ORA-13506 An attempt was made to perform operation with an invalid Start/End Snapshot Pair during AWR report creation When I create an AWR Report, the following error occurs:


  ORA-13506
  Cause: An attempt was made to perform operation with an
  invalid Start/End Snapshot Pair.


What does this mean, and what should I do about it?
BEGIN
  DBMS_WORKLOAD_REPOSITORY.create_baseline (
    start_snap_id =&gt; --ANY Integer Number_Min Value, 
    end_snap_id   =&gt; --ANY Integer Number_Max value, ,
    baseline_name =&gt; 'batch baseline');
END;
/


So here min and max value are already in DBA_HIST_BASELINE view. You can't chose random value for snapshot.

Remember value already in oracle system, you can't drop value but not overbound.
