Reviewing CICS system initialization parameters for the WUI

Review these system initialization parameters when setting up a CICSPlex® SM Web user Interface server to ensure that CICS is properly configured.

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.
Use the following format:
```
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, specify the USERTR, SYSTR, and AUXTR CICS system initialization parameters:
```
USERTR=ON
SYSTR=OFF
AUXTR=ON
```
Specify the CPSMCONN CICS system initialization parameter to start CICSPlex SM code automatically during CICS initialization and initialize the region as a CICSPlex SM Web User Interface server.
```
CPSMCONN=WUI
```
Specify the action CICS takes 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):
```
AUTORESETTIME=IMMEDIATE
```
Clients continue to issue the CEMT PERFORM RESET command.
See Handling daylight saving time changes for CICSPlex SM for advice on how to set up and administer your CICSPlex SM for daylight saving.
In addition to specifying the necessary CICS system initialization parameters for running CICSPlex SM local MAS, specify the appropriate CICS system initialization parameters to provide CICS Web Interface support, for your release of CICS.
