Abstract: The present invention provides a framework for managing both clustering and data replication in a software system distributed across multiple nodes. The framework includes at least one agent running at nodes comprising the distributed system. The framework also includes a master to coordinate clustering and replication operations. The framework further includes a library of software programs, called primitives, that are used by agents to communicate with the master. The agent(s) obtain cluster status information and replication status information, which are used by the master to manage clustering and replication operations. The framework is designed to work with existing cluster management applications and data replication facilities. The framework provides status information needed for coordinating clustering and replication operations to ensure that applications and data remain in a consistent state for disaster recovery purposes.

Abstract: A server self health monitor (SHM) system monitors the health of the server it resides on. The health of a server is determined by the health of all of a server's sub-systems and deployed applications. The SHM may make health check inquiries to server sub-systems periodically or based on external trigger events. The sub-systems perform self health checks on themselves and provide sub-system health information to requesting entities such as the SHM. Sub-systems self health updates may be based on internal events such as counters or changes in status or based on external entity requests. Corrective action may be performed upon sub-systems by the SHM depending on their health status or the health status of the server. Corrective action may also be performed by a sub-system upon itself.

Abstract: A system, method and software for isolating information handling system memory system devices are disclosed. In dual-channel double-data-rate memory system implementations, teachings of the present disclosure facilitate accurate identification of memory system devices that fail diagnostic testing or cause memory errors. A BIOS level application is provided which permits user or application selection and isolation of memory system devices or components, thereby eliminating the need for physical removal of such components during testing as well as permitting continued use of the information handling system with defective memory system devices isolated.

Abstract: In clusters of multiprocessor systems it is important that these processor nodes are aware of each others availability and performance capabilities. In highly available systems using these multiprocessor systems there needs to be a method to dynamically bring nodes both into the cluster and to remove nodes out of the cluster. The processor node that is responsible for these actions is designated the manager node (50). The manager node has a pre-selected backup to assume this responsibility upon the inability of said manager node to fulfill its duties. To allow the cluster of nodes to communicate with each other efficiently there needs to be a distributed messaging system that allows for the rapid distribution of data messages among the cluster nodes.

Abstract: Techniques for error handling are described for errors detected by a computer application that receives and processes application transaction data generated by a different computer application. A determination is made as to the type of error that has been detected. Based on the determination, error correction guidance is displayed to a user for use in using the computer application that received the application transaction data to correct the error. In response to receiving an indication that the error has been corrected by the user, processing of the application transaction data by the receiving computer application is initiated.

Abstract: Systems and methods for recovering data from a backup copy and for backing up data. When a recovery operation is initiated, recovery items are selected from backup groupings of the client. The recovery items can include backup groupings, writers, and writer components. After the recovery items are selected, backed up metadata for each selected writer is retrieved from the backed up data. The backed up metadata is then queried to identify the restore method of the writer. The data of the client is then recovered by implementing the restore method included in the backed up metadata of the writer. During a backup operation, some of the backup groupings, as well as the content of the backup groupings, can be individually selected for backup. In both backup and recovery, a visual indication may be provided to identify individual selectability.

Abstract: When a primary server executing a task fails in a computer system where a plurality of servers are connected to an external disk device via a network and the servers boot an operation system from the external disk device, task processing is taken over from the primary server to a server that is not executing a task in accordance with the following method. The method for taking over a task includes the steps of detecting that the primary server fails; searching the computer system for a server that has the same hardware configuration as that of the primary server and that is not running a task; enabling the server, searched for as a result of the search, to access the external disk device; and booting the server from the external disk device.
