摘要： A system and program product for facilitating computing-environment control of a resource to be accessed by existing program code is provided which includes transparently replacing an uncontrolled resource referenced by existing program code with a resource controlled by a computing environment. The protocol also includes transparently interposing at least one resource management service of the computing environment between the existing program code and the resource controlled by the computing environment, wherein the at least one resource management service provides computing-environment control of the resource to be accessed by the existing program code. The replacing of the uncontrolled resource prevents the existing program code from directly accessing the resource.

摘要： A method and apparatus for managing shared virtual storage in an information handling system in which each of a plurality of processes managed by an operating system has a virtual address space comprising a range of virtual addresses that are mapped to a corresponding set of real addresses representing addresses in real storage. The virtual address spaces are 64-bit address spaces requiring up to five levels of dynamic address translation (DAT) tables to map their virtual addresses to real addresses. One or more shared ranges of virtual addresses are defined that are mapped for each of a plurality of virtual address spaces to a common set of real addresses. The operating system manages these shared ranges using a system-level DAT table that reference a shared set of DAT tables used by the sharing address spaces for address translation, but is not attached to the hardware address translation facilities or used for address translation. The shared range of virtual addresses straddles the 242-byte boundary between ranges served by different third-level DAT tables and is situated between a lower private range and an upper private range so that an individual address space can map both a lower private range and a shared range using only three levels of DAT tables. Each shared address range may be shared with either global access rights, in which each participating process has the same access rights, or local access rights in which each participant may have different access rights to the given range. Access rights for each participant may be changed over the lifetime of the process.

摘要： In a client/server system, a method and apparatus for a listening daemon to distribute work and client connectivity across multiple processes each supporting multiple threads. Upon receiving a request from a client, a listening daemonaccepts the conversation, thus creating a socket. The listening daemon then does a putwork( ) call which places a work request on a system managed work queue. The work request behaves in a manner very similar to spawn in that it provides for parameters to be passed as well as transfer of ownership of the socket. In the meantime, server processes that are created either manually or by the operating system create multiple threads, which invoke a getwork( ) service to retrieve work requests created by the listening daemon. The getwork( ) service transfers the socket to the calling process and notifies the thread which file descriptors it has inherited. The thread is then able to process the client request and respond directly to the client without requiring an intermediate process to provide the communication link. The present invention allows a server in a client/server system to spread the workload across multiple threads in multiple processes, avoiding the creation of too many processes or too many threads in a single process. The direct transfer of the socket eliminates the unnecessary overhead typically required to rebind a new process to the client application.

摘要： A method and apparatus for controlling the assignment of units of work to workload enclaves in a client/server system in which units of work are organized into enclaves with the units of work in each enclave being managed as a single entity. Incoming work requests are queued for processing by one or more worker threads of one or more server processes. In response to the receipt of an incoming work request, a putwork() service of the operating system kernel defines an workload enclave for the work request and adds the work request to a queue of incoming work requests to enqueue the request. In response to a request from a worker thread for more work, a getwork() service of the operating system kernel removes a work request from the queue to dequeue the request and associates the worker thread with the enclave defined for the request. If a worker thread must create a new unit of work while processing a work request, it calls an appropriate service of the operating system kernel, which creates the new unit of work and associates the new process with the enclave of the worker thread. The worker thread is disassociated from the enclave upon completion of the work request.

摘要： Distributed computing environment (DCE) remote procedure calls (RPCs) are integrated with an advisory work load manager (WLM) to provide a way to intelligently dispatch RPC requests among the available application server processes. The routing decisions are made dynamically (for each RPC) based on interactions between the location broker and an advisory work load manager. Furthermore, when the system contains multiple coupled processors (tightly coupled within a single frame, or loosely coupled within a computing complex, a local area network (LAN) configuration, a distributed computing environment (DCE) cell, etc.), the invention extends to balance the processing of RPC requests and the associated client sessions across the coupled systems. Once a session is assigned to a given process, the invention also supports performance monitoring and reporting, dynamic system resource allocation for the RPC requests, and potentially any other benefits that may be available through the specific work load manager (WLM).
