摘要： Methods of memory management in a run-time environment are described. A mechanism is provided for registering a routine to deinitialize or deallocate a large object at the end of a call (e.g. by setting it to null to unreference the object), which prevents the large object from being migrated into session memory, e.g. when live objects are migrated at the end of the call. This routine is called after the finalization of garbage collected objects that may use the large object. In a subsequent call, the large object is checked before use to determine if the object is deinitialized and re-initialized if the large object was deinitialized.

摘要： Methods for managing memory in a run-time environment are described, in which an object is activated by both initializing the object and registering a routine to deallocate or deactivate the object at the end of a call (e.g. by setting it to null to unreference the object), which prevents the object, which may be a large object, from being migrated into session memory. This deactivation routine is called after the finalization of garbage collected objects that may use the object. In a subsequent call, the object is checked before use to determine if the object is already activated and re-initialized if the object is not activated.
摘要翻译：描述了在运行时环境中管理存储器的方法，其中通过初始化对象和注册例程来激活对象，以在调用结束时释放或停用该对象（例如，通过将其设置为空，以使其不发送对象），这可以防止可能是大对象的对象被迁移到会话存储器中。在可能使用对象的垃圾收集对象的最终化之后调用此停用例程。在后续调用中，在使用前检查对象，以确定对象是否已被激活，如果对象未被激活，则重新初始化该对象。

摘要： A method and software for managing pointers to external objects in a run-time environment are described in which eager external references are provided that allow session memory objects to point directly to certain call memory objects with machine pointers. The eager external references contain enough information to recreate the call memory objects in call memory at the beginning of the call and fix the session memory objects to point to the new locations of the recreated call memory objects.
摘要翻译：描述了一种用于在运行时环境中管理指向外部对象的指针的方法和软件，其中提供了允许会话存储器对象使用机器指针直接指向某些调用存储器对象的渴望的外部引用。激烈的外部引用包含足够的信息，以在调用开始时重新创建调用存储器中的调用存储器对象，并修复会话存储器对象以指向重新创建的调用存储器对象的新位置。

摘要： Objects that are managed within a run-time environment are stored on N-bit aligned addresses. Due to the alignment restriction, the N least significant bits of a reference to an object are available for storing information about the storage properties of the object. This information is extractable by fast register operations. The storage properties can include the lifetime, format, and contiguity of the object, or a combination of these properties. If the run-time environment implements a generational garbage collector, the reference tags are used to encode whether or not the object is recently allocated.
摘要翻译：在运行时环境中管理的对象存储在N位对齐的地址上。由于对齐限制，对对象的引用的N个最低有效位可用于存储关于对象的存储属性的信息。该信息可以通过快速注册操作来提取。存储属性可以包括对象的生命周期，格式和连续性，或这些属性的组合。如果运行时环境实现代数垃圾收集器，则引用标记用于编码对象是否最近被分配。

摘要： Techniques for memory management or analysis with conservative garbage collectors is provided. The native stack is analyzed during runtime to identify within frames references to objects in the heap space. An amount of memory is calculated that represents the memory implicated by the reference. A log can be generated that conveys the frame, location of the reference in the frame and amount of memory implicated by the reference.

摘要： A method and apparatus for copying garbage collection is described. A set of ambiguously referenced objects is identified in a from-space. Live objects in the from-space which are not ambiguously referenced are moved to the to-space, and the ambiguously referenced are transfixed (i.e. left behind to reside in the from-space). The boundaries of the ambiguously referenced are determined. When moving objects to the to-space, the objects are moved into regions between boundaries of objects transfixed in the to-space.

摘要： A method and apparatus for performing copying garbage collection is provided. In a computer's memory, objects are stored in a permanent semispace. When a garbage collection event is detected, a garbage collection cycle is commenced. During the garbage collection cycle, the live objects in the permanent semispace are copied into a temporary semispace. After copying all the live objects into the temporary semispace, the live objects are then recopied into the permanent semispace.

摘要： A heap analyzer that processes a snapshot of the heap contained in a dump file is described. The heap analyzer tool can be configured to relocate the pointers in the dumped heap and allow developers to examine the heap in web browser by presenting markup for displaying a heap object in the browser and rendering pointers in the object as clickable links. When a link is selected, the pointer is followed to another object and markup is generated for rendering that object with its links. Furthermore, callbacks may be provided through an application programming interface (API) to allow developers to furnish their own code for analyzing and displaying their data structures.

摘要： A memory model for a run-time environment is disclosed that includes a process-specific area of memory where objects in call-specific area of memory and session-specific area of memory can be migrated to at the end of a database call. User-specific objects can be then migrated to the session-specific area of memory. In one embodiment, the process-specific area of memory can be saved in a disk file and used to hot start another instance of an application server.
