A method and apparatus for resource dispersion in a clusterware system is provided. The resource profiles for resources within a cluster of nodes are stored. Each resource profile includes attributes for a resource. One or more of the attributes in one of the resource profiles includes a dispersion dependency attribute that specifies that the resource is preferably not co-located with another resource. Resources are placed within the cluster based, at least in part, on the dispersion preference.

Dispersion dependency in oracle clusterware

A method and computer-readable storage representing resources in a cluster by a plurality of attribute-value pairs that together are part of a 'resource profile,' in which each attribute-value pair defines all, or a portion of, a management policy that applies to the resource. A clusterware manager configures a resource according to the resource profile, and follows a resource profile syntax that specifies a runtime value for the resource in which an actual value is substituted at runtime.

Special values in oracle clusterware resource profiles

A method and computer-readable storage representing resources in a cluster by a plurality of attribute-value pairs that together are part of a 'resource profile,' in which each attribute-value pair defines all, or a portion of, a management policy that applies to the resource. Included is a built-in resource type called a 'Local Resource' type. Local resources that are attached to the server are instantiated with a combination of the resource profile and values of the Local Resource type.

'Local resource' type as a way to automate management of infrastructure resources in oracle clusterware

A clusterware manager configures a resource according to resource attributes values specified by a resource profile. The resource profile conforms to a resource profile syntax that the clusterware manager is configured to interpret pursuant to clusterware manager software. The resource profile syntax prescribes a start dependency syntax defining a dependency between a first resource and a second resource in which the second resource must be in an online state before the first resource is started. The resource profile syntax further prescribes a stop dependency syntax defining a dependency between a first resource and a second resource in which the first resource is brought in an off-line state when the second resource leaves an online state.
