Answer 1

did you check my last post?  There is one SQL which will let you know the table with largest space wastage.  Could you please run that ? for tables that do not contain LONG or LONG RAW fiels you can reorganize via brtools. But if a table contains LONG or LONG RAW field then you have to do export /import method.
Please also find the SQL below.
SELECT * FROM
(SELECT
SUBSTR(TABLE_NAME, 1, 21) TABLE_NAME,
NUM_ROWS,
AVG_ROW_LEN ROWLEN,
BLOCKS,
ROUND((AVG_ROW_LEN + 1) * NUM_ROWS / 1000000, 0) NET_MB,
ROUND(BLOCKS * (8000 - 23 * INI_TRANS) *
(1 - PCT_FREE / 100) / 1000000, 0) GROSS_MB,
ROUND((BLOCKS * (8000 - 23 * INI_TRANS) * (1 - PCT_FREE / 100) -
(AVG_ROW_LEN + 1) * NUM_ROWS) / 1000000) "WASTED_MB"
FROM DBA_TABLES
WHERE
NUM_ROWS IS NOT NULL AND
OWNER LIKE 'SAP%' AND
PARTITIONED = 'NO' AND
(IOT_TYPE != 'IOT' OR IOT_TYPE IS NULL)
ORDER BY 7 DESC)
WHERE ROWNUM <=50;
If you need top 50 tables, you can run that, else you can change the number in the last line for top 10, 20 and so on tables.
