ORA-13506 An attempt was made to perform operation with an invalid Start/End Snapshot Pair during AWR report creation

Question

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?

Answer 1

BEGIN
  DBMS_WORKLOAD_REPOSITORY.create_baseline (
    start_snap_id => --ANY Integer Number_Min Value, 
    end_snap_id   => --ANY Integer Number_Max value, ,
    baseline_name => '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.
