Abstract: Data is written to and read from a shared pipe by applications of multiple systems. At least one shared pipe is located within an external shared memory coupled to one or more central processing complexes. Each of the central processing complexes has one or more operating system images, which controls execution of one or more piping applications. At least one piping application corresponding to at least one operating system image writes data to a shared pipe located in the external shared memory and at least one other application corresponding to one or more other operating system images reads data from the same shared pipe, thereby providing cross-system data piping.

Abstract: A method and system are provided for executing a service processor request within a data processing system having one or more processors within a central processing complex, each of the processors within the central processing complex including allocatable processor resources. Each of the processors within the central processing complex is provided with the capability of processing selected service processor requests by reserving a portion of the allocatable processor resources within each of the processors for such purpose. A service processor request within the central processing complex is initially processed utilizing at least one of the processors in response to receiving a service processor request, if sufficient processor resources are available to process the service processor request within the reserved portion of the allocatable resources.

Abstract: An adapter interface function allows data to be acted on using resources owned by a corresponding application and without any modification to the application. The adapter interface can be applied to receive data from data sources not provided for in the access methods used by the application. Likewise, the adapter can be used to write data to data sinks not supported by the access methods used by the application. The adapter interface can be provided in an I/O control system or in access method programs. Adapters are written in an interpreted language to provide run-time execution and avoid program compile, assemble, and link edit requirements. A programing interface is provided to enable invocation of stored library programs.
