Script to get size of generatedarchived logfiles in certain

timeframe

I’m testing a import datapump load procedure and I need to know the approximate size of 

generated archives that this load will generate to determine the size needed for our database

recoveryarea.

Script below queries the v$archived_log view for this information.

Please note that I have tested this with ONE and only ONE active / valid log_archive_dest

destination. I THINK that when there is more than one active log_archive_dest active these

archived log entries will be written to v$archived_log as well and the query will not ‘work’ anymore.

SQL> SELECT dest_id, status, dest_name, destination

2 FROM v$archive_dest_status

3 WHERE status <> 'INACTIVE'

4 /

  DEST_ID STATUS DEST_NAME DESTINATION

---------- --------- ------------------

--------------------------------------------------

1 DISABLED LOG_ARCHIVE_DEST_1

2 VALID LOG_ARCHIVE_DEST_2 /ora/recoveryarea/overflow/

col archives_m for 999,999,999,999,999

select round ( sum ( blocks * block_size ) /1024 /1024 ) archives_mfrom v$archived_log

where first_time > to_date( '2013-AUG-30-090000', 'YYYY-MON-DD-HH24MISS')

and first_time < SYSDATE

OK – I can report back to project the approximate size needed for our recoveryarea to ‘survive’

our new load interface.
