If SEC=YES is specified, external security is required. If external security cannot be provided, CICS® cannot be initialized.
Figure 1 shows an example of a failure to initialize.
A return code of X'00000004' indicates that an error occurred in the MVS™ security router (RACROUTE). See the RACROUTE macro reference in CICS security control points.
Figure 1 shows that XPPT=UNKNOWN has been specified. This causes CICS to try to use a class called MUNKNOWN. MUNKNOWN has not been defined to the MVS router, or to the RACF CDT.
