You need to collect and aggregate statistics for the ACCTG service and PAYROLL module, and execute: Where do you find the output of this command?
Correct Answer: A
When you enable statistics gathering for a specific service and module using DBMS_MONITOR.SERV_MOD_ACT_STAT_ENABLE, the output is aggregated and can be viewed using theV$SERV_MOD_ACT_STATSdynamic performance view. This view contains the cumulative statistics of database activity broken down by service and module, which is exactly what you collect when executing the provided command. * B (Incorrect):While many types of trace files are located in the Diagnostic Destination directory ( $ORACLE_BASE/diag), the aggregated statistics for services and modules are not written to trace files but are instead viewable through dynamic performance views. * C (Incorrect):TheV$SERVICE_STATSview provides service-level statistics but does not provide the * combined service/module-level breakdown. * D (Incorrect):The output of the PL/SQL block is not written to a file in the current working directory; it is stored in the data dictionary and accessible via dynamic performance views.
