Chris, this table was modified around 3am and I checked this view around 10am. Maybe I need to create a TAR.

Hey Prakash,

I never knew about that dictionary table, so I looked it up and found...

These views describe tables that have been modified since the last time table statistics were gathered on them. The views are populated only for tables with the MONITORING attribute. They are not populated immediately, but after a time lapse (usually 3 hours).

Perhaps that explains the diff. Check it out.

Hello,

Oracle 8.1.6 on HP-UX 11.0

WFM_ADMIN_at_VGRAFO> select num_rows,last_analyzed,monitoring from user_tables where table_name = 'NOTES_LOG';

NUM_ROWS LAST_ANAL MON

---------------- ------- 1585697 14-MAY-02 YES

Last night, Informatica inserted rows into this table.

1 select inserts,updates,deletes from dba_tab_modifications 2* where table_name = 'NOTES_LOG'
WFM_ADMIN_at_VGRAFO> / INSERTS UPDATES DELETES

-------------- --------------- 6509 0 0

WFM_ADMIN_at_VGRAFO> select count(*) from notes_log;

COUNT(*)

1592488

The difference between yesterday's and today's count is 6791 which does not match the number in dba_tab_modifications.

Does this mean that I cannot rely on dba_tab_modifications?

TIA
Prakash
