Candle-lite DB2 manual Displaying Ifcid Trace Data

Using the IFCID Trace Facility

At the point when you enter option S to select the IFCIDs (whether by trace type, trace class, or IFCID record) and to start the IFCID trace, OMEGAMON II for DB2 asks you to confirm your selection. If you choose to alter your selection, you can enter option R (reset selection). OMEGAMON II for DB2 then allows you to re-enter your selections.
