You should have gathered from the previous pagesets that PPRC commands are complicated to put together, and need to be issued in the right order. You can set up your own automation procedures to make things simpler, but IBM have developed an automation option to do this for you. GDPS stands for Geographically Dispersed Parallel Sysplex. What that mouthful means, is we can cluster several OS/390 machines together, and the machines can be several kilometers apart. GDPS will work with either PPRC or XRC (but not SRDF!).
The GDPS section is split into five parts
