Well, I thought I answered your question earlier. Here are the steps, in
more detail.



I assume your database instance name is ORCL; replace with the actual.



(1) With your database open, issue a command as sys
SQL> create pfile from spfile.


(2) Go to the directory $ORACLE_HOME/dbs and make sue the timestamp of teh
file initORCL.ora file is now.

(3) Open the file and place the line audit_trail=db, if not already there.
(4) Shutdown the database.
(5) Restart




SQL> startup pfile=$ORACLE_HOME/dbs/initORCL.ora
(6) Make sure the audit trail is set.


SQL> show parameter audit_trail.


(7) resynch the SPfile.


SQL> create spfile from pfile;


(8) And, please let us know here if they worked. If any error occurs, copy
and paste the error here.



HTH.
