Re: [ADSM-L] AIX DST patch: anyone else apply?

If you are running AIX 7 TL1 at SP 2 or SP3  or AIX 6 TL4, TL5, TL6, or TL7 at 
the latest service pack level there is a potential problem with the Daylight 
Savings Time transition.

Symptom would be a early transition to DST from standard time

See 
http://www-01.ibm.com/support/docview.wss?uid=isg3T1013017&myns=pwraix61&myne=E

It requires a reboot to circumvent or patch.
The saving grace is that it is only exposed in more recent SP levels or AIX 6 
or the latest TL of AIX 7.

Daylight Savings Time starts in most of the US on March 11.

Hmm, this is the first I've heard about a new DST issue. Anybody have an APAR 
or a link to more information?

Thanks,
Ben

Hi.......

Yes, we received the DST notification for AIX V6/V7 late Friday, 2 March 2012.  
Our AIX consultant had us use the Olsen environment and we re-booted our AIX 
V6.1 servers.  Since we are late on AIX migration from AIX v5.3.12.3 to AIX 
v6.1.7.1/3, we only had six AIX servers to modify.  Two of them are TSM systems 
(PROD & TEST).  BTW, the notification said to re-boot AIX servers by midnight 6 
March 2012 for the DST fix to work!!!

Our AIX V6.1 servers shows:

# echo $TZ
America/Chicago

Folks:
  A little late, but we are curious.

  We are running 10 TSM servers (v6.2.3.0) on 2 IBM Power 550s running AIX
6.1 TL7 SP1.

  Over the weekend, we got notified of a bug in the DST processing (apparently 
introduced via a coding change in the last year).  After considerable head 
scratching, we decided to apply the eFix because we had no way to 
verify/guarantee that all of our applications were using the default TZ (which 
was "EST5EDT" - not a custom value, and thus not at risk from the bug).

  Did other see this alert and chose to apply?  Or ignore?
