-- Monitor the remaining time of SQL Execution. Do you know how long the running SQL takes? Do you know that the running SQL statement has completed about a few percent? Do you know how long it will take to complete running SQL statements? V $ SESSION_LONGOPS helps you. V $ SESSION_LONGOPS is described in <span style = "font-family: Arial, Helvetica, sans-serif;"> official documentation: </span> V $ SESSION_LONGOPS displays the status of varous operations that run for longer than 6 seconds (in absolute time ). these operations currently include existing backup and recovery functions, statistics gathering, and query execution, and more operations are added for every Oracle release. to monitor query execution progress, you must be using the cost-based optimizer and you must: Set the TIMED_STATISTICS or SQL _TRACE parameters to trueGather statistics for your objects with the DBMS_STATS package -- meaning: count the statements with each operation time greater than 6 S-prerequisites: The cost-based optimizer cboTIMED_STATISTICS or SQL _TRACE is true. The object has statistical information.
