<h1 class="topictitle1">Timeout interval for inactive jobs</h1>
<div><p>The timeout interval for inactive jobs system value specifies in
minutes how long the system allows a job to be inactive before taking action.</p>
<p>A workstation is considered inactive if it is waiting at a menu or display,
or if it is waiting for message input with no user interaction. User interaction
includes using the Enter key, paging functions, function keys, and help functions. </p>
<p>The system determines which jobs are inactive. For example if a user starts
a second interactive job at the same display device, then any interaction
such as the pressing the Enter key on either job causes both jobs to be marked
as active.</p>
<p>The timeout interval for inactive jobs system value works with the system
value that determines what action the system takes when an inactive job exceeds
the specified interval. For information of the related system value, see <a href="rzamvqinatmsgq.htm">Timeout interval action</a>.
When the system is started, it checks for inactive jobs that are at or exceeds
the timeout interval. If a system is started at 9:30 in the morning and the
timeout interval is set at 30 minutes, the system will check for inactive
jobs at 10:00, 10:30, 11:00, and so on. If it discovers a job that has been
inactive for 30 minutes or more, it takes the action specified by the timeout
interval action system value. These two system values provide security by
preventing users from leaving inactive workstations signed on. An inactive
workstation might allow an unauthorized person access to the system.</p>
<p>See <a href="#qinactitv__quickref">Quick reference</a> table
for an overview of the timeout interval for inactive jobs system value. </p>

<p><strong>Relationship to security policy</strong></p>
<p>Within your security policy you should inform users your company's expectations
for managing their signon activities. Inactive jobs pose a potential risk
to system resources because someone could gain access to your system through
an inactive terminal. However, normal job duties often interrupt users at
their workstations, so you need to provide some flexibility for these expected
interruptions. Using the interactive job system values provide a means to
maintain security of system resource and provide user's flexibility to perform
all their job responsibilities. Your security policy should state expectations
for users regarding signon activities to both their workstations and to system
to which they have access. For example, users are expected to password protected
their workstations and enable password protection every time they leave their
workstation. If they need to leave their workstation while performing a job
on the system, locking their workstation provides a first barrier to anyone
who tries to gain access to your system through that workstation. However,
password protection is only the first line of defense. Use the interactive
job system values to ensure that malicious users do not gain access to system
resources. </p>
<p>If a job exceeds the timeout interval for inactive jobs, the
system will take the specified timeout interval action. If this action is
to disconnect the job, the system will wait until the timeout interval has
elapsed before disconnecting the job. If this action is to end the job, the
system will wait until the timeout interval has elapsed before ending the
job. Assume you have set the inactive job timeout interval to 30 minutes and
the inactive job action to disconnect the job. Also assume that the disconnected
job timeout interval is 300 minutes or 5 hours. If a user forgets to signoff
at 9:30 a.m., the system disconnects her job at 10:00 a.m. and will end the
job at 3:00 p.m.</p>
<p>When the system ends the disconnected job, any data on the user's display
that has not yet been entered into the system will be lost. If the user signs
on to the same workstation before the disconnected job timeout elapses, then
the job resumes from the point where the system disconnected the job.</p>
