Will VALIDATE save transfer time?

2013-05-16 Thread Ken Leidner
I asked this earlier using the INSTALL command to perform the writing 
of the home address and was correctly pointed out that the command is 
not valid on the device.  But the person missed the true point of my 
question.


So now using VALIDATE to write the home address and clear off the 
tracks, does anybody know the answer to my question?


I am running Global mirror on an IBM  8300 DASD box.  I soon will be
TDMFing the volumes to a new 8870 box and starting a new Global
Mirror session from the new 8700 box.  I have some volumes that use
to be active (had datasets on them), but since have been returned to
a free status.

My question is would running ICKDSF with the VALIDATE option of the INIT
command on the free volumes save me transfer time?  Either with TDMF
moving the volume or Global Mirror syncing the volume.  The thought is
that maybe since INSTALL writes the home address on the volume all of
the user data is removed and the volume would compress very well and
therefore transfer very fast.   True?

What process is running when the error occurs?

DASD and Cache Fast Write DS8800/DS8700

2012-10-30 Thread Ken Leidner
Does setting the DASD FW  or Cache FW on or off still exist on the 
DS8800/DS8700 devices.  I know when they first came out for a 3990-6 
controller, the performance different was night and day.


But on the newer devices isn't it always on?  Can I really still turn 
it off?  Do I still need to check to make sure it is on?

Re: SYNCSORT - Save a data item for use in OUTREC output

2012-07-09 Thread Ken Leidner
As a concept, I would copy the first record to a new dataset (using 
sort) and expand the record by one character - a blank.  In a second 
OUTFIL statement I would expand all of the other records by the same 
1 character - a blank.


Then I would JOIN the two expanded datasets using the added blank as 
the key.  I would tell the JOIN that the records are already 
sorted.  Then in the JOIN's REFORMAT statement you can add the field 
from the one record file to where ever you want in all of the records.


You can decide if the first record record should be in both expanded 
files or not (I would think so).
