DBA_ADVISOR_EXECUTIONS

DBA_ADVISOR_EXECUTIONS displays metadata information for task executions. For example, the SQL Performance Analyzer creates a minimum of three executions to perform a change impact analysis on a SQL workload. The first one collects performance data for the version of the workload before the change, the second one collects data for the version of the workload after the change, and the third one performs impact analysis. All of these executions belong to the same task and are grouped into this view. Similarly, the automatic SQL tuning task, SYS_AUTO_SQL_TUNING_TASK, creates a new execution for each tuning run.
