Both SMF and DB2 have the appropriate ability to handle the time change.
As I stated in another post. No IBM subsystems care about Local time.
The only things that care are applications within those subsystems.

John,
Where does SMF use UTC? Most times are recorded as 'TIME SINCE MIDNIGHT IN
HUNDREDTHS OF A SECOND'. I have never seen a field in a SMF record for UTC
offset. Note: The new extended SMF record header does include the time in
STCKE format, but I haven't seen any records that use the new

Believe me, you either want to quiesce or unmount the zFS before dumping it.
Otherwise, you'll be waiting roughly 15 minutes for the mount operation to

FDR DUMP is a full volume operation. FDRABR DUMP allows for Select statements

You're welcome.
While RTMFing, you must have missed Note 1. of the T= parameter of the $TA
command.
Mind the small window of mis-scheduling: if you issue the command between 00:00
and 00:05, the job will not run today at all.

Hello all
I have a need to run a couple of batch jobstreams at the same time every
day.
The streams are fully developed and they run happily at the required
time(s), under control of a couple of JES 'TA' automatic commands:
£ T A0001,I=86400,T=00.05,'£VS,''S JOB,N=DLYWORK1'''
£ T
The problem is that when you issue the automatic command with a time in the
past, it will be issued immediately.
You can avoid this by scheduling it for the next day with T=24.05. T= is
calculated from the last midnight, so 24.05 means 00:05 tomorrow morning.
