The Oracle Developer Suite 10gR2 was released a short time ago, and i thought there are no troubles to migrate from 10gR1 to 10gR2, but there are. Oracle Developer Suite 10g Release 1 is an enhanced version of the Oracle 9.x Developer Suite, you can see that by the version-number 9.0.4. That means the forms have to be recompiled, and there is a huge change in Reports. Reports until 10gR1 were 6i Reports. With 10gR2 they are fully reloaded. Image
