Impact of EBS R12.2 changes – WebLogic

A number of very smart people seem to think that the introduction of WebLogic is going to be a major "game changer" for E-Business Suite DBAs. There is certainly some truth to that thought. WebLogic is a completely different animal than the Apache or Oracle Application Server that we've gotten accustomed to in E-Business Suite 11i and R12.

But consider this. I suspect that most environments are fairly vanilla. When it comes to the basic degree of interaction that an E-Business Suite DBA has with the Applications Server, I suspect that the change will be largely transparent. Consider what you do with the current Applications Server product. Start and stop? That's done through AutoConfig managed scripts. Basic configuration for EBS? That's handled through AutoConfig. Why would we expect these things to change just because they've changed out the tool?

What will it change?

I'm certain that the log files will be different. The naming convention will probably change and the location of the files might change. The content of the files will certainly be different. As will the configuration files (but, again, I would expect those to be AutoConfig managed).

The big place where you will notice the WebLogic change (from an Administrator standpoint) is if you're trying to do something else with it. If you're dealing with Discoverer or deploying APEX, for example, you'll certainly get up-close-and-personal with WebLogic.

So, should you be afraid of the WebLogic change? I don't think so. Yes, custom deployments (anything that actually requires you to "deep-dive" into the configuration of WebLogic) will have a learning curve. That said, many of the components of Oracle Fusion Middleware already use WebLogic and, if you're doing any custom deployments, odds are you're also already dealing with WebLogic elsewhere and will have some familiarity by the time you go to tie it into E-Business Suite.

When you factor in these things with the fact that WebLogic is a more mature and overall better product than the current applications server used in E-Business Suite, I think that the change is probably a good thing.
