AUTO
DDF is automatically loaded and started when the Db2 subsystem is started. Start of changeAUTO is the default value.End of change
NO
DDF is not loaded at Db2 startup, and DDF cannot be started with a command.

If you specify NO, the stored procedures sample application and DDF sample jobs (DSNTEJ6, DSNTEJ6D, DSNTEJ6P, DSNTEJ6S, DSNTEJ6T, DSNTEJ6Z, DSNTEJ61, DSNTEJ62, DSNTEJ63, DSNTEJ64, DSNTEJ65, and DSNTEJ66) are not edited.

Also, the remaining fields on the DSNTIPR panel are ignored, so you can accept the default values.

COMMAND
DDF is loaded at Db2 startup but not started. However, DDF is prepared to receive the START DDF command.

If AUTO or COMMAND is specified, the DDF address space (ssnmDIST) is started when Db2 starts.
