摘要： In an approach for managing read-modify-write operations within a network. Aspects of an embodiment of the present invention include an approach for managing read-modify-write operations within a network, wherein the approach includes a processor for determining that a lock associated with a component of a network is set. A processor identifies a key associated with the lock. A processor determines that the key associated with the lock has not been altered since a previous time cycle. A processor responsive to determining that the key associated with the lock has not been altered, determines that a lock timeout has expired for the key, wherein the lock timeout specifies, at least, a period of time. A processor responsive to determining that the lock timeout has expired for the key, releases the lock.

摘要： Apparatus and computer program products implement embodiments of the present invention that enable a computer system comprising networked computers to self-heal from a boot failure of one of the computers. In some embodiments, upon detecting a first computer having a memory and a physical boot device failing to successfully load a boot image, a second computer defines a virtual boot device in communication with the first computer and the second computer and having a boot image for the first computer. Subsequent to defining the virtual boot device, the second computer can configure the first computer to boot from the virtual boot device.

摘要： In an approach for distributed management of a network, a processor discovers a network, wherein the network is comprised of a plurality of nodes and an at least one switch. A processor identifies a first port associated with the at least one node. A processor identifies a link between the first port and a second port within the network. A processor determines the at least one link is properly configured. A processor selects a first node of the plurality of nodes to be a master node, wherein the master node is configured to manage the network. A processor initializes a routing table, wherein the routing table contains locations of each node in the plurality of nodes and a location of the at least one switch. A processor adjusts by the first node, the routing table based on the change to the network.

摘要： A computer program product, system, and method are provided for upgrading a kernel or kernel module with a configured persistent memory. A persistent memory space is configured in the memory to store application data from applications in user mode. A kernel executing in the memory is prevented from accessing the persistent memory space. A service is called to load an updated kernel in the memory to replace the kernel, wherein the applications have access to the persistent memory space after the updated kernel is loaded. The service may comprise a kernel execution mechanism that directly loads the updated kernel into the memory without a full reboot of the computer system. An extended memory kernel service may be loaded during a boot operation to reserve the persistent memory space as an extended memory space for use by the applications and prevent the kernel from accessing the persistent memory space.

摘要： Embodiments of the present invention are provided that include executing, by a processor, a software stack received from a first boot image, and retrieving and executing, by the processor, a second software stack. A writeable boot device such as a storage device with a removable medium is detected, and the second software stack is saved by replacing, on the writeable boot device, the first boot image with a second boot image comprising the second software stack. The second software stack is saved upon detecting the boot device having no boot image.
