摘要： A method and apparatus for reducing time needed to initialize a data processing system and to execute applications on the data processing system. In accordance with a preferred embodiment of the present invention, pages for an application are pre-loaded onto a client from a server. The pre-loading of the application includes loading pages that will be required for execution of the application in preparation for hibernation. These pages may include other pages for executable code or data that will be used during execution of the application. Subsequently, the application is executed using the locally stored pages without having to retrieve pages from the server. In addition, an application is provided with an opportunity to prepare itself for hibernation via hibernation notification. For example, the application may read and process files from the server. This processing is done once prior to hibernation and is not required for later executions of the application.

摘要： A method in a data processing system for managing memory within the data processing system. A discardable page that is to be removed from the memory is identified. A determination is made as to whether performance will increase by storing the discardable page in a paging device located within the data processing system. If it is determined that performance will increase, the discardable page is marked as a paged discardable page and stored in the paging device locally, wherein this page may be retrieved from the paging device. The paging device may take the form of a paging file, such as a swap file. If space is unavailable within the paging device, the discardable page may be discarded. These processes may be implemented in a network computer.
摘要翻译：一种用于管理数据处理系统内的存储器的数据处理系统中的方法。识别要从内存中删除的可丢弃页面。通过将可丢弃的页面存储在位于数据处理系统内的寻呼装置来确定性能是否增加。如果确定性能将增加，则可丢弃页面被标记为分页可丢弃页面并且在本地存储在寻呼设备中，其中可以从寻呼设备检索该页面。寻呼设备可以采取诸如交换文件之类的寻呼文件的形式。如果寻呼设备中的空间不可用，则可丢弃可丢弃的页面。这些过程可以在网络计算机中实现。

摘要： A method and apparatus provides initializing a data processing system within a distributed data processing system. The data processing system receives data wherein the data is used to initialize the data processing system. The data processing system saves an image within the data processing system in a selected state after initialization of the data processing system, wherein the image is a saved image. The data processing system restores to the state using the saved image.

摘要： A client station on computer network uses an operating system such as JavaOS which is permanently stored at the server rather than on storage media at the client location. JavaOS is loaded and installed at the client upon bootup of the client. Java is an interpreted language; the source is available at the server and is downloaded as such. Upon the occurrence of a malfunction that causes the client to go off-line, i.e., disappear from the network, a dump image is sent to the server before the client reboots, so that the cause of failure can be determined. The dump image includes the contents of memory, including the JavaOS operating system, and the stack, threads, registers, and local/global variables, which can be analyzed at a source level. This image is sent to the server in formatted packets, by a path separate from that of the TCP/IP network protocol, since the client would not be functioning properly on the network. At the server, the packets making up the dump image are stored on storage media, and the image is reformatted for use by a standard debugging tool, ICAT.
摘要翻译：计算机网络上的客户端站使用诸如JavaOS的操作系统，该操作系统永久存储在服务器而不是存储在客户端的存储介质上。 JavaOS在客户端启动时被加载并安装在客户端。 Java是一种解释语言; 源在服务器上可用，并且这样下载。当出现导致客户端离线的故障，即从网络消失时，在客户端重新启动之前，将转储映像发送到服务器，从而可以确定故障原因。转储映像包括内存的内容，包括JavaOS操作系统，以及可以在源级别分析的堆栈，线程，寄存器和本地/全局变量。通过与TCP / IP网络协议的路径分开的路径，此映像以格式化的数据包发送到服务器，因为客户端在网络上将无法正常运行。在服务器上，构成转储映像的数据包存储在存储介质上，重新格式化映像，以供标准调试工具ICAT使用。

摘要： A method and apparatus for executing and debugging programs in a data processing system. The data processing system includes a first dispatch table, wherein the dispatch table is located at a dispatch table address and wherein the dispatch table includes addresses to routines executed for bytecodes. A second dispatch table is provided in which the second dispatch table includes addresses to routines for analyzing a program and addresses to the routines executed for bytecodes. The data processing system includes an interpreter, wherein the interpreter accesses a dispatch table located at the dispatch table address to process bytecodes. The first dispatch table is saved in response to a request to analyze a program. The second dispatch table is copied to the dispatch table address in response to saving of the dispatch table.

摘要： A converter program creates a simulated executable portion of code so that the operating system loader believes that a read only file stored on a hard drive of data consists of executable code and thereby memory-maps the read only file into virtual memory from storage. The result is that a large database may be memory-mapped into the processor virtual memory instead of the file having to be opened using standard file application program interface operations.

摘要： A data processing system and method manage the storage of instructions used in applications developed using an interpretive programming language, such as Java, REXX, BASIC, and the like, when those instructions are compiled into byte-codes to be used by a virtual machine stored in a “heap.” In the data processing system and method, an exception is registered in a page manager of an operating system to identify that compiled code should be stored within the heap of the virtual machine. After that code has been compiled and deleted from the heap, an exception occurs when the virtual machine attempts to subsequently access the compiled code. At that point, the virtual machine is then enabled to retrieve the desired code from an interpreted programming language application.

摘要： A graphical user interface layout is defined by a resource definition file having a set of resource directives associated therewith. A method of translating the layout to native Java source code begins by identifying each resource file directive associated with the window layout. For each resource file directive, or for each subdirective within a file directive or subdirective, the method generates a stub or "snippet" of Java code. The Java code snippets may be generated by direct code or by using a text-editable file interface, and the snippets are then combined to created a Java source file.
摘要翻译：图形用户界面布局由具有与其相关联的一组资源指令的资源定义文件定义。将布局转换为本地Java源代码的方法首先标识与窗口布局相关联的每个资源文件指令。对于每个资源文件指令，或对于文件指令或子目录中的每个子目录，该方法生成Java代码的存根或“片段”。可以通过直接代码或使用文本可编辑的文件界面生成Java代码片段，然后将代码段组合起来创建Java源文件。
