How to trackback deletion of records without flashback ?

Hi There,

We are using 11g and we do not have flashback feature enabled.

I trying to investigate a deletion of records, need help as i am not able to tack deletion statements.

I have done following

1. Looking at logminer data ( it did not show any SQL which could cause mass deletion)

2. review All relavent Forms code / packages / procedure ( it did not show any statemet which can cause mass deletion)

3. Looking in dba_hist_sqltext and dba_hist_active_sess_history tables for any unusual sql => but sql_text is shown as bind variables and also did not show any sql which can do mass deletion.
