BSC RJE processing z/OS JES2 Initialization and Tuning Guide SA32-0991-00 |

Reading, printing, and punching between the host processor and the RJE workstation are asynchronous events. For example, the processor is either transmitting print data or transmitting punch data or reading an input stream. For an explanation of how the remote operator can influence the order of these events, see Altering the sequence of operations from an RJE workstation. Communication between the local processor and BSC RJE workstations uses a JES2 facility, called multileaving, which simulates the transmission of multiple print and punch streams. Multileaving allows JES2 to receive multiple console messages and input streams. With multileaving, several operations can take place concurrently. Operators at RJE workstations that have no console can enter commands into the input stream in the normal manner. Command replies are scheduled back to the RJE workstation for printing on a remote printer. RMT generation is the JES2 procedure for generating multileaving remote terminal processor programs for RJE from programmable RJE workstations. An RJE workstation is established by a JES2 program, RMTGEN, during or after system installation. These programs allow multileaving workstations (see BSC multileaving workstations supported by JES2) to operate as RJE workstations with JES2. RMT generation requires other procedures for its processing; for example, procedures for allocating space and cataloging. It also requires certain spool data sets for job processing after generation. These procedures and data sets, also required by JES2 generation, are described in Controlling JES2 processes. |
