Printing and analyzing global traces
A trace must be active on the Db2 subsystem that you want to trace. For data sharing, the trace commands have member or group scope.
You can activate a trace at all members of a data sharing group by issuing the START TRACE command with the SCOPE(GROUP) parameter on one member of the data sharing group. Db2 routes the command to each member of the data sharing group. The trace output goes to the destination that is specified on the DEST parameter.
