Single-CPU Configuration with Single Control-M System

The following figure shows a Single-CPU configuration with a Single Control‑M System:

Figure 33 Single-CPU Configuration with Single Control-M System

In the configuration illustrated above, Control‑M is running on one mainframe computer. It includes

• at least one disk volume containing the JES Spool
• at least one disk volume containing the IOA Core and Control‑M Repository
• at least one terminal capable of operating the IOA and Control‑M Online facilities

Standard terminals of the 3270 family are supported as well as other devices that emulate a 3270 terminal (such as a PC with 3270 simulation or a VT100 with 3270 simulation).

IBM DBCS terminals (or equivalent), which provide Japanese language (Kanji) capability, are supported as well.

Optionally, an RJE (Remote Job Entry) workstation (or an intelligent system that emulates an RJE station) can be connected to the mainframe. Under JES3, the same facility is called RJP (Remote Job Processing).

The following Control‑M features support RJE:

• The Control‑M Event Manager (CMEM) can be used to

— acknowledge and handle jobs submitted from RJE to MVS

— acknowledge the creation or deletion of datasets by jobs that originated from RJE

• Control‑M SYSOUT options support the routing of SYSOUTs to RJE.
• RJE jobs can invoke utility IOACND, or other IOA and/or Control‑M utilities using a JCL step to communicate with Control‑M.
