Review CICS system initialization parameters

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
Note:
Start of change
If you set AUXTR=OFF, this is overridden at startup. The Web User Interface sets auxiliary trace on in order to record exception trace entries in the event of a problem that does not result in a SVCDUMP.

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

Start of changeYou 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.End of change

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.
