Composition of Pipeline Service
Internal pipeline service that is the execution environment of pipeline is composed of the service process started and monitor process. Service process is called pipeline service, and has various functions including the processing engine of. This pipeline service is internally called PIPELINE-Service, and operates on JavaVM different from the monitor process. To distinguish explanation in this paragraph, we explain the pipeline service of environment execution including the monitor process as "Server" and explain the service process started by "Server" as "Pipeline service".
The pipeline service with the monitor process as a process with the instance of independent JavaVM (Java virtual machine) physically is in the memory. This is called service process. In addition, the service process has the process that is some functional processing modules internally, and this process consists on the frame to which two or more service requests can be processed with the multi thread at the same time. In service to compose "Server", monitor process is to start pipeline service as sub-process and stop, monitor operation of super-process.
