Audit trail contains only what you asked Oracle to audit.

Please reply to the questions.

- Never ever use SYS (or SYSDBA) but for maintenance purpose (startup, shutdown, backup, recover)
- SYS/SYSDBA is special
- SYS/SYSDBA is Oracle proprietary (try to open a SR/TAR starting with "i did that with SYS/SYSDBA" and you'll see the immediate answer)
- SYS/SYSDBA does not act like any other user
- When you use SYS/SYSDBA Oracle deactivates some code path and activates others
- Whatever you do with SYS/SYSDBA will neither validate nor invalidate the same thing with any other user.

NEVER EVER use SYS/SYSDBA for anything that can be done by another user.
Use SYS/SYSDBA ONLY for something that can't be done by someone else.

Regards
Michel

Ask your DBA to give the user the privilege to execute it!

This sounds as though you need to enable extended auditing, which includes the SQL statements. If you want it to go to a file, your only option is
ALTER SYSTEM SET AUDIT_TRAIL=XML,EXTENDED;
and then use an XML viewer. So it is probably better to write the records to the sys.aud$ table with
ALTER SYSTEM SET AUDIT_TRAIL=DB,EXTENDED;
and then enable the auditing with
AUDIT ALL STATEMENTS BY whomever;
Time you read the security guide, http://www.oracle.com/pls/db112/to_toc?pathname=network.112%2Fe16543%2Ftoc.htm&remark=portal+%28Books%29
