DUMP

The DUMP system initialization parameter specifies whether the CICS dump domain is to take SDUMPs.

DUMP={YES|NO} (active and alternate)

Valid values are as follows:

YES: SDUMPs are produced, unless suppressed by the options specified in the CICS system dump table or by the MVS system defaults.
NO: SDUMPs are suppressed.
Note: This does not prevent the CICS kernel from taking SDUMPs.

For more information about SDUMPs, see System dumps.
