RE: PTF apply philosophies



fixed

For many years, I've successfully done
option 8, Automatic IPL N, other options Y, 2=Apply immediate, set delayed PTFs
All PTFs would get applied except those needing an IPL
Some at IBM will say this is ok, others discourage it.

8. Install program temporary fix package
Device . . . . . . . . . *SERVICE Name, *SERVICE, *NONE
Automatic IPL . . . . . . N Y=Yes
N=No
Prompt for media . . . . 1 1=Single PTF volume set
2=Multiple PTF volume sets
3=Multiple volume sets and *SERVICE
Restart type . . . . . . *SYS *SYS, *FULL
Other options . . . . . . Y Y=Yes
N=No
Omit PTFs . . N Y=Yes, N=No
Apply type . . 2 1=Set all PTFs delayed
2=Apply immediate, set delayed PTFs
3=Apply only immediate PTFs

For individual PTF's yes but not groups. There are too many dependencies and co-requests to map out making it a nightmare. IBM does it in the group so you just apply the group at IPL. But if you want to waist a day mapping out what can and cannot be applied, go for it. But do you homework first.

Chris,

What are your thoughts on immediate PTF apply?

Thanks
Paul

We have a full system save followed by full IPL to apply all of the PTF monthly. If management cannot have your system down for routing maintenance every other month, they NEED to approve a HA system.

If they will not, start looking for a new job as you do not want to be there when something fails and the backup is 6 months old.

Management would like to minimize the IPL, PTF, and system save downtimes.
HA/DR Is out of the question.
Currently, I try to IPL Production every 2 months for PTF apply along with a system save.
The IPL and system save will probably go to 6 months or as needed.
90% of PTFs can be applied immediately without an IPL, however IBM does not recommend immediate apply for more than a single PTF.
Applying a large amount of PTFs immediately has caused issues in the past.
Permission has been granted for the PTF immediate apply, but I'm weary from previous issues.
