If Oracle
Database allows multiple instances to mount the same database
concurrently, then the CLUSTER_DATABASE initialization parameter setting
can make the database available to multiple instances. Database
behavior depends on the setting:
- If CLUSTER_DATABASE is false (default) for the first instance
that mounts a database, then only this instance can mount the database.
- If
CLUSTER_DATABASE is true for the first instance, then other instances
can mount the database if their CLUSTER_DATABASE parameter settings are
set to true. The number of instances that can mount the database is
subject to a predetermined maximum specified when creating the database
