Activating z/OS UNIX in full function mo... > Step 1 - Create the OMVS procedure - Pg. 54

2.3.1 Step 1 - Create the OMVS procedure The OMVS cataloged procedure runs a program that initializes the kernel. The STARTUP_PROC statement in the BPXPRMxx PARMLIB member specifies the OMVS cataloged procedure. The default name is OMVS. Though not recommended, you can replace the OMVS procedure with a procedure that has a different name. If you use a started procedure other than OMVS, the replacement started procedure must also be a single jobstep procedure that invokes the BPXINIT program (EXEC PGM=BPXINIT). If it invokes any other program, OMVS initialization will fail. Create a JCL procedure for OMVS and place it in SYS1.PROCLIB (if it is not already there as a result of the z/OS installation process). The content of this started task (STC) member is shown in Figure 2-7.
