In a user session, tracing is enabled as follows:
SQL> EXECUTE
DBMS_TRACE.SET_PLSQL_TRACE(DBMS_TRACE.TRACE_ENABLED_LINES);
PL/SQL procedure successfully completed.
You executed the procedure as follows:
SQL> EXECUTE PROC10
PL/SQL procedure successfully completed.
When you examine the PLSQL_TRACE_EVENTS table, you find that no trace information was
written into it.
View the Exhibit.
What is the reason for this?
