DFHAC2003 created for default userid while running user transaction
Defining A CICS Default User
CICS Release 3.2.1 and above require the definition of a default user. This
userid is used for all security checking done before anyone signs onto a terminal. It is specified
in the CICS SIT parameter DFLTUSER.
The userid coded must be a valid ACID and have access to the CICS facility.
If the ACID is not properly defined or suspended, CICS will fail to initialize.
It is recommended that the ACID used be given limited authority to reduce the potential for
misuse.
In addition, the ACID should be given the NOSUS (no suspend) attribute, to keep it from being suspended.
