Which two components must always be defined or specified by an administrator to make an application highly available using Oracle 12c Clusterware?
Oracle Clusterware manages applications when they are registered as resources with Oracle Clusterware. Oracle Clusterware has access to application-specific primitives that have the ability to start, stop, and monitor a specific resource. Oracle Clusterware runs all resource-specific commands through an entity called an agent.
Note: When initializing the agent framework, if any of the mandatory entry points are not provided, then the agent framework invokes a script pointed to by the ACTION_SCRIPT resource attribute.
