IBM i PTF Guide, Volume 19, Number 28
July 19, 2017 Doug Bidwell
Firmware. That “stuff” in the middle that appeared in our world when the AS400 went away. In the beginning, when the computing world was created and this unique creation was created to be something special, there was an AS/400.
This was an all-in-one OS/TIMI/hardware computing solution. During its evolution, names have changed, compute, memory, storage, and I/O capacity has increased exponentially, and, several architectural changes have been made. Some changes have been comfortable, some not so much. One of the not-so-comfortable things is firmware. This firmware has been around forever, we just didn’t know it as a separate beast to deal with until IBM merged the i and the p into Power. Now we have to deal with it.
Firmware PTFs are included in all cumes and SF99875, Hardware and Related PTFs. It is strongly recommended that firmware be as current as possible. We have recently ran into a whole slew of customers that were downlevel and having performance problems at upgrade time as a result. The rules are a little more difficult with an HMC managed system, we’ll cover that next week.
This week’s new PTF Groups includes, for all three releases:
- Hardware and Related PTFs
- MQ for IBM i
- HTTP server
- Open Source Solutions
The PTF effort at IBM has resulted in several fixes you’ll want to partake of. As always, “Get Current!” You won’t regret it. To help you work through the PTFs, we have included an archive of the IBM i PTF Guide, which you can see below:
