Starting an SCP Process Using the RUN Command
MEM pages
should not be specified. SCP processes ignore this option and are allocated 64 pages
of virtual data space.
OUT filename
identifies the log file used by the SCP process if either LOG * or LOGFILE * is
declared as a startup parameter. For help selecting an appropriate log file, see
Selecting a LOG File on page 2-11. Also see LOG filename LOGFILE filename on
page 2-6.
If the OUT option is missing, the command interpreter assigns a default logging file,
usually the home terminal. If the OUT option is included, but no filename is
specified, logging is inhibited. If the OUT option is followed by a file name, logging
output goes to that file.
PRI priority
specifies the execution priority of the process. The priority of the SCP process
should be higher than the priority of the applications it serves. A value of 190 is
suggested as a starting value.
SWAP volname
specifies the disk volume on which the process data area is swapped. If this option is
omitted, the volume containing the program file is used. This volume is also used
for extended memory swapping if you do not include the SWAPVOL startup
parameter in the RUN command.
TERM hometerm
specifies the process home terminal, which is used as an emergency output device.
If you omit this option, the process uses the home terminal of the command
interpreter process.
BACKUPCPU cpunum
specifies the backup CPU for a fault-tolerant process pair. You do not need to
include the BACKUPCPU keyword if cpunum is the first parameter following the
slash that ends the run options. Select cpunum from these values:
-1 requests that no backup process be initiated (default).
0...15 specifies a backup CPU, which must differ from the primary CPU.
