Cause:
OSDBA has the wrong permissions on /etc/privgroup.


Solution:
1.Log in as the root user.
2.Using any text editor, open the /etc/privgroup file, or create it if
necessary.
3.Add or edit the following line, which begins with the name of the OSDBA
group, specifying the privileges RTPRIO and RTSCHED that you want to grant to
this group every time the system restarts (here dba is the OSDBA group):
dba RTPRIO RTSCHED
4.Save the file, and quit the text editor.
5.Enter the following command to grant the privileges to the OSDBA group:
# /usr/sbin/setprivgrp -f /etc/privgroup
6.Enter the following command to verify that the privileges are set
correctly:
# /usr/sbin/getprivgrp dba
