Re: Q: Oracle 8 vs. 8i for OAS/Java app?

David,

The applications that you develop on the OAS platform will, for the most part, be portable to Oracle 8i. From my understanding, there is only one area that will need modification... the connection management. You will no londer need to open and close jdbc connections. The database server will manage that for your app. If you can extract that functionality into a library that can detect the environment, then the code you write will, literally, be binary portable from OAS to 8i (by binary portable, I mean bytecode portable, without the need for recompilation).

This, of course, is all true in theory, but I'll be able to give you a concrete assessment in Feb about how realistic this is (because I'm doing a few courses in the first week of Feb, one on Java in the OAS, and another on Java in 8i)

Hope this helps,

Eddie
