To set the DISPLAY environment variable in a Bourne shell (sh5), issue the following commands, where workstation is the name of your workstation:
DISPLAY=workstation:0.0 export DISPLAY
Note that your workstation must be a Digital UNIX node running the CDE window server. Nodes running other operating systems and other window servers might work, but only Digital UNIX and CDE are guaranteed to work.
Also be sure your workstation permits Performance Manager to be displayed, if you are running Performance Manager remotely.
