My client is very experienced in ASE, and new to both ASA and to
MobiLink. They're using an existing ASE database (12.5.0, I believe)
as their consolidated, and they have a server set up for "warm
standby", using RepServer, and where they plan to place a standby
instance of the ML server.

They want to know: In the event of failure, what configuration changes
might be needed to divert synchronization requests to the standby ML
server?

I'm not a specialist in production configurations or hardware, so I
hope this post makes sense. :) Gee, I don't know what hardware
they're using in production.

They're using ASA 9.0.1.1751

Any light on the situation is appreciated!

Margaret

Well, as in most design-type questions, the answer is: it depends.

Are they willing to build fail-over in the client (i.e. code multiple ML
server addresses into their remote and have dbmlsync iterate through
them until it succeeds)?

Are they going to synchronize directly to an ML server or are they going
through a proxy (e.g. the ML redirector)?

How do their remotes initiate synchronization (e.g. the user manually
runs dbmlsync, the application has a "sync" function which calls
DBSynchronizeLog(), ...) ?

BTW: you'd probably get responses from the greater ML community if you
post ML questions to sybase.public.sqlanywhere.mobilink.
