▪ username: Name of the user whose procedure calls or triggers you want to trace. If multiple connections are using the same user name, then calls from all of those connections will be traced. Furthermore, if you are using Advanced Replication, the tracing is done not only for calls on the replica, but also calls that are propagated to the master database and then executed on the master database.

▪ entityname: Name of the procedure, trigger, or table for which you want to turn tracing on or off. If you specify a table name, output is generated for all triggers on that table. Trace is activated only when the specified user calls the procedure or trigger.
