SHOWQ
Each entry in the three columns displays the following information for a single process; the
meaning is explained below.
{ A B C D E } [ M U ] pin [ #Jnnn #Snnn ]
A the queue attribute of the process is AS
B the queue attribute of the process is BS
C the queue attribute of the process is CS
D the queue attribute of the process is DS
E the queue attribute of the process is ES
M this is a job or session main process
U this is a user process
pin process identification number, a decimal
J nnn job number: a process executing in a batch job
S nnn session number: a process executing from a session
The process identification number (pin) may appear with or without an M or U label.
Processes without an M or U label are system processes.
In addition, SHOWQ prints the scheduling characteristics currently in effect. In the example
below, QUEUE is the scheduling subqueue and BASE, LIMIT, MIN QUANTUM, MAX
QUANTUM, BOOST and TIMESLICE are scheduling values set by the TUNE command.
MIN and MAX quantums are bounds for the quantums and ACTUAL quantum is the
current quantum value.

You may issue the SHOWQ command from a session, job, program, or in BREAK. Pressing
Break aborts the execution of this command. SHOWQ requires System Supervisor (OP)
capability.
NOTE The MPE/iX Scheduler now supports the workgroup concept. However,
backward compatibility is maintained through five default workgroups
created by the system. The scheduling characteristics of the CS_Default,
DS_Default, and ES_Default workgroups mimic those of the CS, DS, and ES
scheduling subqueues. In fact, the information displayed for the CS, DS, and
ES scheduling subqueues is the same information as that for the default
workgroups.
Please refer to the NEWWG and SHOWWG commands for more detail.
Since SHOWQ displays limited information regarding workgroup processes,
Workload Manager users should use the SHOWWG and SHOWPROC commands
rather than SHOWQ. Non-Workload Manager users may choose to use these
commands if they prefer the format for viewing the default workgroups.
