Starting a trace in PowerScript with the PBTrace parameter – PB Docs 2017

Instead of tracing all database commands from the start of a
database connection, you can start and end a trace programmatically
for specific database queries. To start a trace, you can assign the
string value pair “PBTrace=1” to the transaction object DBParm
property; to end a trace, you assign the string value pair
“PBTrace=0”.

For example, if you wanted data to be logged to the trace output
for a single retrieve command, you could disable tracing from the
start of the connection and then surround the retrieve call with
DBParm property assignments as follows:

When you first connect to a database after setting the DBMS
parameter to “Trace DBMSName”, a configuration dialog box displays.
The configuration parameters that you set in this dialog box are saved
to the registry. Configuration parameters are retrieved from the
registry when you begin tracing by assigning the DBParm parameter to
“PBTrace=1”.

You can start and stop the SQL statement trace utility in the
same way if you set the DBMS value to “TRS DBMSName” instead of “Trace
DBMSName”. For information about the SQL statement trace utility, see
Using the SQL statement trace
utility.
