Setting a Planned Shutdown Time (Quiesce Time)

Setting the Control‑M monitor planned shutdown time (QUIESTIME) stops the submission of jobs that, according to their average execution time, cannot finish before the specified QUIESTIME. Setting a QUIESTIME only affects submission processing and not other Control‑M functions, such as post-processing.

QUIESTIME is not applied to jobs that have already issued an ELIGIBLE FOR RUN message in the log. Such jobs are submitted as scheduled.

QUIESTIME is set by the operator command

F CONTROLM,QUIESTIME=xxxx

In this command, xxxx is one of the values described in the following table:

Table 87 QUIESTIME Values

Value

Description

hhmm

Where

hh is the hour, based on a 24-hour clock

mm is the minute

The planned shutdown time before which, based on their execution time, jobs must end. If any jobs cannot end by that time, QUIESTIME stops their submission.

A QUIESTIME command using this value supersedes any previous shutdown time setting.

NOW

Immediately stops the submission of all jobs.

OFF

Cancels any QUIESTIME requests that are currently active.

D

Displays the current status of QUIESTIME, in the form of messages CTML19I and RUNL19I.

Message CTML19I appears in the IOA Log in the form

CTML19I QUIESTIME IS SET: yyyy

and message RNL19I appears in the System Log in the form

RUNL19I QUIESTIME IS SET: yyyy

where yyyy is hhmm, NOW, or OFF.

By default, QUIESTIME affects both tables and jobs. However, if the IGNQTMGR parameter in the CTMPARM member is set to Y, QUIESTIME only affects jobs.

Recycling of the Control-M monitor cancels the previously defined QUIESTIME. The QUIESTIME can be defined when the Control-M monitor is activated with the START command. For more details, see Activating the Control-M Monitor.
