TFDSCOM Commands
Guidelines
•
You can use the abbreviation ar in place of AUTORELOAD.
•
In an SMR processor, there is already a fixed time-out value of 45 seconds after a
dump has been taken, but before the first attempt at reloading the processor. The
larger of the TIMEOUT value specified in this command and the fixed time-out
value of 45 seconds will be used.
•
In DMR and TMR processors, the time-out is not used on the first reload attempt.
•
In an SMR processor, to determine when to reload a particular processor manually,
use TFDSCOM CONFIG command. If the processor state is CPU DOWN NO
DUMP or CPU DOWN, DUMP IN PROGRESS, wait until the processor state
changes to CPU DOWN DUMP. (Failure to do so causes memory dumps to be
lost.)
•
The TIMEOUT option controls only the delay of the first reload attempt. If it fails,
successive attempts are made every minute until the number of retries (as
specified by RETRY-RELOAD) is exhausted.
Example
AUTORELOAD OFF
AUTOSTIFLE
The AUTOSTIFLE command creates a stifling window during which a repeatedly failing
processor is no longer automatically reloaded.
The window is used to limit the impact of a continuously failing processor.
num-times
is the number of reloads allowed within num-hours. The valid range of values is 0
through 10. Setting the number to zero disables the AUTOSTIFLE function. The
default value is 3.
num-hours
is the number of hours in the interval window. The hours range from 0 through 168.
Setting the interval to zero disables the AUTOSTIFLE function. The default value is
24.
Guidelines
•
You can use the abbreviation as in place of AUTOSTIFLE.
•
Setting num-times or num-hours to zero disables AUTOSTIFLE.
•
AUTOSTIFLE prevents consistently failing processors from creating new dumps
indefinitely. TFDS stops reloading and dumping (for DMR and TMR processors) or
