Understanding RMC and resource managers

Edit online

An understanding of RMC and resource manager concepts is essential before performing resource management tasks.

Before performing resource management tasks, understand the following concepts:
  • How the RMC subsystem provides a generic way to represent, and manage various physical and logical system entities.
  • How a set of resource managers map information about specific entities to RMC's abstractions.
  • The representational components of RMC's generic framework. These include resources (the physical or logical system entities represented), attributes (characteristics of resources), and resource classes (sets of resources with common attributes).
  • The resource managing capabilities of RMC and the resource managers.
  • The monitoring capabilities of RMC and the resource managers (described in more detail later in Basic resource monitoring and Advanced resource monitoring).
  • How RMC implements authorization (described in more detail later in Managing user access to resources using RMC ACL files).
  • Differences between using RMC on a single node versus a cluster.
