which I will now study as it appears to have a way round this.

Subject: Applying remote journals for high availabilitiy

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
