摘要： A computer implemented method, apparatus, and computer usable program code for managing a software partition in logical partitioned data processing system. A virtual root process is created for the software partition, wherein the virtual root process functions as a root process for the software partition. The set of child processes is re-parented to the virtual root process in response to termination of a process having a set of child processes.

摘要： A computer implemented method, apparatus, and computer program product for managing state data in a workload partitioned environment. Process state data for a process in a workload partition is saved. Process state data is used to restore the process to a given state. State data associated with open sockets and open files bound to the first process is saved. In response to a determination that the process is associated with a domain socket that is bound to a socket file, an absolute pathname for the socket file is saved. A domain socket associated with a connecting process in the workload partition uses the socket file to connect to a domain socket associated with a listening process in the same workload partition to enable the two processes to communicate with each other.

摘要： A computer implemented method, apparatus, and computer program product for checkpoint and restart of a process. In one embodiment, a process shell representing a restartable process is created on an arrival server in response to identifying a process on a departure server that is a restartable process. The process shell is frozen. A name of the restartable process, an identifier of the restartable process, and an identifier of a parent process of the restartable process is assigned to the process shell. The process shell is then unfrozen and exits. A parent process restarts the restartable process when the process shell exits.

摘要： A computer implemented method, apparatus, and computer program product for dynamically loading a module into an application address space. In response to receiving a checkpoint signal by a plurality of threads associated with an application running in a software partition, the plurality of threads rendezvous to a point outside an application text associated with the application. Rendezvousing the plurality of threads suspends execution of application text by the plurality of threads. The application text is moved out of an application address space for the application to form an available application address space. The available application address space is an address space that was occupied by the application text. A software module is moved into the available application address space.

摘要： A computer implemented method, data processing system, and computer program product for enabling the restoration of in-flight file descriptors during a checkpoint operation. Responsive to a checkpoint operation being initiated on a process in a workload partition, in-flight file pointers in an in-flight file queue on a socket bound to the process are identified. A file descriptor is instantiated in the process file table of the process for each identified in-flight file pointer in the in-flight file queue. After completion of the checkpoint operation, the in-flight file queue on the socket may be reconstructed in a restore operation using the instantiated file descriptors.

摘要： In a computer system divided into multiple separate workload partitions, wherein at least one of the partitions contains multiple applications, and a loopback interface is made available to each partition, a method is provided for routing packets from one application to another application. In one embodiment of the invention, each packet to be routed from one application to another application in the same home partition comprises a first packet, and all other packets comprise second packets. The method comprises the steps of assigning the same pre-specified IP address to each of the first packets, and routing each of the first packets from its home partition to a loopback interface at the IP network processing layer. The method further includes marking the first packets to identify the home partition of each first packet, and directing the marked first packets to a mechanism configured to deliver each first packet only to its home partition, in response to the markings. Each second packet is assigned the IP address of its intended destination, and routed thereto over the loopback interface.
