Using 12 Ultralite and Mobilink against a Version 7 server

[former_SQLA_member1694898]

Is it possible to develop code using the new version 12 Ultralite and Mobilink that will run against a Version 7 consolidated DB? We have a legacy app that utilizes the 7 DB but would like to use some of the newer Mobilink and Ultralite functionality. We would like to use the server initiated synching of Mobilink and the Ipad / Android deployment features of Ultralite. Will this work?

The syncsa.sql script for version 12 may rely on SQL Anywhere features not in version 7. FYI, before version 10, the ML system setup for SQL Anywhere consolidated databases was installed by dbinit rather than by a syncsa.sql script.

It may work but it is NOT supported.

FWIW, you may be able to use a separate consolidated especially for the purpose of SIS. Here's how it might work:

1. Create a new SIS consolidated database with the MobiLink system tables
2. Set up the Notifier(s) in your SIS consolidated (or create an option file for (3))
3. Run a MobiLink server on the SIS consolidated
4. Route all SIS traffic, eg. lightweight polls, through the ML server in (2)

If the business logic of your SIS requires the SIS gear to be visible during synchronization, then you'd require only one consolidated handling both sync and SIS. Of course this would require the consolidated database to be a supported version of SA (from a MobiLink point of view), which is ideally the same version as MobiLink.
