Overview

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.

Dynamic activation/deactivation

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).

To activate/deactivate a BSA trace via the "Display Modifiable Parameter Keywords/Values" panel:

1. In the "Primary Selection Menu" of the Beta product, enter D.S to display the BSA Service Manager.
2. Select option 1.2 to go to the "Display Modifiable Parameter Keywords/Values" panel.
3. Enter line command U (update) or I (insert) in front of the corresponding BSA trace keyword, enter the value Yes to activate or No to deactivate the trace, and then enter Y to confirm your change.

Direct activation/deactivation

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.)

To activate/deactivate a BSA trace directly via the corresponding LST parameter:

1. Open the corresponding member in the BETA.PARMLIB, e.g. B93LST00.
2. Specify the trace keyword and value, e.g. BQL_TRACE=YES or BQL_TRACE=NO.
3. Stop and restart the started task (STC).
4. In case of activation, allocate the medium as described.
