I'm not sure what your problem is, Gene, but it is not that
dirty records are being hidden from users due to caching.
The beauty of the single level store is that there is no such
thing as a dirty record. When you access a record, you are
accessing address of the virtual memory location where it
resides and that memory is the same for all users.

Not quite true Joe.

Sounds like RPG may be blocking the i/o of the file. In which case, while the program has done the
WRITE, the data is still in the program buffers and has not yet been passed to the DB.

Gene, DO NOT CHANGE FRCRATIO!

Instead, try adding a FEOD(n) op-code to flush the RPG program buffers to the DB. The (n) extender
was added at v5r2 and allows FEOD to flush to the DB without necessarily writing the data to disk. So
the preformance of FEOD(n) will be much better than FEOD by itself or having FRCRATIO(1).

HTH,
Charles
