Platform-independent Runtime Managed Node
Problems and Solutions
Problem
MPE/iX “request replies” from the ITO management server via
X-redirection from MPE/iX managed nodes can fail.
Description
Starting an X-application from the application desktop (or as an
operator-initiated action etc.) produces the action annotation:
“
unknown node: ERROR can’t open display
” (or similar)
Solution
Check that the environment variable DISPLAY on the management
server is set to a long hostname; for example
xyz.bbn.hp.com:0.0
, not
xyz:0.0
. 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 nor, as a
consequence, start the X-application. If an operator-initiated or
auto-action started the application, an annotation will be added. If a
desktop application or broadcast command failed, an error dialog box
pops up.
Problem
The agent software installation on MPE/iX managed nodes fails with the
following error message:
vt3k_opcchk failed
Description
This happens when the variable LANG is set to a language other than C
on the MPE/iX managed node.
Solution
Always set LANG to C before installing the ITO agent software.
