Re: Recompiling an RPG pgm

Hi Seth -

You can force the records to disk with OVRDBF FILE(filename)
FRCRATIO(1). This will tell the system to force any output to disk immediately. The consequence is that you take a performance
hit.

If any of this is not accurate, someone please correct me.

You were doing fine until you hit the part quoted above. FRCRATIO(1) forces the data not only to be written to the file but also the file pages in memory to be written to the disk. This is a much bigger performance hit than what is needed to make the records visible in the file.

To turn off record blocking, using OVRDBF with SEQONLY(*NO), or in RPG IV you can also do it in the program with BLOCK(*NO) in the keywords part of the F-spec.

This will cause the records to be written to the file immedidately, which is a little performance hit, but not force the pages to be immediately written to disk, so it is not nearly as much of a performance hit as FRCRATIO(1).
