Abstract: Systems, methods, and computer program products to perform an operation comprising monitoring a privileged storage of a computing system, wherein at least a portion of the privileged storage stores a microcode of the computing system, determining, based on the monitoring, that a first location of the privileged storage includes an instruction, determining that the first location is designated as an unused location of the privileged storage, and performing a predefined operation to remove the instruction from the first location of the privileged storage.

Abstract: A method, system and computer program product for optimizing memory management. An analytics engine receives from a computing device an execution sequence that led to the detected execution of an operation to create a new process, which involves copying of the parent process. The analytics engine searches profiles stored in a repository for patterns of execution sequences that match the received execution sequence. Upon identifying a stored pattern with an execution sequence within a threshold degree of similarity as the received execution sequence, the analytics engine instructs the computing device to handle the operation to create the new process in a certain manner based on the contents of the profile containing the matching stored pattern. For example, the computing device may be instructed to preemptively fail the operation in response to the profile indicating that the execution of the operation resulted in an out of memory error.

Abstract: A method may receive, at a first node, a first message with a first message data structure from a second node. The first message data structure may include a counter for each resource of a plurality of resources that is indicative of a most current age of a master copy of the resource known by the second node. The first node may include a current data structure with a counter for each resource that is indicative of a most current age of the master copy of the resource known by the first node. The method may determine whether at least one counter in the current data structure is older than the corresponding counter in the message data structure. The method may update the counter that is older, e.g., to learn the most current age of the master copy of the resource known by the second node, based on the determination.

Abstract: A method of managing a database may include, at a node, assigning a pre-assimilation value to a hardware instance identifier of a hardware component before the node is assimilated into a multi-node computing system. The method may also include receiving a post-assimilation value after the node has been assimilated into the multi-node computing system. The method may also include updating the pre-assimilation value with the post-assimilation value.

Abstract: Vital data components of a computer system are protected by a mechanism for detecting unauthorized alteration, preferably in the form of digital signatures to detect unauthorized alteration. A vital data validation mechanism is provided to verify that vital data modules have not been tampered with. The vital data validation mechanism verifies the current state of each vital data module, preferably by decrypting the digital signature. The validation mechanism also checks an alteration log to verify that no alterations have been made to the corresponding memory locations. The second verification is intended to detect whether a vital data module has been altered temporarily, and then restored to its initial state.
