3. The following example illustrates how the global execution limit is applied locally
to each NCL processing environment that sends NCL processes to an NCL queue:
Suppose that you create an NCL queue called ABC with an execution limit of 1 by
using the following command:
NCLQUEUE SET=ABC LIMIT=1
Suppose that USER1 opens one OCS window (which has a primary processing
environment associated with it). USER1 sends three long-running NCL processes
(PROC1, PROC2, and PROC3) to the NCL queue ABC. PROC1 begins execution
immediately while the other NCL processes are queued.
Additionally, suppose that USER2 simultaneously opens one OCS window.
USER2 sends five long-running NCL processes (PROCA, PROCB, PROCC,
PROCD, and PROCE) to the NCL queue ABC. PROCA begins execution
immediately while the other NCL processes are queued.
Thus, PROC1 and PROCA begin execution concurrently from NCL queue ABC
because they are sent to the NCL queue from different NCL processing
environments.
Suppose that you change the execution limit from 1 to 3 by using the following
command:
NCLQUEUE SET=ABC LIMIT=3
PROC1 and PROCA continue to execute; PROC2, PROC3, PROCB, and PROCC
begin to execute; and PROCD and PROCE remain queued.
