ODA: How is the storage managed in a non-RAC environment?
By uwes on Dec 23, 2011
Q: In particular, does the one Oracle instance see all the storage ? Also, is it possible to run two non-RAC instances on one ODA, one on each node ( I assume not ), and if so, how is the storage divided up?
A: The underlying software is Grid Infrastructure in alll cases (EE;
RAC One Node and RAC). It is the database that is either created as
single instance, RAC One Node Instance or 2 RAC Instances.
The storage is always shared.
Technically you can two Single Instances/databases (also discussed as EE) on ODA. One on each node. It is a matter of licensing. In most cases customers would buy EE and run one or more databases on this node(SC) and then use the 10-day rule in case of a failure.
If a customer would like to run a database on each SC then they have to license it.
