Hello,
I need to mirror datas in a second db (because the datas on db must be available 24h/24). I want to write datas in 2 db at the same time to have a second db if the first one crash.
If it exists a solution, how can i implement it ?

Good question!
Oracle claims that only way to mirror (something) is available through hardware and/or operating system (OTN).
Any other approach?
As I see with MS SQL, they have a concept of mirror for database space (devices) ...
Oracle is able to do it in this way?

what's diff between clustering & mirroring/replication
ITs not a simple thing to explain clustering and replication in one or two sentences.
1.Clustering is the concept of grouping different nodes and forming a single layer on which the database will be present.Again this clustering concept is for OS level and the type database option will be depend on u.Whether u have to opt for Parallel server of Oracle Fail safe.
2.As come to mirroring on OS level u are dealing with Storage devices and for database either it can be a Standby database.
3.AS for the replication either u can have a Multi master or a Snapshot.
Above things are need to be understand in deep and after going through the documentations and the search options still the things which u are not understand u can put them precisely on the forum so that it can be explain.
All the best
