# 5 - X11
# 6 - reboot (Do NOT set initdefault to this)
#
id:5:initdefault:
Change id:5:initdefault: to id:3:initdefault:
Note: If you use a different run-level, be sure to match it when you set up the soft link in the next step.
6. Create soft link:
ln -s /etc/init.d/xvfb /etc/rc3.d/S75xvfb
This example uses run-level 3. If you intend to use XVFB in a different run-level, set up the soft link to the
appropriate /etc/rcx.d directory. (The run-level of your Linux system is specified in your /etc/inittab file ).
Note: Always make sure to check the setting and exporting of the DISPLAY variable and to start XVFB from
the soft link to help with consistent reporting performance.
7. Restart the server.
8. Verify that XVFB is running with the following command:
ps -ef | grep Xvfb
9. Set DISPLAY from the command line using:
DISPLAY=hostname:1.0
export DISPLAY
Previous lines can be added to .bash_profile or whatever profile you're using.
10. Start Servers.
Installing XVFB on AIX
For complete instructions for XVFB see the AIXwindows Programming Guide, Appendix E. The X Virtual Frame
Buffer is
http://publib16.boulder.ibm.com/pseries/en_US/aixprggd/aixwnpgd/xvfb.htm#xvfb.
1. Add the following line to /etc/initab:
xvfb:2:respawn:/usr/bin/X11/X -force -vfb -x abx -x dbe -x GLX :1 > /dev/null
2. Set DISPLAY by adding the following line to .profile:
DISPLAY=`hostname`:1.0
export DISPLAY
3. Restart the server machine.
4. Disable JIT on application server(s).
Determining the correct SSO settings for the Learning Management System
Single Sign-On (SSO), also known as single logon, is the process which permits users to move between different
Web applications or different parts of the same Web application hosted by the same or different physical machines,
without being prompted for a user name and password (or certificate) every time.
For example, if SSO is not used, you will have to log in to the Delivery Server every time you launch a course from
the LMM server. As such, SSO considerations should be carefully considered in your Learning Management System
deployment planning to allow for the greatest efficiency in logging in users. For further information on the Learning
