SELECT -- *
  record_id, message_text, originating_timestamp
FROM listnerlog
ORDER BY record_id;


-- The database timezone is set to UTC.  The timezone offset can be changed 
-- by executing script shown below

exec RDSADMIN.RDSADMIN_UTIL.alter_db_time_zone(p_new_tz => '-4:00');

SELECT * FROM TABLE(RDSADMIN.RDS_FILE_UTIL.listdir('DATA_PUMP_DIR'))
ORDER BY mtime;

-- Get export file (log) details that is used for data migration

SELECT * FROM

        p_directory => 'DATA_PUMP_DIR',
        p_filename  => 'exp_file.log')         --use exact log filename
  );

-- Get a list of files that are created in the ADUMP directory.  To execute this 
-- query, user needs to have READ access on the ADUMP directory

 SUBSTR(filename,-3) file_type,
 TO_CHAR(MIN(mtime),'mm/dd/yyyy') earliest_file,
