CONFDATA

The CONFDATA parameter specifies whether CICS® is to redact sensitive data that might otherwise appear in CICS trace entries or in dumps.

CONFDATA={HIDE|SHOW}
HIDE
CICS is to redact user sensitive data from CICS trace entries. The action taken by CICS is subject to the individual CONFDATA attribute on the transaction resource definition.
SHOW
Data redaction is not in effect. User data is traced regardless of the CONFDATA option specified in transaction resource definitions. This option overrides the CONFDATA option in transaction resource definitions.

The CONFDATA system initialization parameter should usually be set to the default value of HIDE to avoid passwords in transport data accidentally being exposed in trace entries or dumps. Most problems can be diagnosed without this data. If it is necessary to reproduce problems with CONFDATA set to SHOW, be aware that password data could be exposed.

See Removing sensitive data from CICS trace using CONFDATA for details of the CONFDATA mechanism including the interaction between the CONFDATA system initialization parameter and the CONFDATA transaction attribute.

You cannot modify the CONFDATA system initialization parameter while CICS is running. You must restart CICS to apply a change.

Restriction: You can specify the CONFDATA parameter in the SIT, PARM, and SYSIN only.
