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 of managing memory mapped input/output (I/O) for a run-time environment is disclosed, in which opaque references are used for accessing information blocks included in files used in a dynamic run-time environment. The information block is stored in a shared memory space of pages that are each aligned on respective boundaries having addresses that are each some multiple of two raised to an integer power. The opaque reference used for the dynamic run-time environment includes at least an index, or page number reference into a page map of references to the pages of the shared memory space, and an offset value indicating an offset into the referenced page for the beginning of the storage of the information block. Control bits of the opaque reference indicate information such as the mapping mode, e.g., read-only, read-write, or private. Pages which are modified by a process may be written back to a backing store of the file based on control bits which indicate that a page has been modified.

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.
摘要翻译：描述了处理转储文件中包含的堆快照的堆分析器。堆分析器工具可以配置为重定位转储堆中的指针，并允许开发人员通过在浏览器中显示堆对象的标记，并将对象中的指针呈现为可点击链接来检查Web浏览器中的堆。当选择链接时，指针跟随到另一个对象，并且生成标记以使其链接呈现该对象。此外，回调可以通过应用程序编程接口（API）提供，以允许开发人员提供自己的代码来分析和显示其数据结构。

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.

摘要： Backtraces are logged in the log file during execution of a program and tagged with information that can categorize the backtraces. Certain tags are also marked as “interesting” in the log file. A report is generated from the log file, indicating which of the backtraces are associated with the tags marked as interesting. In one embodiment, allocations of objects are logged with their addresses, and the objects that are later migrated into session memory are marked interesting.

摘要： A method and software for managing memory are provided in which objects residing in session memory are formatted so the references contained in the objects are in a machine-independent format, namely, that the references are encoded numerically. An exit table is provided to handle references with session memory that refer to locations in call memory, in which each entry in the exit table is associated with a corresponding reference in session memory and contains a pointer to the location in call memory.

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： Lazy evaluation is used for resolving references to recreatable external objects. A recreatable external object is an object whose state can easily be deallocated and later reconstituted or “activated” based on a much smaller sized descriptor. In one embodiment, a run-time external reference is used that specifies an index into a value array that holds the actual reference and a descriptor array. If the value array entry at the index is null, then the corresponding entry in the descriptor array is used to activate the external object and a reference to the activated external object is cached in the value array.
摘要翻译：懒惰评估用于解析对可再用外部对象的引用。可重新启动的外部对象是一个对象，它的状态可以很容易地被取消分配，并且随后基于小得多的描述符被重构或“激活”。在一个实施例中，使用运行时外部引用，其将索引指定为保存实际引用的值数组和描述符数组。如果索引处的值数组项为空，则描述符数组中的相应条目用于激活外部对象，并将激活的外部对象的引用缓存在值数组中。

摘要： A fast division technique is provided to calculate the address of a slot in a paged object, when the slot is located on a different page than the beginning of the object. The fast division technique employs arithmetical-logical operations of shifting and masking, that are faster than most hardware implementations of integer division and modulus, respectively. In one aspect, the use of these operations is facilitated by requiring the page size and the size of the page header to be a power of two.
摘要翻译：提供快速分割技术来计算分页对象中的时隙的地址，当时隙位于与对象开头不同的页面上时。快分割技术采用移位和掩蔽的算术逻辑运算，分别比整数除法和模数的大多数硬件实现要快。在一个方面，通过要求页面大小和页眉的大小为2的幂来促进这些操作的使用。
