Examples
1.$ SET PROCESS/PRIVILEGE=EXQUOTA
The SET PROCESS command in this example assigns the current
process the privilege of exceeding quotas.
2.$ SET PROCESS/NORESOURCE_WAIT
The SET PROCESS command in this example disables resource wait
mode for the current process.
3.$ RUN/PROCESS_NAME=TESTER CALC
%RUN-S-PROC_ID, identification of created process is 0005002F
$ SET PROCESS/PRIORITY=10 TESTER
The RUN command in this example creates a subprocess and gives
it the name TESTER. Subsequently, the SET PROCESS/PRIORITY
command assigns the subprocess a priority of 10.
4.$ SHOW PROCESS/SUBPROCESS
19-APR-2001 15:17:28.41 User: DAVIS Process ID: 31900218
Node: OCALA Process name: "DAVIS"
Processes in this tree:
DAVIS *
DAVIS_1
DAVIS_2
$ SET PROCESS/SUSPEND DAVIS_1
$
The SET PROCESS/SUSPEND command in this example suspends the
process DAVIS_1 such that ASTs can be delivered to it. Because
no keyword was specified, the /SUSPEND=SUPERVISOR version is
assumed.
5.$ SHOW PROCESS/SUBPROCESS OCALA::TESTA
19-APR-2001 12:17:24.45 User: TESTA Process ID: 31400208
Node: OCALA Process name: "TESTA"
Processes in this tree:
TESTA *
TESTA_1
TESTA_2
$ SET PROCESS OCALA::TESTA_2 /SUSPEND=KERNEL
$
The SET PROCESS/SUSPEND=KERNEL command in this example suspends
the process TESTA_2 on node OCALA such that no ASTs can be
delivered to it.

$
In this example, CPU 1 has user capability 8 enabled (user mask
= 80). User capability 8 is set for the initial kernel thread
of process CPUSCHED, and CPU affinity is set to 1. Either of
these settings forces the initial kernel thread to run only on
CPU 1, as shown by the SHOW PROCESS command.
Then, the SET PROCESS/NOAFFINITY/NOCAPABILITY command clears
all CPU affinities and user capability requirements for the
initial kernel thread of process (CPUSCHED), and the binding to
CPU 1 disappears.
7.$ SET PROCESS/SSLOG=(STATE=ON,COUNT=4)
This command turns on system service logging with four P2 space
buffers, each having a size of FE00(16) bytes. If the process
has SETPRV, CMKRNL, or CMEXEC privilege, argument values are
logged.
8.$ SET PROCESS/SSLOG=(STATE=UNLOAD)
This command stops logging and closes the log file.
