Startup jobs 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.
- Scpf (start control program function)
- 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.
- Qwcbtclnup (job table cleanup)
- 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.
- Qlpsvr (software agreements acceptance)
- 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.
