Single-system and multi-system support
When working in a single system or in a multi-system non-Parallel Sysplex environment, Job Optimizer Pipes works in Local mode. In this mode, each system is managed separately. Applications that are running in parallel and sharing a pipe cannot run in different systems.
When working in a multi-system Parallel Sysplex environment, Job Optimizer Pipes can work in Local mode or Global mode. When working in Local mode, Job Optimizer Pipes manages each system separately. When working in Global mode, all the systems are handled as one system, which allows applications that are running in parallel and sharing a pipe to run in different systems.
When all participants of a pipe run in the same system, the pipe is called a Local pipe. Local pipes can be used when working in Local mode or in Global mode. When the participants of a pipe run in different systems, the pipe is called a Global pipe. Global pipes can be used only when working in Global mode.
A Global pipe is managed by Job Optimizer Pipes in the system on which the first writer of the pipe is executing. This system is called the Pipe Home System. Participants of a Global pipe that run in the Pipe Home System are called Local participants. Participants of a Global pipe that do not run in the Pipe Home System are called Remote participants.
