QPCB Command

Use the QPCB command to list currently active processes.

QPcb

Description

The QPCB command lists all active processes and the commands they are executing, generating a single line of output for each process. You can use this command to determine who is using the system before shutting down CA VM:Director with the END command.

Output from the QPCB command takes the following format:

The headings of the previously mentioned output is explained as the following:

PCB

Specifies address of the process control block for the process

Userid

Specifies the Userid that initiated the process

Name

Specifies the name of the process

PCB#

Specifies a hexadecimal identifier for the process. This same identifier appears in any message issued by the process.

Parent

Specifies the address of the PCB for the process's parent process (if there is no parent process, this values is 0000)

Root

Specifies address of the PCB for the processe's root process

VirtCPU

Specifies the virtual CPU time consumed by this process in seconds

R

Specifies root process

P

Specifies high-priority process

C

Specifies initiated from or associated with CA VM:Director service virtual machine console

W

Specifies asleep in NUCWAIT

S

Specifies waiting for an available semphore or resource

E

Specifies exited

D

Specifies been detached

.

Specifies process information is not true

Semaphore

Specifies an internal address of the location in memory where the process is waiting for a semaphore to be posted
