attraction

If resource A has an attraction dependency on resource B, then Oracle Clusterware prefers to place resource A on servers hosting resource B. Dependent resources, such as resource A in this case, are more likely to run on servers on which resources to which they have attraction dependencies are running. Oracle Clusterware places dependent resources on servers with resources to which they are attracted.

You can configure the attraction start dependency with the following constraints:

• START_DEPENDENCIES=attraction(intermediate:resourceB)

  Use the intermediate modifier to specify whether the resource is attracted to resources that are in the INTERMEDIATE state.

• START_DEPENDENCIES=attraction(type:resourceB.type)

  Use the type modifier to specify whether the dependency acts on a particular resource type. The dependent resource is attracted to the server hosting the greatest number of resources of a particular type.
