Hello,

I am working on a project at which I need to replicate a
Sybase ASE (transactionally) to another location (where it
doesn't need to be ASE). Instead of immediately paying for
Sybase Replication Server, I would like to evaluate a
product first, and build a prototype. I was wondering if
MobiLink and ASA would be a good choice for this, or is
MobiLink primarily built for mobile applications, and should
I best look elsewhere? If not, maybe someone has a better
idea?

Thanks in advance,
Koen

So far you have only given us one requirement for the
replication/synchronization which is that it has to be done transactionally.
That requirement itself can have different interpretations. For example Rep
Server replicates only committed transactions *and* maintains transactional
boundaries - commit points - when replicating the changes to the primary
database. MobiLink synchronizes only committed transactions *but* since it
is a synchronization technology what gets moved is the summary of the
changes.

I am aware of that difference. It doesn't make much of a
difference for this project, though.

We've already made up our minds and we have reached a deal
with Sybase for the evaluation of Rep Server. Thank you for
your reply.

ASA and MobiLink are fantastic technologies for having "remote"
databases (i.e. databases running in geographically separate locations
or in environments where network bandwidth/stability are not guaranteed).

If you feel that MobiLink synchronization can work within your
environment, then you should look at your database and application
requirements to make sure that ASA will fit. For the most part, if ASA
supports the OS your are targetting (MS-Windows, Solaris, HP-UX, Linux,
etc...) and has a programming API you plan on using (ODBC, JDBC, .NET,
etc...), then ASA is likely a great fit for you as well.

If you are interested in giving SQLAnywhere a try, there is the Getting
Started page which points to the Developer Edition, a fully featured
free download:

Hope this helps,
