great disaster recovery solution for Oracle Standard Edition database, and you might be aware that you can now, as well, create snapshot databases…
Can we benefit from Oracle SEHA relocate and failover with dbvisit StandbyMP switchover?
I recently wrote an article about how to combine Oracle SEHA database running on ODA 2-HA and dbvisit StandbyMP solution. See my article here : https://www.dbi-services.com/blog/combine-oracle-seha-on-oda-with-dbvisit-standbymp/. But are really all those high availability and disaster recovering solutions working together? Do Oracle SEHA relocate and failover functionalities work in conjunction with dbvisit StandbyMP switchover? Let’s see and try it! Test environment…
Combine Oracle SEHA on ODA with Dbvisit StandbyMP?
I recently blog on Oracle SEHA on ODA, see my article https://www.dbi-services.com/blog/seha-on-oda/. Oracle SEHA is used for High Availability for Standard Edition. Dbvisit Standby is a Disaster Recovery well known application designed for Oracle Standard Edition. Dbvisit guarantees database continuity, and will reduce RTO and RPO. With Dbvisit we will limit business impact in case of failure like hardware, operating…

SEHA provides then cluster-based failover for single-instance Standard Edition Oracle Databases using Oracle Clustware. It is important to mention that Oracle removed Oracle RAC from SE2 Edition since 19c. Most important things to know…
Patching ODA HA from 19.10 to 19.17
By Mouhamadou Diaw In this blog I am describing an ODA HA (serveroda1 and serveroda2) patch from 19.10 to 19.17. The process is the same that patching a non-HA ODA. Few tasks may need to be done on both servers, otherwise all steps are done from one node. If there are some tasks needed on both nodes, we will specify.…
High Availability VMs on ODA
Virtualisation is now possible on the ODA whatever it is an ODA Lite or HA. The virtualisation is based on KVM and integrated with odacli for Bare Metal installation. Virtualisation has got the advantage to allocate resources to databases and applications on the same physical server. But what is the High Availability solution I have for virtualization on the ODA?…
