Applying remote journals for high availabilitiy

[Rob Dixon <rob.dixon@xxxxxxxxxxx>]

I have today set up remote journalling which was fairly 
straightforward.  Now I am considering how to apply the the journals on 
the remote machines to keep the files on those machines up to date.  I 
know that I have to use the RCVJRNE command with a program that I must 
write.  This doesn't seem too frightening but it may be that there are 
more problems than I realise.  Does anyone have any experience of doing 
this that they might be willing to share?

At present, I am not trying to create an automatic switchover solution.  
However, I would appreciate any tips on how to ensure that only one 
machine is available for production updating at any one time.

I doubt that it is relevant, but the source machine and one of the 
targets are on V5R1.  The second target is on V4R5.

Many thanks
