DTSession in AIX
 

I installed vnc in AIX server. In startup file i have the following entries
#!/bin/sh
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
Xsetroot - solid white
/usr/dt/bin/dtsession &

But in my AIX server there is no bin folder under dt. Kindly let me know about dt folders and whats its use and why its not available in this server
