How do you know the time taken to execute a query in Oracle?
Answer: For seeing the elapsed time for an individual query, you can see individual query response time in SQL*Plus with the “set timing on” command. For DBA’s, Oracle has several tools for measuring system-wide response time using v$sysmetric, v$active_session_history, v$sqlarea and v$sysmetric_summary.
