摘要： A computer-implemented method is provided for reducing network traffic associated with live migration. The method comprises selecting a virtual machine on a first physical host for migration to a second physical host, and providing each application running in the selected virtual machine with notification that the migration has started. In response to receiving the notification that the migration has started, each application reducing the number of memory pages in use during the migration. The selected virtual machine and each application is then migrated from the first physical host to the second physical host, wherein the migration of each application includes migration of the reduced number of memory pages. Non-limiting examples of methods that may be used to reduce the number of memory pages includes identifying memory that contains garbage, reducing the size of the heap, increasing the pause time used for garbage collection, deferring just-in-time compilation of hot methods, and releasing caches and buffers.

摘要： A method of serialization in a data processing system includes serializing a mutable object utilizing a full serialization process, caching primitive data and metadata regarding the mutable object in binary format in cache and then checking whether primitive fields of the mutable object are modified. Thereafter, the mutable object is again serialized utilizing an abbreviated serialization process by reference to the cached primitive data and metadata if the primitive fields of the object are not modified. In the event that primitive fields of the object are modified, the full serialization process is utilized. Thereafter, the serialized mutable object is communicated to a distributed code element.

摘要： A method, system and computer program product for determining if a buffer is marked copy-on-write. A user applications selects a buffer in user space to store data involved in a write/read operation. The user application searches a table storing addresses of buffers in user space that are marked copy-on-write to determine if the address of the selected buffer is listed in the table. If the address is listed in the table, then the selected buffer is marked copy-on-write. If the address is not listed in the table, then the selected buffer is not marked copy-on-write. By having a table store a list of addresses of buffers in user space that are marked copy-on-write by the kernel, the user application is now able to know whether the buffer in user space is marked copy-on-write.

摘要： A method, system and computer program product for caching socket connections while ensuring that there are file descriptors available for the applications. File descriptor references and their referenced objects are stored in a predefined memory region of the heap (“file descriptor heap”). Each time a socket connection is cached, a file descriptor reference may be created to be associated with the socket connection's file descriptor, where the file descriptor reference references the object of the cached socket connection. In order to ensure that there are available file descriptors for the applications, the file descriptor references and their referenced objects are collected by the garbage collector in response to various events (e.g., too many file descriptors are open) thereby freeing the file descriptors that were previously associated with the collected connection objects to be used by the applications.

摘要： A data processing system includes a processor and data storage coupled to the processor. The data storage includes program code, that when executed by the processor, causes the data processing system to serialize a mutable object utilizing a full serialization process and to cache primitive data and metadata regarding the mutable object in binary format in cache. Thereafter, the mutable object is again serialized utilizing an abbreviated serialization process by reference to the cached primitive data and metadata, and the serialized mutable object is communicated to a distributed code element.
