Tuning and Troubleshooting OVO
Solving Installation Problems on MPE/iX Managed Nodes

If an Installation Aborts Because of Interactive
Login/Logout UDC
Installation aborts because of interactive login or logout UDC.
Problem
OVO uses vt3k during OVO agent software installation. During
installation, the interactive login and logout UDCs for MANAGER.SYS,
MGR.OVOPC and AGENT.OVOPC are not supported.
Solution
Deactivate interactive login and logout UDCs. Note that no interactive
login or logout UDCs are allowed.
If Starting an X-Application Causes an Unknown
Node Error
MPE/iX “request replies” from the OVO management server through
X-redirection from MPE/iX managed nodes fails.
Problem
Starting an X-application from the application desktop (or as an
operator-initiated action) produces an action annotation similar to the
following:
“unknown node: ERROR can’t open display”
Solution
Verify that the environment variable DISPLAY on the management server
is set to a long hostname (for example; xyz.deu.hp.com:0.0, not
xyz:0.0 or xyz:0). This display string is passed to the agent when it
tries to start the X-application by redirecting the display to the
management server. The agent may not be able to resolve the short
hostname. As a result, the agent may not be able to start the
X-application. If an operator-initiated action or automatic action started
the application, an annotation is added. If a desktop application or
broadcast command failed, an error dialog box pops up.
