Re: Re: Question about LOADxx member
It's wonderful to check mailbox in the morning and
find these helpful reply:) Thanks.
I've tried the clist for invoking HCD and there is
some little difference in the system I tested on:
CBDCHCD is in SYS1.SCBDCLST,not in SYS1.ACBDCLST.Anyway,it's not a
problem.
Just as I've been told,it's rare occasion I
need to modify IODF.However,
knowing a little more about underlying OS principls would be
good for a
beginner like me.
By the way,I still dont think HCD invoked this way is equal to
the 'real' HCD for a real one
is independent of Z/OS and can be used even before Z/OS is
intalled . Is it right?
And this leads me to another question about emergency recovery
of ADCD Z/OS.For instance,
you did some modification to system data sets and on next IPL
found the system just broken down.
If you don't have another backup ADCD z/os,then what to
do?

No. you ca find the dataset of SYS1.ACBDCLST(CBDCHCD). CBDCHCD is a
clist file. you can execute it directly, or start it from a panel.
