You need to specify the storage key for the CICS® common work area (CWA), and the amount of storage required for the CWA on the CWAKEY and WRKAREA CICS system initialization parameters as follows:
CWAKEY=CICS
WRKAREA=2048
To ensure that Web User Interface exception trace entries are written to the CICS auxtrace data set, as required to achieve first failure data capture, you should specify the USERTR, SYSTR, and AUXTR CICS system initialization parameters as follows:
USERTR=ON
SYSTR=OFF
AUXTR=ON
You should specify the CPSMCONN CICS system initialization parameter to invoke CICSPlex® SM code automatically during CICS initialization and initialize the region as a CICSPlex SM Web User Interface server. This is the recommended alternative to specifying the CICSPlex SM WUI initialization and shutdown programs in initialization and shutdown program list tables (PLTPI and PLTSD):
CPSMCONN=WUI
You should specify the action CICS should take if, at
the next local midnight, the CICS time-of-day differs from the system
time-of-day by more than 30 minutes (for example, after setting clocks
forward or back to adjust for Summer and Winter time) as follows:
AUTORESETTIME=YES
Clients
should continue to issue the CEMT PERFORM RESET command.
In addition to specifying the necessary CICS system initialization parameters for CICSPlex SM local MAS execution, specify the appropriate CICS system initialization parameters to enable CICS Web Interface support, for your release of CICS. For example, TCPIP=YES for CICS Transaction Server for OS/390® version 1.3 or later.
For information about these parameters see the CICS System Definition Guide.
