Re: Simulate Database Writes

There's an outline and sample C program that I wrote about 5 years ago on my web site under

    http://www.jlcomp.demon.co.uk/block.html

Bear in mind that the write has to be at the equivalent of an oracle block boundary, and you need to open the file and write to the file using the same calls that dbwr does - you might want to "truss" a database startup before writing the C to find out what those calls are.
