Troubleshooting: Specific Problems
Solution C If you change the password on the managed nodes for default users of an
application startup from the ITO Application Desktop, you must adapt
the password in the ITO configuration, too. This is only necessary if the
application is configured as having a Window (Input/Output), and if no
appropriate .rhosts or /etc/hosts.equiv entry is available.
Description D When any kind of application is started (Window (Input/Output);
Window (Output Only); No Window) the calling user’s profile is
executed. If the overall execution takes more than 2 seconds or before
anything is written to standard output, ITO assumes that an error has
occurred and the application startup will be terminated.
Solution D Simplify the user’s profile so that it executes faster or writes more
information to standard output. Also, check that the user’s profile does
not prompt for specific input.
Description E The command path length (inclusive of parameters) is too long for an
application configured as having a Window (Input/Output). Only 70
characters are available for command path and resolved parameters
(such as $OPC_NODES).
Solution E Do not specify the full command path. Put this path in the executing
user’s PATH variable. Avoid hard-coded parameters and only pass
dynamic parameters. Instead of calling the application with lots of
hard-coded parameters, use a script which internally calls the application
with the required parameters. Instead of configuring this application to
run in a Window (Input/Output), set this option to No Window, and
start an hpterm/xterm on that managed node.
Problem Command broadcast or application startup does not work on all selected
systems.
Description A Not all systems are controlled. Command broadcasting and application
startup is only granted on controlled nodes and not on monitored,
messages-allowed, disabled or message-allowed nodes.
Solution A Change the node type of the managed nodes to controlled (unless the
node is an external node, in which case this is not possible).
Description B The command or application is not available on all selected systems.
Solution B Install the command or application where it is missing.
