I think, but may be mistaken, that the mapped database lab shows how to increase the size of a mapped file. The main point is that the file must be unnapped, closed, resized, and then remapped. This is fairly trivial for non-jmf files. For jmf files you may (or may not) have the additional complication of adjusting the header size value for the allocated space. If this is necessary then code in jmf.ijs should show the way. Some of the comments in the jmf file are a bit out of date and in unix at least it is easier to use truncate to change the size.
