Troubleshooting: Specific Problems
Problem
User’s profile is not executed as expected when broadcasting a command
or starting an application.
Description
The profile of the executing user is executed before starting the
command/application on the managed node. The profile execution might
not work as expected under the following conditions:
• profile prompts in a loop for specific user input and does not provide a
default setting, if only
Return
has been pressed
• strange terminal settings are done
• the profile execution spends more than 2 seconds
Solution
See “How ITO Starts ITO Applications and Broadcasts on Managed
Nodes” on page 327.
Problem
Scripts or other actions on the managed node do not execute, and the
action agent log file reports
script not found
.
Description
The PATH variable prepared by the action agent was changed by a
startup file.
When ITO agents are started on a system where the korn shell is used
and root’s profile points to a startup file where PATH is set explicitly, the
PATH variable set by the action agent is lost after the script is executed
by korn shell.
Solution
Change the setup for user root so that the PATH variable is set by
extending it
PATH=$PATH:
/new/path/
Problem
The following error message is displayed:
Cannot create semaphore, invalid argument
Description
Semaphores are not set up properly in the kernel.
Solution
Use
ipcs
to report on the status of the inter-process communication
facilities. Re- configure the kernel accordingly.
