Fair’s fair, any application the size and complexity of Oracle Applications will have some bugs. But applications seems to do far better than most.

This section refers to the server size of Applications Comedy Errors. There’s another page for the client side.

• To install a new application module, it seems that you have to add the original version you have plus all patches. Not just for your new module, but for all of them. (People that implement Application’s are not expected to make mistakes.)
• The recommended sizes for your database extents are useful. However, if you follow the advice, some parts of the system won’t actually install.
• Oracle helpfully supply a program that goes through the thousands of files that it installs and checks that they’re the right ones. We’ve found at least a dozen files that it claims shouldn’t be there but in fact should be.
• After applying a patch, the shell script that starts the Concurrent Managers just vanished.
• One of the bugs that we found was because Oracle had ‘forgotten’ to port a number of forms from one environment to the one we were using. The word ‘forgotten,’ despite being inverted commas, is the actual word used by Oracle support.
