Will VALIDATE save transfer time?
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?

DASD and Cache Fast Write DS8800/DS8700
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
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).
