Hi, Bryce:

For really large files, such as your 8 GB transaction file, use the QDBBRCDS API to do what is called "anticipatory paging", to bring in the next few blocks of data, just prior to their use (when your application actually reads the next block of records).

QDBBRCDS returns to your program immediately after initiating the asynchronous "bring" request, so your application program can continue to process the current block of records, while the "bring" is taking place.

I like the idea and all, but in this case and others that might be similar
we are talking about putting a large object into a memory pool. Now, I
don't know what you guys consider a large object, and maybe I don't know
enough about memory pools (which is probably the case). But say you need
to process a 'big' file, i'm thinking on that is like 8gigs of data or
something...maybe an inventory transaction file... and you stock that
thing in memory won't you be eating up 8 gigs of your memory from the
system? Is that really a good thing to do?

I really don't know if that is how the memory pool works, but that is the
thought that came to my mind.


Thanks
