Alter system set auditing failed

I issue 'alter system set audit_sys_operations=TRUE' but I got the following error. Pls help.

Error:
SQL> alter system set audit_sys_operations=TRUE;
alter system set audit_sys_operations=TRUE
*
ERROR at line 1:
ORA-02095: specified initialization parameter cannot be modified

That means this parameter cannot be modified dynamically. You need to make changes in the init.ora file and bounce the DB.
