START Command (Sensitive Command)
Use the START command to initiate the operation of an object.
START [ / OUT file-spec / ] [ object-spec ]
The value of object-spec is one of these object type and object name combinations.
object-type object-name
PROCESS $ZZKRN.#gpname
SERVERNET $ZSNET.{X|Y}.{cpu|*}
The START PROCESS command is described in the next subsection. The START SERVERNET
command is described on page 116.
START PROCESS Command
Use the START PROCESS command to start running a generic process.
START [ / OUT file-spec / ] PROCESS $ZZKRN.#gpname
PROCESS $ZZKRN.#gpname
is the name of a generic process controlled by the $ZZKRN Kernel subsystem manager. You
can omit PROCESS, $ZZKRN, and #gpname if you have specified them with an ASSUME
command.
START PROCESS Considerations
• “Starting a Generic Process” (page 53) describes how to use the START PROCESS command.
• It is recommended that you enter a TIMEOUT command (described in the SCF Reference
Manual for G-Series RVUs or the SCF Reference Manual for J-Series and H-Series RVUs) to
specify a timeout value that is larger than the default 90 seconds when starting a generic
process configured in multiple processors. Several processes can likely be started within the
90 second default. But if you start a generic process that has been configured as a group (by,
for example, the CPU ALL attribute), or if you start multiple generic processes (by using a wild
card in the ABORT command), more time may be needed.
• The START PROCESS command initiates execution of generic processes. Executing this
command directs the $ZPM persistence manager to create one or many processes, depending
on the values configured for the CPU, PRIMARYCPU, and BACKUPCPU attributes.
• If the start mode is not DISABLED but the processor in which the generic process is configured
is down, the START command puts the process into the STOPPED object state, substate
STOPPED. When the processor comes up, the generic process starts.
• If the start mode is not DISABLED and the processor in which the generic process is configured
is up, a successful START command puts the process into the STARTED object state.
• A successful completion of the START command indicates that this process (or processes, if
started in more than one processor) has been started (if its processor is up) and the startup
message has been sent to it.
• The START command sets the persistence count to the configured value.
