<h1 class="topictitle1">System startup jobs</h1>
|
|
<div><p><dfn class="term">Startup jobs</dfn> are system jobs that run
|
|
at IPL. They handle the tasks that get the operating system environment up
|
|
and ready for work. The following is a list of the various system startup
|
|
jobs.</p>
|
|
<dl><dt class="dlterm">Scpf (start control program function)</dt>
|
|
<dd>This is the central job when you start the system. Scpf starts the Qsysarb
|
|
series, but Qsysarb3 starts most of the other system jobs (not Qlus) and brings
|
|
the system to a usable state. This job remains active after the system starts,
|
|
providing an environment for the running of low-priority and possibly long-running
|
|
system functions. Scpf also runs during the power down (Pwrdwnsys) processing,
|
|
and is the job that ends the machine processing.</dd>
|
|
<dt class="dlterm">Qwcbtclnup (job table cleanup)</dt>
|
|
<dd>This job is used during the start of the system to ensure that the job
|
|
structures are available for use. It typically completes processing before
|
|
the end of the system startup, but it can continue running after the system
|
|
starts, if there are a lot of job structures to clean up. This system job
|
|
ends when it completes processing.</dd>
|
|
<dt class="dlterm">Qlpsvr (software agreements acceptance)</dt>
|
|
<dd>This job is automatically started during an IPL if online software agreements
|
|
need to be accepted. The job ends when all agreements are either accepted
|
|
or declined.</dd>
|
|
