Re: Replication

Light works with a 9ias application (part of the Light package) to establish the mobile database and application on the mobile client. Once the application and database are downloaded, the database uses Advanced Replication to sync with the master when the clients are brought back to the network. While mobile, Light emulates the oracle server (and potentially the 9ias server) for a single user.

You have a master database server connected to the mobile data server (9ias) which handles the interface to the mobile clients (laptops, desktops, what-have-you). Up to 64 mobile clients per mobile server, if I remember the marketing speil right, but we're still at the 4-client dev/test phase.

We have staff working on it, with assistance from an Oracle consultant brought in for the purpose. I just deal with the master database.

Since we're doing stand-alone, we have to hand-jar the java applications (the jar wizard with Oracle Developer doesn't fit the bill somehow) so application deployment is the sticking point at the moment. We might get an answer this month, but the dev manager is doing the schedule and application details.

My understanding is that if you deploy a JSP web app using 9ias, the app can be downloaded and run on the mobile client against the Lite database, and that sort of deployment appears to run smoothly (the examples work). But we're not doing that in this case so I have no real-world experience there.
