Some BSA traces can be dynamically activated and deactivated while the started task (STC) is running. Others can only be activated and deactivated via the corresponding LST parameter in the EXEC parameter or parmlib member of the Beta Systems product. To find out whether a trace can be activated/deactivated dynamically, see column DAA? (Dynamic Activation Allowed) in the table of trace keywords.
You can activate/deactivate BSA traces dynamically with the help of the BSA Service Manager. You can use the "Display Modifiable Parameter Keywords/Values" panel (option 1.2) or you can use the "Dynamic Trace Activation/Deactivation" panel (option 2.7).

You can activate/deactivate BSA traces directly by specifying the corresponding LST keyword and value in the EXEC parameter or parmlib member of the Beta Systems product. (Parmlib members BnnLSTxx, where nn represents a Beta product number and xx any combination of numeric values or characters, are always used when the started task (STC) or batch job is started.)
