CEMT SET DUMPDS

Change the attributes of a CICS® dump data set.

In the CICS Explorer, the Regions operations view provides a functional equivalent to this command.

Description

You can use the SET DUMPDS command to open or close the active CICS dump data set, and specify whether the automatic switch to the inactive dump data set occurs when the active dump data set is full.

For more information about dumps, see What happens to a dump request if there is no dump table entry?.

Syntax

Press the Clear key to clear the screen. There are two ways to start this transaction:
  • Type CEMT SET DUMPDS (or suitable abbreviations for the keywords). The resulting display lists the current status, similar to that obtained by using the CEMT INQUIRE DUMPDS command. You can tab to the highlighted or blank fields and overtype them with the required values.
  • Type CEMT SET DUMPDS (or suitable abbreviations for the keywords), followed by one or more attribute settings that you want to change. For example, cemt s du o a opens the active dump data set and switches to the inactive dump data set only when the active dump data set is full.

Typing ? at the beginning of either the first or second line gives a syntax prompt. Resetting the values takes effect immediately.
