Resource Management Options

Resource Management Options

There are two styles of configuring resource management for a RAC database:

  • administrator-managed configuration
  • policy-managed configuration

Each management style uses the concept of server pools, which are a logical division of a cluster into pools of servers.

Administrator-managed configuration 
  • is the management strategy used in previous releases. 
  • For this style, the database administrators define on which servers a database resource should run and place resources manually as needed. 
  • It uses a subpool of the built-in GENERIC server pool. 
  • This style is best suited for a small number of nodes due to the manual placement requirements.

Policy-managed configuration 
  • controls the placement of all resources by using server pools.
  • Database administrators specify in which server pool (excluding GENERIC or FREE ) the database resource will run. 
  • Oracle Clusterware is then responsible for placing the database resource on a specific server. 
  • It eliminates physically assigning resources to particular nodes in the cluster. 
  • This style is workload management compliant and best for a large number of nodes.
