To define CICS® as an MVS™ subsystem,
code an entry in the IEFSSNaa member in the SYS1.PARMLIB library.
If you want to use the console message handling facility, or
to change the number of pipes that can be allocated in an EXCI address
space,
code the entry by using one of the following methods:
CICS,DFHSSIN,DFHSSIyy
or
SUBSYS SUBNAME(CICS)
INITRTN(DFHSSIN)
INITPARM(DFHSSIyy)
This entry is used for every CICS region,
that you have IPLed with this version of the IEFSSN member, that runs
under MVS. You
do not have to specify both DFHSSIN and DFHSSIyy, however apart from
the suffix yy, you must code the entry for each parameter using the
exact format given in the example.
The meanings of the terms
are as follows:
If the DFHSSI00 member does not exist, the routine uses the default values.
The IEFSSNaa member in the SYS1.PARMLIB library also contains the definitions for all the other subsystems needed for this IPL of MVS, for example JES2, IRLM, and DATABASE 2 (DB2®).
