tables used by online patching

Hi,

On R12.2 in maitenance guide p3-37 we have the following query:

-- Query 2: Returns actual table size

SQL>select table_name,round((num_rows*avg_row_len/1024),2)||'kb'

"size"

from DBA_tables

where table_name = '<table-name>'

and owner = 'table-owner>';

But I cannot understand what should be the table_name.

Is it the same :'AD_ZD_DDL_HANDLER' as query1?

Thanks for help.
