Activities • $timingMsg {process} {runlevels} {checkPeriod/Time}
This activity causes a timing message to be sent to a specified process at
regular intervals whenever the system is at one of a specified run levels.
Currently, the TSM and the VROP processes expect to receive timing
messages once every 2 seconds.
• $hungProcess {process} {runlevels} {checkdPeriod/Time}
{timeout{fill|report|exec cmd}}
This activity causes a specific process, whose name appears in the
Bulletin Board, to be evaluated to see if it is hung in regard to reading its
messages. Processing only takes place when the system is at one of the
specified run levels. {timeout} is the length of time the process can stay in
the “working” state before being declared hung. Once a process is
determined to be hung, one of three responses are possible:
~ kill
The process is killed by sending it first a SIGUSR1 signal, followed by
a SIGKILL signal if it does not voluntarily exit.
~ report
A message is logged to the effect that the process is hung. No other
action is taken.
~ exec
The specified command is executed. The %p meta-word has the value
of the PID of the process associated with the rule.
