Oracle RMAN Recovery

In my previous post I write about Oracle RMAN Backup, now I will explain a little bit about RMAN Recovery, there are many ways of using RMAN tools, but this is the way that i found to be succesfull.

Like I told you in my previous scenario I have a backup file that is copied to an NFS server from a tape server. The secondary server is also a running Oracle server that has its own instance that is being used. So my workaround for this recovery on a running Oracle server is to create a new Operating System user that is a member of oinstall and dba group, then create a new project on that user, so that the memory allocation is sufficient for the old and the recovered instance. For more detail you can see my next post on installing Oracle on Solaris. Continue reading

The scenario is started by configuring the primary database to be able to create rman backup then store the backup into tape (using veritas backup). Then the backup data is restored into an NFS server that is hosted on SUN Storage 7110. Then the secondary database will mount the NFS server. Continue reading
