Troubleshooting: Specific Problems
MPE/iX Managed Node Runtime Problems and
Solutions
Problem
Extremely long time for command broadcasting and application startup.
Description
The command broadcasting and application startup are done within jobs.
When the job limit is reached, the jobs are queued. Non-ITO jobs also
increase the number of running/pending jobs. By default, ITO runs one
job to control its agents and up to four additional jobs for command
broadcasting and/or application startup.
Solution
Increment the job limit (HPJOBLIMIT) if required.
Problem
When distributing
command
,
action,
or
monitor
scripts or programs, it
may happen that current actions, commands, and monitors cannot be
replaced.
Description
The
commands
,
actions
, or
monitors
are still in use (scripts or
programs are running; text file is busy). The user receives a warning to
this effect. In most cases, this causes no problems, since the existing
actions, monitors, or commands are not often modified (in other words,
the newly-distributed files are equivalent to those in use).
Solution
If the user wants explicitly to change a program or script on MPE/iX
which is running, he or she must: Stop the MPE agents:
opcragt -stop <MPE-NODE>
Repeat the distribution (the distribution will restart the agents again).
