Re: IPL Processing Sequence

I used to do this by habit in order to control everything via the
QSTRUPPGM but am currently re-thinking this approach.

My old approach has an inbuilt assumption that there will be access
available that does not rely on TCP, but I have been caught a couple
of times where this assumption has been faulty and QSTRUPPGM has been
changed to *NONE - thereby making access to the system problematic
where there is a console issue.

I often change QTSRUPPGM to *NONE when doing maintenance and this can
cause access issues if the console is compromised.

Rich,

It sounds a bit like your asking about the TCP/IP servers.  If you need
to control that use CHGIPLA to stop TCP from starting with
QSYSWRK/QUSRWRK start and then start TCP/IP and the balance of the TCP
servers manually in the start up program per your needs.

A discussion of the IPL steps from LIC to OS can be found at the Info
center under Systems Management, Work Management, Reference, IPL System
reference codes. Until the system is at a point where the the start up
program runs there's not much you can do with it unless you manually
IPL, then you have a small amount more control...  but I sense the start
up program is what your looking for.
