Re: perm apply ptf's -- DOMINO400

Bob,

I believe you are pretty much right with that. However, I think that the A 
side is meant only for permanently applied MF (hardware) PTFs and that 
software PTFs would be the same as on the B side.

OK, I think I was right as I found this to confirm...and the statement 
that "when the operating system is upgraded to a new release, the A side 
and B side match." leads me to think that it may be unnecessary to perm 
apply the PTFs before installing a new release. Although, it is in IBM's 
documentation that you should do this.

http://www-912.ibm.com/s_dir/slkbase.nsf/3cdf5d853ca698198625680b00020369/6e3958aef5fb1646862565c2007d201d?OpenDocument

Question:

What is the difference between the A side and the B side?

Answer:

A/B side concepts are relative to LIC and not to OS/400 or LPP PTFs. When 
a new system is shipped or when the operating system is upgraded to a new 
release, the A side and B side match. When LIC PTFs are temporarily 
applied, they are applied to the B side. If you have temporarily applied 
LIC PTFs and you are running on the A side, you will not be running with 
the PTFs.

Previous to V3R1M0, you had to be running on the A side to apply PTFs to 
the B side. When GO PTF, Option 8 is used to apply LIC PTFs, the system 
determines if you are running on the A side or the B side. If you are 
running on the A side, the LIC PTFs are applied immediately. The system is 
IPLed to the B side to apply the rest of the PTFs. If you are running on 
the B side, the system does a partial IPL to the A side to apply the LIC 
PTFs. The system is IPLed back to the B side to apply the rest of the 
PTFs.

Starting in V3R1M0, immediate LIC PTFs can be applied to the B side while 
you are running on the B side. If you are on the B side and you use GO PTF
, Option 8 Automatic IPL Y to apply immediate LIC PTFs. The system IPLs to 
the B side to apply the PTFs. The system does not IPL to the A side. 
Delayed LIC PTFs in V3R1 and beyond function the same way all LIC PTFs 
functioned before V3R1M0. Permanently applying LIC PTFs puts the PTF on 
the A side. Once the PTF is permanently applied, it cannot be removed.
