Hello (this is a long one please bare with me):

Is anyone out there familiar with a Bus-Tech Datablaster??? We currently
have this set up between our Mainframe and HP 3000/997/500 when we do a
'blast' from the Mainframe to the HP it is painfully slow - we are in a
quandry we have to pass a 18,000,000 record file from the Mainframe to the
HP and we are looking for ways to get this process to work faster.
Unfortunately there are no FTP capabilities on the Mainframe.  So we are
stuck with the datablaster.

I have been trying a multitude of options, and my mainframe people keep
telling me if I can increase my 'blocking factor' the process should go
faster, I keep explaining to them that the HP doesn't really care about
blocking factor. After more discussion, I was told to set my REC= to the
blocking factor on the Mainframe; ok, I can do that, of course what happens
next is 'EXTENT SIZE EXCEEDS MAXIMUM'  if I don't use the DISC= on my FCOPY
the command works, but defaults to the 1023 file size.

I've included the JCL from the job that runs on the HP, this runs
simultaneously with a job on the Mainframe to get the file transferred. If
anyone knows anything, well you will be helping a truly frazzled human
being!

Thanks,  Ceceil Barbarino
