Creating the RTCS subsystem started task PROC
Select a name to be used for the RTCS subsystem started task PROC.We recommend using the name OSZRTCS. This name is used in the z/OS START command which is issued by the RTCS Initiator (OSZSIRIS) to start the RTCS subsystem address space.
Copy the OSZ$RTCS member from the SMP/E TOSZCNTL target library to SYS1.PROCLIB or a JES-managed started task procedure library using the member name that you selected in Step 1.If you start RTCS under Master Subsystem and you use an unmodified MSTJCL00, you must use SYS1.PROCLIB for the started tasks that are started under the Master Subsystem. Otherwise, creating the PROC in SYS1.PROCLIB is not required. You can use any started task procedure library that is defined in the IEFPDSI DD statement concatenation in the Master Scheduler JCL containing the MSTJCLxx member of SYS1.PARMLIB.
If you start RTCS under your primary JES, you can place the PROC in one of the JES-managed started task PROCLIBs.
