VIRTUALIZE, CHECKPOINT, AND RESTART POSIX IPC OBJECTS DURING CHECKPOINTING AND RESTARTING OF A SOFTWARE PARTITION |
摘要 |
A WPAR is migrated. Responsive to starting a checkpoint process, data and control information is collected and stored for IPC objects in the WPAR. Responsive to receiving a request to restart the WPAR, a type of IPC object is determined. Responsive to a determination that the IPC object is not an IPC shared memory object, a kernel handle that a process wants to be used for a new IPC object is registered. A request to create a new IPC object comprising a name uniquely associated with the IPC object and a WPAR identifier is issued. An entry that matches the name and WPAR identifier is identified and a virtual kernel handle is retrieved. The new IPC object is created. The virtual kernel handle is mapped to a real kernel handle and returned to the process. Data and control information is retrieved and overlaid onto the new IPC object.
