Hi Bai ,
Thanks for gud support,
Sorry for delay...
I will explain clearly so that u can understand the prob
Before truncating the mview logs avalable free space(dba_free_space) is --
SQL> select sum(BYTES)/1024/1024/1024 from dba_free_space;
SUM(BYTES)/1024/1024/1024
39.0560455
After truncating the mview logs available free space is ---
SQL> select sum(BYTES)/1024/1024/1024 from dba_free_space;
SUM(BYTES)/1024/1024/1024
251.980179
And these are the spaces cosumed by the tables corresponding tablespace...
SQL> select segment_name, bytes from dba_segments where tablespace_name='APPS_TS_TX_DATA' and segment_name like '%MLOG$%';
