QUESTION: 180

You created two services HR and FINANCE on a single instance database. These services are used by the middle-tier applications to connect to the database by using connection pools.

  1. Using the DBMS_MONITOR.SERV_MOD_ACT_STAT_ENABLE procedure to collect statistics for a module and querying the V$SERVICE_EVENT view

  2. Using the DBMS_MONITOR.SERV_MOD_ACT_STAT_ENABLE procedure to collect statistics for a module and querying the V$SERVICE_STATS view

  3. Using the DBMS_MONITOR.SERV_MOD_ACT_STAT_ENABLE procedure to collect statistics for a module and querying the V$SERV_MOD_ACT_STATS view

  4. Querying the V$SERVICE_STATS view because the statistics for the modules are collected automatically when you invoke the DBMS_APPLICATION_INFO.SET_MODULE procedure
