i have a doubt regarding cics programs running mode.
i have seen cics programs runnig in two modes
one is problem state and another one is supervisor state.
can you explain what is problem state and supervisor state ,
at what basis these things are segregated.
this is the topic i have seen from cics installation guide.
Although, in general, CICS runs in problem state, the CICS initialization
program, DFHSIP, needs to run in supervisor state for part of its
For a module to be able to run in supervisor state, it must be link-edited
as an authorized module into a partitioned data set, which must also be
defined to the operating system as APF-authorized. For CICS-supplied
modules, the link-editing has been done for you. The CICS-supplied DFHSIP
module is link-edited with the authorized attribute (using SETCODE AC(1)),
and is installed in the CICSTS12.CICS.SDFHAUTH library.
