20110179169 | 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. 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. | 07-21-2011 |
20110179170 | "Local Resource" Type As A Way To Automate Management Of Infrastructure Resources 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. 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. | 07-21-2011 |
20110179171 | Unidirectional Resource And Type Dependencies 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. | 07-21-2011 |
20110179172 | DISPERSION DEPENDENCY IN ORACLE CLUSTERWARE - 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. | 07-21-2011 |
20110179419 | DEPENDENCY ON A RESOURCE TYPE - A clusterware manager on a cluster of nodes interprets a resource profile. The resource profile defines resource profile attributes. The attributes include at least one attribute that defines a cluster dependency based on resource type. The attribute does not identify any particular resource of that resource type. Dependencies between resources are managed based on the attribute that specifies the cluster dependency. | 07-21-2011 |
20130219022 | HYPOTHETICAL POLICY AND EVENT EVALUATION - A cluster management system can facilitate determining a response to a hypothetical event by a computer cluster. During operation, the system can receive a request for a policy outcome from a user, such that the request can indicate a hypothetical event within a computer cluster. Next, the system determines a cluster state that includes state information from a plurality of server nodes in the cluster. The system then generates a response plan to the hypothetical event based on the cluster state, without executing the response plan in the cluster. The response plan indicates actions that are to be performed by server nodes in the cluster in response to the hypothetical event. The system then provides the response plan to the user. | 08-22-2013 |
20130219036 | ASSIGNING SERVER CATEGORIES TO SERVER NODES IN A HETEROGENEOUS CLUSTER - A cluster management system dynamically assigns a category to a server node based on the server node's attributes. The system can detect a change in value of a server attribute of a first server node. Then, in response to detecting the change in value of the server attribute, the system identifies a plurality of server attributes for the first server node, and dynamically assigns to the first server node a category that matches the server attributes. Further, the system can add the server node to a server pool that has a matching category with the server node. | 08-22-2013 |
20140096121 | FORCIBLY COMPLETING UPGRADE OF DISTRIBUTED SOFTWARE IN PRESENCE OF FAILURES - One embodiment of the present invention provides a system for facilitating an upgrade of a cluster of servers in the presence of one or more inaccessible nodes in the cluster. During operation, the system receives an instruction to upgrade an older version of a distributed software program installed on each of a plurality of nodes forming the cluster. The system installs and activates a newer version of software on a subset of the plurality of nodes, the subset having fewer nodes than the entire cluster. The system receives an instruction to forcibly upgrade the cluster. Subsequently, the system upgrades the cluster so that the subset of nodes operate with the newer version of software, in which each node remains a member of the cluster during the upgrade. | 04-03-2014 |
