Re: Is OAS obsolete now that we have 8i?

A very interesting question -

I think the key is to look at the type of functionality that each product provides and not to get too hung up on the overlap. For example, you can develop web enabled Java applications using both 8i and OAS 4, both have ORBs, both support web enabling PL/SQL applications (WebDB and PL/SQL cartridge).

Both have different models for distribution, 8i uses OPS or completely separate databases, OAS uses multi-node and distributed processing. How much of the guts of the two products are the same? Different JVMs, different ORBs. I don't know which one is faster or scales better.

If you use OAS for managing the middle tier, you can still use Java in 8i to implement portions of the business logic, much as you might implement it in PL/SQL with V7.X/8.0.

If you were to build a PL/SQL app, I'd tell you to start with WebDB and if it doesn't scale then move the app to OAS. For java I don't know how 8i performs or scales up. We need to find somebody who's got their hands on the stuff and has some information to share.

If you are building something small, there is probably no serious technical difference, though there may be a cost difference to one solution or the other.

Cheers
