Platform requirements for IBM Daily Compression Generator:
Operating systems: DOS box. Any "Wintel" configuration will do. With modest modification, UNIX® and Linux® as well.
Installation instructions for IBM Daily Compression Generator:
Simply download the two files (DailyCompress.exe and DailyDecomp.exe).
Running Daily Compression Generator
- At the constructor side (where the delta is produced from yesterday's version and today's version): Make a clean directory and store DailyCompress.exe there. From a DOS box, run the following:
DailyCompress <full path to yesterday's directory> <full path to today's directory>.
Suppose that c:\alpha\diryesterday contains yesterday's version and d:\alpha\today\directory -- today's, and that in a clean directory named c:\testing\alpha, you stored DailyCompress.exe. In a DOS box, "cd c:\testing\alpha", and in it run the following:
DailyCompress c:\alpha\diryesterday d:\alpha\today\directory
The whole produced directory (the whole contents of c:\testing\alpha), except, possibly (for ease of explanation, we can forget this exception) DailyCompress.exe, is to be shipped to the other side (it can be made into one file using standard WinZip).
- At the other side, make a clean directory, put the contents of the arriving directory into it, and add DailyDecomp.exe into it. In a DOS box, run the .bat file DailyDecompress, as follows:
DailyDecompress <path to yesterday's build> <path to today's build (yet to be produced)>
DailyDecompress.bat is one of the files produced by Daily Compression Generator on the constructor side.
