One of the more perplexing issues for an Oracle administrator is tracking the execution of an Oracle import. When a production system is down, IT managers are anxious to know the progress of the Oracle Import utility. For very large tables, the Oracle Import utility can take many hours, and the DBA needs to know the rate at which the utility is adding rows to the table. To monitor how fast rows are imported from a running import job, try the following method.

SELECT
    SUBSTR(sql_text, INSTR(sql_text,'INTO "'),30) table_name
  , rows_processed
  , ROUND( (sysdate-TO_DATE(first_load_time,'yyyy-mm-dd hh24:mi:ss'))*24*60,1) minutes
  , TRUNC(rows_processed/((sysdate-to_date(first_load_time,'yyyy-mm-dd hh24:mi:ss'))*24*60)) rows_per_minute
FROM
    sys.v_$sqlarea
WHERE
      sql_text like 'INSERT %INTO "%'
  AND command_type = 2
  AND open_versions > 0;
