It is a real shame that IBM/Lotus didn't make this part of the
functionality actually work WITHIN the Domino infrastructure...

Subject: Traveler on i and HADR options
Sent by: domino400-bounces@xxxxxxxxxxxx
We've had great results with Domino 9 so far the week that we've been on
it.
I'm now testing Traveler on i (we have always run it on a Windows server
that was leftover from a phased out Blackberry BES oriented Domino Server).
The Traveler functions seem to work great with our test devices so far, but
i'm finding that setting it up to be highly available is going to be a bit
of a mess...
We have 2 clustered Domino servers that support mail users and have no
problem getting the external URL that the Traveler mobile devices access to
switch between whichever mail server we want to 'answer' at any given time.
The challenge is that the Traveler portion of the data (when configured for
HADR) is moved to a DB2 database... it's an easy conversion and works well,
but the data needed by the Traveler server and devices is in ONE location.
If that location is down, effectively so is Traveler functionality.
BOTH of the Traveler servers (when converted to HADR) can be pointed to the
backend DB2 database with no trouble, but the single point of failure
remains.
All of the documentation I can find mentions that the backend DB2 database
can be made highly available between servers, but so far I have not found
an easy way to do this on the IBM i. What sort of replication would keep
this backend DB2 database in synch so that either Traveler server could use
it from either location of the DB2 backend?
Has anyone tackled this type of setup yet?
