This release of CICS® Transaction Server is installed using the SMP/E RECEIVE, APPLY, and ACCEPT commands. The SMP/E dialogs may be used to accomplish the SMP/E installation steps.
The process is described in the CICS TS 3.1 Program Directory. It is in line with IBM® Corporate Standards, and may be familiar to those who have installed other z/OS® products.
The traditional method, DFHISTAR, of installing CICS Transaction Server is still available. The Program Directory indicates where information about DFHISTAR may be found in the CICS Transaction Server for z/OS Installation Guide.
In z/OS, do not install SVCs or PC routines that return control to their caller in any authorized mode: that is, in supervisor state, system PSW key, or APF-authorized. Doing so is contrary to the z/OS Statement of Integrity (http://www.ibm.com/systems/z/os/zos/features/racf/zos_integrity_statement.html).
If you invoke such services from CICS, you might compromise your system integrity, and any resultant problems will not be resolved by IBM Service.
