# title:        Check ability to change some database header attributes by non-sysdba user who is granted with necessary system privileges.
# decription:   
#                  Checked on 4.0.0.262.
#                  NB: attributes should be changed one at a time, i.e. one fbsvcmgr call should change only ONE atribute.
