FAST RESTART OF APPLICATIONS USING SHARED MEMORY

摘要

Technologies are described for restarting an application while maintaining data in memory (e.g., using shared memory). For example, shared memory can be associated with an application. The shared memory can also be associated with a holder process to maintain the shared memory from the time the application stops to the time the application starts again. When the application starts, the shared memory can be associated with the started application. In addition, restart of in-memory databases can be provided using shared memory. For example, in-memory data can be maintained when a database process or database management system stops and starts (e.g., during a restart).

1. A method, implemented at least in part by a computing device, for restarting an application using shared memory, the method comprising:
associating shared memory with the application; associating the shared memory with a holder process; shutting down the application, wherein the holder process remains associated with the shared memory after the application has shut down; and after the application has been shut down, starting the application, comprising:
checking whether the shared memory is usable by the started application; andwhen the shared memory is usable, re-associating the shared memory with the started application for use by the started application.
