A Summary of Commands iCk, iCkAdmin

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{fillreportexec 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.
