Home >Oracle > Auditing for wrong sql
Simple and quick example auditing on insert, tested on Oracle 10.2.0.1.0. The context: I have some batch jobs and ETL application cannot insert data on a table. Programmers get Oracle errors such ORA-01722 but unfortunally cannot print out the wrong sql statements and so they have problem debugging. Programmers asked for DBA help. Among various Oracle tools, I pick up auditing tecnique. Auditing can be traced on files (OS) or on tables (DB, DB_EXTENDED). In this case I choose on tables. First, I make sure the Oracle initialisation parameters are properly setted, if not, I need to modify the parameter file and restart the db, in fact these parameter are not dynamic. audit_trail=DB_EXTENDED audit_sys_operations=TRUE audit insert on test.t1 by access whenever not successful; I use the clause access instead of session/font>, I want intercept any single statement on the table, and whenever not successful is precisely what I am looking for. Now that's all set, I try this basic test. Schema TEST got this simple table t1(n number,d date); Logged as TEST I execute the following insert statements: insert into t1 values(90,sysdate); insert into t1 values('aaa',sysdate); insert into t1 values(110,sysdate); insert into t1 values(110,to_date('2006-23-01','yyyy-mm-dd')); Lines 2 and 4 are obiously not correct (string instead a number, incorrect month). Logged as dba, I do aspect to find these incorrect statements on AUD$ table and in the dba_audit_trail view. So I run a query like this: select timestamp, userhost, terminal,owner,obj_name,action_name,returncode,sql_text from dba_audit_trail;
So it works as expected and I am ready for the serious work: incorrect insert actions have been recorded on the audit table. When I am over with audititing, I disable the audit: noaudit insert on test.t1; I disable the init parameters. To delete the sys.Aud$ table records, just delete them.
