I wouldn’t normally "jump" on something like this, but as I mentioned, I am in 
the middle of a maintenance cycle anyway.  What's one more PTF in an already 
long list.

No disrespect here to Tom and his "head's up", you, his problem etc. 
It's nice to have a head's up on a problem.     This is just something
to ponder on a Friday afternoon (and not OT either!). 

I am always curious why people "jump" after a post like this and think to 
themselves "I have to get this PTF on "because someone they know ran into the 
problem".  As Tom noted, the APAR is not marked HIPER and hasn't even hit RSU 
(at least as of a couple of days ago when I received "CONTENT(RECOMMENDED)".  

If your maintenance philosophy is to put on PTFs for a problem "some shop"
ran into, that would include all PUT maintenance and it wouldn't matter that 
Tom or anyone else you know in person or from IBM-MAIN ran into the problem or 
not.  The fact is - "someone" ran into the problem and IBM opened an APAR then 
a ++APAR fix followed by a ++PTF will be made available (which BTW, could go 
PE!). 

I am registered for ASAP for most of the z/OS FMIDs and I get 
notifications pretty much every day and review them every few days.   It's a bit
scary to see all the PE notification and read about all the potential problems 
but I resist the temptation to apply outside of RSU unless I read the 
description and think there is good chance I would run into the problem in my 
environment.
One exception for me is that I usually apply SMSVSAM PTFs as soon as I can as 
my client has a history of big impact issues with VSAM RLS when they hit. 
I have some other exceptions too, like I see PTFs via ASAP for problems like 
spin loops that lead to IPLs - but it depends on the cause / environment 
described in the APAR text. 


Regards,

Mark
