RE: Accessing a file in memory

["Ingram, Terry (USE)" <Terry.Ingram@xxxxxxxxxxx>]

It almost sounds like you want to do a SETOBJACC.  If nothing else, this
could be a quick thing to try.  Just can do SETOBJACC for each of the files
you want to load into memory.  If it doesn't work, nothing lost with minimal
time invested.  It's been a while since I've used it, but think if you look
in the job log, it will tell you how much memory is left.  So, if you files
are too large to load into memory I think it displays a message, but the job
continues.

One time, I heard the suggestion to create a new shared pool that allocates
enough memory to load all these files, then use the SETOBJACC specifying
your new shared pool.  Since nothing else will be using it, all the memory
will belong to that job.  And then delete the shared pool when you are done.
Granted, that is a generic comment and doesn't take into account how much
memory you really have.
